The document number on a Permanent Resident Card (green card) is the 13-digit code printed on the back, usually starting with three letters followed by ten digits.
Is the USCIS number the document number?
No, the USCIS number (Alien Registration Number or A-Number) isn't the document number on a green card. The A-Number is a 9-digit identifier beginning with "A" (e.g., A12345678), while the document number is a 13-digit code on the back of your green card.
Think of the A-Number as your immigration fingerprint—USCIS uses it to track every application you’ve ever filed, from work permits to green cards. Meanwhile, the document number is like your card’s serial number. Swap out your EAD card? Your A-Number stays the same, but your green card gets a fresh document number like LIN0123456789012. Keep these two straight in your records.
What is an immigration document number?
An immigration document number is a unique identifier assigned to visas, green cards, and other travel documents, printed on the document itself.
This isn’t just random gibberish—it’s how immigration officials match your paperwork to your identity. On U.S. visas, you’ll spot it in red at the bottom right corner. A Canadian immigration document, for example, might use a format like F123456789. Don’t confuse it with your passport number or that Alien Registration Number (A-Number) you’ve been carrying around. If you're curious about how these numbers are used in different countries, you might find our guide on finding unique identifiers helpful.
Where is the document number on I-551?
The document number on Form I-551 (green card) is printed on the back, usually on the first line of a 90-character string. On older green cards, it may appear on the front.
Modern green cards—issued since 2010—wear their document number proudly on the back, starting with three letters like LIN, WAC, or SRC followed by ten digits. This isn’t just a random string of characters; it’s your golden ticket for proving who you are and your immigration status. Guard it like you would your Social Security number. If your card looks more like abstract art than a government document, USCIS has visual examples online to help you spot it.

What type of document is a permanent resident card?
A permanent resident card is officially Form I-551, issued by U.S. Citizenship and Immigration Services (USCIS) to individuals granted lawful permanent resident status.

These cards typically last a decade before you need to renew them. Honestly, this is the best way to prove your legal status in the U.S. Want the official USCIS scoop on Form I-551?

Is the document number the same as the visa number?
Yes, the document number is the same as the visa number. On U.S. visas, the visa number is printed in red on the bottom right corner of the document.
This isn’t personal data—it’s just the visa’s unique ID. Think of it as your visa’s license plate. It’s different from your passport number or your Alien Registration Number (A-Number). When you travel to the U.S., officials use this number to match your visa to your identity. A typical visa number might look like ABD123456.
Is the document number the same as the application number?
No, the document number isn’t the same as the application number. The document number is tied to the physical document (like your green card or visa), while the application number tracks your case with USCIS.
Imagine you file Form I-485 to adjust your status. USCIS sends you a receipt notice (Form I-797) with an application number like MSC1234567890. That number changes every time you file something new. Your green card’s document number? That stays put. Keep both numbers safe—you’ll need them for future filings.
Is the USCIS number the same as the green card number?
No, the USCIS number (A-Number) is different from the green card document number. The A-Number is a 9-digit number starting with “A” (e.g., A12345678), whereas the green card document number is 13 digits.
Your A-Number is like your immigration shadow—it follows you through every application you’ve ever filed. The green card document number? That’s specific to the card in your hand. For example, your A-Number might be A12345678, while your document number could be LIN01234567890. Keep them separate in your records.
What is the document number on a Certificate of Naturalization?
The document number on a Certificate of Naturalization is an 8-to-11-digit number found in the top right corner. It’s sometimes called the Certificate Number or Naturalization Number.
This isn’t just any old number—it’s your proof of U.S. citizenship, unique to your Certificate of Naturalization. USCIS uses it to verify your naturalized status. Don’t mix it up with your Alien Registration Number (A-Number) or green card document number. Need a replacement? Use this number on Form N-565. Want to see where it’s located? Check the USCIS guide here.
What is the receipt number on a green card?
The receipt number on a green card is a 13-digit number printed on the back of the card, starting with three letters followed by ten digits. This is the same as your document number.
USCIS uses this number to track your green card application from soup to nuts. It’s not your Alien Registration Number (A-Number) or your visa number. Need to check your case status online?

What is an immigration document?

These documents are your lifeline for traveling, working, or proving you’re legally in the U.S. Common examples include the Permanent Resident Card (Form I-551), Employment Authorization Document (EAD), and Advance Parole Document.

What is the SEVIS ID number on a green card?
The SEVIS ID number on a green card is a unique identifier for students or exchange visitors, typically starting with an "N" followed by nine or eleven digits (e.g., N0001234567).
If you were ever an F, M, or J visa holder, your SEVIS ID was assigned by your school or program sponsor. On a green card, this number might hide in the “Remarks” or “Additional Info” section—but don’t count on it being there. It’s not the same as your green card document number or A-Number. Unsure if your green card has one? Check your original immigration records or ask USCIS. For more on SEVIS and student records, visit the ICE SEVIS page.
How do you read a Permanent Resident Card?
To read a Permanent Resident Card, locate the 13-digit document number on the back, and use the USCIS guide to interpret the other fields. The front includes your photo, name, card number, and expiration date.
Modern green cards have a machine-readable zone (MRZ) at the bottom—just like a passport—containing your document number and other identifiers. USCIS breaks down what each field means here. Older cards might look different, but your document number is still the key to identification. For more tips on handling official documents, see our guide on signing documents electronically.
What does 551 mean?
On a green card or visa, “551” refers to Form I-551, which is the official USCIS form used to issue permanent resident cards.
Form I-551 is the legal term for the green card that grants you permanent resident status. The “551” comes straight from the form number USCIS assigned. You’ll often see “I-551” printed on your green card or in USCIS letters. Spot “I-551” on a visa stamp? That means the visa is tied to your green card status.

Is the VAF number the visa number?
Yes, the VAF number is the same as the visa number. The VAF (Visa Application Form) number is printed in red on the bottom right corner of a U.S. visa.
This number is your visa’s unique ID, used by immigration officials to match the visa to your identity. A typical visa number might look like ABD123456. It’s not your passport number or your Alien Registration Number (A-Number). Applying for a green card? Your visa number will be in your immigration records.

There is no document number on a New York State ID. Instead, New York State IDs use a Driver’s License Number or Non-Driver ID Number, which is a 9-digit alphanumeric code.
New York State IDs don’t have a document number like green cards or visas. Instead, they use a Driver’s License Number or Non-Driver ID Number printed on the front.
