Payment processors & prefixes

Payment processors & prefixes

Payment processors act as the invisible bridge between merchants and your bank. When you buy a coffee from a local cafe or software from an independent developer, you aren't paying them directly—you are paying their processor, which then routes the funds to the merchant.

Because of this architecture, the statement descriptor that appears on your credit card usually starts with a standardized prefix identifying the processor, followed by an asterisk, and then a truncated version of the actual merchant's name. The most common examples include 'SQ *' for Square, 'TST*' for Toast (frequently used by restaurants), and 'SP *' for Shopify.

This structure is highly efficient for small businesses that don't want to establish their own direct merchant accounts with Visa or Mastercard. However, it creates massive confusion for consumers. A charge like 'SQ *DAILY GRIND' might be unrecognizable if the cafe's legal business name ('Daily Grind LLC') doesn't match their storefront sign ('Main Street Coffee').

In the digital space, platforms like Paddle ('PADDLE.NET*'), Stripe, and PayPal process payments for thousands of SaaS applications and digital creators. If you see one of these prefixes, the key to identifying the charge is looking at the characters *after* the asterisk.

Most major payment processors offer consumer-facing lookup tools. If you have a mystery charge from Square or Paddle, you can enter the transaction details on their respective websites to retrieve a digital receipt, which usually reveals the exact store location, itemized receipt, and contact information for the merchant.
