Troubleshooting

  • Don’t see the card? Brand-new cards/accounts can take time to appear. Try signing out/in or ensuring the card is linked to your username.
  • No verification code? Check spam/blocked messages and confirm your phone/email on file, then request a new code.
  • Replacement card? After activation, update any saved payment methods. Dispose of plastic cards by cutting through the chip; return metal cards in the provided envelope.

Type URLs directly (avoid unexpected links), never share one-time passcodes, and use 2-step verification in your Capital One profile. Only use the official website or app.
