Frequently Asked Questions

How long do public messages remain visible?

Public SMS messages are displayed in real-time and remain visible in the message stream for 48 hours before automated purge.

Can other users see my incoming verification codes on free numbers?

Yes. Free numbers are public community lines. If you are verifying sensitive accounts like banking or private social accounts, we strongly recommend renting a private dedicated SIM line.

How quickly do SMS messages arrive?

Messages typically appear in the live feed within 2 to 10 seconds after being sent by the verification provider.

Do these numbers work with WhatsApp and Telegram?

Yes! Our numbers use authentic cellular carrier routing rather than blocked VoIP lines, allowing high delivery success rates for popular messaging apps.
