Merchant category code (MCC) and POS agreement illustration

When signing a merchant agreement with banks, merchants also declare the field in which they operate. On the bank side, this information is held as an MCC (Merchant Category Code).
A merchant may only sell products/services related to the line of business it has declared to its bank. It cannot sell in another line of business.

A merchant cannot act as an intermediary for the sales of another business.

What should a merchant do when it changes its line of business?

When a merchant changes its line of business, it is obliged to notify the bank with which it has a merchant relationship of this change.

In addition, using the POS device to provide financing or benefits to the company owner, employees or third parties is contrary to the laws of the Republic of Türkiye.

What sanctions are applied to merchants that do not comply with these rules?

  • The merchant's bank may file a criminal complaint against the company.
  • The merchant's bank may terminate the company's merchant agreement.
  • The merchant's bank may restrict its card acceptance authorization.
  • The merchant's bank may change the merchant's allocation terms.
