A permanent resident card number is a 13 digit number that is listed on every Green Card. This number is often made up of 3 letters followed by 10 numbers.

Throughout the process of getting a Green Card, the U.S. Citizenship and Imigration Services (USCIS) tracks your case with this number to identify you. Each immigrant who is getting a permanent resident Green Card will be assigned a unique permanent resident card number prior to getting their physical card. 

The permanent resident card number may also be referred to as a Green Card number, Case number, and receipt number.

This number is different from an Alien Registration number.

Where to find the Permanent Resident Card number?

On the back of every Green Card, there is a long string of numbers at the bottom. The permanent resident card number can be found at the end of the first line. It starts with 3 letters and is followed by “<<” at the end, which simply indicates a space holder.

Each number begins with 3 letters that stand for the service center that handled the case. 

Here is a list of the 3 letter codes for each USCIS service center:

  • CSC – California Service Center
  • EAC – Eastern Adjudication Center (now known as Vermont Service Center)
  • IOE – ELIS (efile)
  • LIN – Lincoln Service Center (now known as Nebraska Service Center)
  • MSC – Missouri Service Center (now known as National Benefits Center)
  • NBC – National Benefits Center
  • NSC – Nebraska Service Center
  • SRC – Southern Regional Center (now known as Texas Service Center)
  • TSC – Texas Service Center
  • VSC – Vermont Service Center
  • WAC – Western Adjudication Center (now known as California Service Center)
  • YSC – Potomac Service Center

For example, in the permanent residence card number CSC 17 012 34567, this case was received by the California Service Center.

CSC 17 012 34567

The following 2 digits represent the year that the case was received. Government agencies use a fiscal year that goes from October 1st to September 30th. This means that cases that are received between the months of October and December will not state the actual calendar year the case was received. For example, in the permanent residence card number example bolded above, this case was filed between October 2016 and September 2017.

CSC 17 012 34567

The next 3 numbers represent the work day that the case was opened. For example, in the permanent residence card number example bolded above, this case was opened on the 12th work day of the 2017 fiscal year. 

CSC 17 012 34567

The final 5 numbers represent the case number that is specific to you.
