Activating your Regular or International ATH through Internet Banking

To assign a secret number to your regular or international ATH card you must:

  • Have enrolled at Internet Banking.
  • Have a new ATH card that has not been validated.

If you meet the previous requirements, do the following:

  1. Log in to Internet Banking.
  2. Choose the Account Services option on the left side.
  3. Choose Activate ATH Card option.
  4. Fill in the following spaces: card number, new PIN and confirm new PIN. (PIN is your secret number.) Click Send.

    If the activation process is completed correctly, Internet Banking will show you a message telling you that your card was successfully activated.

    If, on the contrary, the system tells you that the activation could not be completed, it may be for the following reasons: your card may already have an assigned PIN (you can't change PIN numbers of active cards through My Online Bank) or the registration has been made with the personal information of another signer and not yours. In these cases, you must visit a branch to receive assistance for our bank officers to complete the activation or change the PIN of any of your ATH cards.
