SupaBook lets you bring your existing business phone number with you. You keep the number your customers already know, and it arrives with AI call answering, missed-call text-back, and automatic CRM logging. Porting typically takes 5 to 10 business days with no downtime.
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.
Most ports complete within 5 to 10 business days. During that time your number stays active with your current carrier, so there is zero downtime.
No. Your number remains live with your current carrier until the moment porting completes. The cutover happens automatically with no interruption.
SupaBook supports porting most US local numbers and toll-free numbers. VoIP numbers from other providers can typically be ported as well. Contact support if you are unsure about your specific number.
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.
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.
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.
