MID numbers are unique identification numbers that are assigned to specific merchant accounts. This number is used by the card brands (Visa, MasterCard, Discover, and American Express) to identify the merchant during credit card processing.
If you're a new merchant, you will need to contact your acquirer (bank or credit card processor) and request a MID number. Once you have obtained your MID number, you will need to provide it to your payment gateway so that they can properly route your transactions.
If you're already processing credit cards, you can find your MID number on your most recent statement from your acquirer. It will be listed as the "merchant ID" or "MID." If you cannot find your MID number on your statement, you can contact your acquirer and they will be able to provide it to you.
They will use this number to properly route your transactions. If you have any questions about MID numbers or need help finding yours, feel free to contact us and we'll be happy to assist you. Thanks for reading!
