Port Your Business Phone Number to SupaBook | Keep Your Number

Start porting my number or get a new number instead.

How porting your number works

  1. Sign up and choose your plan: create your SupaBook account and pick the plan that includes your number. Your existing number slots in immediately, so no new number is required.
  2. Submit a port request: provide your current carrier's account number, PIN, and the number you want to bring over. SupaBook handles the LOA (Letter of Authorization) and submits the port for you.
  3. Keep using your old number during the transfer: porting typically takes 5 to 10 business days, and your current number stays active the entire time.
  4. Go live on SupaBook: once the port completes, your number is fully live with AI call answering, missed-call text-back, CRM, and everything else on your plan.

What you keep when you port

  • Your existing phone number.
  • Your local area code reputation.
  • All existing contacts who already have your number.
  • Continuity with printed materials, Google Business Profile, and ads.

This is the main reason businesses port rather than start fresh. A number printed on vehicles, signage, business cards, and directory listings carries real value, and changing it means reprinting everything and losing calls from anyone using the old listing.

What you gain after porting

  • AI receptionist that answers every call 24/7.
  • Missed-call text-back to recover lost leads.
  • Every call logged to your CRM automatically.
  • Your personal number stays private.
  • Business texts and voicemail in one inbox.
  • Call routing to your team or to the AI.

Number porting FAQs

What do I need to start a port?

You need your current carrier's account number and PIN or passcode, the billing name and address on the account, and the exact phone number you want to transfer.

What happens to my old plan once the port is done?

Once your number is live on SupaBook you can cancel your old service at any time. We recommend waiting until you have confirmed the number is fully working before cancelling.

Can I port a Google Voice number?

Yes. Google Voice numbers can be ported away. You need to unlock the number in your Google Voice settings first, then submit the port request through SupaBook.
