The Illinois ARDC Change of Address update is the official notice every Illinois-licensed attorney must submit to the Attorney Registration and Disciplinary Commission within 30 days of any change to their registered business or residential address, telephone number, or email on file. Filing this update through the ARDC Attorney’s Portal keeps the lawyer’s Master Roll record accurate and protects the licensee from registration delinquency, missed disciplinary correspondence, and removal from the roll of attorneys authorized to practice law in Illinois.
The duty to keep your address current is not a courtesy. It is a hard mandate written into Illinois Supreme Court Rule 756(c) and reinforced by service-of-process rules in Rule 764. According to the ARDC’s most recent Annual Report, the Commission tracks more than 99,000 active and inactive Illinois attorneys, and tens of thousands of address updates flow through the Attorney’s Portal each year, making the change-of-address process one of the most common compliance tasks Illinois lawyers perform.
Here is what this guide covers, step by step:
- 📍 Exactly which fields to fill in on the ARDC Attorney’s Portal Change of Address screen, with sample entries from real attorney scenarios.
- 🗂️ The documents, ARDC number, and account credentials you need before you log in.
- ⏱️ The 30-day deadline under Rule 756(c), the consequences of missing it, and how to fix a late update.
- 🧾 Three full filer walkthroughs, including a solo practitioner, an in-house counsel relocating out of state, and a retiring attorney switching to inactive status.
- ⚖️ The 12 most common mistakes attorneys make, the do’s and don’ts, and 12+ FAQs that resolve field-level confusion before you click submit.
What the ARDC Change of Address Is and Who Must File It
The ARDC Change of Address is a self-service update inside the Attorney’s Portal that lets every registered Illinois attorney edit the contact information the Commission keeps on the Master Roll of Attorneys. The update is not a “form” in the traditional PDF sense. It is an electronic record change that the ARDC accepts online, by mailed written notice to its Chicago office, by email to its registration team, or by phone with a registration specialist. Each method writes to the same database that drives the public lawyer search and the disciplinary correspondence queue.
Every attorney admitted to the Illinois bar must file the update, regardless of practice status. Active attorneys, inactive attorneys, retired attorneys, judges on the inactive roll, house counsel registered under Rule 716, and attorneys on disability inactive status all carry the same 30-day duty under Rule 756(c). Out-of-state attorneys who hold an Illinois license while practicing elsewhere are not exempt. The duty attaches to the license, not to the lawyer’s location.
The form solves a deceptively simple problem. Without a current address, the ARDC cannot mail your annual registration packet, the Clerk of the Supreme Court cannot serve disciplinary notices, opposing counsel cannot rely on the public roll, and clients cannot find you. A stale address triggers registration delinquency, late fees, and in serious cases removal from the Master Roll under Rule 756(g). The form’s revision date is not printed because the portal record updates dynamically, but the governing rule was last amended effective October 1, 2024, and the ARDC registration FAQ page reflects that version.
Before You Start: Documents and Information You Need
Before you log into the Attorney’s Portal, gather the following so you do not lose your session midway. The portal times out after roughly 20 minutes of inactivity, and a partially completed update does not save.
- Your ARDC number. This is the eight-digit registration number printed on your annual registration card. Without it, you cannot log in. If you forget it, retrieve it from the public lawyer search using your name.
- Your portal password. If you have never logged in, request a temporary password through the portal’s “First Time User” link. Lost passwords trigger an email reset that can take up to 24 hours.
- Your new business address. Use the full street address, suite or floor number, city, state, and ZIP+4. The portal validates against USPS records and rejects vague entries like “downtown office.”
- Your new residential address. The ARDC requires both. The residential address is private by default and is used only for ARDC mailings if you elect it as your designated address for service.
- Your new business telephone number. Include area code in the format 312-555-0123. Extensions go in the dedicated field.
- Your new email address. The ARDC sends registration reminders, disciplinary notices, and CLE confirmations to this address. A typo here can cause you to miss a registration deadline.
- The effective date of the change. Enter the actual date the new address takes effect, not the date you log in. Future-dating is allowed up to 30 days.
- Your new firm or employer name, if it changed. A firm change often triggers an MCLE record update too, so have the firm’s full legal name ready.
- Your designated address for service election. Decide before logging in whether your business address or your residential address will be your public address of record under Rule 764.
- A backup contact method. If the portal goes down, you will need the ARDC Chicago office address (130 East Randolph Drive, Suite 1500, Chicago, IL 60601) or the Springfield office address to mail a written notice.
If any of these items are missing, the portal will either reject the submission or save an incomplete record that the ARDC may flag as noncompliant. The Commission has discretion under Rule 756(c) to treat a half-completed update as no update at all.
Where to Get the Form and How to Access It
Illinois does not publish the Change of Address as a downloadable PDF. The official update lives entirely inside the ARDC Attorney’s Portal, which the Commission launched to replace paper change-of-address letters. Once inside the portal, the update sits under the My Profile tab, in the Contact Information subsection, with separate panels for business address, residential address, telephone, and email.
Three alternative channels exist for attorneys who cannot use the portal. The first is a written letter mailed to the ARDC’s Chicago office at 130 East Randolph Drive, Suite 1500, Chicago, IL 60601. The letter must be signed, must include the attorney’s full name, ARDC number, old address, new address, and effective date, and must be received within 30 days of the change. The second channel is email to the Commission’s registration team at registration@iardc.org, which the ARDC contact page lists as the registration mailbox. The third is a phone call to the Chicago office at 312-565-2600 or the Springfield office at 217-522-6838, where a registration specialist will enter the change for you while you stay on the line.
The portal is the fastest channel. It writes to the Master Roll in real time, generates an automatic email confirmation, and timestamps the change for compliance with the 30-day rule. The mail channel takes 7 to 10 business days to post. The email channel takes 2 to 4 business days. The phone channel posts the same day but requires identity verification through your ARDC number and date of admission.
Step-by-Step: How to Fill Out the ARDC Change of Address Line by Line
The portal walks you through eight discrete fields and one election. Each field gets its own H3 below, with the exact field name as it appears on the screen.
Field 1: ARDC Number (Login Screen)
The login screen asks for your ARDC number, the eight-digit identifier the Commission assigned when you were admitted. Type the number with no spaces, no dashes, and no leading letters. For example, Maria Lopez enters 06298745 even though her registration card shows it as 6298745; she pads the leading zero because the portal expects exactly eight digits.
A common nuance arises when an attorney was admitted before 1980 and carries a six-digit ARDC number. The portal still requires eight digits, so pad with two leading zeros. The most common mistake here is typing the Illinois bar exam number instead of the ARDC number, which causes an immediate “user not found” error and locks the account after five tries. Filers often hold the misconception that the ARDC number is the same as the Supreme Court roll number, but they are different identifiers maintained by different offices.
Field 2: Password (Login Screen)
The password field accepts the case-sensitive password you set during your last registration cycle. If this is your first portal login since the 2023 rebuild, click “First Time User” and follow the email verification flow. Marcus Hall, who has not logged in since 2019, requests a reset, receives a temporary password, and changes it to a passphrase before continuing.
The nuance is that temporary passwords expire after 72 hours. The mistake to avoid is reusing a password from another bar association portal, which the ARDC’s security scanner flags. The misconception is that the ARDC stores your password in plain text, which it does not; it hashes the value, so even staff cannot tell you what it is.
Field 3: Business Address Street Line 1
Once inside, the Business Address panel asks for Street Line 1. Enter the building number and street name in standard USPS format, all in mixed case. For example, Aisha Patel enters 225 West Washington Street for her new office in the Loop.
The nuance is suite or floor numbers, which belong on Street Line 2, not Street Line 1. The mistake of cramming “Suite 1800” into Street Line 1 causes the USPS validator to reject the address and revert the field to its prior value without warning. The misconception is that the ARDC uses the address only for mail; in fact, the address feeds the public Lawyer Search, so a typo becomes publicly visible to clients and judges.
Field 4: Business Address Street Line 2
Street Line 2 is optional but matters when the building has multiple suites. Enter Suite 1800, Floor 22, or Unit B exactly as the lease shows. Aisha Patel enters Suite 1800 on this line.
The nuance is P.O. boxes. If your business mailing address is a P.O. box, place PO Box 1234 on Street Line 1 and leave Line 2 blank. The mistake is entering a private mail receiver like a UPS Store address without identifying the suite, which can cause mail to be returned to the ARDC and trigger a “bad address” flag. The misconception is that you cannot use a P.O. box at all; you can, as long as it is a valid USPS-issued box and you also list a residential address.
Field 5: City, State, and ZIP
The portal splits city, state, and ZIP into three subfields. Type the city name in mixed case, choose the state from the drop-down, and enter the nine-digit ZIP+4 if you know it. Marcus Hall enters Chicago, selects IL, and types 60601-6219.
The nuance is out-of-state addresses. Illinois attorneys who practice in another state still use this same field, and the state drop-down accepts every U.S. state, D.C., and recognized territories. The mistake is entering only the five-digit ZIP, which still saves but causes USPS sorting delays of 2 to 3 days. The misconception is that the ZIP+4 is optional for compliance; while the ARDC accepts five digits, the USPS ZIP Lookup tool is the safer source.
Field 6: Business Telephone
Enter the direct dial business phone in the format 312-555-0123, with hyphens and area code. The extension field sits to the right and accepts up to six digits. Maria Lopez enters 312-555-0188 with extension 204.
The nuance is shared firm lines. If the number rings the firm reception, list it anyway and use the extension field for your direct line. The mistake is entering a personal cell number in the business phone field, which then publishes on the public roll. The misconception is that the ARDC keeps the phone number private; it does not, unless you mark the residential record as your designated address for service and leave the business phone blank.
Field 7: Email Address
The email field accepts one address only. Use a professional address that you check daily. Aisha Patel enters aisha.patel@washingtonlawllc.com.
The nuance is shared inboxes. Avoid generic addresses like info@firm.com because the ARDC sends time-sensitive registration reminders that may not reach you. The mistake is typing a personal Gmail without confirming it; a typo here means you will miss the annual registration email blast in November and risk delinquency on January 31. The misconception is that the ARDC will mail a paper reminder if the email bounces; it does not, because Rule 756 places the duty to keep contact information current entirely on the lawyer.
Field 8: Residential Address
The Residential Address panel mirrors the Business Address panel with the same Street Line 1, Street Line 2, City, State, and ZIP fields. The ARDC requires this even if you work from home. Marcus Hall, who works from home, enters his home address in both panels and then uses the designation toggle to mark only one of them as public.
The nuance is shared residences with another attorney. Each attorney must list the same physical address on their own record; do not merge accounts. The mistake of leaving the residential address blank because “it’s the same as business” causes the portal to halt the submission with a red error banner. The misconception is that the residential address always shows on the public roll; by default, it is private, and it becomes public only if you elect it as your designated address for service.
Field 9: Designated Address for Service Election
After both addresses are saved, the portal asks which address is your Designated Address for Service under Rule 764. Choose business or residential. The selected address publishes on the public Lawyer Search and receives all ARDC and disciplinary mailings. Janet Reilly, retiring solo, designates her residential address because she no longer maintains a business office.
The nuance is that house counsel under Rule 716 must designate the employer’s business address. The mistake is choosing residential out of habit, then forgetting to switch back when you join a firm; this causes ARDC mail to arrive at your home and may expose your home address publicly. The misconception is that you can designate “neither,” which is not allowed; one address must always be public for service purposes.
Field 10: Effective Date
The final field is the effective date of the change. Use MM/DD/YYYY format. Aisha Patel enters 07/15/2026 because that is the date her new lease begins.
The nuance is back-dating. If the move already happened, enter the true historical date, even if it is more than 30 days ago. The portal still accepts the late update and timestamps the submission for compliance review. The mistake is entering today’s date for a move that happened weeks ago, which can later be construed as a misrepresentation if the ARDC audits your record. The misconception is that future-dating triggers an automatic publish on that date; it does not, because the change posts immediately and the effective date is metadata only.
Field 11: Submit and Confirmation
After review, click Submit Changes. The portal returns a confirmation screen with a transaction ID and emails a copy to the address on file. Save the email or screenshot the confirmation. Marcus Hall prints the confirmation page to PDF and stores it in his compliance folder.
The nuance is that the email confirmation goes to the new email address if you changed it, so check that inbox first. The mistake is closing the browser before the confirmation loads, which sometimes voids the submission. The misconception is that the ARDC will call to verify; it will not, because the portal login itself is the verification.

How to File the Completed Form
The portal channel is the default. Log into the ARDC Attorney’s Portal, open My Profile, edit each field described above, click Submit Changes, and save the email confirmation. There is no fee. Processing is immediate. The confirmation email is your proof of filing.
The mail channel is for attorneys without internet access or those changing more than just contact information. Mail a signed letter to the ARDC Chicago office at 130 East Randolph Drive, Suite 1500, Chicago, IL 60601, or to the Springfield office at 3161 West White Oaks Drive, Suite 301, Springfield, IL 62704. There is no fee. Processing takes 7 to 10 business days. Send the letter by USPS Certified Mail with Return Receipt; the green card is your proof of filing.
The email channel writes to registration@iardc.org. Attach a signed PDF letter or write the change in the body of the email. There is no fee. Processing takes 2 to 4 business days. The auto-reply you receive is your proof of filing; print or save it.
The phone channel uses 312-565-2600 (Chicago) or 217-522-6838 (Springfield). The specialist verifies your identity by ARDC number and date of admission, enters the change while you wait, and offers to email a confirmation. There is no fee. Processing is same-day. The confirmation email is your proof of filing.
What Happens After You File
The ARDC posts the change to the Master Roll of Attorneys within minutes for portal submissions, hours for phone, days for email, and up to two weeks for mail. The public Lawyer Search reflects the new designated address as soon as the record posts. Annual registration mailings, disciplinary notices, and CLE communications begin routing to the new address on the effective date.
If you elected a new email, the next registration cycle confirmation in November will arrive at that address. If you missed the 30-day window, the ARDC may send a compliance letter asking you to confirm the change in writing, but it does not automatically assess a penalty. Repeated late updates can support a finding of noncompliance under Rule 756(c) if disciplinary correspondence later goes undelivered.
The Commission does not issue a paper certificate after a change of address. Your transaction ID and confirmation email are the official record. Keep them for at least three years to align with the Commission’s audit window.
Mistakes to Avoid When Filling Out the Form
- Typing your bar exam number instead of your ARDC number causes login failure and account lockout after five tries.
- Cramming “Suite 1800” into Street Line 1 causes USPS validation to reject the address and silently revert the field.
- Leaving the residential address blank because it matches your business address causes the portal to halt the submission with a red error banner.
- Designating “neither” address for service is not allowed and forces the portal to reject the update.
- Entering a personal cell number in the business phone field publishes the cell number on the public roll.
- Using a typo in your email address causes you to miss the November registration reminder and risk January 31 delinquency.
- Future-dating the effective date assuming the change will publish on that date is wrong; the change posts immediately.
- Closing the browser before the confirmation loads can void the submission and leave the old record in place.
- Submitting only an email change while leaving the address fields outdated leaves the Master Roll partially stale and triggers a compliance flag.
- Failing to update within 30 days of the move violates Rule 756(c) and can support a finding of noncompliance.
- Mailing the change without certified return receipt leaves you with no proof if the letter is lost.
- Forgetting to switch the designated address for service after joining a firm exposes your home address publicly until you fix it.
Do’s and Don’ts
Do:
- Do log into the portal within 30 days of any address, phone, or email change because Rule 756(c) makes that the hard deadline.
- Do verify the ZIP+4 with the USPS ZIP Lookup so the USPS validator does not reject your entry.
- Do save the confirmation email and the transaction ID because they are your only proof of compliance.
- Do designate a single address for service, because every attorney must have one public mailing address under Rule 764.
- Do update both business and residential records together, because a partial update can be flagged as incomplete.
- Do print the confirmation to PDF and file it in your compliance folder for at least three years.
Don’t:
- Don’t share your ARDC portal password with paralegals or assistants because that violates the Commission’s terms of use.
- Don’t use a generic firm inbox like info@firm.com because critical registration emails can be missed.
- Don’t enter a UPS Store mailbox without the suite number because the ARDC may flag it as a bad address.
- Don’t future-date the effective date hoping to delay public posting because the change publishes immediately.
- Don’t ignore an ARDC compliance letter because silence can escalate to a Rule 756(g) removal proceeding.
- Don’t try to update through the ISBA, your local bar association, or your firm’s HR portal because none of them write to the ARDC’s Master Roll.
Pros and Cons of Filing on Your Own vs. With Help
Pros of filing on your own:
- It is free, because the ARDC charges no fee for any change of address.
- It is fast, because the portal writes to the Master Roll in real time.
- You control the designated address for service election directly.
- You receive the confirmation email immediately, with no middleman delay.
- You learn the portal, which you will use again every November for annual registration.
Cons of filing on your own:
- A typo in any field is your responsibility under Rule 756(c).
- The 20-minute portal timeout can frustrate first-time users.
- Password resets take up to 24 hours, which can push you past the 30-day deadline.
- The portal does not warn you if your designated address election conflicts with Rule 716 house counsel rules.
- You must track the 30-day deadline yourself because the ARDC does not send reminders before the change.
Filing Channels at a Glance
| Channel | Key Detail |
|---|---|
| Online Portal | Fastest, real-time, free, immediate confirmation email |
| Mail to Chicago or Springfield | 7 to 10 business days, send certified mail for proof |
| Email to registration@iardc.org | 2 to 4 business days, auto-reply is proof of filing |
| Phone (312-565-2600 / 217-522-6838) | Same-day, identity verified by ARDC number and admit date |
Change of Address vs. Change of Status
| Change Type | What It Updates |
|---|---|
| Change of Address | Business address, residential address, phone, email, designated address for service |
| Change of Status | Active, inactive, retired, disability inactive, judicial, house counsel under Rule 716 |
A change of address never changes your active or inactive status, and a change of status does not by itself update your contact information. Janet Reilly, for example, files both updates on the same day because retirement involves a status switch and a designated-address switch at once.

FAQs
Q: Do I have to update my address if I move only a few blocks?
Yes. Any change to the registered address triggers the 30-day update duty under Rule 756(c), regardless of distance.
Q: Is there a fee to file the change of address?
No. The ARDC charges no fee for any contact information update through any channel.
Q: Can my paralegal log into the portal and update my record for me?
No. The portal terms require the licensed attorney to log in personally; sharing credentials violates ARDC terms of use.
Q: Do I write my home address or my office address as the designated address for service?
Yes, choose one. Most active attorneys designate the office address, while retired or solo home-based attorneys often designate the residential address.
Q: What if my new building has only a P.O. box?
Yes, P.O. boxes are accepted. Place “PO Box 1234” on Street Line 1, leave Line 2 blank, and provide a valid residential address as well.
Q: Do I list my cell number or my office line in the Business Telephone field?
No to a personal cell unless you have no office line. The field publishes on the public roll, so most attorneys use a direct office line with extension.
Q: Can I list more than one email address?
No. The portal accepts only one email; choose the address you check daily.
Q: What if I miss the 30-day deadline?
Yes, you can still update at any time. File immediately and keep the confirmation; repeated late updates can support a Rule 756(c) noncompliance finding.
Q: Do I need to notify the Clerk of the Supreme Court too?
No. Updating the ARDC record is sufficient because the Clerk’s roll pulls from ARDC data.
Q: Will my residential address show on the public Lawyer Search?
No, unless you elect it as your designated address for service. By default the residential record is private.
Q: Do I need to file a separate change of status if I am retiring?
Yes. Retirement requires both a Change of Address (to redirect mail) and a Change of Status (to switch from active to retired) under Rule 756(a)(5).
Q: Can I update my address by faxing a letter?
No. The ARDC retired its registration fax line; use the portal, mail, email, or phone instead.
Q: Is the effective date the date I sign the form or the date I move?
Yes, use the actual move date in MM/DD/YYYY format, not the date you log into the portal.
Q: Do I need to confirm receipt with the ARDC after submitting?
No. The portal confirmation email, the email auto-reply, the certified mail green card, or the phone-call confirmation email is sufficient proof of filing.
