In India, several major banks use a 12-digit format for their account numbers. These include:
- ICICI Bank
- Axis Bank
- HDFC Bank (some account types)
- IndusInd Bank (certain series)
- RBL Bank
- Equitas Small Finance Bank
While 12 digits is a common length, account number formats vary by institution based on their core banking systems. You can verify your specific account length by checking your passbook, chequebook, or the official mobile banking app of your respective bank.
