An “AIRWALXHK” charge on your credit card is a payment processed through Airwallex, a financial technology company with licensed payment operations in Hong Kong (the source of the “HK”). In almost every case, the charge is legitimate but misleading: you bought something from an online merchant that uses Airwallex to process card payments, and the processor’s name landed on your statement instead of the store’s.
Why the Merchant’s Name Isn’t on Your Statement
Card statements limit merchant descriptors to a short string of characters, so what you see is often an abbreviation rather than a storefront name. When a business uses a third-party processor, the processor’s identifier can fill that slot by default.1Airwallex. What Is This Charge on My Credit Card
Airwallex’s own documentation says the descriptor shown to a customer should default to the merchant’s registered business name, and merchants can configure dynamic descriptors (up to 32 characters) that display the business name or an order number.2Airwallex.

When a merchant skips it, you get the truncated processor label — “AIRWALXHK” — with no clue who actually charged you.
How to Trace the Charge
Before you call it fraud, try to find the purchase yourself. The fastest route is the dollar amount. Search your email, including spam, for the exact figure down to the cents. Order confirmations will usually surface the merchant immediately.1Airwallex. What Is This Charge on My Credit Card Statement dates can lag the actual charge by a few days, so look at the 72 hours before the posted date.
If email turns up nothing, try these:
- Search the descriptor itself in quotes online. Forum posts sometimes link a specific descriptor to a specific merchant.
- Call your card issuer and ask for the merchant category code (MCC). The four-digit code tells you the industry — travel, software, retail — which can jog your memory.
- Ask anyone else with access to the card: a spouse, a family member, an employee on a shared corporate account.
How to Dispute It If You Still Can’t Place It
If none of that works, you can dispute the charge. Under the Fair Credit Billing Act, your liability for an unauthorized credit card charge is capped at $50, and most card networks waive even that under zero-liability policies.4Federal Trade Commission.

To preserve your full legal rights, send a written dispute to your card issuer at the address designated for billing inquiries, not the payment address. Include your name, account number, the disputed amount, and why you believe it’s an error. The letter has to reach the issuer within 60 days of the statement date on which the charge appeared.6Consumer Financial Protection Bureau.

Once the issuer has your written notice, it must acknowledge the dispute within 30 days and finish its investigation within two billing cycles, up to a 90-day maximum. You can withhold payment on the disputed amount during that period without being reported delinquent, but you still have to pay the rest of the balance.5National Consumer Law Center.

When “Airwallex” Is Actually a Scammer
A separate problem worth knowing about: people pretending to be Airwallex. A February 2026 Better Business Bureau Scam Tracker report described an employment scam in which the perpetrators posed as Airwallex, recruited a victim to process fake “currency exchanges,” and stole more than $16,600. The real Airwallex confirmed to the victim that the operation was “an unknown third-party not related to Airwallex at all.”7Better Business Bureau. Scam Tracker Report 1203997
Airwallex has published a warning that impersonation scams using its name and logo are “on the rise.” The company says it will never ask for bank or card numbers, passwords, one-time passcodes, or any kind of payment such as a “processing fee” or “equipment deposit.” Legitimate company email comes from @airwallex.com addresses, and job offers go through a formal interview with written documentation. If you think you’ve been targeted, Airwallex advises cutting off contact, notifying your bank, and reporting the fraud to local authorities.8Airwallex Careers. Verify Airwallex Job
That kind of scam is a different animal from an unexplained line item on your statement. An “AIRWALXHK” descriptor by itself points to a real card transaction routed through Airwallex, not to someone emailing you claiming to be the company.
