If you are a permanent resident of the United States, one of the most important identifiers on your green card is the Green Card Document Number. Whether you are applying for jobs, filing government forms, or renewing your immigration status, this number plays a crucial role in verifying your legal status in the U.S. However, many green card holders are unsure where exactly this number is located and what it looks like.
In this step-by-step guide, we will walk you through everything you need to know about the Green Card Document Number, including where to find it, what it is used for, and how it differs from other important numbers on your green card.
What is the Green Card Document Number?
The Green Card Document Number is a unique 13-character identifier issued by U.S. Citizenship and Immigration Services (USCIS). It is sometimes referred to as the Card Number, USCIS Number, or Receipt Number, but these are technically different from one another.
Typically, the document number begins with three capital letters followed by ten numbers, such as SRC1234567890. This number is assigned to your green card and helps track your specific document in USCIS systems.
Why is the Green Card Number Important?
Your Green Card Document Number is essential for:
- Filing immigration forms such as I-90, I-131, and N-400
- Applying for jobs, as employers may ask for it during I-9 verification
- Traveling in and out of the United States
- Renewing or replacing your green card
- Checking your case status online
- Linking biometric data and security information
Mistaking this number for other identifiers on your card may result in delays or rejections during processing. That’s why it is crucial to know exactly what it is and where to find it.
Where to Find the Green Card Number on Different Card Versions
The location of your document number depends on when your green card was issued. Let’s break it down by card version.
A. For Green Cards Issued After May 2010 (New Version)
If your card was issued after May 11, 2010, the document number is located on the back of the card in the upper-right corner. It is a 13-character code (three letters followed by ten numbers), typically under the title “Card#” or sometimes near the “USCIS#”.
Here’s how to identify it:
- Look at the back of your green card.
- Find the line that starts with “Card#”.
- The next 13 characters are your document number.
B. For Green Cards Issued Between 2004 and May 2010
Green cards issued in this time frame display the document number on the front of the card, typically located at the bottom right. It may appear under labels like “Card#” or “Document Number”.
C. For Older Green Cards (Before 2004)
Older versions of the green card may not display the document number clearly. If you cannot locate it easily, refer to your immigration paperwork or consider applying for a new card.
4. Green Card Number vs. Alien Registration Number (A-Number)
Many people confuse the Green Card Document Number with the Alien Registration Number, also known as the A-Number. However, these are two different identifiers:
| Feature | Green Card Number | Alien Registration Number (A-Number) |
| Format | 13 characters (e.g., SRC1234567890) | 8 or 9 digits (e.g., A012345678) |
| Purpose | Identifies the green card document | Identifies the individual’s immigration file |
| Location | Back or front of the card, depending on issue date | Typically listed under “USCIS#” or “A#” |
The A-Number remains the same throughout your life, while the Green Card Number changes each time a new card is issued.
What to Do If You Cannot Find Your Green Card Number
If you are unable to locate your document number, don’t panic. Here are a few steps you can take:
A. Check All Sides of the Card
Review both the front and back of your green card. If your card was issued after 2010, the number is usually on the back.
B. Look for Other Immigration Documents
If you filed Form I-485, Form I-90, or Form I-131, the Notice of Action (Form I-797) you received may contain your document number.
C. Use the USCIS Online Tools
Visit the USCIS Case Status portal and enter your receipt number. If your card was mailed recently, the document number may also appear in your USCIS account.
D. Contact USCIS
Call the USCIS Contact Center at 1-800-375-5283 or schedule an in-person appointment through InfoPass for additional support.
Frequently Asked Questions (FAQs)
Q1: Is the Green Card Number the same as the Receipt Number?
No. The receipt number tracks your application and starts with three letters like LIN, SRC, or MSC, followed by ten digits. The green card number is tied to the physical card and may differ from your receipt number.
Q2: Can I use the Green Card Number in place of the A-Number?
No. The A-Number is your unique immigration identifier used for most forms. The green card number only identifies your current card.
Q3: Does the Green Card Number change?
Yes. If you renew or replace your green card, the new card will have a different document number. Always update your records with the latest number.
Q4: Is it safe to share my Green Card Document Number?
Only share it with trusted entities, such as employers during Form I-9 verification or U.S. government agencies. Avoid sharing it online or with unknown parties to prevent identity theft.
Final Thoughts
Knowing where to find your Green Card Document Number can save you time, prevent errors on immigration forms, and help you navigate your life as a U.S. permanent resident with confidence. Always keep a secure copy of your green card and important immigration documents, and be aware of what each number represents.
Whether you’re applying for jobs, renewing your card, or updating your records, this 13-character identifier plays a vital role in confirming your lawful status in the United States.
If you’re still unsure or have questions about your specific card version, don’t hesitate to contact USCIS directly or consult with a qualified immigration attorney for personalized assistance.
