Applicants seeking information from the UIDAI may also be required to provide additional validation of identity in certain cases.

Residents seeking details of their enrolments like processing stages, Aadhaar number or dispatch and delivery

The UIDAI portal (uidai.gov.in) provides facility to the taxpayers to easily find Aadhaar number or Aadhaar generation status by furnishing the EID number. Similarly, taxpayers are also allowed to get the electronic version of the Aadhaar letter i.e. E-Aadhaar from the resident portal by furnishing the EID number along with demographic information. If the information is matched with the information available in the UIDAI database, a one-time password (OTP) will be sent to the resident’s mobile number or e-mail address provided by the resident at the time of enrolment. In the case, the resident who has not provided mobile number and/or e-mail address at the time of enrolment or who has changed her/his mobile number, the resident will be required to furnish a mobile number along with name, EID and pin code to get the one-time password (OTP) after verification. The OTP is required to download E-Aadhaar. The resident can also get E-Aadhaar through UIDAI regional offices and contact centres after due verification as per the procedure by the concerned regional offices and contact centres.
