What are Aadhaar UID and EID numbers?

There are two numbers which are associated with Aadhaar. They are UID number and EID number. Let’s understand what these numbers are –

  • UID NumberUID Number stands for Unique Identification number. It is the 12-digit number which is mentioned on the Aadhaar card. This number gives you a unique identity and is used for verification purposes.
  • EID NumberEID number, on the other hand, is the number which you get when you enrol for Aadhaar. The full-form of the EID number is the Enrolment Identification Number. This is a 14-digit number which is printed on the enrolment form which is used to apply for Aadhaar card. Before the UID number is assigned to you, you can use the EID number for checking your Aadhaar application status and also for downloading your Aadhaar card in an electronic format.
