The ability of acceptor in Checks is only granted to banks. Nevertheless, by referring to the Turkish Commercial Code (TCC) 673 in the regulation on checks, it was created the impression that outside the bank could also be shown as drawee. This false impression was reflected in both textbooks and judicial decisions. Whereas in the doctrine, the provision of TCC 673 is considered within the scope of bank checks in terms of checks. However, it is controversial whether bank checks, which are frequently encountered in practice, are legally valid checks. The bank serial number and datamatrix application accepted for checks turned the checks into fully printed negotiable instrument. In this context, the provision of the TCC 673 on the stating of the issuer as the addressee has become meaningless. However, the datamatrix application has significantly limited not only passive check licenses, but also active check licenses. In this study, first of all, the problem of whether persons outside the bank can be shown as acceptor within the framework of the capacity to be addressed in checks and how the provision of TCC 673 should be applied in terms of checks was clarified. Then, the status of bank checks in terms of the ability to deal with and the solutions that can be brought within this framework and the problems caused by the datamatrix application in terms of checks were examined.
