Visa Number: What It Is and Where to Find It

A visa number is a short identifier printed on U.S. immigration documents, and the term actually refers to two different things depending on context: the red 8-digit “visa foil number” printed on a visa stamp in your passport, or the concept of an “immigrant visa number” becoming available under the monthly Visa Bulletin before a green card can be issued. Both matter, and confusing them causes real problems on forms and in case tracking.

Key takeaways

• The visa foil number is a red, typically 8-digit number in the lower right corner of a U.S. visa stamp, distinct from the passport number and the visa’s control number.
• An “immigrant visa number” is a different concept entirely: it refers to visa availability under the annual numerical limits Congress sets, tracked through the Department of State’s monthly Visa Bulletin and your priority date.
• The visa number is not your A-Number, your USCIS receipt number, or your passport number, and mixing these up on a form can cause processing delays.

What is a visa number?

“Visa number” is one of those immigration terms that means something slightly different depending on who is using it and why. In everyday use, when someone asks “where is the visa number on my visa,” they almost always mean the identifying number physically printed on the visa foil, the sticker or stamp a consular officer places in your passport when you are issued a U.S. visa. That number is sometimes called the visa foil number or the visa control number, and it identifies that specific visa document.

In a more technical, immigration-law sense, “visa number” also refers to something else: the numerical slot that must be available before the government can issue certain immigrant visas or approve certain green card applications. Because family-sponsored and employment-based immigrant visas are numerically capped each year, an application cannot move forward to a final grant until a visa number in that category is actually available. We explain both meanings below, because the practical steps you need to take are different for each one.

Where do I find the visa number on my visa?

If you are holding a U.S. visa in your passport and looking for the visa number, look at the visa foil (the stamp or sticker itself), not the passport’s own biographic page. On most current U.S. visas, the visa number:

• Is printed in red ink
• Sits near the lower right corner of the visa foil
• Is typically an 8-digit number
• May be preceded by a single letter on some older visas

This red number is what most immigration forms mean when they ask for your “visa number” or “visa foil number.” It is a different number from the black machine-readable line at the bottom of the visa, different from your passport number (which is printed on your passport’s own data page, not the visa), and different from the visa’s control number, which serves an internal government tracking purpose and is not the same field. If you are filling out a form and it specifically asks for the number “as it appears on your visa,” use the red number from the visa foil exactly as printed.

The State Department is the government agency that issues U.S. visas and maintains guidance on reading visa documents, including where to find fields like the visa number, through its consular affairs resources at travel.state.gov. If your visa was issued as part of an immigrant visa package, USCIS also confirms where these numbers live on the physical document: on the immigrant visa stamp, your Alien Registration Number appears labeled as the “Registration Number,” and your Department of State Case ID appears labeled as the “IV Case Number,” according to USCIS guidance on the Immigrant Fee. That is a useful anchor point because it shows how many different numbers sit on one small document, and how easy it is to grab the wrong one.

What is an immigrant visa number and why does availability matter?

This is the meaning of “visa number” that trips people up most, because it is not printed anywhere. It is a status, not a printed digit string. Congress sets annual limits on how many family-sponsored and employment-based immigrant visas the government can issue. Under the Immigration and Nationality Act, family-sponsored preference visas are generally limited to 226,000 per year and employment-based preference visas to at least 140,000 per year, according to USCIS. Immediate relatives of U.S. citizens (spouses, unmarried children under 21, and parents of adult citizens) are not subject to this cap, so a visa number is always available to them. Everyone else in a preference category has to wait their turn.

Here is how the waiting works in practice. When a qualifying relative or employer files a petition on your behalf, that filing date becomes your priority date, essentially your place in line. Each month, the Department of State publishes the Visa Bulletin, which lists cut-off dates for each preference category and country of chargeability. If your priority date is earlier than the relevant cut-off date, a visa number is considered “available” to you, and you can move forward with the final steps in the process, either an interview abroad or, in the United States, filing an adjustment of status application. If your priority date falls after the cut-off date, you keep waiting until the Visa Bulletin moves in your favor.

USCIS puts it directly: “A visa must be available before you can take one of the final steps in the process of becoming a lawful permanent resident,” and how long that takes “depends on your priority date, preference category, and the country to which the visa will be charged,” per USCIS’s page on visa availability and priority dates. When demand in a category exceeds the annual supply, that category becomes “oversubscribed,” and the Visa Bulletin sets a cut-off date to stay within the statutory limits. Occasionally, dates move backward instead of forward, a situation known as visa retrogression, which happens when more people become eligible in a given month than there are visa numbers left to give out. It generally resolves, at least partially, when a new fiscal year begins on October 1 and a fresh annual supply of numbers opens up.

This is also where the National Visa Center comes in for cases processed abroad: once your priority date is current, NVC assembles your file and schedules your interview at a U.S. embassy or consulate. If you are adjusting status inside the United States instead, USCIS uses the same Visa Bulletin charts, either the Final Action Dates chart or, when USCIS designates it, the Dates for Filing chart, to decide when your Form I-485 can be filed or approved.

Visa number vs. A-Number vs. receipt number: what’s the difference?

We regularly hear these terms used interchangeably, and they should not be. Each one identifies something different:

• Visa number (visa foil number): the red number on your visa stamp, identifying that specific visa document. It does not identify you across your whole immigration history, only that one visa.
• A-Number (Alien Registration Number): a 7, 8, or 9-digit number DHS assigns to identify you personally and the immigration file connected to you, used by USCIS, the immigration courts, and other agencies. The USCIS glossary confirms this definition. Unlike a visa number, your A-Number generally stays the same across your entire immigration history. We cover this identifier in detail in our guide to your USCIS A-Number, including where it appears on a green card and other documents.
• USCIS receipt number: a 13-character code, three letters followed by ten numbers, that USCIS assigns to a specific application or petition when it receives it. You may accumulate several receipt numbers over the years (one per filing) while your A-Number stays constant.
• Passport number: issued by your country of citizenship, printed on your passport’s biographic data page. It has nothing to do with U.S. immigration numbering systems at all; it simply identifies your travel document.

If you eventually receive a green card, that card carries its own additional identifiers as well. We walk through what appears on that document in our guide to Form I-551, the Permanent Resident Card. And if your case involves a work permit in the meantime, our EAD guide explains the separate numbering on that card as well. Keeping these straight matters because government systems are unforgiving about mismatched numbers, and entering the wrong one on a form can trigger a request for evidence or a processing delay that was entirely avoidable.

What if my visa number is unreadable or I need it for a form?

Visa foils fade, get stamped over, or wear down at the edges, especially on older passports or visas that have been through years of travel. If you cannot clearly read the red visa number on your foil, a few options can help:

• Check older paperwork first. If you have a copy of your visa application, an old DS-160 confirmation, or prior travel records, the visa number may be recorded there even if the physical stamp has faded.
• Look at related documents from the same visa issuance. If your visa was tied to an immigrant visa package, your USCIS Immigrant Fee handout or immigrant data summary may also list related numbers, though not necessarily the visa foil number itself.
• Follow the form’s specific instructions. Some USCIS and State Department forms allow you to proceed, or to note the number as unavailable, if the visa number genuinely cannot be read. Do not guess at digits; an incorrect number can cause more delay than an honest note that the field is illegible.
• For a DS-160 online visa application, if you are asked for your previous visa number and your prior visa is expired or worn, use the number from that most recent prior U.S. visa. The number remains valid in the government’s system even after the visa itself has expired, and it helps the consular officer pull up your travel history.

If your situation instead involves travel documents tied to a pending case (for example, advance parole rather than a visa), the numbering and process are different. Our guide to Form I-131 and advance parole covers that separately. And if you are asking about a visa number because you are getting close to becoming a U.S. citizen, our guide on what it means to be a naturalized citizen explains what changes once that final step happens.

Frequently asked questions

Is the visa number the same as the visa control number?
No. On most U.S. visas, the visa number and the control number are different fields. The visa number is the red, typically 8-digit number in the lower right corner; the control number serves a separate internal tracking function on the document. If a form specifically asks for the visa number, use the red number.

Do I need a visa number to apply for a green card?
It depends on which meaning you mean. If a form asks for the physical visa foil number from a visa you previously held, provide that number if you have it. But the more important “number” for a green card application in a capped category is the immigrant visa number described in the Visa Bulletin: your priority date needs to be current before the final steps of your case can move forward. Immediate relatives of U.S. citizens do not face this numerical wait.

How do I know if a visa number is available for my priority date?
Check the current month’s Visa Bulletin from the Department of State, find your preference category and country of chargeability, and compare the listed cut-off date to your priority date (found on your Form I-797 receipt notice). If your priority date is earlier than the cut-off date, or if the chart shows “C” for current, a visa number is generally available to you.

What should I do if I entered the wrong visa number on a form?
If you catch the error before submitting, correct it against the actual visa foil before you file. If you already submitted a form with an incorrect visa number, do not simply resubmit a duplicate application; the right correction path depends on which form, which agency, and where the case currently stands. That is a good moment to talk to an immigration attorney rather than guess.
