India will see an amendment in processing the Unified Payments Interface (UPI) transactions made through the National Payments Corporation of India (NPCI). There are no transactions for UPI by February 1st, 2025 that will comprise a special character UPI Transaction IDs. As an effort in ensuring technical specifications rolled out at first in March of 2024, it streamlines a particular transaction. Hence, following a standardized procedure and protocol related to UPI enhances security measures against errors and non-compliances.

NPCI Guidelines for UPI Transaction IDs
On January 9, 2025, the National Payments Corporation of India issued a circular requiring all banks, third-party payment applications, and service providers to follow specific guidelines on UPI transaction IDs. These guidelines will standardize the processing of transactions and enhance security in the UPI ecosystem.
As per the circular, special characters like $, #, @, and % are strictly prohibited in UPI transaction IDs. The transaction ID should be an alphanumeric character. If any transaction ID contains special characters, then it will automatically be rejected by the central system to ensure uniformity and prevent errors in processing.
Additionally, NPCI has specified that all UPI transaction IDs have to be unique and exactly 35 characters long to align with technical requirements. This ensures consistency across platforms and minimizes discrepancies in transaction identification.
To maintain efficiency within the UPI framework, NPCI has also mandated that UPI IDs that remain inactive for over a year will be deactivated. This is to prevent the accumulation of unused IDs, thus optimizing system performance.
NPCI had communicated that these rules need to be strictly followed and, failure to abide by them might lead to transaction failure. By enforcing such rules, NPCI wants to make the transactions reliable and ensure interoperability between various UPIs.
Impact on UPI Users
The new rules in UPI transaction ID will be directly felt by the users. If a user tries to perform a transaction, and the ID generated by the UPI application contains a special character, then the transaction would be declined. This might cause payment failures, and for many users who do not know the changes, this could become very inconvenient. Digital payment providers would also be forced to upgrade their systems so that transactions can go through without issues and are secured.
How Users Can Avoid Payment Failures
To prevent disruptions in their digital payments, users are advised to take the following steps:
Ensure that the UPI app is updated to the latest version. Developers are expected to modify their apps to comply with the new NPCI rules.
Only download UPI apps from official platforms like Google Play Store and Apple App Store. Apps from third-party sources may not receive timely updates, leading to transaction issues.
Before initiating transactions, users should ensure that their UPI ID follows NPCI’s new alphanumeric-only rule.
Users should keep track of their transaction history and immediately report any issues to their bank or payment service provider.
Since inactive UPI IDs will be deactivated, users should periodically use their UPI accounts to keep them active.
NPCI’s Additional UPI Requirements
The National Payments Corporation of India has implemented further requirements to make UPI payments more secure, efficient, and convenient. Among these, one major requirement is the use of unique 35-character transaction IDs. So, each transaction will then carry a distinct ID number, avoiding duplication and aiding in its traceability.
It deactivated inactive UPI IDs. Another important change would be the periodical verification of active UPI IDs and regular maintenance of their status by all payment apps including Google Pay and PhonePe. A UPI ID, after a year from its inactivation, would become automatically deactivated; this move seeks to clean the UPI ecosystem and prevent the unnecessary clutter caused by the activation of UPI IDs.
The Reserve Bank of India (RBI) has also increased the UPI transaction limit for payments related to hospitals and educational institutions. It has increased the cap from ₹1 lakh to ₹5 lakh. This will be particularly helpful for those making large payments, like tuition fees or medical expenses, as transactions will be smooth and hassle-free.
These updates collectively reinforce NPCI’s commitment to making digital payments more reliable, secure, and user-friendly for everyone.
Google India and NPCI International MoU
In a bid to expand UPI beyond India, Google India Digital Services and NPCI International Payments Limited (NIPL) have entered into a Memorandum of Understanding. This partnership will facilitate the adoption of UPI globally and simplify cross-border payments, enhancing financial inclusion and digital transformation across the globe.
Key Objectives of the MoU:
Expanding UPI for Travelers: The initiative will enable Indian travelers to use UPI abroad, making payments more seamless and eliminating the need for forex cards or foreign currency.
Implementing UPI in Other Countries: Google and NPCI will collaborate to establish UPI-like digital payment systems in international markets.
Simplifying Cross-Border Remittances: The partnership will focus on making remittance transactions easier by leveraging the UPI infrastructure.
Current Global Presence of UPI
UPI is currently available in over ten countries, including:
Australia
Bhutan
France
Nepal
Oman
Saudi Arabia
Singapore
Sri Lanka
UAE
This MoU is likely to encourage more countries to implement their own UPI-like payment services, thus opening up the door for Indian tourists and foreign vendors. The further internationalization of UPI is likely to drive digital payments in addition to giving India a boost in the domain of fintech innovation.
The Future of UPI in India
These changes introduced by NPCI mark a radical change in the digital payments landscape of India. The limiting of special characters in UPI transaction IDs is one step forward in terms of the standardization of transactions and security. Moreover, the taking of NPCI as a partner by Google to globally propagate UPI will unlock international digital payment opportunities.
What This Means for Businesses
For businesses that operate on UPI transactions, the new regulations carry significant implications. Businesses need to update their payment systems to adhere to the latest specifications of NPCI, which include unique 35-character transaction IDs and the deactivation of inactive UPI IDs. Further, it becomes essential to inform customers about the changes to avoid confusion or declined transactions. Notifying the users of the new limits for large payments in education and healthcare will prevent any hindrances in the seamless payment experience. Finally, business houses should actively monitor the transaction success rates for early detection of compliance issues, which they could then rectify in time. Proactive approach by business houses will enable the continued provision of efficient and secure digital payment to their customers.
What This Means for Users
Users must realize the impact on their daily transactions and be proactive in avoiding such disruptions. Updating their UPI applications to meet new guidelines and understanding broader implications of these reforms will help the adaptation to India's changing digital payment ecosystem.
As these changes take effect, users and businesses have to keep themselves informed and proactive. As NPCI continues to fine-tune UPI, the approach will make digital payments more secure, efficient, and widely accepted. Digital payment infrastructure will become more streamlined and integrated across the globe with these new guidelines.
Stay tuned for more updates as NPCI continues to refine and expand UPI to meet growing demands in India and beyond.
