Port your number to LineHQ
Switch without losing the number your customers already know. LineHQ ports most UK landline and business numbers over for free, then forwards them to any phone — so you keep your identity and drop the physical line rental.
// the short answer
Number porting moves an eligible existing UK landline, 0800 or 03 number to LineHQ. We check the number and provider details, arrange the required identity checks and agree the transfer with the losing provider. Keep the old service active until the port is confirmed and tested; a brief interruption at cutover is possible.

Keep your number
Bring your existing landline, 0800 or 03 number with you — customers, letterheads and listings stay unchanged.
Free to port
We handle the transfer with the losing provider at no cost; you just tell us the number and account details.
A planned switch-over
Keep the existing service running while the transfer is arranged. We agree the cutover with the providers, but cannot guarantee zero interruption. Test calls and routing after completion.
Drop the physical line rental
Once ported, there’s no physical line to pay for — the number lives in the cloud and rings the phones you already own.
Frequently asked questions
Can I move my landline number to VoIP?
Yes — most UK geographic landline numbers, plus 0800 and 03 numbers, can be ported to LineHQ. You keep the number and we forward it to whichever phone you choose.
How long does porting take?
Porting timescales depend on your current provider, but simple single-line ports usually complete within a couple of weeks. Your number keeps working until the switch-over.
Does it cost anything to port my number?
No — porting your number into LineHQ is free. You’ll need your account number and details from your current provider to start the request.
Will my number keep working while it’s being ported?
Keep your existing service active while the port is arranged. The providers agree a cutover, but a brief interruption is possible and timing depends on the losing provider. Do not cancel the old service until we confirm completion and you have tested incoming calls and routing.
What details do I need to port my number?
Give us the number, current provider and account details. Support checks eligibility and enables the porting workflow where needed. The account owner must complete any required Stripe Identity document and selfie checks before we submit to the carrier. We will tell you about any additional evidence or authorisation required.
Which numbers can I port to LineHQ?
Most UK geographic landline numbers, along with 0800 freephone and 03 national numbers, can be ported to LineHQ. Once moved, the number forwards to any phone you choose with full call handling — forwarding, recording and voicemail-to-email — and there’s no physical line rental to pay afterwards.
Can I port my number away from LineHQ later?
Yes, subject to eligibility and the usual provider checks. Start with the new provider and use the port-away request in LineHQ where available, or contact support. Keep the number and account active until completion; cancelling or releasing it first can interrupt the transfer. Subscription cancellation is separate from moving a number.
How do I start a number transfer?
Contact LineHQ first with the number and current provider. We check whether it can move, explain the documents and account checks, and guide you through the port-in request. Buying a new number and transferring an existing one are different processes; a port is not an instant activation.
