Raised by: Bank / PSP. Source: NPCI, UPI Error and Response Codes v2.9, section 3.1, codes populated by banks and PSPs.

A response arrived too late. NPCI marks ZL as reserved for future use and gives it no technical or business tag. The switch-level code for a late response is U70.

If you were debited and the payment failed, the money is due back by T+1 for a transfer to a person, or T+5 for a payment to a merchant.

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.
