MCC 5065 is a merchant category code used by the International Organization for Standardization (ISO) to classify businesses that sell electrical parts and equipment. This code generally applies to wholesale distributors of electrical apparatus, wiring supplies, and construction materials. It also covers retailers that sell these items to contractors or the general public, which includes a wide range of electrical component sales transactions.

Which businesses fall under MCC 5065?

MCC 5065 applies to a broad range of electrical supply establishments:

Electrical Wholesalers: These businesses sell electrical parts and equipment in bulk, primarily to contractors and industrial clients. Companies like Graybar or WESCO International are prime examples of distributors operating under this code.
Lighting Fixture Retailers: This category includes stores specializing in the sale of lighting products, from residential lamps to commercial fixtures. You might find this code used by specialty shops or chains like Lamps Plus.
Electrical Supply Stores: Unlike massive home improvement centers, these stores focus specifically on electrical components for professionals and DIY enthusiasts. Establishments such as City Electric Supply fit this description perfectly.
Wire and Cable Distributors: These suppliers focus on providing various types of electrical wiring, data cables, and fiber optics. Anixter is a well-known global distributor that falls into this specific category.
Automation Component Suppliers: Businesses in this niche distribute parts for industrial control systems, including sensors, motors, and programmable logic controllers. Distributors for brands like Rockwell Automation or Siemens often use this MCC.
Solar Equipment Suppliers: This includes wholesalers and retailers that sell solar panels, inverters, racking, and other photovoltaic system components. Many regional solar equipment distributors would be classified under MCC 5065.

Business implications of MCC 5065

Payment networks including Visa, Mastercard, American Express, and Discover use MCC 5065 to categorize transactions, which affects several aspects of business operations. These networks assess a business's risk profile based on its MCC. For MCC 5065, which covers wholesale electrical parts, the risk is generally considered moderate, influencing the interchange rates charged for transactions.

Beyond risk assessment and transaction fees, the MCC code serves other operational functions that streamline financial management for both the business and its customers. These applications provide greater clarity and control over spending.

Expense tracking

Companies use MCC codes to automatically sort purchases on corporate card statements. This simplifies expense reporting for electrical supplies. For contractors, this clear categorization can also support accurate tax deductions for job-related materials and equipment purchases.

Financial analysis

Businesses analyze spending patterns associated with MCC 5065 to monitor project costs and manage budgets. This data allows procurement teams to track expenditures on electrical components, identify savings opportunities, and forecast future expenses with greater precision.

Compliance and auditing

The consistent application of MCC 5065 creates a clear audit trail. This helps companies verify that expenses are legitimate business purchases, which simplifies internal reviews and supports regulatory compliance requirements.

Rewards and customer behavior

Credit card issuers often tie rewards programs to specific MCCs. Some cards offer extra points for B2B purchases, influencing a contractor's decision to buy from a supplier coded under MCC 5065 to maximize their benefits.

How to verify your business's MCC

Electrical parts and equipment business owners should confirm their MCC classification to allow for proper transaction processing and avoid customer confusion regarding rewards eligibility. If you find that your business is incorrectly classified, for example, an electrical parts wholesaler coded as a general hardware store, you should contact your payment processor immediately to request reclassification.

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

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

How to choose a reliable payment service provider

Your MCC 5065 classification directly affects interchange rates and processing requirements. Choosing the right payment processor is therefore an important business decision. Different providers handle transactions for electrical suppliers with variations in pricing, settlement speed, and support that can accumulate over time. Consider the following factors when you select a provider.

Transparent pricing: Opt for flat-rate pricing to avoid complex interchange-plus or tiered models. 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 all major credit cards, including Visa, Mastercard, and Discover, along with digital wallets like Apple Pay and Google Pay to meet modern customer expectations.
Fast fund access: Quick access to funds is important for managing cash flow in the electrical supply industry. Instant settlements help you cover immediate expenses like restocking inventory, making supplier payments, or meeting payroll.
Security: A secure processor uses tokenization and encryption to protect customer data. JIM uses tokenization for every transaction, so card numbers are never stored on your device, which reduces your liability.
Reporting: Look for a provider that offers detailed analytics. JIM's AI assistant provides sales reports and transaction history through a chat interface, offering quick access to business performance data.

JIM offers electrical supply business owners a straightforward solution to process payments. The JIM tap-to-pay app transforms your iPhone or Android into a payment terminal with no extra hardware. It uses NFC technology to accept payments directly on your phone. You pay a flat 1.99% per transaction, with no setup costs, monthly fees, or variable rates. For remote sales, you can use payment links (ideal for custom invoices) at 4.99% + $0.30 per sale.

Frequently Asked Questions

Question

What is Merchant Category Code 5065?

Merchant Category Code 5065 is a four-digit classification number assigned to businesses that sell electrical parts and equipment by payment networks and the International Organization for Standardization (ISO). This code identifies transactions from wholesale distributors and retailers of electrical supplies. Payment processors use this code to set interchange fees, generate reports, and manage customer rewards programs.

Is Merchant Category Code 5065 high-risk?

Payment processors classify MCC 5065 as a standard-risk category. This classification stems from the predictable B2B transaction patterns and lower chargeback frequency common in the wholesale electrical supply industry. As a result, businesses under this code benefit from moderate interchange rates, avoiding the higher fees associated with high-risk merchants.

Can a business have multiple MCC codes?

A business typically receives one primary MCC code that reflects its main revenue source. However, companies with distinct business segments can maintain multiple merchant accounts, each with a different code. For example, a large home improvement store classified under a general hardware MCC might also run a separate wholesale division for electrical contractors. This division would likely use its own merchant account with the MCC 5065 classification to accurately track its bulk sales of electrical equipment.

What happens if my MCC code is wrong?

An incorrect MCC code creates both financial and customer-related problems. Contractors who expect credit card rewards on supply purchases might not get them, a frustration that could influence their future purchases. Furthermore, your business may be subject to improper interchange rates, which could mean you overpay on transaction fees or receive unearned discounts that violate payment network rules.

Can merchants choose their MCC code?

Merchants do not get to choose their own MCC code, as this classification is not self-selected. Payment processors assign the code after they evaluate a business's primary source of revenue against established guidelines from the ISO and card networks. However, if a business owner believes their assigned code is a poor fit for their operations, they can contact their processor to request a reclassification.

How does MCC 5065 affect my payment processing costs?

Your MCC 5065 classification directly influences the interchange rates you pay on every transaction. This code places your business in a moderate-risk category, so your rates are typically lower than those for high-risk industries but higher than what grocery stores or gas stations pay. The final effect on your costs, however, depends on your payment processor's pricing structure.

Processors with interchange-plus models pass these variable rates directly to you, which means your costs fluctuate with each card type. In contrast, flat-rate processors like JIM absorb this variability and charge you a consistent fee for every transaction, regardless of the card used.
