A Z-category merchant is a high-risk merchant classification used by payment platforms to flag businesses requiring enhanced monitoring due to industry type, transaction patterns, or compliance exposure.
Merchants are assessed based on risk indicators such as chargebacks, regulatory exposure, and transaction behaviour. Z-category merchants face stricter controls.
Risk classification protects payment ecosystems from fraud and misuse while supporting regulatory compliance.
Maintaining compliant operations and clean transaction behaviour helps merchants avoid high-risk classification and operational restrictions.
