Friends, as we all know, the Aadhaar card is an essential document for Indians, serving purposes such as opening a bank account, obtaining a SIM card, and securing admission to schools and colleges. Given its significance, it is crucial that the information provided on your Aadhaar card is accurate and up-to-date. Occasionally, individuals may discover errors in their Aadhaar details or find it necessary to update their information due to changes in their personal circumstances. The UIDAI permits the updating of various details on an Aadhaar card. However, many people are unaware that certain specific details can be corrected only once in a lifetime. Let's take a closer look at this:

**Details That Can Be Updated in Aadhaar**

The UIDAI allows Aadhaar holders to update various types of demographic and biometric information whenever necessary. These include:

Name

Address

Date of Birth

Gender

Mobile Number

Biometric details, such as fingerprints, iris scans, and photographs

While most of these details can be updated multiple times—subject to specific conditions—there are strict limitations regarding two crucial details.

**Details That Can Be Changed Only Once**

**1. Date of Birth**

According to UIDAI regulations, the Date of Birth on an Aadhaar card can be updated only once. If your Date of Birth was recorded incorrectly during the initial Aadhaar enrollment process, you are permitted to rectify it only a single time.

To update your Date of Birth, you must submit valid supporting documents, such as a Birth Certificate or any other approved proof of age. Without the appropriate documentation, the UIDAI will not process the request.

**2. Gender**

Another detail that can be updated only once is the gender of the Aadhaar card holder. The UIDAI permits Aadhaar holders to make a change to their gender details only one time. Following this correction, no further changes are generally permitted.
