UPI PIN: Meaning, how to generate and change it

Unified Payments Interface (UPI) has transformed digital payments in India, offering seamless transactions at the touch of a button. Central to this system is the UPI PIN, a security feature that ensures safe fund transfers. This Personal Identification Number (PIN) acts as a password for authorising payments and safeguarding sensitive banking details.

Users need to set up a secure UPI PIN when registering for services like Bajaj Pay. Learning how to create, change, and secure this PIN helps users maximise their digital payment experience while staying safe.

What is a UPI PIN

A UPI PIN is a unique numeric code that users must input when making a payment through a UPI-enabled platform. It acts as a security layer to confirm transactions and prevent unauthorised access. When linking a bank account with a UPI app, users are prompted to set up a PIN. Depending on the bank’s policy, it can be either a 4-digit or 6-digit code. Each transaction requires the user to enter the PIN for authentication, ensuring funds are only transferred with their explicit consent.

Unlike an MPIN, which is used for mobile banking login, a UPI PIN is specific to payment approvals. Services such as Bajaj Pay rely on the UPI system to streamline payments across various merchants and utility providers. For added security, users should avoid sharing their PIN with anyone.

Difference between 4-digit and 6-digit UPI PIN

Feature	4-Digit UPI PIN	6-Digit UPI PIN
Security level	Provides basic security	Offers enhanced security
Usage	Supported by some banks and UPI apps	Commonly used by banks for better protection
Complexity	Easier to remember but slightly less secure	More secure but can be harder to recall

Both types of PINs work the same way, but a 6-digit PIN provides stronger security. Users should choose a PIN format supported by their bank and preferred UPI app.
