What Is Your F-1 Visa Number, and How Is It Different From Your SEVIS ID?

Your F-1 visa number and your SEVIS ID look similar but unlock completely different systems — mixing them up on a form can cost you time.

You're staring at a form that asks for your "visa number," and your F-1 visa sticker, your Form I-20, and your I-94 printout each have a different string of digits on them. Which one does the form actually want? Get it wrong on a DS-160 renewal, a background-check form, or an internal HR system, and you'll spend an afternoon untangling a mismatch that never needed to happen.

Your F-1 visa number is the number printed on the actual visa foil, the sticker in your passport, not your SEVIS ID, not your I-94 admission number, and not a USCIS receipt number. All four exist in different systems and get used on different forms. Here's exactly where to find each one and how to keep them straight.

Where your F-1 visa number actually lives

The visa number, also called the control number, is printed directly on the visa stamp a US consulate places in your passport. On most visas issued in recent years it appears in red ink in the lower right corner of the sticker; on older visas the same number sometimes sits in the upper right instead. It's a short, all-numeric string, generally eight digits on current visas, and it's separate from the machine-readable line of letters and numbers running along the bottom of the visa page.

Two things trip people up here:

• It's not your passport number. Your passport number is printed on your passport's photo page by your home country's government and has nothing to do with your US visa.
• It only exists if a visa was actually issued. If your F-1 application was refused, there's no visa number to find, because no visa stamp was ever placed in your passport.

It's also worth separating this from a completely different use of the phrase "visa number." In the green-card world, "visa number" sometimes refers to the availability of immigrant visas under the per-country limits tracked in the monthly Visa Bulletin and discussed alongside priority dates. That's an entirely different concept tied to permanent residence, not to the nonimmigrant visa sticker in your passport. If a form is asking about your F-1 visa specifically, it wants the control number on the sticker, not anything related to green-card visa availability.

What the F-1 visa number is actually used for

In practice, you'll need this number far less often than you'd expect:

• Renewing your visa via the DS-160. The online nonimmigrant visa application asks for your previous visa number when you're applying for a new F-1 stamp after your current one expires or is used up.
• Certain consular or CBP inquiries. Occasionally a consular officer or a Customs and Border Protection agent references it when looking up your travel history, though they can typically pull this from your passport and biographic data alone.
• Almost nothing else. Your school, your employer, USCIS filings, and most background-check or onboarding forms do not use this number. They use the SEVIS ID, your I-94 record, or a document-specific number instead.

If a job application or onboarding form is asking for a "visa number" and you're not sure which one it means, it's worth asking HR to clarify before you guess, since submitting the wrong identifier can trigger a mismatch that delays your start date.

F-1 visa number vs SEVIS ID vs I-94 number vs receipt number

These four numbers get confused constantly because they're all short strings tied to your immigration paperwork, but they track different records issued by different agencies.

Notice the pattern: each number belongs to a different record, not to you as a person. Your visa number belongs to a visa stamp, which can expire and be reissued. Your SEVIS ID belongs to a SEVIS record, which generally stays constant through a continuing program. Your I-94 number belongs to a single admission at the border, and a new one is generated every time you re-enter the country. If you've ever needed to correct a wrong date or classification on that admission record, our walkthrough on fixing I-94 errors covers how that process works.

Why the difference actually matters

The confusion isn't just academic. A few concrete places where mixing these up causes real friction:

1. DS-160 renewal. The form's "previous visa number" field wants the control number off your old visa sticker. Entering your SEVIS ID here is a mismatch a consular officer will need to sort out.
2. OPT and STEM OPT filings. Your Form I-765 application, and everything downstream of it in the SEVIS Portal, is keyed to your SEVIS ID and your I-20, not your visa number. If your employer's HR team asks for a "student visa number" in this context, they usually mean your SEVIS ID.
3. Program changes. A new I-20 issued for a genuinely new academic program, such as starting a master's degree after finishing a bachelor's under a new admission, typically comes with its own new SEVIS ID rather than continuing the old one. This is one more reason your I-20 records matter for tracking your full academic timeline; see our guide on F-1 I-20 recordkeeping and the four-year rule for how that record-keeping connects to your admission end date.
4. Every future visa application. Because DS-160 forms ask about visa history at multiple points in your career, including later transitions to H-1B, knowing where to find each old visa number saves you from digging through old passports at the last minute.

Step by step: locating each number when you actually need it

1. F-1 visa number. Open your passport to the visa page. Look for a short, printed number, often in red, in the lower right or upper right corner of the sticker.
2. SEVIS ID. Pull up your current Form I-20. Look at the top right of the first page for the field labeled "SEVIS ID No." It starts with N followed by 10 digits.
3. I-94 number. Go to CBP's I-94 retrieval site and pull your most recent admission record. If the name, date, or class of admission on it looks wrong, that's a correction issue, not a lookup issue.
4. USCIS receipt number. Check the top left of any I-797 Notice of Action you've received for a petition filed on your behalf, such as an EAD or a change-of-status application. Our guide to reading a USCIS receipt notice and checking case status walks through what each field on that notice means.

Common mistakes

• Entering your SEVIS ID where a form wants your visa number, or vice versa. They're formatted differently on purpose, N-plus-digits versus a short all-numeric string, precisely so they don't get confused with each other on a well-designed form, but people still transpose them.
• Assuming your visa number is permanent. It isn't. Every new visa stamp, including a straightforward renewal, is a new document with its own new number.
• Confusing an expired visa with expired status. Your F-1 visa stamp can expire while you're still inside the US in valid status, since the visa is a travel document that lets you enter the country, not a measure of how long you're authorized to stay once you're here. Whether your underlying status is still valid is a question for your DSO, not something the visa's expiration date answers on its own.
• Mixing up the F-1 visa number with immigrant "visa number" concepts from the green-card process. These share a name but describe entirely different systems.
• Sharing your SEVIS ID with unverified requesters. It ties directly to your immigration record. Treat it the way you'd treat any other identifying document number, and only share it with your school, a verified employer process, or USCIS-related filings.

If you can't locate your visa number

If your visa sticker is damaged, unusually old, or simply doesn't display a clear control number, don't guess a value or leave a required field blank on something like the DS-160. This is a question about a State Department travel document, so the right contact is the consulate or visa application center that issued it, not your school's international office. Your DSO can help you sort out anything tied to your SEVIS record or your I-20, but they don't administer visa stamps, and neither guessing nor an unofficial workaround is worth the risk of an inconsistency showing up later in your travel history. For anything that touches an actual filing decision, whether that's how to answer a DS-160 question or how a visa gap might affect a future petition, loop in your DSO for F-1 and SEVIS questions and a licensed immigration attorney for anything involving a specific filing choice.

Frequently asked questions

Where do I find my F-1 visa number? Your F-1 visa number, sometimes called the control number, is printed on the actual visa stamp inside your passport, usually in red ink. On most visas issued in recent years it sits in the lower right corner of the sticker, and on older visas it can appear in the upper right instead. It is not the same as your passport number, which is printed separately on your passport's photo page.

Is my F-1 visa number the same as my SEVIS ID number? No, they track completely different things. Your F-1 visa number identifies the specific visa stamp in your passport and is issued by a US consulate, while your SEVIS ID identifies your student record inside the Student and Exchange Visitor Information System and is issued by your school through your Form I-20. The SEVIS ID starts with the letter N followed by ten digits and stays tied to your academic record rather than to any single travel document.

What if my F-1 visa does not show a visa number? This is uncommon on standard US visas but can happen with damaged, very old, or unusually printed stamps. Do not guess or leave it blank on a form like the DS-160 without checking first. Contact the consulate or visa application center that issued the visa, since this is a travel document question rather than something your DSO or your school can resolve.

Does my F-1 visa number change every time I renew my visa? Yes. Each new visa stamp you receive, including a renewal after the old one expires, gets its own new visa number because it is a new physical or electronic document. Your SEVIS ID does not change the same way, it generally stays constant for as long as you remain on the same continuing SEVIS record, even as your visa is renewed multiple times.

Do I need my F-1 visa number for OPT, a job application, or Form I-9? Usually not. OPT applications and your I-765 filing rely on your SEVIS ID and your I-20, not your visa number. Form I-9 and most job applications ask for your work authorization document details, such as your EAD number, rather than the number on your visa sticker. Save the visa number for DS-160 renewal applications and situations where a consulate specifically asks for your visa history.

Sorting out which number goes where is a small thing until it holds up a filing you actually need on time. F1Jobs works with F-1 and OPT candidates on the parts of the job search that come after the paperwork is straight.
