Documents Required for Phone Number Update

[subornaakter40]

While changing the mobile number does not usually require extensive documentation, you may need to submit:

Copy of existing PAN card

Proof of identity (e.g., Aadhaar card, passport, voter ID)

Proof of address, if you're also updating your contact address

Photograph and signature, for individual applicants

If the update is being made on behalf of a minor switzerland mobile phone number list or an organization, supporting authorization documents may be required.

How Long Does It Take to Update the Phone Number?
After successful submission of the application, it typically takes 15–20 working days for the updated PAN card to be delivered and the database to reflect the changes. The OTP verification of the new phone number is usually instant.

Applicants can track the status of their request using the acknowledgment number provided during the application process on either the NSDL or UTIITSL portal.
