Why Facebook and Instagram Block Virtual Numbers (and How to Avoid It)

The problem: Facebook blocks virtual numbers

If you've tried to verify a Facebook or Instagram account with a virtual number, you may have seen:

> "We don't allow this phone number. Please use a different one."

Why does this happen? Let's break it down.

How Meta detects virtual numbers

Meta (the company behind Facebook, Instagram, WhatsApp) maintains a dynamic blocklist of number ranges known to be:

• VOIP-only (e.g., Twilio, Google Voice).
• Public, free, or shared between many users.
• Used in bulk registration abuse.
• Recently released and re-used by spammers.

When you request an SMS code, Meta checks the number's reputation and rejects low-trust ranges.

The solution: real, non-VOIP numbers

The single biggest factor in passing Meta's check is using a real, SIM-based mobile number that has a positive reputation. RCVSMS exclusively uses real SIMs in 150+ countries — not VOIP.

5 tips to avoid being blocked

1. Choose countries with high success rates (US, UK, Germany).
2. Don't reuse numbers across many accounts on the same device.
3. Use a daily rental instead of one-shot SMS for important accounts.
4. Avoid free public numbers — they are flagged within hours.
5. Match the country to your IP when signing up, where possible.
