UPI Data Privacy: India's digital payment ecosystem is set for a significant privacy upgrade as the National Payments Corporation of India (NPCI) works with banks and UPI service providers to strengthen user data protection. As part of preparations for implementing the Digital Personal Data Protection (DPDP) Act, several changes are expected in the way UPI platforms handle customer information. The proposed measures include masking mobile numbers, encouraging username-based UPI IDs, and improving privacy during digital transactions.

NPCI Preparing UPI Ecosystem for DPDP Compliance

NPCI has initiated discussions with partner banks and UPI application providers to align the country's digital payments infrastructure with the requirements of the Digital Personal Data Protection (DPDP) Act.

The objective is to improve the protection of users' personal information while clearly defining the responsibilities of banks, payment service providers, and other stakeholders involved in processing digital transactions.

The proposed changes aim to reduce unnecessary exposure of personal data without affecting the speed and convenience of UPI payments.

Why Is UPI Privacy Being Upgraded?

At present, most UPI transactions rely heavily on users' registered mobile numbers for identification and payment verification.

While this system makes digital payments simple and convenient, it also increases the possibility of exposing personal information during transactions.

Privacy experts have long argued that displaying complete mobile numbers can create unnecessary privacy risks, especially during person-to-person transfers and merchant payments. The upcoming changes are intended to minimise such risks while maintaining a seamless payment experience.

Mobile Numbers Will Be Masked

One of the biggest proposed changes involves hiding customers' mobile numbers across UPI platforms.

NPCI has instructed member banks and UPI payment applications to mask mobile numbers on customer-facing interfaces.

Under the proposed privacy measures:

• Only the last four digits of a customer's mobile number will be visible.
• Full mobile numbers will no longer appear during UPI transactions.
• Transaction-related communications will also avoid displaying complete mobile numbers.

This change is expected to reduce the risk of personal information being shared unnecessarily during digital payments.

Banks and UPI Apps Asked to Implement Changes

NPCI has reportedly asked banks and payment service providers to complete the required privacy-related system updates by September 4.

Payment platforms are currently working on software upgrades and backend modifications to ensure compliance with the upcoming requirements.

The implementation timeline may vary across different banks and UPI applications depending on their technical readiness.

QR Code Payments Will Offer Better Privacy

The updated framework is also expected to improve privacy for QR code-based transactions.

Once a payment is completed:

• Customers' mobile numbers should not be visible to merchants or other recipients.
• Sensitive personal information should remain protected throughout the payment process.

These changes are intended to make everyday digital payments more secure without affecting transaction speed or convenience.

Username-Based UPI IDs to Be Encouraged

Another important proposal involves promoting username-based Virtual Payment Addresses (VPAs) instead of mobile number-based UPI IDs.

Rather than using a phone number as the default payment identity, users may be encouraged to create a unique username for receiving and sending payments.

This approach allows customers to make transactions without revealing their registered mobile numbers, thereby improving privacy while maintaining the same payment functionality.

The Option Already Exists for Many Users

Many UPI users already have the option to create a customised username-based UPI ID. However, a large number of customers continue to use mobile number-linked UPI IDs because they are automatically generated during account registration.

NPCI now wants payment applications to promote username-based IDs as the preferred option for new users, helping reduce dependence on phone numbers for digital payments.

Will These Changes Make UPI Completely Private?

Although the proposed measures represent an important step toward better privacy, they do not eliminate all data-sharing requirements within the UPI ecosystem.

Banks, payment service providers, and authorised entities will still need to process certain personal information to complete transactions, comply with financial regulations, prevent fraud, and meet legal obligations.

Masking mobile numbers and encouraging username-based IDs primarily reduce the visibility of personal information to other users and merchants. They do not replace the underlying verification, compliance, or security processes required for digital payments.

What Users Should Do

As these privacy upgrades are introduced, UPI users can further improve their account security by following a few basic practices:

• Create a custom username-based UPI ID if the option is available.
• Never share your UPI PIN with anyone.
• Verify the recipient's details before approving payments.
• Keep your banking and payment apps updated.
• Enable app lock or biometric authentication for additional protection.
• Monitor transaction alerts regularly for any unauthorised activity.

Bottom Line

NPCI's proposed privacy enhancements mark an important step in strengthening India's digital payments ecosystem. By masking mobile numbers, encouraging username-based UPI IDs, and aligning the UPI framework with the Digital Personal Data Protection (DPDP) Act, the new measures aim to improve user privacy while preserving the speed and convenience that have made UPI one of the country's most widely used payment systems.

Although these updates significantly enhance privacy, users should continue following safe digital payment practices to protect their financial information and reduce the risk of fraud.
