- New passport, different number, your bank doesn’t know. Your account may already be at risk.
- A single word in a transaction description, e.g. “Bitcoin”, can trigger account restrictions under banks’ virtual currency risk controls.
- Frozen by the bank and frozen by the police require completely different responses.
- A Chinese national’s ID card can be valid for 20 years or more. Your passport expires in ten. That difference is why this problem falls disproportionately on foreigners.
- The “one year grace period” after passport renewal? No regulatory basis. It doesn’t exist.
Three types of freezes.
Three completely different problems.
Not all account restrictions are the same. Before you do anything, you need to know which type you’re dealing with, because the response is entirely different for each.
Bank-initiated restriction
This is the most frequently reported situation among expatriates. The bank’s compliance process has identified an issue, an expired passport number on file, a period of inactivity, an unusual transaction pattern, and restricted the account pending review.
There is no criminal implication. No court order. The bank can lift it once you resolve the underlying issue. This is inconvenient but fixable, usually in one branch visit.
Judicial or administrative freeze
A court, tax authority, or regulatory body has issued a formal freeze order, typically connected to a civil dispute, an unpaid debt, or a regulatory matter. The bank cannot lift this independently. You have to address it at the source, the court or authority that issued the order, before the bank will act. This takes longer and may require legal assistance.
Public security freeze
A police bureau has ordered the freeze in connection with a criminal investigation. This is the most serious type and the hardest to resolve. It is more common than many assume, not because the account holder has done anything wrong, but because their account received funds connected to a fraud network, even unknowingly. The bank cannot unilaterally lift a police-ordered freeze without authorization from the issuing bureau. You need to contact the specific police bureau that issued the order, which may be in a completely different city. This can take weeks or months.
If your account is restricted, and you ask the bank directly, they are required under banking freezing assistance rules to identify which authority ordered the freeze and direct you to contact that authority. Ask immediately, because your next step depends entirely on the answer.
The passport problem, and why it hits foreigners specifically
This is the most predictable cause of foreigner account restrictions, and the most preventable.
Chinese nationals aged 46 and over hold Resident Identity Cards with no expiry date. Those between 16 and 45 hold cards with 10 or 20-year validity. In practice, the compliance system encounters far fewer expired domestic ID cards per hed of poupulation than expired foreign passports, which typically run on five or ten-year renewal cycles.
Under China’s Financial Institutions Customer Due Diligence Measures, most recently updated and effective from January 2026, banks are required to conduct ongoing due diligence on customer identity, and must take action when identity documents on file are outdated or invalid.
An expired passport on file constitutes grounds for banks to require re-verification, and to suspend services if the customer fails to update documents within a reasonable period after notification.
In practice, what this means: when your passport expires and you receive a new one with a new passport number, your bank account is still linked to the old number. The system will detect the expiry.
At some point, sometimes immediately, sometimes weeks later, sometimes only when you attempt a transaction, the account will be restricted pending re-verification.
The bank should notify you and allow a reasonable period to update your documents. In practice, many people first find out when their card is declined.
The one-year rule
This circulates widely in expat WeChat groups: you have one year after passport renewal before your bank is affected. There is no regulatory basis for this. The regulations specify that banks must provide a “reasonable period” for document updates, but that period is not defined anywhere in the available regulation. Do not rely on a timeline that doesn’t exist in writing.
What to do instead
Update your bank records as soon as you receive your new passport. Do not wait for a restriction to appear. Most major banks currently require an in-person branch visit, though some now offer mobile app updates for certain document changes. Bring your new passport, your old passport, your current residence permit, and your employment contract.
Some branches process this in an hour. Some, particularly smaller branches with no prior experience handling the procedure, can take multiple visits. If you hit resistance, call the bank’s national customer service hotline while you are standing at the counter. A trained agent can confirm the correct policy directly to branch staff.
Five other triggers worth knowing
Name mismatches
If your new passport spells your name differently from the one used to open your account, a middle name added or dropped, a hyphen, a transliteration change, you have a problem. The name on your bank record must match your current passport exactly.
This affects not just your bank account but your ability to link WeChat Pay and Alipay, and can cause overseas transfers to be rejected. The resolution typically involves obtaining a certified letter from your embassy confirming both documents belong to the same person, or a notarized statement from a Chinese notary office, though specific document requirements may vary by bank and branch. It is fixable but takes effort and depends heavily on branch staff competence.
Dormancy
Dormancy thresholds vary by bank but typically range from one to two years of inactivity. Accounts crossing this threshold are commonly reclassified as dormant, restricting ATM and online banking functions. Check your bank’s specific terms, as thresholds differ. Reactivation requires an in-person branch visit. If you have accounts you rarely use, a salary account from a previous employer, a second account at a different bank, check them periodically.
AML transaction patterns
Single-day cash receipts or payments of RMB 50,000 (approximately USD 10,000) or more trigger mandatory large-transaction reports to China’s AML Monitoring and Analysis Center. Overseas wire transfers are subject to separate SAFE and PBOC reporting requirements. These are compliance filings, not automatic blocks, but they can precede a request for documentation.
Patterns that draw heightened scrutiny include funds arriving from multiple overseas sources, rapid inflow and immediate outflow across borders, and regular large transfers without clear documentation of their purpose.
If your salary is paid from an overseas account, keep payslips, tax payment records, and your employment contract accessible. Banks have requested all three during AML reviews of entirely legitimate salary transfers.
The crypto word trigger
Transaction descriptions that include cryptocurrency-related terms, including incidental words like “Bitcoin,” “DOGE,” or “USDT”, have triggered account restrictions under banks’ virtual currency risk-control programs. This applies even if the transaction itself has nothing to do with cryptocurrency. The account may be restricted before you are notified. Check the description field before confirming any transfer.
Visa and work permit changes
Changing jobs, renewing a residence permit, or experiencing a gap between permits is not in itself a trigger for account restriction under current regulations, though such changes may complicate any compliance review that is already underway. Keep your bank’s records current when your situation changes.
If it happens
For a bank-initiated restriction (the most frequently reported scenario), go to a branch in person. Bring your current passport, your old passport if the issue is a passport change, your current visa or residence permit, and your employment contract. For transaction-related reviews, also bring payslips and tax payment certificates showing the source of incoming funds.
For straightforward identity updates, resolution typically happens the same day or within one to two visits. AML-triggered reviews involving transaction explanations can take several days to a few weeks.
If the branch is unhelpful or unfamiliar with the procedure, call the bank’s national customer service hotline while you are at the branch.
For cases involving criminal investigations, public security information is accessible to other institutions. Don’t try to solve this by opening a new account at another bank. It won’t fix the problem and may complicate it.
Under Article 39 of China’s Anti-Money Laundering Law (effective January 1, 2025), if you formally object to the bank’s restriction, the bank must review your complaint and respond within 15 days. If unresolved, you may initiate litigation directly in the people’s courts.
For judicial or public security freezes, identify the freezing authority first, the bank must disclose this upon request, and engage directly with that authority. Legal assistance is advisable for anything beyond a straightforward bank-level restriction.
Four things to do before there’s a problem
- Update your bank records every time you get a new passport. Do it the same week. In person. Don’t wait for the bank to contact you.
- Use every account you hold at least once every six months or so. A small transaction is enough. Dormant accounts get restricted.
- Check transaction descriptions before confirming transfers. Particularly any description that could be read as cryptocurrency-related.
- Keep a folder with your current payslips, tax records, and employment contract. If a bank requests source-of-funds documentation, you want to be able to produce it the same day.
Account access problems in China are almost always preventable. The ones that aren’t are almost always fixable, if you know which type of problem you’re dealing with and respond accordingly.
