Is there any chance my cellphone number is a VOIP-routable nubmer? Is there a way I can check to find out?

Twilio has a (US-only) API for this: https://www.twilio.com/docs/lookup/tutorials/carrier-and-cal...

Im not sure what banks use, but I have had UK VOIP numbers flagged before when trying to register them for 2FA, so theres likely API providers for other countries.
