If you are interested in porting your Zoom phone number(s) to OnSIP, please have your Zoom account admin sign in to the Zoom web portal and navigate to the Port-out Verification section to obtain the required port-out PIN.

You can provide the Zoom account # and the port-out PIN to OnSIP when submitting your port request, or when returning your signed LOA (authorization) form. 

The Address and Company Name required to port your number(s) can be found in the Zoom web portal. Select Account Management > Billing in the navigation menu to locate the Billing Contact section where the Company Name and Address will be listed.

In place of a traditional bill copy, you can supply OnSIP with screenshots from your Zoom web portal showing the phone numbers to be ported, the name and the address on the account. The number you are porting out can be used the BTN (Billing telephone number).

* If Zoom rejects your port out request because the number to be ported is listed as a PSAP number, you will need to update your Zoom PSAP number to one that is not porting. Once that has been done, please ask OnSIP to resubmit the port request.

Note: We make every attempt to work with all telephone service providers. However, certain local or regional guidelines may preclude your current provider from releasing your number.
