Mystery card charge decoder

It is the short text a payment processor stamps next to a charge on your bank or card statement. It usually combines the processor's own prefix (such as SQ *, WP* or PADDLE.NET*) with the trading name of the business you actually paid. The prefix tells you which company moved the money; the name after it tells you the merchant.

Three common reasons. The business trades under a different legal or billing name than its shopfront. It uses a payment processor or marketplace that brands the descriptor with its own name (Square, SumUp, PayPal, Paddle). Or it is a subscription billed by a parent company. Decoding the prefix narrows down which of these it is, so you know where to look next.

Not on its own. The large majority of mystery descriptors are legitimate payments dressed in a processor's prefix or a parent company's billing name. Treat it as suspicious only if you cannot match it to anything you bought, it recurs without a subscription you remember starting, or the amount is wrong. In that case contact your bank, not the descriptor, and ask them to trace or dispute it.

The asterisk or underscore simply separates the processor prefix from the merchant name (SQ *MERCHANT, ZETTLE_*MERCHANT). "PA" or "AUTH" can indicate a pending authorisation that has not yet settled. A small temporary amount, often £0 or £1, is usually a card-verification check by a hotel, fuel station or subscription service, and it drops off within a few days.

Yes, within limits. Your acquirer or processor sets your statement descriptor, and you can usually request that it shows your trading name plus a contact detail rather than a generic prefix. Clear descriptors cut chargebacks and "I do not recognise this" disputes. If you are not sure what your customers see, ask your provider, or compare providers that give you control of the descriptor.

It identifies the payment processor from the descriptor prefix, which is reliable for the major UK acquirers, readers and gateways listed. It cannot identify the specific merchant, confirm an amount, or prove a charge is legitimate, because descriptors are not unique and can be reused. Use it to understand who processed a charge, then verify the merchant through your own records or your bank.
