FAQ/Why isn't my number being accepted by an online service?

Context: https://blog.jmp.chat/b/2022-sms-account-verification

Some companies maintain secret lists of phone numbers which they prohibit for new signups. If you run into this problem, you can:

try again (sometimes this solves the issue)
contact the company, letting them know of the issue
use a different form of 2FA, like OTP (since SMS 2FA is neither private, nor is it all that secure
find an alternative to that company's services
use a service specifically tailored to SMS verification instead, like https://crypton.sh/ or https://juicysms.com/ (their numbers might not be on these block lists, but they lack certain other features of a JMP phone number)

Sample of services with successes and failures:
