The Unified Payments Interface (UPI) has become the backbone of India’s digital payment ecosystem. Developed by the National Payments Corporation of India (NPCI) and regulated by the Reserve Bank of India (RBI), UPI allows instant bank-to-bank transfers using a mobile phone.
In just a few years, UPI has transformed the way Indians send and receive money. According to NPCI data, UPI processes more than 10–13 billion transactions every month, making it one of the largest real-time retail payment systems in the world.
Instead of entering bank account numbers and IFSC codes, UPI enables payments using a simple identifier called a UPI ID.
What Is a UPI ID?
A UPI ID, also known as a Virtual Payment Address (VPA), is a unique identifier used to send or receive money through UPI.
The term UPI ID stands for “Unified Payments Interface Identifier.”
It works similarly to an email address but is used for financial transactions.
Example of UPI IDs
- yourname@oksbi
- mobilenumber@upi
- username@paytm
- 9876543210@ybl
Typical UPI ID Format
Most UPI IDs follow this structure:
username@bankhandle
or
mobilenumber@bankhandle
Here,
- username or mobile number identifies the user
- bank handle represents the payment service provider or bank
How a UPI ID Works (Payment Flow)
A UPI transaction follows a simple process.
Step-by-step UPI payment flow
- The sender enters the receiver’s UPI ID.
- The app fetches and displays the receiver’s registered name.
- The sender enters the payment amount.
- The sender confirms the transaction.
- The sender authorises payment using a UPI PIN.
- The payment is processed instantly between bank accounts.
The entire process usually takes just a few seconds.
UPI QR Codes and Payments
UPI IDs can also be converted into QR codes, allowing users to receive payments by scanning instead of typing the ID manually.
For example, a street vendor or small merchant may display a printed QR code linked to their UPI ID. Customers simply scan the code through any UPI app and complete the payment.
QR-based payments are popular because they:
- eliminate manual typing errors
- support payments across different apps
- reduce the need for point-of-sale machines
This is why UPI QR codes are widely used by small businesses, shops and street vendors across India.
UPI Transaction Limits in India
UPI transactions have limits defined by NPCI guidelines and bank policies.
Standard UPI transaction limits
| Type of Limit | Amount |
|---|
| Per transaction limit | ₹1 lakh |
| Daily transaction limit | Usually ₹1 lakh (bank dependent) |
| Number of transactions | Bank-specific |
These limits are set according to guidelines issued by the National Payments Corporation of India.
Higher Limits for Special Transactions

| Transaction Category | Typical Limit |
|---|
| Capital market transactions (IPO applications, broker platforms) | Up to ₹5 lakh |
| Insurance payments | Up to ₹2 lakh |
| Tax payments | Up to ₹5 lakh |
These limits may vary depending on the bank and the payment app.
