Understanding Merchant Identification Number: A Key to Transaction Processing

Definition & Meaning

A Merchant Identification Number (MIN) is a unique identifier assigned to each merchant by an acquiring organization, such as a financial institution, Independent Sales Organization (ISO), Merchant Service Provider (MSP), or payment processor. This number plays a critical role in the payment processing ecosystem, helping to identify the merchant during various transaction-related activities, including daily processing, adjustments, chargebacks, and end-of-month fee calculations.
