Transfer phone numbers to Office 365
It's easy to transfer your phone numbers from your current service provider to Microsoft Teams. After you port your phone numbers to Teams, Microsoft will become your service provider and will bill you for those phone numbers.
Before you start transferring phone numbers, we recommend that you review the information in Transferring phone numbers common questions. If you have service numbers for dial-in conferencing bridges, auto attendants or other service numbers, toll-free phone numbers, or have more than 999 user (subscriber) phone numbers that you need to transfer to Teams, see Manage phone numbers for your organization to download the correct forms and send them to us.
We process port orders for transferring phone numbers only on U.S. business days and not on public holidays or weekends.
How to create a port order and transfer your phone numbers to Teams
If you have service numbers for dial-in conferencing bridges, auto attendants or other service numbers, toll-free phone numbers or have more than 999 user (subscriber) phone numbers that you need to transfer to Teams, see Manage phone numbers for your organization to select the correct country or region and download the correct forms and send them to us.
Using the Skype for Business admin center
Go to the Microsoft Teams admin center > Legacy portal.
In the left navigation go to Voice > Port orders > click Add.
On the New Local Number Port Order page, read the information and then click Let's get started.
On the Account info page, enter the following and then click Next:
Account number Account number for the service provider or carrier.
Billing telephone number must be in the E.164 format (requires a + sign to prepend the number). For example, for a North America number, use the format +1XXXYYYZZZZ.
PIN to unblock number PIN - if needed by your current service provider or carrier.
Company name This is the name of your company or organization.
The Company name box will only accept 25 characters that includes spaces. If the company's name is longer than 25 characters, the first 25 characters of the name will be submitted and the port order will still be processed.
Authorizing person Authorized user's name.
The Authorizing person box will only accept 15 characters that includes spaces. If the authorized person's name is longer than 15 characters, the first 15 characters of the name will be submitted and the port order will still be processed.
Service address Service address for the account. This will be listed on the bill from your service provider or carrier.
City, State, Zip of the service address.
On the Numbers page, enter the phone numbers that you want to transfer in E.164 format. For example, for a North America number, use the format +1XXXYYYZZZZ. Use a comma to separate multiple phone numbers.
If you are doing a full-port, you need to include the service Billing Telephone Number (BTN) in the list. If you are doing a partial-port, leave the service Billing Telephone Number (BTN) out of this list.
If you are doing a full-port, select I am transferring all my numbers from my current carrier. If you are doing a partial-port, select I'm only transferring some of my numbers. After you choose the right one, click Check number portability.
On the Transfer date page, on the Day drop-down list, select the date and under the Start time drop-down list, select the time (EST) and then click Next.
On the Letter of authorization page, check each of the following boxes. Then under the Signature box, type the person that is authorized to make changes to the account. This is the same name that is used on the Account Information page > Authorizing person. Then click Next.
On the Submit page under Other people to notify enter any other email address of the people you want to and click Submit port order. The port order will now be listed on the Port orders page. You can view the status of the order under Status column. You can view details of the port order such as the Order ID, Submitted, Transfer date and Status. You can see more details for the port order in the Action pane, including the name of the carrier.
What happens next?
Once your port order has been submitted and received, you will be sent an email that verifies your port order.
Your port order request will be checked and updated daily and you will be notified of its progress and status in email. If your request is rejected, you will be asked to open a support ticket and in that support ticket we ask that you provide Port Order ID. The port order ID can be found in the Skype for Business admin center under Voice > Port orders > Order ID column.
What if I have problems?
The service address isn't the same as the billing address. The address information I submitted on the order matches my customer's bill copy, why is it still rejecting? Most carriers will identify the porting information based on the service address information, not the billing address. Since a bill copy is a billing record, it may not provide the same information as the service address for the telephone number(s) being ported.
What should I do if my order is taking too long to process? We want number porting to be a very simple and quick process. If your order is taking longer than you think it should and the status still doesn't show as complete in the Skype for Business admin center, please open a support ticket and include the port order ID.
