If you have lost the receipt number for your pending green card application, you can still check its status. The three practical routes are calling the USCIS Contact Center at 800-375-5283 with your A-Number and personal information, recovering the receipt number from payment records or old USCIS mail, and, as a last resort, filing a Privacy Act records request through the USCIS FIRST portal. The receipt number is a 13-character code (three letters followed by ten digits) printed on the Form I-797C, Notice of Action, that USCIS mails after accepting a filing, so it is often recoverable from places you may not have thought to check.
Try to Recover the Receipt Number First
Before working around the missing number, spend an hour trying to find it. The Form I-797C prints it in the upper left corner of the notice, and copies of that notice tend to exist in more places than people expect.
Payment Records
If you paid the filing fee by check, ask your bank for a copy of the canceled check. USCIS prints processing information on the back when the check clears, and that information often includes the receipt number. For credit or debit card payments, pull up your transaction history and locate the USCIS charge. The card record itself will not show the receipt number, but the exact date and amount give a phone representative a concrete anchor to find your case.
Old Mail, Email, and Your Attorney
Search stored paper mail for the I-797C, and check your email (including spam and junk) for any electronic confirmation from USCIS if you filed online. If an attorney or accredited representative filed on your behalf, they keep a copy and can send it to you the same day.
Find Your A-Number
If the receipt number is genuinely gone, your Alien Registration Number is the next best identifier. The A-Number is an eight- or nine-digit number preceded by the letter “A” that USCIS assigns to noncitizens who have been granted immigration benefits or are in removal proceedings. It stays with you across every application, and USCIS agents use it to pull your entire file.
You can find your A-Number on an immigrant visa stamp in your passport, labeled “Registration Number” in the upper right. It also appears on any green card you have previously held, on older I-797 approval notices, and on Employment Authorization Documents. Having it ready before you call makes every subsequent step faster.
Call the USCIS Contact Center
The most direct route to a status update without a receipt number is the USCIS Contact Center at 800-375-5283 (TTY 800-767-1833), open Monday through Friday from 8 a.m. to 8 p.m. Eastern time.1USCIS. USCIS Contact Center A Tier 1 representative will try to locate your case using your name, date of birth, and A-Number. For privacy reasons they generally will not read the receipt number back to you, but they can confirm whether your application is pending, approved, or waiting on action from you.
If Tier 1 cannot resolve the question, USCIS escalates the call to a Tier 2 Immigration Services Officer. Before escalation, the representative will ask whether you consent to a text notification when the officer is ready to call back. If a callback is needed, you receive a text indicating that USCIS will call within a 30-minute window, and you can accept that window or request a different time.2Department of Homeland Security.

Link the Case to a myUSCIS Account
Once you have recovered the receipt number, add the case to a free account at myuscis.gov. If you filed online, the account already shows your case status, history, and any pending requests for evidence. If you filed on paper, you can add the case by entering the receipt number, and for IOE-prefix cases you will also need the Online Access Code printed on your Account Access Notice.3USCIS. How to Create a USCIS Online Account
There is an obvious catch here for anyone who has already lost the receipt number, but once you get it back, linking the case means you no longer depend on paper notices. The account stores every notice USCIS issues, sends alerts when status changes, and lets you upload evidence or respond to a Request for Evidence directly.4USCIS. Checking Your Case Status Online
Request an In-Person Appointment
USCIS no longer permits walk-in scheduling the way the old InfoPass system did. For most services, including retrieving a lost receipt number or getting a general case update, you have to call the Contact Center first. Only after a Tier 2 officer decides the issue cannot be handled by phone will USCIS schedule a field office appointment for you.
When you get one, bring every piece of identification and USCIS correspondence you have: your passport, any prior green cards, old I-797 notices, your A-Number, and a government-issued photo ID. Officers at the field office have full access to your file and can confirm status, list any missing documents, and answer questions in real time. Arrive at least 15 minutes early. If you are late, USCIS will cancel the appointment and you have to start the scheduling process over.
File a Privacy Act Records Request
When phone calls and appointments have not produced what you need, you can file a formal request for your own immigration records under the Freedom of Information Act or the Privacy Act. The Privacy Act gives individuals the right to access records about themselves held by federal agencies, which includes your USCIS file.5Office of the Law Revision Counsel. 5 U.S. Code 552a – Records Maintained on Individuals
As of January 22, 2026, USCIS requires all FOIA and Privacy Act requests to be submitted online through the FIRST portal at first.uscis.gov. You will need a USCIS account if you do not already have one. Paper submissions by mail or fax are generally no longer accepted except in limited circumstances, such as when the requester is incarcerated.6USCIS. Request Records Through the Freedom of Information Act or Privacy Act Provide as much identifying information as possible: full name, date of birth, A-Number, and a description of the records you want, in this case your receipt number and case status. The drawback is time. Requests to USCIS routinely take several months, so this is a last resort rather than a quick fix.
Why USCIS Won’t Just Read You the Number
The reason a Contact Center representative will not simply state your receipt number aloud is a combination of federal privacy laws. The Privacy Act of 1974 requires agencies to verify your identity before releasing personal records, which limits what a phone representative can share.5Office of the Law Revision Counsel. 5 U.S. Code 552a – Records Maintained on Individuals Separately, federal law restricts Department of Homeland Security employees from disclosing certain immigration information, particularly for applicants in sensitive categories such as victims of trafficking or domestic violence.7Office of the Law Revision Counsel. 8 U.S.C. 1367 – Penalties for Disclosure of Information
Expect to verify your identity at every step. Having your A-Number, a government-issued ID, and any previous USCIS correspondence in front of you makes each interaction go faster.
Why It Matters to Keep Tracking the Case
Losing sight of a pending green card application is not just inconvenient. USCIS sends time-sensitive notices to the address on file, and if you are not watching for them, deadlines slip by. A Request for Evidence typically gives you about 87 days to respond, and if the notice sits unopened or goes to an old address, USCIS can treat the petition as abandoned and deny it. USCIS may also schedule a biometrics appointment at an Application Support Center, and failing to appear without rescheduling in advance can lead to denial of the underlying application.8USCIS. Preparing for Your Biometric Services Appointment Once an application is denied for abandonment, the only path forward is to refile and pay new fees. That is the reason to work through the recovery methods above rather than wait for the next piece of mail.
