Transfer Numbers – User Guide

1.  FAQ

What is transfer numbers?

Transfer numbers is a way to submit requests to transfer (port out) your existing phone number from your old carrier so you can continue using it with service.

This video explains the process.

What do I need to transfer my phone number?

The process begins when the form is completed which includes steps from verifying that the number is portable, LoA (Letter of Authorization) specifying the old carrier, name, address and a good contact number. Before you transfer your number to, please also check the following:

  1. Make sure your phone number is active.
    If you call the number, does it ring? If your number isn’t active, the number transfer will be rejected.
  2. Check your phone contract for obligations.
    Do you have an outstanding balance? Are there any freezes or holds on your account? If so, have those released. We also suggest checking that your number can be transferred. If you got the number from your provider’s inventory, they may not let you port it away.
  3. Name or address mismatch.
    When submits the transfer request to your current provider, they will match the contact information you’ve given us against their records. If the information doesn’t match, they may reject it. Your best bet is to reach out to your provider to verify the exact name and address they have on file for your phone number.
  4. Check for pending orders.
    With some providers, if we submit a transfer request for a phone number that has any kind of “pending order” on it, they may reject the transfer until that issue is resolved. A pending order could be something as simple as updating your mailing address, or something more complex like pending configuration changes to your service.

We do our best to help you resolve issues as we go along, but if you want to save time and effort, we suggest checking off these items before trying to transfer your number.

How can I keep track of my number transfer?

While the number is being ported you can track your transfer request status on Configure > Numbers > Transfer requests tab.  You will also receive an email when the number transfer is complete.

Will I be able to use my number while it’s being transferred?

During the porting period we provide you with a temporary phone number that can be used in lieu of the actual number. This number will eventually clear out of the account as soon as the port out order is complete. 

How long does it take to transfer my number?

Transferring a phone number can take anywhere between 7-10 business days, although in some cases the porting process can take up to 4 weeks. 

Are there any costs associated with transferring my number?

The porting process is free of cost and simply requires your authorization. 

How to configure my temporary number?

Temporary numbers are configured the same way other numbers are, to learn how visit the How to configure a phone number section.

What happens with my temporary number if my porting request is denied?

The temporary number remains on your account until you cancel the porting request. 

What happens with my temporary number if my porting request is completed?

The temporary number will automatically drop from the account so you can begin using your permanent phone number.

How can I port out my number to another carrier?

Similar to porting in porting out must be initiated from the winning-carrier side. This means you must submit the request with the service provider you have chosen to get service from. If there are any requests not mentioned in the FAQ section above please contact our porting team by calling 800.998.7087 or emailing [email protected]

Can I save the draft in the transfer wizard and finish my submission later?
