Defined terms

Virtual number
A virtual number is a phone number used through a provider rather than a personal SIM contract, often obtained briefly to receive calls or SMS messages.
Non-VoIP number
A non-VoIP number is a mobile number issued from a carrier's mobile range, not from an internet telephony range, and is often accepted for SMS verification.
Verification code
A verification code is a short one-time code sent by SMS or call to confirm that a person controls a phone number during sign-up or login.
Two-step verification
Two-step verification is an optional WhatsApp setting that adds a PIN you choose, which the app requests when the number is registered again.
WhatsApp Business app
The WhatsApp Business app is a separate app from WhatsApp, designed for small businesses, that registers with its own phone number and offers business profile tools.
Number recycling
Number recycling is the practice of reassigning a phone number to a new user after the previous user stops using it or after it expires.
