How porting works

With porting in general, Xfinity Mobile and their underlying carrier (Verizon) will initiate a port request for your phone number and send it to the current/losing carrier (NumberBarn). Learn about each step in the port out process here:

It’s important to remember that Xfinity Mobile must submit the port request with the exact porting credentials that are listed in your NumberBarn account. Once approved, it’s the responsibility of Xfinity Mobile and their underlying carrier to complete the porting request. 

Gathering your port out information

The following article guides you to your porting information including your Account Number, PIN, End User Name, Billing Telephone Number (BTN), and Service Address:

Be sure to provide this information to Xfinity Mobile and instruct them to use it to submit the port order. If we receive a port order that contains different information or no information, it may be rejected.

4 Tips for porting to Xfinity Mobile

1. Make sure Xfinity Mobile can support your number 

If you plan to port your number to Xfinity Mobile, it’s always a great idea to make sure they can support your number. Unlike some other providers, they don’t have a readily available means of checking whether your number is supported so it might be worth asking their support team. Here's the process to initiate the porting process on your Xfinity device.

It’s also a great idea to check before you purchase the number from NumberBarn to ensure that it’s compatible with your desired provider.

2. Make sure Xfinity Mobile knows this is a landline/wireline port so they can choose port settings appropriately

All numbers purchased from NumberBarn are classified as landline or wireline as opposed to wireless. To learn more about this important distinction, check out this article:

3. Make sure Xfinity Mobile is filling in all available fields on their port form

When submitting a port out request to Xfinity Mobile, it’s important that the request is submitted with all of the essential porting information. In addition to the porting information we mentioned earlier in this article, it’s especially critical that Xfinity Mobile include the following information in the porting request:

• Authorization Name
• Authorization Date
• Wireline (or landline)-to-wireless port
• Requested Due Date must be 2 business days in advance

Important! These fields may not be visible on Xfinity Mobile’s standard form, so you may have to ask them to escalate the port to someone who has access to manually enter these specific fields. If these fields are left blank, Xfinity Mobile will receive an automated error from their carrier (Verizon) that will not allow them to submit the port. Note that even though Xfinity resells Verizon Wireless service, Verizon will not assist with this porting process.

Furthermore, the Requested Due Date (RDD) for the port must be at least 2 business days in the future NOT counting today. So if today is Friday, the date needs to at least be for the following Tuesday.

If you encounter a "Porting error 1P: Verizon Number Lock" error when attempting to port your number it typically means that Xfinity left the "Authorization Name" field blank when they submitted their port through the Verizon porting system.

4. Once NumberBarn approves the port, contact Xfinity Mobile to confirm the date they will port the number

If you do not receive confirmation from NumberBarn that the port out has been completed on the date provided by Xfinity Mobile, reach out asking them to “activate” your number to complete the port request. 

Once the number ports to Xfinity Mobile and leaves our network, we will email you to confirm and remove the number from your NumberBarn account. At that point, you will no longer be billed for service through NumberBarn.

When you contact support, we recommend asking to speak with Tier 2 support. That's the highest tier a customer can speak with and they've proven to be quite helpful. You may also try reaching out to xfinitymobile_portinescalations@comcast.com as we've had some luck in getting porting support from this group.
