Merchant Category Codes API
ISO 18245 Merchant Category Codes (MCC) as an API — the 981 four-digit codes that Visa, Mastercard and other card networks use to classify a merchant's line of business. Look up any code (e.g. 5812 → Eating places and Restaurants, 5411 → Grocery Stores/Supermarkets, 3000 → United Airlines), search by description (e.g. "hotel", "airline", "pharmacy"), filter by IRS-reportable status, or list them all. Each record carries the network/edited description, USDA and IRS descriptions and whether the category is IRS 1099-reportable. Ideal for payments, fintech, expense management, fraud analysis and transaction enrichment.
