What to do if…
an unfamiliar authorized user appears on your credit account

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Contact the card issuer or lender promptly using the number on the back of your card, the issuer’s app, or its official website. An unfamiliar authorized user may indicate fraud or an issuer error, so ask the issuer to remove the user, secure the account, and review recent activity with you.

Do not do these things

  • Do not ignore the new user or wait several days before contacting the issuer.
  • Do not use a phone number or link from an unexpected message. Use the number on the back of your card, the issuer’s app, or its official website.
  • Do not post screenshots of the account page or share account details publicly.
  • Do not confront someone you suspect while you are still checking whether your accounts or communications are secure.
  • Do not make permanent account changes until the issuer explains the available options, unless you can immediately lock the affected card in the issuer’s app.

What to do now

  1. Contact the issuer or lender through an official route.

    • Tell them that an authorized user you do not recognize has appeared on the account.
    • Ask them to remove the unfamiliar user and cancel any card issued for that user.
    • Ask them to check for recent changes to the account, such as contact details, mailing address, alerts, linked accounts, or replacement-card requests.
    • Ask whether the card number or account credentials should be replaced.

  2. Secure access to the affected account.

    • Use the issuer’s app to lock the affected card if that feature is available.
    • Change the account password using a strong password that you do not use elsewhere.
    • Turn on multi-factor authentication if the issuer offers it.
    • Secure the email account linked to the credit account or used for password recovery.

  3. Review recent activity with the issuer.

    • Check recent transactions, pending transactions, statements, and any newly issued cards.
    • Report any charge or change you did not authorize.
    • Ask the issuer how to submit its fraud or dispute form and whether written follow-up is needed.

  4. Check your credit reports.

    • Use AnnualCreditReport.com to review your reports from Equifax, Experian, and TransUnion.
    • Look for unfamiliar accounts, inquiries, addresses, or name variations.
    • If you find an error, dispute it with the credit reporting company and the company that supplied the information.

  5. Place credit freezes if identity theft may be involved.

    • Contact Equifax, Experian, and TransUnion separately to place a free credit freeze with each bureau.
    • A credit freeze can make it harder for someone to open new credit accounts in your name. It does not remove the unfamiliar user from an existing account.
    • You can also place an initial fraud alert through one bureau while arranging the freezes. The bureau you contact must notify the other two.

  6. Use IdentityTheft.gov if there are signs of identity theft.

    • File a report if you find unfamiliar charges, new accounts, inquiries, or other signs that your information has been misused.
    • Save the recovery plan and keep issuer case numbers, dates, and copies of any documents you submit.

  7. Check for phone-number compromise only if there are warning signs.

    • Contact your mobile carrier if you unexpectedly lose service or receive notices about a SIM change, number transfer, or carrier-account login you did not request.

What can wait

  • You do not need to decide today whether to permanently close the account or move to another lender.
  • You do not need to buy a paid credit-monitoring service before contacting the issuer and placing free credit freezes.
  • You do not need to reset every password at once. Start with the affected credit account and the linked email account.

Important reassurance

You do not need to solve everything at once. Contacting the issuer, securing the affected account, checking recent activity, and reviewing your credit reports are enough for the first safe steps.

Scope note

These are first steps only. Later disputes, documentation requests, account changes, or credit-report corrections may need follow-up with the issuer, the credit reporting companies, or a specialist.

Important note

This is general information, not legal, medical, financial, therapeutic, or other professional advice. Follow the issuer’s instructions for the affected account and use official websites or contact details.
