What Is a Merchant Category Code (MCC) and Why Should I Care?

A Merchant Category Code (MCC) is a four-digit number assigned to your business that describes the type of goods or services you provide. This classification impacts everything from your processing fees to your risk profile and even your ability to be approved for a merchant account. Understanding your MCC is crucial if you want to manage your payment processing more effectively.

What Is an MCC Used For?

An MCC tells banks, card networks, and payment processors what industry your business operates in. Each industry is associated with a different level of risk and fee structure. For example, an online supplement retailer has a different MCC than a medical clinic, and each carries unique risks related to refunds, chargebacks, and compliance.

Issuers use MCCs to:

• Determine processing fees
• Evaluate approval risk
• Apply reward point eligibility for consumers
• Enforce restrictions on specific types of purchases

How Do MCCs Affect Risk Classification?

MCCs directly impact how your business is classified during underwriting. Some codes are deemed high-risk due to high chargeback rates, legal complexity, or reputational risk. According to RevitPay’s payments consulting page, your MCC can determine whether you're approved quickly, or flagged for further review.

For example, a business classified under travel, adult products, or online gaming may be automatically marked as high-risk. This often leads to longer approval times, higher fees, or the need to work with a high-risk payment processor.

Can You Change Your MCC?

Most merchants are assigned an MCC when they open a merchant account. However, if your business evolves or if your current MCC is costing you higher fees, you may be able to request a change. The process typically involves:

• Submitting documentation about your product/service
• Updating your website and terms to reflect your core offering
• Working with your payment processor to re-evaluate your classification

Consultants who specialize in merchant services, like those at RevitPay, can guide you through this process and help you optimize your classification.

Why Is the MCC Important for Approval?

Banks and payment processors use MCCs as a filtering mechanism. Certain MCCs, such as 5967 (supplements) or 7995 (gambling), are associated with high rates of chargebacks and fraud. This makes approval harder and may require more documentation, reserve funds, or third-party audits.

The high-risk vs low-risk merchant classification article explains that factors like your MCC, revenue volume, and chargeback history determine your risk level. Businesses deemed high-risk may even be listed on the Terminated Merchant File (TMF), which can severely limit future processing options.

How Do MCCs Impact Processing Fees?

Payment networks use MCCs to assign an interchange rate, the base fee you pay for each transaction. High-risk categories often carry higher rates due to the increased likelihood of disputes or fraud.

For instance, a coaching business may have an MCC classified under “professional services” with a lower fee structure than a subscription box company classified under “continuity/recurring billing,” which is viewed as higher risk.

Choosing the right MCC, and negotiating with the right processor, can lead to significant cost savings over time.

What Happens If You're Misclassified?

If your MCC doesn’t accurately reflect your business, several problems can occur:

• You may be charged incorrect processing fees.
• Your transactions may be flagged for fraud or rejected.
• You may be excluded from certain promotions or industry-specific tools.
• You may unknowingly violate card network rules.

An inaccurate MCC can also result in regulatory compliance issues, particularly in industries with tight restrictions such as CBD, firearms, or medical services.
