Rules in force

If that fails, escalate

Go up one step at a time. Keep the reference numbers and dates from each contact.

  1. Customer service

    PhoneCiti credit cards, report a lost or stolen card or unauthorized use +1-800-950-5114 Account holder only

    Or the number on the back of the card; per-card numbers are listed below.

  2. Written complaint

    EmailForward suspicious emails and texts claiming to be Citi spoof@citi.com

    Write to the billing inquiries and correspondence address shown on the front of your statement.

  3. Federal regulator

  4. State agency

    Your state’s financial regulator. Find it in the list of state agencies (also as JSON: states/<code>.json, for example states/ny.json).

  5. Arbitration

    Citi card agreements let either party choose AAA arbitration; individual claims in small claims court are not subject to arbitration.

Watch out

  • Citi's contact, dispute and security pages render only with JavaScript; no consumer complaint channel or dispute page was confirmed.
  • The billing-error mailing address is printed on each statement, not in the public agreement.
  • Online disputes and secure messages need sign-in.
