Submit corrections, suggestions, or topic requests. Please do not send account details, card numbers, SSNs, or PINs — we cannot help with account actions and will never ask for that information.

For account help, contact Capital One

This is an independent knowledge base. For all account actions — activation issues, lost or stolen cards, fraud reports, transaction disputes — you must contact Capital One directly via capitalone.com, the official Capital One Mobile app, or the toll-free number on the back of your card.
