What’s the difference between a credit card network and issuer?

When we discuss credit cards at TPG, we usually focus on the bank that issues the card or the type of rewards the card accumulates rather than which network it belongs to. Still, your card network matters a lot. It can affect everything from where your card is accepted to some of the benefits you receive.

Today, we’ll examine the difference between a credit card issuer and a card network and take a look at the four biggest networks in the U.S.

What’s the difference between a card issuer and a network?

The easiest way to explain this difference is with an example. Let’s say you have Chase’s World of Hyatt Credit Card, and you use it to pay for dinner at a restaurant. In this case:

• The issuing bank is Chase.
• The card network is Visa.
• The merchant is the restaurant.
• The cobrand partner is World of Hyatt.

That’s why most credit cards have two or three different logos on them, representing the issuing bank (Chase), the card network (Visa) and the cobrand partner if there is one (in this case, World of Hyatt).

But what exactly is the functional difference between card issuers and card networks? Mostly it boils down to a division of labor. Each party is responsible for different jobs that keep your credit card working.

Card issuers such as Chase do the following jobs:

• Handling and evaluating credit card applications.
• Producing and distributing the physical cards.
• Creating the terms and benefits of the account, including things like interest rate, annual fees and bonus categories. (For cobranded cards like this example, the cobrand partner — here it’s World of Hyatt — often helps negotiate the terms and benefits).
• Paying merchants on behalf of the cardholder (i.e., paying the restaurant when you swipe your card).
• Collecting payments from cardholders and providing account services.

Meanwhile, the primary functions of a card network (Visa in our example) include setting the interchange fees (commonly known as swipe fees) and building out a payment infrastructure so more merchants can accept their cards.

If you’ve ever been to a store that accepts Visa cards as payment, the cashier won’t stop and ask whether Chase or Bank of America issued your Visa because any card on the Visa network should work for them.

The four major card networks

Four major credit card networks in the U.S. account for an overwhelming majority of the market:

• American Express
• Discover
• Mastercard
• Visa

While Visa and Mastercard partner with several different issuing banks, American Express and Discover issue their own cards, allowing them to play both roles. Because interchange fees come directly out of the profit a store makes on each transaction, some retailers around the world won’t accept cards from certain issuers because of the higher fees involved.

Historically, Amex has lagged behind Visa and Mastercard in acceptance because of the higher interchange fees it charged, but they’ve been working aggressively to close that gap in recent years.

Credit card issuers decide many of the specific benefits of the cards they offer, but they’ll often partner with the card network to adopt a preset service level.

Does it matter which card network you use?

For most people, the card network is an afterthought. They pick a credit card based on the welcome bonus and benefits package that matters most to them, not whether it’s a Visa, Amex, Mastercard or Discover. It’s hard to say that one network is better than the others for a customer, but it’s important to diversify your wallet.

A few years ago, Visa suffered a major network outage that blocked all its credit cards from being used across Europe. Since this was an issue with the network, it didn’t matter whether you had a Visa issued by Chase or Capital One — all Visa cards were affected equally. Ever since then, I have made it a point to carry cards from at least two different networks (usually Visa and Amex) at all times in case something similar happens.

The other point you’ll want to consider is merchant acceptance. You’re bound to run into individual merchants, both in the U.S. and internationally, that won’t accept an Amex, Discover, Mastercard or Visa. Holding cards from multiple networks in your wallet is a great way to make sure you’ll have credit when you want it.

Another thing to note is that certain card benefits are tied directly to the network. For example, some Visa cards are designated as Visa Signature cards, while some Mastercards are designated as World Elite Mastercards. These cards offer guaranteed benefits determined by their respective network.

There are a number of popular Visa Signature cards on the market, including the Chase Sapphire Preferred® Card and the Alaska Airlines Visa Signature® credit card. Although these cards all accrue different types of points and miles and offer different bonus categories and interest rates, they all share a number of common benefits as Visa Signature cards, including extended warranty protection, travel and emergency assistance and access to the Visa Signature concierge service.

Similarly, World Elite Mastercards, such as the Citi Strata Premier℠ Card (see rates and fees), the IHG One Rewards Premier Credit Card and the Citi® / AAdvantage® Executive World Elite Mastercard® (see rates and fees), offer specific additional benefits.

Bottom line

Credit card networks provide the infrastructure that keeps our cards functioning. But because they don’t directly issue rewards (with the exception of Amex and Discover, which are both networks and card issuers), it’s easy to overlook their importance.

If you haven’t yet, spend some time going through your wallet and making sure you have a diverse collection of cards from multiple issuers and multiple networks, just in case.
