Setting merchant category codes

MCCs are used to classify businesses by the type of goods or services they provide. For example, grocery stores, hotels, and airlines all have different MCCs. These codes are often used for calculating interchange fees, authorizing payments, and preventing fraud, so it’s important that your connected accounts have MCCs that match their businesses.

Each Stripe account has exactly one MCC. To view the MCC for a specific account, you can retrieve the business_profile.mcc field on the account object.

Stripe automatically sets MCC codes for connected accounts, but you can choose to set them manually for Custom and Express accounts.

Setting MCCs automatically

Stripe automatically evaluates accounts to determine appropriate MCCs. This means you don’t need to build and maintain any custom logic. Generally, the industry listed in the Stripe Dashboard for the connected account is used to determine the MCC. This value is set during the onboarding flows for Standard and Express accounts, and in Connect Onboarding. You can set the MCC manually for accounts created with the API, or set explicitly in the same way for Express accounts.

If the industry that the user provides can’t be used, Stripe might use information from the connected account’s website to determine the MCC. If this also fails, the platform or Stripe’s default MCC (5734 Computer Software Stores) is used.

Sometimes accounts are flagged for manual review by Stripe. If this happens and Stripe determines the MCC on an account is inaccurate, we might update it. The new MCC can’t be manually changed by the platform, and an error is returned if the API is used to update the MCC.

Setting MCCs manually

You can set the MCC manually when you create accounts. The examples below use the code for Computer Software Stores (5734), but you can see a full list in the next section.

curl https://api.stripe.com/v1/accounts \
  -u 
sk_test_4eC39HqLyjWDarjtT1zdp7dc: \
  -d country=US \
  -d type=custom \
  -d "capabilities[card_payments][requested]"=true \
  -d "capabilities[transfers][requested]"=true \
  -d "business_profile[mcc]"=5734

If your connected accounts share an MCC, you can provide the code using business_profile[mcc] when you create accounts. In Connect Onboarding, your users won’t be asked for an industry. If you build your own onboarding UI, you won’t need to add a UI element for MCC.

If your connected accounts have different MCCs, Connect Onboarding will collect that information. If you aren’t using Connect Onboarding, you can provide a list of MCC options for users to choose from. Based on the user’s selection, you can pass an MCC appropriate for their business. If you don’t want to pass MCCs when you create accounts, you can update accounts with MCCs later.

Similar to an MCC that’s set automatically, Stripe can override an MCC set manually if the connected account is flagged for review and we determine the MCC is inaccurate.
