Some internet services use “short codes" for their mass messaging services for verification codes, one-time passwords (OTP), two-factor authentication (2FA), coupon codes, etc.
Although MySudo does accept messages from short codes, some services, by design, do not accept VoIP phone numbers.
A few workaround options if you experience this issue:
- If you are using a UK MySudo phone number, try using a US or CAN number
- If your website/app has the option to verify via email
- If your website/app has the option to verify via phone call
- Use your personal phone number to get verified, then change your phone number in their settings to your Sudo phone number. You just won't be able to use Sudo for verification texts at this time.
As services change their policies and technology, more short codes from those services will be received.
*Please note that you may not be able to reply to short code numbers in all cases from MySudo.
