Co-Signing a Credit Card: How It Works and the Risks
What co-signing means
A co-signer guarantees the account: if the primary borrower does not pay, the co-signer is legally on the hook for the full balance, and the account appears on both credit reports. It was historically a way to help someone with no credit get approved by backing them with your stronger profile.
Why it is mostly gone
Most major U.S. credit card issuers have stopped allowing co-signers, so it is rarely an option today. Where it does exist (more often with student loans or auto loans), the risk is significant: you are fully responsible for a card you do not control, and their missed payments hit your credit.
Safer ways to help
The modern alternative is adding the person as an authorized user on your card. They get a card and can build credit from your account history, while you keep control and they are not liable for the debt, though you are responsible for their charges. For their own credit, point them to a secured card and how to build credit.
