The most common question is "will this number work for my platform?" The answer depends on how strict the platform is. This matrix matches common platforms to the number type that actually passes, based on how each platform is known to filter.
How to read it
Physical (real SIM) numbers pass almost everywhere. VoIP/virtual numbers only pass on lenient platforms. When in doubt, or when the account matters, go physical.
| Platform | VoIP tolerance | Use |
|---|---|---|
| Low | Physical | |
| Telegram | Low | Physical |
| OpenAI / ChatGPT | Low | Physical |
| Discord | Low | Physical |
| Snapchat | Low | Physical |
| Apple ID 2FA | Low | Physical |
| Binance / Coinbase | Low | Physical |
| Google / Gmail | Medium | Physical, match country |
| Medium | Physical, match region | |
| PayPal | Medium | Physical, match country |
| Lenient / older services | Higher | VoIP often fine |
The simple rule
If the platform is a messaging app, fintech, or an AI service, assume it blocks VoIP and use a physical number. If it is an older or more lenient service, a cheaper number usually delivers.
When the account matters, always physical
A number that fails does not just waste the fee — it can leave you mid-signup with a flagged attempt. For any account you intend to keep, the few extra cents for a physical number are the cheapest insurance available.
Match country where it matters
Google, PayPal, and Facebook cross-check the number’s country against the account. Even a good physical number can fail if the region does not fit. Use a number whose country matches the account.
