Maintaining seamless communication with customers and partners is crucial. Small businesses, in particular, need to stay flexible and responsive to their customers' needs. 

Often, businesses need to switch telephony providers to take advantage of better rates, improved service quality, or advanced features not offered by their existing providers. Additionally, companies may need to upgrade their phone systems or move to a different region while keeping their established contact numbers. 

Our guide will help you understand number porting and the benefits that number portability brings to your business.

What is Number Porting?

Number porting allows you to transfer your existing phone number from one provider to another. This process is essential for businesses looking to maintain a well established contact number when switching carriers or upgrading their phone systems.

“Phone providers must allow you to take their telephone number with you to a new provider when you switch. This is known as ‘number porting’.”

Ofcom

What are the Benefits of Number Porting?


Consistency
Keep your existing phone numbers to avoid confusion and maintain brand consistency.

Cost-efficiency
Avoid the costs and inconvenience of updating marketing materials and informing customers of a new number.

Flexibility
Switch providers for better service or rates without losing your established contact number.

How Does Number Porting Work?

  • Initiate the Request: Contact your new provider to begin the porting process. They will handle the coordination with your current provider.

  • Provide Necessary Information: Be ready to provide details like your current account number and a recent bill for verification.

  • Transition Period: The porting process usually takes a few days. Ensure you have a temporary solution to manage calls during this period.

Regulations and Compliance

Understanding the regulations and compliance requirements related to number porting is also important. In the UK, Ofcom regulates the allocation and porting of phone numbers - in order that these processes are fair and efficient. Ofcom also sets the rules for number porting and monitors compliance among service providers.

“Number portability is a regulated facility which allows customers to keep their numbers when changing provider.”
Ofcom

In addition, there are two other notable industry bodies that are involved in this sector. 

NICC – is a technical forum for the UK communications sector that develops interoperability standards for public communications networks and services in the UK.

OTA2 – the Office of the Telecommunications Adjudicator is an independent organisation tasked by Ofcom to oversee co-operation between communications providers and enable a competitive environment in the telecommunications sector.

What is the difference between Number Porting and Call Forwarding?


Number porting allows you to transfer your existing phone number from one service provider to another, ensuring continuity and avoiding the hassle of updating contact details. Number porting is ideal for businesses and individuals switching providers but wanting to retain their current phone number.

In contrast, call forwarding redirects incoming calls from one number to another based on specific conditions, such as when the line is busy or unreachable. This feature is set up through your phone or service provider and can be managed to ensure calls are never missed.

PAC Codes

A PAC (Porting Authorisation Code) is an essential part of the number porting process, allowing you to seamlessly transfer your mobile number from one network provider to another.

What is a PAC Code?

A PAC Code, or Porting Authorisation Code, is a unique nine-character identifier that allows you to transfer your mobile phone number from one network provider to another. This process ensures you can keep your phone number when switching networks, avoiding the inconvenience of updating your regular contacts with a new contact number. 
 

How does a PAC Code work?

Once a PAC Code is shared with the new provider, they contact your current provider to validate the code and confirm the number transfer. This step ensures your account details are securely matched to prevent unauthorised porting. Following verification, the new provider schedules the transfer, which is usually completed within one working day. The old provider will deactivate your service after the porting process concludes, and your number will be fully functional on the new network.

How to get a PAC Code

To get a PAC Code, request it from your current mobile network provider. 

According to uSwitch, "A PAC code should be given to you immediately over the phone or within two hours by text. This time frame is stipulated by the telecommunications regulator Ofcom." 

You have every right to complain if you don't receive your PAC code.

Here's how to get a PAC Code:

  • Via SMS: The simplest method is to text PAC to 65075 from the number you wish to transfer. This service is free and available for all UK mobile networks. Within seconds, you'll receive a text containing your PAC Code, along with details about any early termination fees or outstanding payments on your current contract.

  • Via Customer Service: You can also request a PAC Code by contacting your provider's customer service via phone or live chat. This might be necessary if you need additional clarification on your account details before switching.

  • Through an Online Account: Some networks allow you to request a PAC Code through their online portal or mobile app. This option provides convenience for users who prefer digital interactions.
