How to move your number from Zoom Phone
Zoom Phone business numbers. An account admin finds the account number and the port-out PIN in the Zoom web portal.
What you'll need from Zoom Phone
- Account number
- In the Zoom web portal, under Account Management, then Account Profile. The company name and address to use are under Billing, then Billing Contact.
- PIN
- The port-out PIN in Zoom Phone's Port-out Verification settings. You can set a new one if the current PIN doesn't work.
- Name and address
- Exactly as Zoom Phone has them on your account. Copy them from a recent bill.
- A recent bill
- A PDF or a photo from the last 30 days.
Get your PIN
- Sign in to the Zoom web portal as an account admin.
- Open Phone System Management, then Company Info, then Account Settings, and find Port-out Verification. Click Change to see or set the PIN.
- On some portal versions it's under Number Management, then Phone Numbers, then Related Features.
Good to know
- Zoom doesn't provide a customer service record for port-outs; the account number and PIN are what carriers check.
- Move only the numbers you list. Users, call queues, and auto receptionists stay in Zoom; set up the call handling again here.
- Keep your Zoom Phone service until the move is done, or the number can be lost.
Then move it to Onyx Phone
- Start your free trial. You get a temporary local number right away, so you can make and take calls today.
- Forward your current number to the temporary one if you like (most landlines: dial *72 and the number), so customers reach you here during the move.
- In Onyx Phone, open Lines, then Begin a port, enter the details above, and attach the bill. Moving a number is free on every plan.
- Sign the letter of authorization we email you. Nothing starts until it's signed.
- The carriers confirm a date, usually 3 to 7 business days after you sign. On port day your number replaces the temporary one, and calls you place show it.
- The temporary number keeps ringing your line for 30 more days, so anyone you gave it to still gets through, then it's released.
Texting registration doesn't come with the number. US carriers approve each business that texts, so register in Onyx Phone when you start the move; approval usually takes one to two weeks, and calling works meanwhile.

Questions about moving from Zoom Phone
How long does it take to move a number from Zoom Phone?
Usually 3 to 7 business days after you sign the letter of authorization. Zoom Phone and Onyx Phone's carrier confirm the date, and you get an email at each step.
Will my phone stop working while the number moves?
No. Keep your Zoom Phone service until the move is done. You answer on a temporary Onyx Phone number in the meantime, and you can forward your current number to it so customers reach you either way.
Does moving my number cost anything?
Moving it to Onyx Phone is free on every plan.
Can I text from the number as soon as it moves?
Texting registration doesn't come with the number. US carriers approve each business that texts, so register in Onyx Phone when you start the move; approval usually takes one to two weeks, and calling works meanwhile.
What if Zoom Phone turns the move down?
Onyx Phone shows what the carrier said, and you can fix the details and send it again. The usual reasons: the account number, name, or address doesn't match what the carrier has. Copy them from a recent bill; the PIN expired or was replaced. Get a new one and send the request again.
Can I move a toll-free number?
Not from the app yet. Guides cover US local and mobile numbers. For a toll-free number, tell us on the contact form and we'll arrange it.
