If you are a merchant and you accept credit cards, debit cards, ATM cards, gift cards or any other form of electronic payment, your merchant services company has assigned you a merchant account number. This account number is associated with your bank account, and all plastic payments are routed through your merchant account until you "batch out," directing the merchant services bank to deposit the money into your business account.
Find your merchant account number
Check your terminal. Your merchant services account representative may have written or printed your merchant account number on a sticker and placed it on your credit card terminal itself.
Check your statements. You should receive a merchant account statement every month from your merchant services provider. Your merchant account number should be clearly listed on your statement.
Call your representative. Your sales representative can help act as a go-between between you and your company and help you find your merchant account number from their records.
