A guide for underwriters at ISOs and Acquirers onboarding MCC 5331 variety store merchants, covering risk assessment, fraud signals, and the underwriting questions that matter.
If you're underwriting a variety store, MCC 5331 concentrates risk around very low tickets at extreme volume, gift card and prepaid load fraud, and cashier-level voids and refunds. Like discount formats, the exposure builds through frequency rather than ticket size. Here's what to look for.
