Set up a separate number for WhatsApp Business, receive verification codes, and keep your personal mobile number private.
Many small businesses use WhatsApp to talk to customers, but giving out a personal mobile number can blur the line between work and private life. CallCenturion gives you a dedicated business WhatsApp number that can be used when setting up WhatsApp Business, helping you keep customer communication separate.
Five straightforward steps to get a separate business WhatsApp Business phone number.
Sign up and select a UK virtual number for WhatsApp Business. No SIM or extra handset required.
In your CallCenturion settings, switch your number to Direct Redirect mode. This forwards all incoming calls straight to your mobile with no screening — so you can receive the WhatsApp verification call directly.
Open the WhatsApp Business app, enter your CallCenturion number as your business phone number, and choose “Call me” when prompted for verification. WhatsApp will call your CallCenturion number, which rings straight through to your mobile. Answer it and listen for the 6-digit code, then enter it in WhatsApp.
Once verified, go back into CallCenturion settings and re-enable your AI receptionist for normal call handling. Your WhatsApp Business account stays permanently registered to your CallCenturion number — Direct Redirect is only needed during the one-time setup.
Your personal number stays private. Customers contact your dedicated business WhatsApp number instead.
Verification requires enabling Direct Redirect mode temporarily during setup. Eligibility may depend on WhatsApp/Meta verification rules.
