How to add a paper-filed case to your USCIS online account
If you mailed your green card packet, it won't show up in an online account on its own. Here's how to link it, in plain English.
The short answer
A case you mailed to USCIS won't appear in an online account on its own. You add it yourself: sign in at my.uscis.gov, choose "Add a paper-filed case," and enter three things: your receipt number, your Online Access Code, and your date of birth. The Online Access Code comes on a separate letter USCIS mails you, called the Account Access Notice.
What adding a paper-filed case actually means
When you file a green card form online, USCIS ties it to your online account automatically. When you mail a paper form to a USCIS address instead, no account is attached to it yet. The case exists in USCIS's system, but your online account and your mailed case start out as strangers. Adding a paper-filed case is the step that introduces them, so your mailed case shows up on your account dashboard.
Most couples filing a marriage green card from inside the U.S. mail their packet. The main green card application (Form I-485, the application to become a permanent resident) still has to be mailed for marriage-based cases as of 2026, so this is the normal situation, not an edge case. The payoff: once your case is linked, you get an email or text alert every time the status changes, instead of refreshing a status page by hand or waiting on the mail.
One thing to clear up first, because three different USCIS numbers get mixed up all the time:
- Your receipt number is the number for one specific case: three letters followed by ten digits, like IOE1234567890. It's printed on the receipt notice USCIS mails you (Form I-797C).
- Your Online Access Code is a one-time 14-character code that unlocks the link between a mailed case and your account. It comes on its own letter, the Account Access Notice.
- Your USCIS online account number is the ID for your account itself, not for any case. You don't need it to add a paper case.
For the full breakdown of how these differ, see the guide on where to find your receipt number and what an A-number is.

The Process
How to add your paper-filed case, step by step
The whole thing takes about ten minutes once you have your two notices in front of you.
- 1
Create a free myUSCIS account (or sign in to yours)
Go to [my.uscis.gov](https://my.uscis.gov) and choose Sign Up. Enter an email address, agree to the terms, and set a password of at least eight characters with an uppercase letter, a lowercase letter, and a special character. USCIS then sets up two-step verification, so every login sends a one-time code by authentication app, text, or email. Save the backup code it gives you somewhere safe. Already have an account? Just sign in.
- 2
Find your receipt number
Pull out the receipt notice USCIS mailed you (Form I-797C, Notice of Action). Your receipt number is near the top: three letters, then ten digits. If you filed several forms together (say the petition, the green card application, the work permit, and the travel permit), you got a separate receipt notice for each, each with its own receipt number.
- 3
Find your Online Access Code
Look for a different letter, the USCIS Online Account Access Notice. This is not your receipt notice. It's a separate mailing whose whole job is to give you the 14-character Online Access Code you need to link your case. If you haven't received it yet, that's common, and the section below on lost codes covers what to do.
- 4
Choose "Add a paper-filed case"
Once you're signed in, open your account menu and choose "Add a paper-filed case." USCIS also has an official video walkthrough of this exact screen if you want to follow along.
- 5
Enter your three pieces of information
Type in your receipt number, your Online Access Code, and your date of birth. Enter the receipt number exactly as printed, with no spaces. Submit it, and your case attaches to your dashboard, right alongside anything you filed online.
What you can and can't see after you link a paper case
This is the part almost every other article gets wrong, so it's worth slowing down on. What your linked paper case lets you do depends on the first three letters of your receipt number. There are two tiers.
Cases with a receipt number that starts with IOE get full online access. USCIS scans many mailed cases into its electronic system and gives them an IOE number, and those behave online just like a case you filed online. Most marriage green card packets mailed today (the petition and the green card application sent together) get IOE numbers, so many readers land in this tier.
Cases with a receipt number that starts with LIN, ESC, MSC, SRC, WAC, or YSC are the older service-center style. You can still add these to your account, but you get status information only. You can't use the online account to send documents or answer USCIS on these cases.
| What you can do | IOE case (full access) | Service-center case (status only) |
|---|---|---|
| See current case status | Yes | Yes |
| See case history (recent actions) | Yes | Yes |
| Get automatic email and text alerts | Yes | Yes |
| View official notices and letters online | Yes | No |
| Upload documents to the case | Yes | No |
| Respond to a Request for Evidence online | Yes | No |
| Send USCIS a secure message | Yes | No |
| Update your address in the account | Yes | No |
If your case is in the status-only tier and USCIS asks you for more documents (a Request for Evidence, or "RFE"), you respond by mail the old way, following the instructions on the notice. The online account won't let you upload the response. For more on that, see how to fix a mistake after filing.
How to tell which tier you're in
Read the first three letters of your receipt number. That's the whole test. IOE means full access. LIN, ESC, MSC, SRC, WAC, or YSC means status only. You don't have to guess or call anyone; it's printed on the receipt notice you already have.
There's no way to convert a status-only case into a full-access one. The prefix is assigned by USCIS based on how it processes your case, and it doesn't change because you added the case to your account.
If you never got your Online Access Code, lost it, or it expired
Plenty of people hit this. The Online Access Code letter can be slow to arrive, can get lost in the mail, or can expire before you use it. Here's how to handle each version.
It's been a few weeks and no code has arrived. USCIS mails the Account Access Notice separately from your receipt notice, and it often lags behind. Give it time after you file before assuming it's lost. Many filers wait until roughly eight weeks after filing before treating the code as missing.
Your code expired. The Online Access Code is only good for 90 days. If more than 90 days have passed, it won't work, and you request a fresh one from the USCIS technical-support page.
To request a new code, you have two options:
- Online, no phone call: go to my.uscis.gov/account/v1/needhelp, fill out the short Need Help form, and ask for a new Online Access Code. USCIS's technical team emails the new code, usually within a week or two.
- By phone: call the USCIS Contact Center at 800-375-5283 (TTY 800-767-1833), open Monday through Friday, 8am to 8pm Eastern. Have your receipt notice and a copy of your application handy before you call.
If a lawyer or filing service submitted your case
Your Online Access Code may have been mailed to them, not to you. If you used a lawyer or a third-party company and your code never showed up, check with them first before spending hours with USCIS.
One piece of forum advice to ignore: some posts tell you to contact the National Visa Center for your access code. The National Visa Center handles cases going through a U.S. embassy abroad, not USCIS online-account codes for a case you filed inside the U.S. Calling them for an access code won't help.
You don't always need an account: the free case-status tool
If all you want is to check where your case stands, you don't need an account or an access code at all. USCIS runs a free public tool, Case Status Online, at egov.uscis.gov. Type in your receipt number and it shows that one case's current status and the date it last updated. No login, no code, nothing mailed.
A full myUSCIS account is worth the extra setup when you want more than a one-line status:
- One dashboard for every case in your household, instead of checking each receipt number separately.
- Automatic email and text alerts the moment a status changes, so you're not checking by hand.
- A running case history of the recent actions on your case.
- For IOE cases, the ability to see notices and send documents.
So: use the free tool for a quick status check. Link your paper case to an account when you want alerts, history, and (for IOE cases) the ability to act on your case online.
Common reasons a paper case won't link (and what to do)
Even with the right code, some cases refuse to attach. The usual causes:
The code went to your representative
If a lawyer or filing company is on your case, USCIS may send the access code to them. Ask them for it before assuming it never came.
Your account and your case are on different profiles
If you created a second online account (a different email) after filing, USCIS can't always merge a case into an account it wasn't originally tied to. When that happens, you may need to use the specific account the case is associated with, rather than forcing it into another one.
The notice genuinely never arrived
Mail gets lost. Request a replacement code through the Need Help form or the Contact Center, as above.
You're trying too early
The case has to be in USCIS's system first. If USCIS hasn't finished taking in your packet, there's nothing to link yet.

Where Green Card Genius fits
Green Card Genius is self-help software for marriage-based green cards. It walks you through plain-English questions, fills in your USCIS forms based on your answers, and builds your packet for you to review, sign, and file yourself. Tracking your case online afterward is a free USCIS feature, and this guide is here so you can use it without paying anyone.
Because you file your own packet under your own name and email, your Online Access Code comes straight to you, not to a middleman. That sidesteps the single most common reason people lose track of their access code.
Green Card Genius is not a law firm and does not provide legal advice. For a case with legal complications, an immigration attorney is the right call.
Frequently asked questions
Are paper-filed cases automatically added to my USCIS online account?
No. Only cases you file online are linked automatically. If you mailed your forms, your case doesn't appear in an online account until you add it yourself with your receipt number, your Online Access Code, and your date of birth.
Where is my USCIS Online Access Code?
It's printed on a letter USCIS mails you called the Online Account Access Notice. That's a separate mailing from your receipt notice (Form I-797C). The code is 14 characters. If you never received the Access Notice, you can request a replacement code online or by phone.
Is the Online Access Code on my I-797C receipt notice?
No. Your receipt notice shows your receipt number, which you also need. The Online Access Code comes on its own letter, the Account Access Notice. Don't expect to find the code on the receipt notice.
How long is the Online Access Code valid?
90 days. If more than 90 days have passed since USCIS issued it, the code won't work and you have to request a new one at my.uscis.gov/account/v1/needhelp or by calling the USCIS Contact Center.
I never got my access code. How do I request one?
Two ways. Use the Need Help form at my.uscis.gov/account/v1/needhelp and ask for a new Online Access Code, which USCIS usually emails within a week or two. Or call the USCIS Contact Center at 800-375-5283. If a lawyer or filing service submitted your case, check with them first, because the code may have gone to them.
Can I upload evidence online for a paper-filed case?
It depends on your receipt number. If it starts with IOE, yes, you can upload documents and respond to a Request for Evidence online. If it starts with LIN, ESC, MSC, SRC, WAC, or YSC, no, you get status updates only and respond to USCIS by mail.
Can I check my case status without an account?
Yes. USCIS's free Case Status Online tool at egov.uscis.gov shows one case's status from the receipt number alone, with no account and no access code. You only need an account and an access code for alerts, case history, and (for IOE cases) acting on the case.
Why won't my case attach to my account even though I have the code?
The most common cause is that your case is tied to a different online account than the one you're signed in to, and USCIS can't always merge cases across accounts. If that happens, use the account the case is associated with. Other causes: the case hasn't fully entered USCIS's system yet, or the code has expired.
