UPI guides

Short, practical explanations of the parts of UPI that generate the most confusion — written for people trying to get paid, not for payment engineers.

Getting set up

How to create a UPI ID

Where your UPI ID comes from, how to find the one you already have, and how to add a readable custom one for free.

What a UPI ID looks like

The anatomy of name@bank, which characters are allowed, and why the part after the @ is not where your money lives.

QR code for a bank account

Step by step from an account number and IFSC — including why some apps refuse the result.

Getting paid

QR code vs payment link

Which to use where, and why they are the same thing underneath.

UPI transaction limits

The caps that actually apply, why ₹2,000 keeps coming up, and what to do when a payment is blocked.

Get a UPI ID from a QR code

How to read a QR back into a UPI ID, and what that does and does not prove.

Tools

Everything above is explanation. When you want to actually generate something, start with the UPI QR code generator or the payment link generator. Both are free, require no signup, and run entirely in your browser.

If you are trying to work out whether a payment you were shown was real, read fake UPI payment scams first.
