# How to Port UK Numbers Into Invoca

> Porting UK numbers into Invoca requires a signed Customer Letter of Authority and a porting spreadsheet, and typically takes two to four weeks.

Porting phone numbers into Invoca from the UK involves a few steps. This guide covers the required documents and key timelines.

## Step 1: Prepare the required documents

**Customer Letter of Authority (CLoA):** confirms your current provider has your consent to release your numbers to Invoca. Reach out to your account team or [support@invoca.com](mailto:support@invoca.com) for the UK CLoA form. It needs to include:

* **Details of current and new providers:** names, addresses, and a contact email for both.
* **Numbers to be ported:** both Geographic (Geo) and Non-Geographic (Non-Geo) numbers. For Geo numbers, include the Main Billing Number (MBN) if known. Use continuation sheets for additional numbers and sites.
* **Your company's details:** company name as shown on your most recent bill, billing address (town/city, county, postcode), and your company registration and billing account numbers.
* **Authorization statement:** confirming you authorize Invoca to act on your behalf, and that your current provider can disclose the necessary details to complete the port.
* **Requester's information:** signed consent from an authorized representative, with name, job title, email, and date. A CLoA is valid for 30 days from the date it's signed.

**Porting template spreadsheet:** list every phone number to be ported, including:

* **Required:** Number to Port, Campaign URL
* **Optional:** Description, Media Type, Detected Destination, and any other marketing data to apply

## Step 2: Submit a support ticket

1. Reach out to your account team or [support@invoca.com](mailto:support@invoca.com) to create a new ticket with the subject and description "Request to port-in phone numbers," Case Reason "Number Management," and Sub-Category "Porting Numbers."
2. Attach your completed CLoA, your porting spreadsheet, and your phone bill if applicable.
3. Submit the ticket once everything is attached.

## Step 3: Await confirmation and updates

Once submitted, Invoca validates your information and coordinates with your current carrier, with regular updates along the way.

**Estimated timeline:** typically two to four weeks, depending on the carrier. You'll be notified when the port is scheduled and completed.

**Important notes:**

* Make sure all information matches your billing records exactly to avoid delays.
* The CLoA is valid for 30 days from its signing date.

**Common reasons for rejection:**

* Billing address mismatch
* Customer/business name mismatch
* Authorized name and signature mismatch
* Account with the losing carrier on hold due to non-payment
* Numbers on a bundle account that the carrier won't allow to port out individually
* A PIN is required for number release

A corrected request is resubmitted as a new order, which increases the total time to port.
