What does a USCIS receipt number look like?
Updated · Not legal advice
A USCIS receipt number is a 13-character code: three letters followed by 10 digits, for example IOE0912345678. It is printed on your Form I-797 notices; when you check status online, leave out dashes but keep any asterisks that appear on the notice.

Is it safe to share?
Anyone with your receipt number can see the public status of that case on USCIS's website, but not your file or personal documents. Share it only with services you trust; never share your USCIS account password. See are case tracker apps safe.
Quick answers
- Can someone do anything bad with my USCIS receipt number?
- The receipt number alone shows the public case status. It does not give access to your account or documents. Do not post it publicly next to your name and other details.
- Does an H-1B transfer receipt show up in USCIS case status online?
- Yes. The new employer's Form I-129 gets its own receipt number, which you can check like any other.
- My receipt number says not found. Why?
- Check for typos, leave out dashes, and keep asterisks if printed on the notice. Very new receipts can take a short time to appear.
