Finding your US visa number shouldn't require a scavenger hunt, but the physical visa foil contains a maze of numbers that often look identical at a glance. Applicants frequently mix it up with passport numbers, control codes, or application IDs. The visa number is an eight-character identifier printed in red ink, typically located in the bottom-right corner of the visa sticker inside your passport. It is unique to that specific visa stamp rather than to you as an individual.
Understanding how to locate and read this code prevents common errors on government forms, employment paperwork, and travel documents. This guide breaks down exactly where the number lives, how it differs from other passport identifiers, and why it matters for your travel.
What is a US Visa Number?
A US visa number—often referred to as a visa foil number—is a unique serial code assigned to the physical foil sticker placed inside your passport by a US embassy or consulate. Think of it as a tracking identifier for that specific sticker.
It doesn't change if you renew your passport booklet, provided your underlying visa remains valid and you travel with both your old and new passports. However, if you apply for a brand-new visa, you receive a new visa stamp and a completely new visa number.
The standard format is straightforward:
- Length: Exactly eight characters on modern visa foils.
- Color: Printed entirely in red ink, which distinguishes it from the black text surrounding it.
- Composition: Most modern numbers consist of eight digits, though older or specific regional formats may begin with a single letter followed by seven numbers.
Exactly Where to Find Your Visa Number
Open your passport to the page featuring the US visa foil sticker. Ignore the large blocks of text in the center and the machine-readable text running along the very bottom.
Scan your eyes directly to the lower-right corner of the sticker. You will see a string of characters printed in a distinct red hue. That red code is your visa number.
If you hold a Border Crossing Card (DSP-150) rather than a traditional passport sticker, the layout differs. On these cards, the identifying document number is positioned on the front of the card, but standard international travelers will find it exclusively on the paper visa foil.
Visa Number vs. Other Passport Numbers
The primary reason people input the wrong number on immigration or employment forms is confusion over the various identifiers printed on the same page. The visa foil contains several numbers that serve entirely different functions.
Passport Number
Your passport number identifies your physical passport booklet, not your visa. It is usually printed in black ink on the left side of the visa foil or on your passport's main biographical data page. Entering your passport number when a form specifically asks for your visa number is a critical error that can trigger processing delays.
Control Number
The control number is an 11-digit code printed in black ink on the visa foil. It acts as an internal tracking code assigned by the Consular Electronic Application Center (CEAC) to monitor your DS-160 application. It is not the number requested by most forms requiring a visa document number.
DS-160 Application ID
Your DS-160 confirmation number is generated when you first submit your online nonimmigrant visa application. It typically starts with letters like "AA" and is used to schedule your interview. This number does not appear anywhere on your visa foil. Once your visa is approved and issued, forms no longer look for your DS-160 ID.
I-94 Admission Number
Your Form I-94 record tracks your lawful arrival and departure history in the United States. It is generated by Customs and Border Protection (CBP) when you enter the country and does not appear on your visa sticker at all. You can retrieve your official I-94 record directly from the CBP I-94 Website.
When and Why You Need Your Visa Number
You don't need your visa number for everyday tasks, but specific administrative scenarios require it:
- Filing USCIS Petitions: Certain adjustment of status or change of status forms ask for the document number of your last-issued visa.
- Employer Onboarding: Human resources departments processing work-authorized visas (such as H-1B or L-1) may request your visa foil details for internal compliance records.
- Government Background Checks: Security clearances or specific state-issued credentialing processes sometimes require historical visa data.
When completing digital fields, type the eight red characters cleanly without adding spaces or dashes unless the system format explicitly demands punctuation.
Common Mistakes to Avoid
- Relying on black ink: If you are looking at a number printed in black, it is not your visa number. The red color is your primary visual cue.
- Confusing expiration with validity: The expiration date listed on your visa foil dictates the final day you can use that visa to travel to a US port of entry. It does not dictate how long you are legally allowed to stay inside the country once you arrive. Your actual authorized stay is determined by CBP officers at the border and recorded on your I-94.
- Throwing away expired visas: If you renew your passport, keep your old passport if it contains a valid US visa. The visa number remains valid as long as the physical stamp has not expired or been revoked, even if the booklet itself is canceled.

Frequently Asked Questions
What should I do if my visa foil number is smudged or unreadable?
If physical wear makes your red foil number difficult to read, check any high-resolution scans or photographs you took of your passport page immediately after receiving the visa. If no copies exist, check past immigration filings where you may have successfully reported the number.
Is the visa number the same for family members traveling together?
No. Every individual traveler receives a unique visa stamp, even infants and children. Each passport gets its own distinct visa foil with a completely unique red eight-character code.
Does a citizen of a visa-waiver country have a US visa number?
No. Travelers entering under the Visa Waiver Program (ESTA) do not receive a physical visa foil or a visa number because they do not require a traditional visa stamp to board a flight to the United States.
Where can I find official definitions of visa terms?
You can review detailed definitions of consular terms and visa classifications directly through the USCIS Official Website.
