I didn’t set out to write about payment security.

I was just trying to finish my enterprise year-end review (doanh nghiệp năm tài chính) in Quảng Bình, and my local accountant handed me a list of documents—bank statements, tax filings, a signed declaration form—and then paused. “Oh,” she said, “you’ll need to send your personal ID number to the bank’s verification system via WeChat. Just the last digit, don’t worry.”

I froze.

Not because it was illegal. Not because it was unusual.

But because it felt… normal.

And that’s what scared me.

I’ve been selling smart trash bins in Vietnam for two years now. Small batch. Low volume. No fancy warehouse. Just me, a local agent, and a lot of late-night WhatsApp messages with logistics guys who speak broken English and perfect Vietnamese.

I thought my biggest risk was damage during shipping. Turns out, it’s not the boxes. It’s the data inside them.

Last week, I asked a fellow seller—someone who’s been here since 2020—how he handles bank transfers for supplier payments. He shrugged. “I send the account number, password, and my phone number to the supplier’s WeChat. They call me when they log in, and I give them the SMS code. Faster than bank apps.”

I didn’t say anything. I just nodded.

But later, alone in my rented room in Đồng Hới, I Googled “Coupang account trading Taobao” and found something chilling: Korean authorities confirmed over 45 cases in early 2026 where sellers on Chinese platforms shared not just login credentials—but full resident registration numbers, partial digits included—just to complete authentication.

And it wasn’t just gaming accounts.

It was bank accounts. E-commerce logins. Tax portals.

The same behavior.

The same logic: It’s just a code. It’s just one digit. They’re my friend. They won’t steal it.

I started thinking about the QR code system Vietnam is rolling out for food supply chains. The government wants traceability. Transparency. Digital accountability.

But here we are—on the ground—trading identities like lottery tickets.

Why does this keep happening?

Maybe it’s the speed.

In Vietnam, time isn’t money. Time is the currency.

If a bank verification takes three days through official channels, and WeChat takes three minutes… well, who’s going to wait?

Maybe it’s trust.

We assume local agents, suppliers, even strangers on WeChat are “safe” because they’re “from here.” We don’t ask for official seals or company stamps. We ask for a photo of their ID. Then we screenshot it. Then we send ours back.

Maybe it’s the lack of awareness.

Most small business owners I know never read the Terms of Service. They don’t know that under Vietnam’s Personal Data Protection Decree (Decree 13/2023/ND-CP), sharing even partial resident registration numbers without consent could be considered a violation.

I asked my accountant if she’d ever been audited for this. She laughed. “Audit? We’re a 3-person shop. Who’s going to care?”

And maybe… that’s the real problem.

It’s not the law that’s weak.

It’s the belief that the law doesn’t apply to us.

I used to think compliance was for big companies.

Now I think compliance is the only thing that keeps small companies alive.

One breach. One stolen identity. One frozen bank account. And suddenly, your year-end review isn’t about taxes—it’s about lawsuits.

I’ve seen it happen. A guy in Da Nang lost his business because someone used his WeChat to access his bank account, then transferred $12,000 to a fake supplier in Cambodia. He didn’t even notice until the tax office called.

He didn’t lose money.

He lost trust.

And in Vietnam, trust is harder to rebuild than capital.

🔍 FAQ: What Should You Actually Do?

Q: How do I securely complete enterprise year-end review procedures without sharing personal data over messaging apps?

  • Step 1: Use official government portals like the National Business Registration Portal (dangkykinhdoanh.gov.vn) for document submission.
  • Step 2: For bank verification, request an official letterhead request form—signed and stamped—and submit it in person or via courier.
  • Step 3: Never share full or partial resident registration numbers, passwords, or OTP codes via WeChat, Zalo, or SMS.
  • Key point: If someone asks for your ID digit, ask: “Can you send me the official form from your institution?” If they can’t, walk away.

Q: Is it legal to use third-party agents to handle my company’s financial verification?

  • Step 1: Confirm the agent is registered with the Ministry of Planning and Investment (MPI) as a legal service provider.
  • Step 2: Request their license number and verify it on the MPI’s public registry.
  • Step 3: Sign a written agreement that explicitly prohibits data sharing via unsecured channels.
  • Key point: Even if they’re “recommended,” you remain legally liable for how your data is handled.

Q: What’s the safest way to handle cross-border payments to suppliers in China or Korea?

  • Step 1: Use licensed payment gateways like Momo, ZaloPay, or VNPay for local transactions.
  • Step 2: For international transfers, use banks with Vietnam-Korea or Vietnam-China correspondent agreements (e.g., Vietcombank, BIDV).
  • Step 3: Never send login credentials. Use two-factor authentication via email or registered mobile apps only.
  • Key point: If a supplier insists on WeChat for payment, assume it’s a red flag—not a shortcut.

I don’t have a perfect solution.

I don’t know if the system will fix itself.

I only know that every time I send a document via WeChat, I feel a little less like a business owner—and more like someone playing a game where the rules keep changing, and I’m the only one reading the manual.

I used to think compliance was paperwork.

Now I think it’s self-preservation.

I’m not trying to scare anyone.

I’m just trying to stay awake.

Maybe different people will have different answers.

If you’ve ever been asked for a partial ID number over WeChat—just to “finish the process”—I’d like to hear about it.

You’re not alone.

And if you’re in Quảng Bình, or anywhere else in Vietnam, and you’ve got questions about enterprise year-end review, payment security, or just how to stop feeling like you’re playing Russian roulette with your data…
