Your Princeton PUID is printed on the front of your TigerCard. It is the unique identifier for an individual who has an official affiliation with the University. It is a unique nine digit number and it is not your social security number (SSN). 

Students (and those they designate) will need this number to access their tuition e-bill.

Students are able to see their PUID in TIgerHub.

The PUID is also displayed on the payroll statement.

The PUID is also sometimes referred to as a Student ID or Princeton ID.
