Can I use Burner to sign up for websites?
VoIP Verification is when you use use an online numbers (which is what Burner is) to sign up for 3rd party websites.
Burners are all set up to accept interactions with short-codes and verification systems (such as these 3rd party sites), so as long as the other party doesn't have any issues with VoIP numbers, you should be good to go. Keep in mind that 3rd party websites are always updating their platform policy and may not accept online numbers.
If your number doesn't work with your preferred third party service, send us a message at firstname.lastname@example.org. Although there is no guarantee, we'll be happy to try and replace the number for you to see if that helps.
