Can I set a 5-digit PIN?

No. Indian ATMs accept only 4-digit PIN. Some international cards support 6-digit, but when you use them here machine pads with leading zeros—can fail. Stick to 4-digit numeric PIN; do not use birth-year for safety.

When I first got my debit card, I remember feeling unsure about setting up the right PIN — was it supposed to be 4 digits or more? It’s a small detail, but one that’s crucial for both convenience and security.

How Many Digits Are There in a Debit Card PIN?

A debit card PIN in India typically consists of 4 digits, though some banks may allow a 6-digit PIN for added security. This PIN (Personal Identification Number) acts as your confidential password to authorize transactions at ATMs, POS machines, or online payments.

Why the 4- or 6-Digit Format?

  • 4-digit PINs are standard across most banks and ATMs in India — simple, quick to remember, and universally accepted.

  • Some banks have upgraded to 6-digit PINs to strengthen security, as more digits reduce the chances of guessing or fraud.

Regardless of the length, your PIN should always be unique and not easily predictable (avoid birthdays or repetitive numbers).
