Credit card companies are the banks and credit unions that issue credit cards to consumers and small business owners. Credit card companies also service cardholders’ accounts by billing for purchases, accepting payments, distributing rewards and more.
The four major card networks – Visa, Mastercard, American Express and Discover – are credit card companies, too, though Visa and Mastercard don’t issue their own cards. They handle things like payment processing and high-level benefits.

Credit Card Issuers
Credit cards are usually issued by banks and credit unions. They give these financial institutions a fairly steady source of revenue from account fees, interest charges and payment processing fees charged to merchants. The transactional nature of credit cards also gives issuers a chance to establish relationships with consumers. That allows them to upsell cardholders to other products and services.
Credit card issuers handle things like:
- Processing applications
- Mailing out cards
- Setting interest rates and fees
- Setting credit limits
- Providing rewards
- Providing some benefits
- Customer service
- Reporting account history to the credit bureaus
The heart of a credit card company is its underwriting team. Underwriters evaluate applicants’ credit history, income and debt load to determine whether their risk and profit potential qualify them to get a credit card. The terms a credit card company offers to customers and its ability to turn a profit depend on how sophisticated its underwriting is and how well it can avoid uncollectible debt. Basically, if a credit card company approves people who pay their bills, it can better afford to provide rewards and benefits in return.
The following chart will show you which companies are the biggest players in the credit card game. You can also check out WalletHub’s Statistics Center for a more detailed look at the credit card landscape.

Other Credit Card Issuers
Although the biggest credit card issuers are all national banks, credit unions and regional banks issue tons of credit cards as well.
Some of the best credit unions to get a credit card from include Navy Federal Credit Union, PenFed Credit Union, Alliant Credit Union and General Electric Credit Union. Some advantages that credit unions provide over big banks include a more personalized relationship with their customers and fairly low interest rate caps under federal and state law.
Offers from regional banks are also worth exploring. You can use WalletHub’s bank comparison tool to see the banks that are available in your area, the products they offer and their user reviews.
Credit Card Networks
The four major credit card networks are Mastercard, Visa, American Express and Discover. Mastercard and Visa once held a significant lead in terms of acceptance, but American Express and Discover have made considerable progress over time.
Things that credit card networks handle include:
- The worldwide processing of credit card transactions, acting as a gateway between consumers, merchants and credit card companies
- Setting terms for credit card transactions (e.g., interchange fee & fraud liability)
- Providing certain high-level benefits, such as travel insurance, rental car insurance, purchase protection and extended warranties on purchases
While the major credit card networks all perform a similar function, there are some important differences between them. As you can see from the graphic below, there is a clear hierarchy based on the purchase volume that each handles.

Visa, Mastercard, Discover and American Express also differ in terms of where they can be used – both in the U.S. and abroad. The benefits they provide have earned varying grades in WalletHub’s research, too.
Major Credit Card Networks Compared
Card Network | VISA | MASTERCARD | DISCOVER | AMERICAN EXPRESS |
---|---|---|---|---|
U.S. Acceptance | 10.7 million merchants | 10.7 million merchants | 10.64 million merchants | 10.6 million merchants |
International Acceptance | 200+ countries | 210+ countries | 200+ countries | 198+ countries |
Fraud Protection | Good | Good | Excellent | Excellent |

It’s also important to reiterate that American Express and Discover aren’t just card networks. They’re credit card issuers, too. So if you have a problem with your Discover bill, for example, you can contact Discover directly. But if you have a problem with your Visa bill, you’ll have to contact the card’s issuer – Capital One, for instance.
Credit Card Issuer vs. Network
A credit card issuer is the bank or credit union that issues a credit card, sets its terms and features, and services the account. Examples include Bank of America, Capital One, Citi, Wells Fargo and more.
Credit card networks play a different role. They dictate where credit cards can be used, facilitate payment processing at the point of sale and administer secondary credit card benefits, such as rental car insurance, travel insurance and extended warranties.
The four major card networks are Visa, Mastercard, American Express and Discover. The tricky part is that two of the world’s largest card networks – American Express and Discover – also issue credit cards.
If you aren’t sure which company issued your credit card, check the plastic. The issuer’s name typically appears in big fancy lettering on the front of the card, in the top right or left corner. You'll also find it on the back, at the bottom of the card. Below, you can see an illustration.
This won’t necessarily be the case with store credit cards or co-branded cards, however. The name of the retailer or organization they’re associated with tends to be displayed most prominently. The issuer’s name will be on the card somewhere, but it may be more difficult to locate than with a normal credit card.
In addition, co-branded cards will bear the logo of the credit card they’re associated with and can be used anywhere that network is accepted. On the other hand, store credit cards are not on a credit card network since they can only be used at the partnered merchant, so they will not have a network logo.
It’s important to understand which credit card company issued your card as well as which network it’s on. The former will tell you whom to call if you have a question about your account. And the latter will tell you where you can use your card, plus whether you get perks like:
- $0 fraud liability
- Rental car insurance
- Travel insurance
- Extended warranties
- Purchase protection
- Return protection
- Price protection
It’s also worth noting that while credit card networks provide many benefits, the credit card’s issuer ultimately decides which benefits your card will actually include.

In addition to its credit card operation, Bank of America offers deposit accounts, investment vehicles, and financial management services to consumers. The company also has corporate and investment banking divisions.
Bank of America was founded in San Francisco in 1904. But it actually started out as Bank of Italy, in an attempt to serve the needs of America’s growing immigrant population. It was renamed in 1930, and the company’s continued expansion eventually led to the first ever general-use credit card, known as the BankAmericard. That product later became the basis for Visa.
Bank of America has since made numerous acquisitions. This includes its crucial all-stock purchase of Merrill Lynch at the Federal Reserve’s urging during the Great Recession. Like many other large financial institutions, BofA has also come under fire for various alleged wrongdoing during the downturn and beyond. But the credit card market is a much safer place these days. And Bank of America has actually been a leader in bringing consumer credit card protections to business credit cards.

Bottom Line
There are a lot of credit card companies out there, and finding the best one can be pretty daunting since there are so many factors to consider. That’s why it’s helpful to look at reviews on sites like WalletHub to see what other people’s experiences have been like.
At the issuer level, the most important thing you should worry about is how good the bank’s or credit union’s customer service is. At the network-level, you should consider where the card will be accepted, especially if you travel a lot.
For other terms, like rates, fees, rewards, credit limits, and more, it’s better to look at individual cards, since they differ greatly even within an individual issuer’s offerings.
