What is customer id in post office passbook?
It works like a master key. Even if you open multiple accounts, such as savings or recurring deposits, they all connect to a single customer ID.
The customer ID is your main number at the post office. It is also called the CIF ID. CIF means Customer Information File.
It is one special number just for you. This number connects all of your accounts together in one place. So if you have a savings account and maybe another plan, the CIF ID links them. This helps the post office see all the accounts belong to you.
You can find this number on the first page of your passbook. It is usually printed near your name and account number. It is very important for things like using internet banking. The post office needs it to know who you are.
Customer ID is a unique number given to every account holder. It helps the post office link all your accounts and services under one identity, making management easier.
This number is necessary for online services. To register on the India Post mobile app or internet banking, you must enter your customer ID.
People often confuse it with account number. Account number changes with each account, but customer ID stays constant for you as a person.
