Payment rules

Merchant category code [MCC]

An acquirer-assigned business classification, not permission to sell restricted products.

GlossaryUpdated 2026-09-24
01

Business classification

The code can influence pricing, authorization and monitoring.

02

Acquirer assignment

The acquiring bank assigns the code during setup. Ask it to explain an unclear classification.

03

Accurate disclosure

An unrelated code does not authorize products the provider does not accept.

The short answer

An MCC is a four-digit merchant category code used to classify a business in payment processing. The acquirer assigns it during account setup.

The code should reflect the actual business. It is not permission to sell products a provider does not accept.

What it influences

The code can affect transaction pricing, authorization and monitoring. Product acceptance still depends on the provider's review and rules.

If the code looks wrong

Ask the acquirer to explain the classification. Provide the real products, buyers and channels. Do not use an unrelated category to avoid disclosure or restrictions.

For research suppliersThere is no universal code Scale can assign. Confirm both classification and category acceptance with the acquiring bank.
A useful next step

Confirm classification and acceptance.

Provide the actual products, buyers and channels. There is no universal research-supply code Scale can assign on your behalf.
