Their numbers aren't always accepted with various entities. I just tried to register with irs.gov, for example, unsuccessfully.

There are whole blocks of legitimate carriers that aren't accepted with various entities. Last time I tried to make a Facebook account I went so far as to buy a phone and a cell plan to try to get a number that would validate in their system, but they wouldn't budge.

Yup - the numbers Google Voice has are tagged as 'VoIP numbers' in some dataset somewhere and are blacklisted by a fair number of services and blocked from 2FA or Sign-up.

This has also happened to me when using MVNO carriers (Cricket, for example).

I tried to use mine, and it is not recognized as a cellphone number, I imagine as a landline one.

Isn't Google Voice only in the US, though?

How do you log into Google Voice?

It can be set up to forward inbound texts to another number, or you can see them via the app.

I haven't had the "blocked" issues others have, and.. in the case of the IRS, I do have someone who files my paperwork for me.
