Wrong PayNow transfer: how recovery actually works

Short answer: Call your own bank immediately and open an erroneous transaction case. Don't WhatsApp the stranger asking for your money back. If you're on the receiving end of someone else's mistake, let the banks reverse it and never PayNow a stranger "back" yourself. Recovery is a MAS process duty, not a same-day guarantee.

The weekly "I PayNow'd the wrong number" post on r/askSingapore always plays out the same way. There's one correct first move, and there's one instinct that feels helpful and ends up costing you twice.

What "erroneous transaction" actually means

Section 6 of the MAS E-Payments User Protection Guidelines (EUPG) covers exactly this: money leaving a protected account and landing with the wrong recipient. It applies to PayNow and FAST-style transfers, which is not the same machinery as a card dispute, so don't expect the chargeback process you know from home. Once you notify your financial institution and it notifies the recipient's, both are expected to make reasonable efforts to recover the sum.

Read that phrasing carefully. It's a duty to try, not a promise to succeed. If the person at the other end simply refuses, the banks escalate rather than force a clawback, and that's where a police report starts to matter.

If you sent the money

Screenshot the transfer first: the proxy you keyed, the name that came back, the amount, the time, the reference. Then call your own bank's hotline, using the number on your card or inside the app rather than one from a search result. Fake hotline listings are a live problem, and you're in exactly the panicked state they're written for.

Ask for an erroneous or mistaken transfer recovery under the EUPG process, in roughly those words. Staff field a lot of vague "wrong transfer" calls, and naming the process puts you in the right queue. Give them the amount, the date and time, the recipient proxy, your own account details. Then the bank-to-bank contact happens without you, and waiting is the hard part. Weeks are normal when the other side is slow to reply. If the recipient ignores their bank entirely, follow your bank's advice on filing a police report. It supports the escalation; it doesn't replace the bank case, so open that first.

Two things not to do while the case is live. Don't fire off a second, correct transfer before the first one is logged, because you'll blur the record of what went where. And don't pay anyone a fee to chase the money for you: nobody legitimate charges for this, and the people offering are running the next scam.

If you received the money

Tell your own bank that an unexpected PayNow has landed. If a stranger messages you claiming it was theirs, tell them to go through their own bank and leave the conversation there. When your bank asks you to consent to the reversal — by letter, at a branch, or on a recorded call — give it, and the money goes back the clean way.

What you shouldn't do is send it back yourself. It feels like the decent thing, which is exactly why it works as a trap: you have no way of knowing the person messaging you is the person whose money it was, and an obliging manual transfer to a stranger is how impersonation and money-laundering setups get their first real transaction. Forum consensus and the banks' own letters agree here, which doesn't happen often enough to ignore.

Habits that stop it happening again

Setting PayNow up needs a local bank account first, and it's worth registering the FIN proxy rather than your mobile number. Prepaid numbers here have a history, and the previous owner's PayNow link isn't always gone by the time the SIM reaches you. We've covered the mechanics in PayNow setup, where it sits in the wider app stack in apps that matter, and the account underneath it in opening a bank account.
