All merchants need to be compliant with PCI DSS v.3.2.1 but each payment brand has its own program for compliance, validation levels and enforcement.
Merchant levels are:
- defined by the payment brands
- determined by the acquirers
- based on transaction volume and type (i.e. eCommerce or card-not-present, face-to-face or card-present).
Your merchant level determines how you report/validate compliance. Depending on the acquirer's discretion, if they believe you are a high-risk merchant or if you've suffered a data compromise, they can enforce you to meet requirements for Level 1 merchants even if your transaction volumes are low.
