Shannon Wink and her husband aren’t looking for a fancy credit card. They just want solid rewards, an easy-to-use online interface and one must-have feature that they can’t seem to find.

They want to be joint account holders, the same way they could with a checking or savings account. But while some card issuers offer the functional equivalent of a joint account, they don’t call it that. That leads to confusion for potential customers like the Winks.

The Winks are looking for an account that gives them equal status and responsibility. Neither of them wants to be reduced to authorized user status on the other’s credit card accounts, and they don’t want one spouse to have to “co-sign” for the other.

“We’re looking for something that holds us both accountable,” says Wink, managing editor of Billy Penn, a Philadelphia news website. “We don’t want one of us to either reap the credit benefits or get saddled with all the debt.”

There are several ways two people can share a credit card account:

In all important ways, co-signers and joint account holders are essentially the same.

“I view them synonymously,” says Jerry Young, Discover’s director of acquisition marketing.

Both co-signers and joint account holders are “jointly responsible for the repayment of an account, versus an authorized user who isn’t legally responsible for the debt,” Young says.

However, the definitions of joint account holder and co-signer may vary from issuer to issuer. Some issuers might define the two roles differently, allowing greater account access to joint account holders than they would to co-signers.

It’s important to Wink that both she and her husband be able to make changes to their shared accounts. They’ve run into trouble elsewhere, such as the workplace insurance plan that won’t talk to Wink directly because her husband is the primary policyholder.

“I can’t add him to my Verizon account,” Wink says. “Nothing is really shared.”

Wink and her husband are joint account holders on a credit card from PNC Bank. They’d like to find another credit card with a better online interface and higher rewards, but none of the issuers they’ve found offer joint status.

Even if you go with a bank that allows credit card co-signers, the options are fairly limited. (See a list here.) Big banks that offer traditional banking services along with credit cards may be more likely to allow co-signer status, perhaps because joint account holders are more common on checking or savings accounts than they are on credit cards.

If equal account access is a make-or-break feature when you’re shopping for a new credit card, ask the issuer to explain what each person’s rights and responsibilities will be, whether you’re joint account holders or co-signers. Just like the relationship between you and your partner, the relationship you have with your financial institution is stronger when it’s built on good communication.
