We will now briefly touch on merchant levels and transaction volumes. A merchant’s level will be defined by the Payment Brands and determined by the acquirer, or by payment brand where it is an acquirer. This means an organization may be different levels for different payment brands.
Transaction volumes: Each acquirer determines merchant transaction volumes, and they are generally based on the aggregate number of transactions for a merchant. However, the Card Brand policy varies according to each individual brand and/or their acquirers. If a merchant has multiple lines of business or multiple acquirer relationships, the merchant should consult with their acquirers and/or their payment brands to determine their validation level.
The decision about a merchant’s validation level belongs to the acquirers, since they are the ones responsible for their merchant’s compliance.
