With over 400 banks participating and billions of transactions being processed every month, UPI has grown even bigger and more effective than incumbent international payment systems.
Its foray abroad began when NPCI International Payments Limited (NIPL), a joint venture of NPCI, began connecting with international fintech platforms and financial institutions. Its objective was to enable UPI-based cross-border payments to foreign merchants and transfer money from India to overseas on the back of India's indigenous digital economy.

Nations that have implemented or harmonized with UPI can become more connected with one of the largest digital economies in the world.
UPI’s global network is expanding rapidly, with several countries entering partnerships to enable Indian travelers and expatriates to make payments using their existing UPI-linked applications.
Singapore was among the earliest adopters, establishing a linkage between India’s UPI and Singapore’s PayNow system. This integration allows instant fund transfers between users in both countries, marking a milestone in cross-border payment interoperability.
Among the Middle Eastern countries, some of the key locations to witness UPI transactions include the United Arab Emirates (UAE). There are a number of Abu Dhabi and Dubai consumer retail and hospitality firms that now adopt UPI payments by joining hands with local payment processors and banks. Onboarding is beneficial for the huge Indian diaspora and the stable count of Indian tourists.
Nepal has also been assigned as the first neighboring country to adopt UPI for transactions at home, enabling the country's traders to get cash payments directly from Indian travelers. It is a milestone towards South Asian regional financial integration.
Bhutan has also followed and become the second to join by adopting UPI with Royal Monetary Authority to facilitate tourism and business.
In Europe, NPCI is collaborating with France for Lyra Network to enable UPI payments in retail and tourism spots. Indian tourists would find the project beneficial where they would consider it convenient to make payments through QR as compared to using currency exchange or cards.
Oman and Sri Lanka have also partnered with NPCI International to explore UPI integration, signaling the next wave of adoption across the Gulf and South Asian regions. Australia and the United Kingdom are in advanced discussions to introduce UPI compatibility for merchants and payment terminals.
There are a number of factors that account for the popularity of UPI globally. Its open architecture is easy to integrate with existing payment networks, which helps it be interoperable with heterogeneous financial environments. Foreign interest among payment merchants and financial institutions is attracted by its cost-effective model of transaction and real-time processing advantage.
It is India's diplomacy and economic activities that propel adoption. Synchronized agreements with finance regulators and central banks of the partner countries have cooperation of regulation and trust in data confidentiality and compliance.
Apart from that, growing Indians outbound tourism of over 30 million travelers every year to 2026 has encouraged foreign consumers to utilize IRCTC UPI. It is a proof of the international influence of Indian consumers and convenience of instant QR payments compared to the traditional ones.
For tourists from India, the ease of using UPI to pay internationally becomes convenient and less cash or credit dependent. Payment through basic interfaces such as PhonePe, Paytm, or Google Pay becomes a breeze without foreign transactions or currency exchange fees.
For Indian companies in partner countries, UPI payments unlock wide and growing volumes of Indian consumers. Small traders are particularly benefited by one-day settlement and reduced costs versus current card-based channels.
The cross-border link of UPI to international payment networks also enables simpler remittances by Indian expatriate professionals, further improving financial inclusion and liquidity in the areas.
UPI’s global expansion represents a landmark achievement in digital finance, symbolizing India’s growing influence on the world’s payment ecosystem. The platform’s success in Singapore, UAE, Nepal, France, and other countries underscores its adaptability and reliability. By bridging cross-border financial systems, UPI is not only simplifying global transactions but also creating a foundation for an interconnected digital economy.
