How to Read a Permanent Resident Card

It’s important to understand all the information included on your permanent residence card. The front of the card is fairly straightforward, with information about your name, country of birth, date of birth, and the card’s expiration date. Other important information on the card includes the following.

  • USCIS#: This describes your alien registration number. All lawful permanent residents have an 8- or 9-digit alien number that is unique to them.
  • Category: This describes the specific immigrant category that USCIS used to admit the immigrant to the United States. Other USCIS documents refer to this field as “class of admission.” It generally includes one or two letters and a number.
  • Resident since: This states the date on which the immigrant was granted permanent residency either at a U.S. embassy or through adjustment of status. This is an important date for those wishing to apply for citizenship through naturalization.

The back of the permanent resident card is a little more complicated and less intuitive. The top left corner has a “Form I-551” label, which is the current USCIS internal form number for the permanent residence document.

The bottom half has three long lines of letters and numbers that have specific meaning. We break down these three lines in the following sections based on the character numbers in order.
