Get a WhatsApp Business Number Without a Second Phone

WhatsApp Business is powerful — but using your personal number is messy

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.

How it works

Five straightforward steps to get a separate business WhatsApp Business phone number.

Choose your CallCenturion number

Sign up and select a UK virtual number for WhatsApp Business. No SIM or extra handset required.

Enable Direct Redirect in CallCenturion

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.

Enter your CallCenturion number in WhatsApp Business

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.

Switch back to AI Receptionist mode

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.

Start using WhatsApp Business with a separate number

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.
