Start here
The transfer starts inside KaiCalls.
If you already have a KaiCalls business account, open Number Porting and enter the business line you want to keep. If you are signed out, we will bring you back to the same page after login.
Ready to move the number?
Click below, choose Port a Number, and KaiCalls will check the number before you complete the rest of the request.
Before you begin
Use the current carrier's records, not your best guess.
The legal name, account number, PIN, and address must match the carrier account. A mismatch is the most common reason a request is rejected.
The number
Have your business number ready. Check if it handles calls, customer texts, or building alarms today.
The carrier account
Use your recent bill for the exact legal name, address, account number, and transfer PIN.
The authorized signer
The person on the bill must approve the transfer before KaiCalls submits it.
Keep your current account active and paid. Do not cancel service or change lines while the move is open.
The customer flow
From number check to accepted cutover
- 1
Enter your number
Open Number Porting, click Port a Number, and enter your office line. KaiCalls checks if it is eligible right away. - 2
Tell us how the line is used
Tell us if customers text it or if alarms run on it. A personal cell is not moved. - 3
Confirm the account details
Copy the exact name, address, account number, and port PIN from your latest bill. - 4
Choose a date and authorize
Pick your preferred switch day. The authorized signer approves the form. The date is final once the carrier confirms it. - 5
Track, switch, and test
KaiCalls shows live progress. When the line moves, run test calls to verify Kai answers before you accept.
While it moves
The Number Porting page is your status screen.
Submitted or pending
The request is with the carrier. Keep your old service active. Use your temporary KaiCalls line to test your call flow.
Carrier date confirmed
The carrier locked in the switch date. KaiCalls uses that date for cutover.
Needs correction
Check the rejection note against your bill, update the wrong field, and resubmit.
Carrier complete
The number has moved to KaiCalls. Run your test calls and accept the cutover.
Switch day
Accept the cutover only after the real number works.
- Call the moved number from a mobile phone and verify Kai answers.
- Place a test call out and verify the business caller ID shows.
- Test greetings, voicemail, and after-hours rules.
- Check that the call log and alert text arrive on your cell phone.
- Accept the cutover in KaiCalls only after these tests pass.
Know what is moving
Voice, texting, fax, and specialty hardware.
Porting moves your business number onto KaiCalls for voice calls. Customer texting (SMS) requires separate brand registration before messages can flow. A personal cell is never moved — it stays yours and forwards to Kai when unanswered. Specialty hardware like physical fax machines, alarm panels, elevators, or door buzzers should not be moved to an AI phone system.
Troubleshooting
The usual reasons a transfer pauses
The number is not eligible
Confirm you entered an office line in the United States or Canada. A personal cell and some toll-free or specialty numbers need a different plan.
The carrier rejected the details
Use a recent bill or Customer Service Record. Match the legal name, service address, account number, PIN, and billing telephone number exactly, then resubmit the existing request.
The requested date changed
The requested date is a preference. Use the carrier-confirmed date shown in KaiCalls for staffing, testing, and customer communication.
The carrier says complete, but calls fail
Do not accept or cancel the old service. Report the failed customer path to KaiCalls and use the agreed fallback while routing and provider evidence are checked.
How long does a number transfer take?
Most business-number transfers take about one to three weeks after the account details are correct. The requested date is not final until the carrier confirms it. Toll-free and complex multi-number transfers can take longer.
Should I cancel my current phone service first?
No. Keep the current account active and paid until KaiCalls confirms the transfer is complete, your live tests pass, and it is safe to cancel the replaced service.
Can I move a number that customers text or fax?
Voice calls transfer with the number. Texting requires separate brand registration before messages can flow. Analog fax machines, alarm panels, and building lines should stay on dedicated lines.
What happens if the carrier rejects the request?
The most common cause is an account-detail mismatch. Use a current bill or Customer Service Record to correct the existing request, then resubmit it from KaiCalls.
