alt Hacker NewsIf you port your cell number to a VOIP carrier, I don’t think senders have any way of telling that it’s not still a regular cell number?
I have such a ported number and have no issues receiving SMS 2FA codes.

Unfortunately there are a lot of "is this number voip" services that use various tricks to detect voip numbers, or simply buy this data from the voip provider or someone else in the path.
If nothing else, if a particular voip provider only does voip, you can just put them on a blacklist. You can get any number's provider from the number portability clearinghouse (this might be country dependent, where I live, there's only one, and anyone can query it).
