The Credit Card Issuers With the Most Complaints in 2026
Federal complaint data shows which credit-card issuers generate the most complaints about how cards are serviced — billing errors, fees, fraud disputes, and payment problems. This is a ranking by total complaint volume, not per customer: no federal count of open card accounts exists to normalise against, so the largest issuers naturally sit near the top (see methodology).
Key finding
Citibank generates the most card-servicing complaints of any US credit-card issuer — 60,185 federal complaints — ahead of Capital One (57,580) and JPMorgan Chase (42,399). These are complaints about billing, fees, fraud, and payment problems; credit-reporting disputes filed under the card product are excluded so the count reflects card servicing, not credit-file errors.
Card-servicing complaints — ranked by total volume
Total federal complaints filed under the credit-card product, with credit-reporting disputes removed. This is an absolute count — higher volume reflects both issuer size and servicing problems, not a per-customer rate.

Is your issuer on this list?
If your card issuer sits near the top of this list, it generates a high absolute volume of card-servicing complaints — billing disputes, fraud cases, and payment problems that consumers escalated to a federal regulator. Switching banks takes about 2 hours of active effort spread across 10 days.
Why the largest issuers dominate the list
The top of this table — Citibank, Capital One, Chase, Synchrony — is largely a map of the biggest card books in the country. A volume ranking measures total complaint load, and more accounts mean more complaints in absolute terms. It is the honest answer available: there is no public, federal count of open card accounts per issuer to divide by, so we do not publish a manufactured per-customer rate.
One name surprises people: Synchrony Financial. Most consumers don't know they bank with Synchrony — it is the largest US issuer of private-label cards, the bank behind the Amazon Store Card, PayPal Credit, and CareCredit. Nearly 40,000 card-servicing complaints make it the fourth-largest source on this list.
What this ranking does — and does not — tell you
A high count means an issuer is a large source of federal card-servicing complaints in absolute terms. It does not mean you are more likely to have a problem than at a smaller issuer — a bank with twice the cardholders can post twice the complaints while treating each customer identically. Read this as total complaint load, not a per-account risk score.

Methodology
Counts come from the CFPB Consumer Complaint Database, credit-card product (data through the May 2026 snapshot). We exclude complaints whose issue is a credit-reporting dispute — investigations, "information on your report," incorrect-information claims — even when filed against a card, so the figure reflects card servicing: billing, fees, fraud, and payment problems. We also exclude credit bureaus and prepaid programs that are not card issuers (Equifax, TransUnion, Experian, Netspend, Chime). The ranking is by total card-service complaint volume, not per customer: no federal count of open card accounts exists to normalise against, so larger issuers rank higher by construction.
