Services Provided By UIDAI for Lost Aadhaar ID Retrieval

Aadhaar card holders and applicants need to visit the UIDAI official website to retrieve the lost UID or EID number. The web-based platform is user-friendly, and anyone can easily submit their request for retrieval of Aadhaar details.

But before we discuss in detail the steps to retrieve the UID or EID number, one important factor has to be kept in mind.The lost Aadhaar card or Aadhaar enrolment acknowledgement slip must be linked to the registered mobile number and email address.

These two contact details are necessary because an OTP (One Time Password) will be sent to help retrieve the Aadhaar UID/EID.

On the UIDAI website existing Aadhar cardholders and applicants who have recently enrolled for it can submit their request for lost Aadhaar UID/EID retrieval and also download the duplicate copy of Aadhaar from the portal. One needs to follow these few easy steps to get the lost card number and Enrolment number.

Step 1. At first, the residents are required to log on to the official website of UIDAI where the Aadhaar-issuing authority has made available various online services for the public.

Step 2. Then, they have to click on the 'Retrieve Lost UID/EID' option which will open a new page.

Step 3. On the new page, they have to fill in name, email id, and mobile number as mentioned in the Aadhaar enrolment form and the Aadhaar card.

Step 4. Next, the residents will be required to choose anyone of these two options – a) Retrieve Aadhaar Number (UID) or b) Retrieve Aadhaar Enrolment Number (EID).

Step 5. Click on the 'Send OTP' button. After receiving the OTP, enter the same for verification.

Step 6. After the successful verification of the registered contact details, Aadhar card holders will receive their lost Aadhar UID on either email or mobile number depending on the medium they had chosen in STEP 3.

Step 7. Same way, individuals who have lost their EID number will receive it in the registered contact information.

Now, in case, the Aadhaar card or Enrolment slip is lost and can’t be located then after receiving the UID/EID, residents can use it to download e-copies of the lost documents. For this, they will again be re-directed to a new page where they will have to fill in details like name and postal code of the area where they reside along with the ID numbers. Once again, the cardholders have to click on the 'Get OTP' option. After they receive the OTP, all they have to do is download the e-Aadhaar copy on their computer. To ensure security, the pdf version of the lost ID document is password protected. Earlier the password used to be the UID/EID number holders’ area PIN code. But recently UIDAI has made certain changes. Now, the passcode is a combination of the first four characters of the number holders’ name and the four digits of his/her birth year. For example, if the name of the individual is mentioned as ALKA SHARMA and the year of birth as 1967, then the password would be ALKA1967.
