A visa control number is the unique identifier the U.S. Department of State prints on every machine-readable visa sticker, generated automatically by consular systems when the visa is produced. Federal regulation requires it as a standard data element on the foil, and it works as an internal tracking code tied to that specific issuance.1eCFR. 22 CFR 41.113 – Procedures in Issuing Visas2U.S. Department of State Foreign Affairs Manual. 9 FAM 403.9 – NIV Issuances Because several numbers sit on the same small sticker, most confusion comes from picking the wrong one for a form.
Where the Control Number Appears on Your Visa
The visa sticker, sometimes called the visa foil, is the printed label glued to a page inside your passport. The control number typically appears near the top of that foil. On an immigrant visa, USCIS refers to the identifier in the top-right corner as the “DOS Case ID,” and it follows a format of three letters followed by nine or ten digits.3U.S. Citizenship and Immigration Services.

Layout varies slightly between visa categories and issuing posts. If you’re not sure which number is which on your foil, USCIS publishes sample images on its immigrant fee payment instructions page that show exactly where the DOS Case ID sits.
How It Differs From the Red Visa Number
The identifier travelers mix up with the control number most often is the visa foil number, also just called the visa number. It’s printed in red ink, sits near the lower-right corner of the sticker, and is typically eight digits long. That red number is what most immigration forms are asking for when a field is labeled “visa number.”
The control number is a separate identifier printed elsewhere on the same sticker. A quick way to tell which one a form wants: check the expected format. A field that accepts eight digits is asking for the red foil number. A field expecting a longer alphanumeric string with letters mixed in is asking for the control number or DOS Case ID.
Which Number CEAC Actually Wants
The Consular Electronic Application Center (CEAC) lets applicants check the status of a pending visa application online. Its status tracker asks for a “Case Number,” not a control number by that label. For immigrant visa cases, the case number follows a format of three letters followed by a string of digits, for example MTL1999626025.4U.S. Department of State Electronic Application Center. CEAC Visa Status Check For nonimmigrant applications, the tracker generally wants the application ID from your DS-160 confirmation page.
Entering the wrong identifier returns a “not found” error, which can be alarming but doesn’t mean your case has a problem. Confirm you’ve selected the correct visa category on the search page and that the number you’ve typed matches the format that category uses.
Paying the USCIS Immigrant Fee
If you received an immigrant visa, USCIS requires you to pay an immigrant fee before traveling to the United States. The payment portal needs two pieces of information from your visa packet: your A-Number (the letter “A” followed by eight or nine digits) and your DOS Case ID. Both appear on the visa stamp and on the paperwork the National Visa Center sent during processing.3U.S. Citizenship and Immigration Services. Immigrant Fee Payment: Tips on Finding Your A-Number and DOS Case ID
One detail rejects a lot of payments. The IV Case Number printed on the visa stamp has two extra digits at the end that the DOS Case ID field does not want. If your stamp shows “ABC1234567801,” enter only “ABC12345678” and drop the final “01.”3U.S. Citizenship and Immigration Services. Immigrant Fee Payment: Tips on Finding Your A-Number and DOS Case ID Trimming those last two digits is usually the fix when the portal keeps rejecting your entry.
If the Number Is Damaged or Illegible
Wear, water damage, or a smudged page can make the numbers on your foil impossible to read. You can’t guess at the missing characters. To replace the visa, the Department of State requires you to apply in person at a U.S. Embassy or Consulate abroad, which means a new application, a new fee, and a new interview.
Before you travel, photograph or photocopy the visa foil page and store the copy separately from the passport. The copy won’t get you through a port of entry, but it preserves the numbers you’ll need for online forms and fee payments while a replacement is being arranged.
