A statement descriptor is the text identifying a merchant that appears on a customer's card or bank statement and in their banking app for a payment. It is another name for a billing descriptor, the main entry, and is the term used by several online payment platforms in their documentation and settings.
A statement descriptor usually combines a fixed part, such as the merchant's trading name registered with its acquirer, and sometimes a variable part sent with each transaction, known as a soft descriptor, that describes the product or order. Card networks limit its length and characters, and require it to identify the business the customer dealt with. The related term merchant descriptor is also used interchangeably.
A clear statement descriptor helps customers recognise their purchases. When they do not, they may contact their bank and raise a chargeback, so merchants often review how their descriptor appears after changing brand names or payment providers.
