Retaining your existing phone number when switching to a VoIP system is a common concern for many businesses. Number porting allows you to transfer your landline or business phone number to a new provider, ensuring continuity without disruption to your operations or customer communication.
Switching to a VoIP phone system offers numerous benefits, from cost savings to greater flexibility, but many businesses worry about losing their established phone number in the process. Fortunately, number porting enables businesses to transfer their existing numbers to a VoIP service with minimal hassle. This ensures a smooth transition without the need to update customers, suppliers, or marketing materials with a new number.
What is Number Porting?
Number porting is the process of transferring an existing phone number from one service provider to another, for example to a VoIP phone system provider. This allows businesses to continue using their current number. The process is regulated by OFCOM, ensuring you can move your phone number without barriers and with minimal disruption.

Why Keeping Your Phone Number Matters
Keeping the same phone number is important to maintain business communications. Customers, suppliers, and partners expect to reach a business at the number they have always used. Changing numbers can create confusion, leading to lost opportunities and reduced trust. Additionally, updating marketing materials, websites, and business cards with a new number can be time-consuming and costly. Number porting eliminates these issues by ensuring uninterrupted communications.
How the Number Porting Process Works
To port a number, businesses will need to provide the new provider with specific details, including their current provider’s name, the number(s) to be ported, and the associated billing address. The new provider will handle the transfer process, often requiring a Letter of Authority (LOA) from the business to request the port. The process is usually seamless, with minimal downtime, and businesses are typically informed of the expected completion time.
Considerations When Porting a Number
While number porting is generally straightforward, businesses should check for any contractual obligations or early termination fees with their current provider. Some numbers, particularly those tied to specific regional or legacy services, may not always be eligible for porting. Verifying eligibility with both the current and new provider can prevent unexpected complications.
