A merchant identification number (MID) is a unique number assigned to a merchant by their acquirer. An acquirer is a financial institution that provides payment processing services to merchants.
How Does a Merchant Identification Number Work?
When a credit or debit card is swiped at a point-of-sale terminal, the MID is read from the card’s magnetic stripe. The MID is then used to route the transaction through the payment processing network. The MID is also used to identify the merchant in the network.

MIDs are typically four to six digits long. They are printed on the front of credit and debit cards, and are also stored in the card’s magnetic stripe. MIDs are used to route transactions through the payment processing network.
