Can I transfer my landline number to VoIP?

Yes, you can keep your landline number with VoIP. We can transfer UK landline numbers beginning with 01 and 02 plus 03 numbers for you to use with our VoIP service. It takes just a few simple steps to transfer existing landline numbers to VoIP. This means that you don't have to get rid of any of the phone numbers that your contacts and customers are already familiar with.


Once transferred in, your landline number will be able to receive inbound and make outbound calls in combination with your VoIP service.


You can check how much it will cost to transfer a phone number to VoIP and if you'd like us to check your number before you make a request, just drop us a line at


In order to transfer the number to your account, you will need to provide proof of address, identity and ownership documentation to ensure that you are the number owner. Additionally, to make the online number transfer process as quick and as smooth as possible, you will need to answer the following questions via our online portal. Once ported over, you will be able to use your number as a virtual VoIP number and enjoy crystal clear calling.


Number Details

1. Do you have broadband on this line?

When you transfer a number, any features currently attached to it are lost on the day the port completes. This includes broadband so it’s really important you make alternative arrangements if you will still need a broadband service.


Some ISP’s will be able to move your broadband to a new number & leave the transfer number active until it ports away. Do give your current provider a call & see what they are able to offer you before you apply for your transfer.


2. Do you have an alarm or security monitoring on this line?

Your alarm company will not allow your number to be transferred if it’s a security line & will instantly reject our order. As we’re charged for each submission regardless of its outcome, you’ll need to have the security feature removed before applying for the transfer.


3. Is this a single or multi line?

These are the 2 different types of lines in the UK. Your bill may show the type of line & some providers list a multi line as an ISDN2e. If you’re unsure, your current provider will be able to tell you.


A transfer order must specify this line type & faces instant rejection by your provider if it’s incorrect. We are then required to place a fresh order & whilst we can offer this at a reduced price, we would prefer to avoid this for you where possible!


All lines take approximately 2-3 weeks to complete transfer. Single lines tend to be at the lower end of this, whilst multi lines tend to be nearer the higher end.


4. Do you have DDI’s associated with this number?

If your number has additional DDI (Direct Dial Inward) numbers or other associated numbers attached to it, these will usually need to be ported at the same time. The cost for each additional number is charged at the usual standard number cost. You’ll need to drop us an email with the additional numbers listed if they aren’t shown on your invoice!


5. Do you know if your billing provider differs from your communications provider?

These are often 2 different companies & especially if your billing provider is a reseller of numbers. If you have ported your number before, just let us know who you ported it to.


6. What is the ‘Registered Postcode’ of the number you are porting?

UK porting is regulated by postcode for security so we have to send off your transfer order with the correct postcode to pass this. If we apply with the wrong postcode, your order will be rejected by your provider & a fresh order must be sent off. Whilst we can offer this at a reduced price, we would prefer to avoid this for you where possible!


The postcode may not be the same as your invoice as some invoices show a billing address rather than a registered address. It may also not have been reflected on your invoice following a recent move or account update. Some very old phone numbers are even still registered to the local exchange!


If you’re in any doubt at all, your current provider will be able to tell you. Just be sure to ask for the registered postcode for porting purposes (as opposed to billing or location).


Update your number details



Proof of Ownership

This must show the phone number you want to transfer along with your name & the registered postcode. It would usually be found on your latest invoice. If your invoice is missing any of the information, you can take screenshots from your online portal & send those across to the porting team.


Proof of Identity

This is your passport, driving licence or nationally recognised photographic ID. Business accounts can provide the documents for the Account Holder or those of the current Director/Partner of the business.


Proof of Address

This should be a bank statement or utility bill dated in the last 3 months. It should match the address on the account or the address on the Proof of Ownership document.
