An MCC classifies an accepting outlet or activity - not a merchant identity.

Structure of a Merchant Category Code (MCC).

An MCC is a four-digit number that classifies the type of goods or services a business offers. MCCs were originally developed for tax reporting purposes but are now a key piece of payments processing. MCCs also provide a number of other benefits to an issuer’s card program, such as helping gather data to understand cardholders’ spending.

MCCs and their definitions are set by ISO 18245.

Payment-processing providers assign MCCs to businesses to determine which fees to charge for using their payments services, depending on factors such as a business’s level of risk. Most MCCs are recognised by the majority of card issuers, but some card networks have their own set of MCC variations.

MCC Ranges.

A frustrating aspect of MCCs is that there is not one universally accepted set of merchant category codes used by all parties. That said, the category code ranges are consistent. Here’s a rundown of the code ranges for different industries:

Broad activity ranges, not an exhaustive list of assigned MCCs
RangeBroad activity
0001–1499Agricultural services
1500–2999Contracted services
4000–4799Transportation services
4800–4999Utility services
5000–5599Retail outlet services
5600–5699Clothing shops
5700–7299Miscellaneous shops
7300–7999Business services
8000–8999Professional services and membership organisations
9000–9999Government services

Why MCCs matter.

The code tells a payment network what kind of merchant is accepting a card. Banks and processors use it alongside transaction and merchant data when they assess risk, set controls, monitor disputes and determine applicable pricing. The MCC alone is not a risk score or a fixed processing fee.

Interchange rate

Network interchange schedules vary by merchant category, card product, region and sales channel. Some categories may earn special rates. The MCC helps select a relevant category, but it does not determine a business’s total processing fee on its own.

Cardholder fees

Some MCCs, such as government payments, can qualify for service-fee programmes where network rules and local law allow. The code helps identify eligible transactions, but merchants and acquirers must meet conditions and disclose a fee to cardholders.

High-risk merchant identification

Acquirers and processors use MCCs as one signal when assessing a business’s activity. Some categories require special registration or controls. Overall risk also depends on channel, geography, history and behaviour; an MCC alone is not a fraud score.

Chargeback protection

The MCC can affect dispute rules and monitoring, especially for card-not-present sales or categories with more fraud or refunds. Processors also consider the merchant’s dispute record, billing and controls. The category does not guarantee protection.

Tax purposes

MCCs categorise purchases in statements and reporting systems, including tax reports. In some regions, they help flag reportable transactions. Tax treatment still depends on the underlying purchase and local tax rules, not solely on a merchant’s MCC.

Merchant onboarding

Acquirers check that the assigned MCC reflects a business’s primary activity for payments. Some categories require registration, documents or monitoring. Businesses can ask for a category review, while acquirer and network rules govern that decision.

Keep your classification accurate.

  1. Check the assigned code.Find it in your merchant account details or ask your acquirer or payment provider, then compare its description with the relevant network list.
  2. Request a correction when needed.Explain your primary activity and provide supporting material such as your website, product list and sales mix. The acquirer decides which code applies.
  3. Manage actual performance.Use clear billing descriptors and refund terms, appropriate fraud controls and dispute monitoring. A new MCC cannot substitute for these controls.

What MCC can - and cannot - tell you.

An MCC classifies a merchant’s business activity. Some dedicated codes identify a named travel brand or a particular type of transaction instead of a broad business category.

What MCC can indicate

  • The merchant’s primary business category
  • The broad type of goods or services offered
  • A specific brand for certain airline, hotel or car-rental codes
  • The transaction category for certain financial or cash-related codes

What MCC cannot determine

  • A unique merchant account, terminal or storefront
  • The exact items in an individual purchase
  • The merchant’s acquirer, processor or account details
  • A fixed processing fee, fraud score or approval outcome

MCC FAQ

What does MCC stand for?

Merchant Category Code. It is a four-digit classification of the merchant's business activity used in card payments.

Is an MCC the same as a merchant ID?

No. An MCC describes a category shared by many merchants. A merchant ID identifies a particular merchant relationship within an acquirer's systems.

Why do descriptions differ between lists?

Card networks maintain operational code lists alongside the ISO standard. Titles, detail and coverage can differ by publisher and version, so Aurato shows list-specific interpretations where available.

Can one business have more than one MCC?

It can, for example where different outlets or activities are classified separately. The MCC on a particular card transaction depends on the accepting merchant setup.
