Confused about all the numbers out there? Let us explain.

The MaineCard system uses several identification numbers for access to different resources/systems. This is necessary to tie all the systems together. Below we have listed the numbers that are used with brief explanations of their use. As always, if you still have questions, contact us by email at

Your MaineCard ISO Number

This number is printed on the front of your card and is 16 digits, starting with “6391 49”.

This number is unique to your card and will change every time you are issued a new card. This number will ensure that when you lose your card, no one else can access your accounts or use your card to access any of our residence halls. This number is also used at the registers across campus if your magnetic stripe is not working.

Library Barcode Number

This number is printed on the back of your card, below the barcode, and starts with “25022”.

This number is ONLY used by the library. The library is part of a statewide system that uses its own identification numbering scheme. You will use this number to access library resources. This number is NOT used anywhere else on campus.

Your Campus ID Number

When MaineCard Services refers to your Campus ID number, we no longer refer to your Social Security Number. Your Campus ID number is the 7 digit ID number assigned to you by the University.

To find out what your Student ID number is, visit the University of Maine “Maine Street” portal. Once you are logged in, use the following navigation to find your Student ID Number:

  • Go to Student Self-Service -> Student Center.
  • Once in Student Center, go to the “Demographic Data” link under the Personal Information bar.
  • The ID is the first thing listed once you click the Demographic link.

MaineCard Services uses your Student ID to allow you to manage your account online. The number to use when accessing the online card office is this seven digit number preceded by “00.” For example if your Student ID is “0012345”, your Campus ID to access the card office would be “000012345” (nine digits in total).
