There can be a number of reasons why you are not receiving the authentication code.

  1. Check that the phone number you entered is correct.
  2. Ensure the phone number is 10 digits. Do not include the country code; it's already selected in the prior field.
  3.  Make sure you have a cellular signal.
  4. Confirm SMS messages are not getting blocked.  SMS rate limits are rare but still do happen.
  5. Try another method.  If you chose to receive a text the first time, try the voice option instead or vice versa.
  6. If email is selected as the method, ensure that the authentication code isn't going to your spam or junk folder.
  7. Check to ensure you have a stable internet connection.
  8. If you have requested too many codes in one day, you will be limited to seeing just one code an hour.  Wait one hour and try again.
  9. If you are in one of the following locations, you will not be able to receive a code by text or voice call:
