MCC 7379 is the code used to categorize COMPUTER MAINTENANCE, REPAIR AND SERVICES by the International Organization for Standardization (ISO). This classification applies to businesses that provide computer repair, hardware installation, and various software support services. It also covers transactions for specialized tasks like data recovery and routine system maintenance for clients.

Which businesses fall under MCC 7379?

MCC 7379 applies to a broad range of IT service establishments:

Computer Repair Shops: These stores fix hardware malfunctions and software problems for both individuals and businesses. Services include screen replacements, virus removal, and component upgrades, like those offered by uBreakiFix.
On-site Tech Support Services: Technicians from these companies travel to homes or offices to resolve computer and network issues directly. Companies like HelloTech or Geek Squad provide this type of hands-on assistance.
IT Consulting Firms: These firms offer expert advice to businesses on technology strategy, system architecture, and security protocols. They guide companies on optimizing their digital infrastructure for better performance and security.
Managed Service Providers (MSPs): MSPs provide continuous, subscription-based IT support and management for businesses. They proactively monitor systems, manage network security, and handle routine maintenance for their clients.
Data Recovery Services: These specialized labs retrieve lost or inaccessible information from damaged storage devices like hard drives and SSDs. Businesses such as DriveSavers perform these complex technical recovery operations.
Custom Software Support: These businesses offer installation, configuration, and troubleshooting for specific or proprietary software applications. They help other companies properly implement and maintain specialized programs for their operations.

Business implications of MCC 7379

Payment networks including Visa, Mastercard, American Express, and Discover use MCC 7379 to categorize transactions, which affects several aspects of business operations. These networks assess the risk level of a business based on its MCC. For IT services under MCC 7379, this classification can influence the interchange rates charged for credit card processing, as service-based industries sometimes face different fee structures than retail.

Beyond transaction fees, the MCC code also has an impact on other financial and operational functions for both the business and its customers.

Expense tracking

Companies rely on MCC 7379 to automatically categorize purchases on corporate credit card statements. This allows accounting software to sort payments for computer maintenance or IT support, simplifying the process of tracking technology-related expenditures for budgeting and tax purposes.

Financial analysis

Businesses analyze spending data associated with MCC 7379 to understand their IT service costs. This information helps them identify spending patterns, forecast future technology expenses, and manage departmental budgets more effectively by showing where funds for maintenance and support go.

Compliance and auditing

The consistent application of MCC 7379 creates a clear audit trail for financial reviews. It allows auditors to quickly verify that expenses claimed for IT services are legitimate and properly categorized.

Rewards and customer behavior

Credit card issuers use MCCs to determine rewards eligibility, such as bonus points on business-related spending. Customers with cards that offer extra rewards for services might prefer businesses coded under MCC 7379, influencing their choice of IT provider.

How to verify your business's MCC

IT service owners should confirm their MCC classification to ensure proper transaction processing and avoid customer confusion regarding rewards eligibility. If you find out that your business is incorrectly classified—for example, a computer repair shop coded as an office equipment dealer—contact your payment processor immediately to request reclassification.

Here's how to verify is your MCC classification is set up correctly:

Contact Your Payment Processor: Your merchant services provider assigned the MCC during account setup. To verify your classification, contact their customer service team or review the details in your original merchant agreement documents.
Review Processing Statements: Monthly merchant statements typically display the assigned MCC. Look for a four-digit number listed in the account information or business profile section of your statement to find your code.
Check with Your Acquirer: The acquiring bank or financial institution that processes your payments maintains the MCC in their system. Their merchant support team can confirm your current classification upon request.
Test Transaction Method: Some merchants run a small test transaction on a personal credit card and check how it appears on the statement. This method is less reliable than direct confirmation from your processor.

How to choose a reliable payment service provider

Your MCC 7379 classification directly affects interchange rates and processing requirements. Since payment processors handle these transactions differently, your choice of provider matters. Variations in pricing models, settlement speeds, and support quality can have a cumulative effect on your business. Consider the following factors when you select a payment partner.

Transparent pricing: Flat-rate pricing models offer predictability over complex tiered structures that hide fees. This clarity helps you forecast expenses accurately. The JIM tap-to-pay app for iPhone and Android charges 1.99% per transaction with no setup costs, monthly fees, or premium card surcharges.
Payment method support: Your processor should accept major cards like Visa and Mastercard, plus digital wallets such as Apple Pay and Google Pay. This meets modern customer expectations and simplifies payment.
Fast fund access: Quick access to funds helps manage cash flow, letting you pay suppliers for parts or cover payroll without delay. Look for processors that offer fast or instant settlements for your IT service business.
Security: Protect customer data with a processor that uses tokenization and encryption. Tokenization replaces card details with a unique code for each sale, so sensitive information is never stored on your device or servers.
Reporting: Your processor should offer clear transaction data. Some platforms use AI-powered analytics to simplify this process. JIM's AI assistant provides sales reports and transaction history through a simple chat interface.

Streamline payments with JIM

JIM offers IT service owners a straightforward payment processing solution. The JIM tap-to-pay app converts your iPhone or Android phone into a terminal that accepts contactless payments, so you need no extra hardware. It uses NFC technology to complete transactions directly on your device. You pay a flat 1.99% per transaction, with no setup costs, monthly fees, or variable rates for premium cards.

You can also send payment links for remote jobs (for example, to invoice a client after a remote software fix) at a rate of 4.99% + $0.30 per sale. Your funds become available instantly on a JIM Visa Prepaid Card. Add this card to Apple Pay or Google Pay to use your revenue immediately.

Frequently Asked Questions

Question

What is Merchant Category Code 7379?

Merchant Category Code 7379 is a four-digit classification number assigned to computer maintenance, repair, and services by payment networks and the International Organization for Standardization (ISO). This code identifies transactions from businesses that offer IT support, hardware repair, and data recovery. Payment processors use this classification to set interchange rates, generate financial reports, and determine rewards eligibility for cardholders.

Is Merchant Category Code 7379 high-risk?

MCC 7379 is considered a standard-risk category by most payment processors. This classification reflects a moderate potential for chargebacks, since clients may dispute service quality or outcomes. As a result, businesses under this code receive favorable interchange rates and face standard underwriting, avoiding the higher fees and stricter scrutiny applied to high-risk industries.

Can a business have multiple MCC codes?

A business is typically assigned one MCC per merchant account, reflecting its primary source of revenue. However, companies with distinct and separate operations can maintain multiple merchant accounts, each with a different code. For example, a large electronics retailer (MCC 5732) might also run an in-house computer repair department. This service division could have its own merchant account classified under MCC 7379 to process payments specifically for its IT support activities, separating them from retail product sales.

What happens if my MCC code is wrong?

An incorrect MCC creates several problems. Clients might not get the credit card rewards they expect for service expenses, which can influence their decision to return for future IT support. Furthermore, your business could be assigned improper interchange rates; you might overpay on fees or face penalties from payment networks if you benefit from a lower rate intended for a different industry.

Can merchants choose their MCC code?

Merchants do not have the freedom to choose their own MCC code. Instead, payment processors assign the classification based on the business's main source of income, following standards set by the ISO and payment networks. If a business owner finds that their assigned code does not accurately represent their services, they have the option to contact their processor and formally request a review for reclassification.

How does MCC 7379 affect my payment processing costs?

MCC 7379 directly influences the interchange rates you pay on each transaction. As a standard-risk service category, it typically commands moderate rates—lower than high-risk industries but higher than retail sectors like grocery stores. The exact impact on your bottom line, however, depends on your processor’s pricing model.

Processors with interchange-plus pricing pass these variable rates directly to you, so your costs fluctuate with every card. In contrast, flat-rate processors like JIM, available for both iOS and Android, absorb this variability and charge a consistent fee regardless of card type.
