Facebook accepts email registration, but a phone number quickly becomes unavoidable: fresh accounts are routinely stopped by a checkpoint that demands SMS confirmation before the profile can be used. A virtual number from Get-SMS passes that check without tying the account to your real SIM — important if you keep separate profiles for work, ads, or testing.
Facebook's anti-fraud is aggressive on new accounts. The number itself verifies in seconds, but whether the account survives the first week depends on context: residential IP, believable profile data, gradual activity. An account registered through a datacenter proxy and instantly added to five ad campaigns will be checkpointed no matter what number confirmed it.
Register with a clean IP that matches the number's region when possible — a US number with a US IP looks natural and passes checkpoints more often. Fill in the profile before doing anything else, and don't rush friend requests. If Facebook rejects the code or says the number is in use, cancel it for free and pick another pool; Portugal, Brazil and Philippines are reliable alternatives to the US. For ad accounts that must live long, rent a 30-day number — Facebook periodically re-asks for SMS confirmation on accounts it finds interesting.
The same verified profile also unlocks the rest of Meta's ecosystem: Marketplace listings, a WhatsApp Business link, and Instagram cross-connection all inherit the phone confirmation from the Facebook account. That makes one well-made profile with a verified number noticeably more useful than several throwaway ones.
