How to Find Credit Card Merchant Category Codes

To find a merchant category code (MCC), you can inspect your past credit card transaction details online, download your credit card statement as a spreadsheet, or use official search tools like the Visa Merchant Locator. Knowing these four-digit codes is the absolute best way to guarantee you earn bonus points or cash back on every purchase.

Whether you are trying to maximize a 4x multiplier on dining, verify if your local health food store counts as a grocery store, or ensure a major purchase qualifies for a sign-up bonus category, the MCC is the ultimate arbiter. If you have ever made a purchase expecting a high reward rate only to see it earn a measly 1%, you have fallen victim to an unexpected merchant category code.

What Are Merchant Category Codes (MCCs) and Why Do They Matter? #

A Merchant Category Code (MCC) is a four-digit number assigned to a business by credit card processors (such as Visa, Mastercard, American Express, and Discover) when the merchant first begins accepting card payments. This code classifies the type of goods or services the business provides.

Originally, MCCs were established by the IRS to track business payment reporting, but today they serve as the underlying framework for the entire credit card rewards ecosystem. When an issuer like Chase, Citi, or American Express designs a card that offers “3x points on dining” or “5% cash back on groceries,” their systems do not look at the name of the store where you shopped. Instead, they run an automated rule: If the MCC matches a pre-approved list of codes for that category, award the bonus points.

For example, a business might have “Cafe” in its name, but if its payment processor categorized it under MCC 5411 (Grocery Stores and Supermarkets) instead of MCC 5812 (Eating Places and Restaurants), your card’s dining bonus will not trigger.

Here are a few common, high-value MCCs that reward seekers should know:

  • 5411: Grocery Stores and Supermarkets
  • 5812: Eating Places and Restaurants (Dining)
  • 5814: Fast Food Restaurants
  • 5541 & 5542: Service Stations and Automated Fuel Dispensers (Gas)
  • 4111: Local Passenger Transportation (often covers transit, trains, and ferries)

If you want to ensure your spending aligns perfectly with your cards’ bonus categories, you must learn how to identify these codes.

How to Find MCCs for Your Past Transactions #

If you have already made a purchase and want to see how it coded, you can look up the transaction details directly through your credit card issuer. While some issuers make this incredibly easy, others hide the exact four-digit code, requiring you to look for plain-text equivalents or download raw data.

Chase #

Chase does not display the raw four-digit MCC on its standard online portal or mobile app, but it does show the plain-text category.

  1. Log in to your Chase online account.
  2. Click on the card you used and navigate to your transaction history.
  3. Click on the specific transaction to expand the details.
  4. Look at the Category line. It will say something like “Groceries” or “Food & Drink.”

If you need the exact four-digit code, you can download your monthly statement as a CSV file. Go to your statements, select the download option, choose the Spreadsheet (Excel/CSV) format, and open it. The spreadsheet often exposes the raw transaction categories or specific merchant details that reveal how the charge was processed.

American Express #

American Express is relatively transparent about merchant categorization on its website, though it does not explicitly list the four-digit code on the primary screen.

  1. Log in to your online Amex portal.
  2. Click on your activity and locate the transaction.
  3. Click on the transaction to open the drop-down details.
  4. Look under Merchant Information. You will see a category (e.g., “Transportation - Lodging”) and a “Category” descriptor.
  5. To get the exact classification, look for the “Appears on statement as” section and check the expanded merchant details, which often list the specific sub-industry.

Citi #

Citi provides solid data for past transactions, though finding the exact numeric code requires a quick export.

  1. Log in to your Citi account online.
  2. Click on your card and go to your transaction history.
  3. Click on the transaction. The expanded view will show you the general category assigned to that merchant.
  4. To see the precise coding, download your transactions into a CSV format. The downloaded file frequently includes more granular category classifications than what is displayed on the main dashboard.

How to Look Up MCCs Before You Buy #

The best way to prevent a missed rewards opportunity is to find the merchant category code before you swipe your card. This is especially important for massive purchases—like booking a wedding venue, paying a contractor, or buying furniture—where thousands of potential points are on the line.

There are three primary methods to look up an MCC before making a purchase.

1. The Visa Merchant Locator Tool #

Visa provides a powerful, free online tool called the Visa Merchant Locator. Because merchants typically maintain the same category classification across payment networks, looking up a business on the Visa database is highly reliable even if you plan to use a Mastercard or Amex.

To use the tool:

  1. Search online for the “Visa Supplier Locator” or “Visa Merchant Locator.”
  2. Enter the business name in the search field.
  3. Provide the merchant’s location (address, city, or zip code) to filter out duplicate names.
  4. Submit the search. The database will return a list of matching merchants along with their exact Merchant Category Code (MCC) and its text description.

This tool is incredibly useful for verifying whether a local specialty food market is coded as a “Grocery Store” or a “Miscellaneous Food Store” (which often does not qualify for grocery rewards).

2. Crowdsourced Databases and AwardWallet #

Because card issuers do not make this information completely seamless to find, the award travel community has built its own solutions. The AwardWallet Lookup Tool is a massive, crowdsourced database where users input their real-world experiences.

You can search for a specific merchant name and location, and the tool will show you how that merchant coded for other users across different payment networks (Visa, Mastercard, Amex, and Discover). This is particularly useful for online-only merchants or digital services where a physical address is not available to plug into the Visa Merchant Locator.

3. The “Test Charge” Strategy #

If you are planning a very large transaction and cannot find the MCC using online tools, you can use the test charge strategy. This is a favorite tactic of advanced credit card rewards maximizers.

  1. Make a tiny purchase at the merchant in question (e.g., buy a $5 gift card, a cup of coffee, or a small accessory).
  2. Wait 24 to 48 hours for the transaction to move from “Pending” to “Posted” in your online account.
  3. Examine the transaction details using the steps outlined in the previous section to see exactly how it coded.
  4. If it triggers the desired bonus category, you can safely proceed with your major purchase.

Why MCCs Differ Across Payment Networks #

It is a common misconception that a business has one universal MCC. In reality, a merchant can be classified differently depending on the payment network (Visa, Mastercard, American Express, or Discover) they are using to process the transaction.

A local bakery might be classified as a “Bakery” (MCC 5462) under the Visa network, which might not qualify for a dining bonus on a Visa card. However, Mastercard might classify that exact same bakery under “Eating Places and Restaurants” (MCC 5812), meaning a Mastercard with a dining bonus would earn full rewards.

Additionally, large retailers that operate multiple departments (like Supertargets, Meijer, or Costco) present unique challenges. A purchase made at a standalone target.com site might code differently than a purchase made in-store. Likewise, buying a gift card at a grocery store register will code as “Grocery,” while buying the exact same gift card directly from the merchant’s website will code under that merchant’s specific category.

Understanding these subtle shifts in network categorization allows you to optimize your credit card setup by matching the right card issuer and payment network to the specific merchants you frequent.

Simplify Your Rewards Tracking #

Manually researching merchant category codes and memorizing which of your credit cards earns the highest rate for each code is a massive mental burden. When you are balancing rotating 5% categories, quarterly limits, and multiple card issuers, it becomes incredibly easy to make a mistake and leave valuable points on the table.

To take the headache out of the process, you can use the Credit Card Central companion app. This secure mobile app allows you to organize all of your cards in one place. Instead of digging through spreadsheet exports or guessing how a store will code, you can easily track your active rewards categories, monitor annual fees, keep tabs on your sign-up bonus minimum spend deadlines, and instantly see which card in your wallet is the absolute best option for any purchase. Because all of your data stays safely on your own device, you get complete peace of mind while maximizing your cash back and points.

Frequently Asked Questions #

Can a merchant change its MCC? #

Yes. A merchant’s MCC can change if they change their merchant credit card processor, restructure their business model, or update their point-of-sale system. If you notice a merchant you frequent is suddenly earning fewer points than usual, they may have recently updated their payment processing setup, resulting in a new MCC.

What should I do if a purchase coded incorrectly? #

If a transaction codes under a category that prevents you from earning your expected bonus points, your options are limited. Card issuers rely strictly on the data sent to them by the merchant processor; they do not manually change transaction codes. However, if it was a very large purchase, you can call the customer service number on the back of your card, explain the situation, and ask politely if they can issue a “goodwill” adjustment of the missing points.

Do mobile wallets like Apple Pay or Google Pay change the MCC? #

No. Using Apple Pay, Google Pay, or Samsung Pay does not alter the underlying merchant category code. The payment tokenization system passes the merchant’s native MCC directly to your credit card issuer, meaning you will still earn your normal category bonus points.

Do online shopping portals change the merchant category code? #

Generally, no. If you use a shopping portal (like Rakuten) to navigate to a store, your credit card is still charged directly by the end merchant, so the MCC remains the same. However, using third-party payment aggregators like PayPal can occasionally mask the original merchant’s identity, resulting in the purchase coding under a generic “Utilities” or “Business Services” category, though major networks have gotten much better at passing through the original merchant’s data in recent years.
