How do I check if my number was registered on AIS?

Check to see if your SIM card is already registered.

To check the registration status of your SIM card, dial *161# (free). The SMS response will show the last 4 digits of the personal identity 13 digit number or passport number.
  • If your SIM card is unregistered, please bring the SIM2FLY card and your personal identification or passport to any AIS Shop (including Airport branches) or Telewiz to register your SIM card.
