You need to follow these steps for the purpose of transfer of your current account from one branch to another branch:
You are first required to go to your branch personally where your existing account is. There you would give a request for account transfer.
You are now required to submit a written application for transferring your current account to another branch. You need to mention the name of the branch properly and with due care, where you want to transfer your existing account. Some banks also require the reason for such transfer.
You have to submit KYC documents, in case your bank asks for them, which include copies of PAN Cad, Identity Proof and Address Proof.
The banker will verify all the documents and if everything is complete, it will initiate for transferring your account to the new branch. It usually takes 2 to 3 days' time.
After getting the transfer confirmed from your old branch, you may visit to your new branch for confirmation purpose.
