UPI error XF: Format error (payer bank)
Raised by: Payer's bank. Source: NPCI, UPI Error and Response Codes v2.9, section 3.1, codes populated by banks and PSPs.
What it means
The payer's bank couldn't read the request because a field was in the wrong format.
No. This decline happens before your account is debited.
Nothing to refund in the normal case. If a debit does show on your statement, the bank must reverse it by T+1 for a transfer to a person, or T+5 for a payment to a merchant.
Payer's bank, about a message from the PSP or switch.
Business: the systems worked and declined the payment.
What you should do
Try again later or use another UPI app. This is a system issue, not something you entered wrong in most cases.
If you are a merchant, bank or PSP
Check the message fields you send against the NPCI API spec. Format errors are integration bugs.

If it still isn't sorted
- Raise a complaint inside your UPI app. Every UPI app has a help or dispute option on the transaction, and it goes into NPCI's online dispute system. Keep the UPI transaction ID or RRN handy.
- If the app doesn't resolve it, contact your bank's grievance desk with the same reference.
- If your bank hasn't replied within 30 days, or you're not happy with the reply, complain to the RBI Ombudsman at cms.rbi.org.in. It's free.
Technical or business decline?
NPCI splits declines into two kinds. A technical decline means a system didn't respond or failed: a bank offline, a timeout, a switch error. A business decline means the systems worked and said no, for a reason about the account or the payment: wrong PIN, not enough money, a limit, a risk check. Retrying helps with some technical declines and almost never with business ones.
