Aadhaar has become an important identity document for people across India. From accessing government services and banking facilities to completing verification processes for various financial and administrative purposes, Aadhaar details are frequently used to establish an individual's identity.

However, mistakes in personal information or changes in circumstances can make it necessary to update Aadhaar details. A spelling error in your name, relocation to a new address, change of mobile number or an incorrect date of birth are some common reasons for requesting an update.

What many Aadhaar holders may not know is that the rules are not the same for every type of demographic information. While certain details can be changed multiple times, UIDAI places limits on updates to some other information.

Here is a detailed look at the rules for changing your name, address, mobile number, date of birth and gender in Aadhaar.

How Many Times Can You Change Your Name in Aadhaar?

If your name has been incorrectly recorded in Aadhaar or you need to update it for a valid reason, UIDAI allows changes subject to prescribed conditions.

Under the standard Aadhaar update rules, a person's name can generally be updated up to two times.

This makes it particularly important to carefully review the spelling and other details before submitting an update request.

If the permitted number of name changes has already been exhausted but another correction becomes necessary, the Aadhaar holder may need to follow UIDAI's exception-handling process. Such cases may require a valid reason along with supporting documents and are subject to approval under the applicable rules.

Is There a Limit on Changing Your Aadhaar Address?

Address updates work differently from name changes.

There is generally no fixed lifetime limit on the number of times an Aadhaar address can be updated. This is useful because people may relocate several times due to employment, education, marriage, property changes or other personal circumstances.

To update the address, however, the Aadhaar holder must follow the applicable verification procedure and provide an acceptable supporting document when required.

Once the request and documents are successfully verified, the revised address can be reflected in Aadhaar records.

How Many Times Can an Aadhaar-Linked Mobile Number Be Changed?

There is also no specified numerical limit on how many times you can update the mobile number linked with Aadhaar.

Therefore, if you stop using your old SIM card, lose access to a number or switch to another mobile connection, you can get the new number registered with Aadhaar.

Keeping the correct mobile number linked to Aadhaar is particularly useful because OTP-based authentication is required for several online Aadhaar services.

Unlike some demographic updates that may be completed online, changing the registered mobile number generally requires the Aadhaar holder to visit an Aadhaar enrolment or update centre and complete the prescribed verification process.

Date of Birth Update Has Stricter Rules

UIDAI has tighter restrictions when it comes to changing the date of birth recorded in Aadhaar.

Under the standard rules, the date of birth can generally be updated only once.

Because of this limitation, Aadhaar holders should be especially careful while submitting a date-of-birth correction. The information entered in the request should match the valid supporting document being provided.

If another change becomes necessary after the permitted update has already been used, it may fall under an exception process and additional verification could be required.

How Often Can Gender Be Updated in Aadhaar?

Gender information is another Aadhaar detail for which the standard update limit is more restrictive.

Generally, an Aadhaar holder is permitted to update gender once under the regular process.

Cases that require another correction after the prescribed limit has been reached may need to be handled through UIDAI's exception mechanism, depending on the circumstances and applicable requirements.

Which Aadhaar Details Can Be Updated Online?

Not every Aadhaar correction can necessarily be completed from home.

UIDAI provides selected Aadhaar services through its online platform, while other demographic and biometric changes require an in-person visit.

Address-related services may be available through the myAadhaar portal, subject to the applicable eligibility, authentication and documentation requirements. Access to online services generally requires OTP authentication through the mobile number registered with Aadhaar.

For changes that require physical verification, Aadhaar holders may need to visit an Aadhaar Seva Kendra or authorised enrolment/update centre.

Check Your Details Carefully Before Submitting a Request

The update limits make it important to verify all information before confirming an Aadhaar correction request.

This is particularly crucial for details such as the name, date of birth and gender because standard update limits apply to them. A simple spelling or data-entry mistake could otherwise create additional complications later.

Before submitting an application, check that your supporting documents contain the correct information and that the details entered in the Aadhaar update request match them.

Why Keeping Aadhaar Information Updated Matters

Incorrect or outdated Aadhaar information can create difficulties when identity verification is required. A mismatch between Aadhaar and other documents may result in additional verification during banking, government service or other official processes.

Keeping your current address and mobile number updated can also make Aadhaar-related services easier to access.

In short, Aadhaar holders generally have greater flexibility when updating their address and mobile number, while name, date of birth and gender updates are subject to prescribed limits.

Since UIDAI can revise procedures, acceptable documents and service options from time to time, users should check the latest instructions on the official myAadhaar or UIDAI platform before submitting an update request.
