Before you send it
- Go to the branch yourself with your original identity proof. Banks do not change a mobile number on a letter sent through someone else.
- Banks usually have their own one-page form for this. Ask for it; use this letter if they do not.
- After the change, make a small test: check that an SMS alert arrives on the new number.
- Change the number linked to UPI apps too. They do not update by themselves.
What to attach
- Copy of an identity proof (Aadhaar or PAN card), with the original to show
- Passbook
This is a general format, written by us, to save you time. If the bank has its own printed form, use that form. Last checked: 11 November 2026.
