Start with a correction, because almost every Vietnamese guide still gets this wrong. The national scam reporting address that has been printed everywhere since 2023, on the old cyberspace portal, no longer exists — the domain resolves to nothing at all. Reports sent there go nowhere. The national cyber security centre’s current reporting portal is at canhbao.ncsc.gov.vn.
The bank first, because nothing else holds the money
Call your bank’s hotline the moment you realise, and go to the police the same day. Vietnam has no consumer reimbursement rule for scam transfers — none of the 2024 and 2025 reforms create a right to a refund — so everything depends on reaching the money before it is withdrawn or moved on. That window is hours.
What those reforms did do is make transfers traceable. Since 1 July 2024, any transfer above ten million dong needs a face check against your chip ID or VNeID data, and once your transfers pass twenty million in a day, every further transfer that day needs one however small. That is identification, not insurance: it helps investigators name the account holder afterwards. Statements that victims “can get their money back” because of it are describing traceability, not a refund.
The police report is the only route that can investigate
File a written report — đơn trình báo or đơn tố giác tội phạm — at your ward or commune police station, in person. There is no online consumer intake for this. Bring your chip ID card, the sending and receiving account numbers and names, the amounts and exact times, the bank names, and screenshots of the whole conversation, which in most cases means Zalo or Messenger.
156, for the calls and the texts
The national spam and scam line is 156, free to call, and it also takes structured SMS reports. The syntax matters: for a spam SMS send S (number) (description), for a nuisance call V (number) (description), and for a scam call LD (number) (description). Telecoms operators act on these — a reported number gets forced re-verification, then one-way suspension, then two-way, then termination. It can kill a number. It cannot recover a dong.
The check almost nobody uses
You can text a domain name to 156 and be told whether it is a genuine registered site. It is free, it takes seconds, and it is a distinctly Vietnamese tool that barely anyone uses. Do it before entering anything on a site that arrived in a message.
One thing that is not a scam checker, despite its name: the trusted-network directory is an opt-in certification list that organisations apply to join. A site being absent from it means nothing at all.
The reporting portal is a warning system, not a case system
Be clear about what the national portal does. It aggregates warnings. It does not open a case for you, does not give you a case number, and does not recover money. Report there so that others are warned, and go to the police for your own case.
The scam that comes second, wearing a badge
The cyber security centre has itself published a warning about a site impersonating it and advertising “help getting your scammed money back, 99.9% success”. This is the most reliable pattern there is: the recovery service that finds you after you have been scammed is the second scam, and it will wear the branding of the police or of the agency you just reported to.
The other pattern to know: a caller claiming to be the police or a traffic inspector persuades you to install an app or open a link, takes control of the phone, and empties the account from your own device. No Vietnamese agency asks you to install anything to resolve a case.
And the site
If the scam ran through a website, the company hosting it and the registrar that sold the domain can take it down, usually within hours of a clear report with the exact address and a screenshot. That is quicker than any official channel, in Vietnam as everywhere else.
