Retrieve Lost Aadhaar Number & Forgotten EID / UID


If you misplace your Aadhaar Enrollment ID (EID) or Aadhaar number/ Unique Identification Number (UID), you can swiftly restore access through the official UIDAI website. The Aadhaar card, issued by UIDAI, is a vital identity document in India, serving as proof of identity. It's conveniently accessible electronically via UIDAI's official website.

UIDAI offers a service for retrieving lost or forgotten UID/EID through Permanent Enrolment Centers or Aadhaar Seva Kendras, or conveniently online through the m-Aadhaar app and myAadhaar portal.


Aadhaar cards must be linked to the cardholder's mobile number and remain valid for life. As people may misplace their cards or forget their UID/EID, having an active mobile number linked to your Aadhaar will make the retrieval process easier.
