What this means if you’re on the Hartburn exchange

Openreach places an exchange on the FTTP priority list once full fibre reaches roughly 75% of the premises it serves. From the restriction date, any premises here that can order full fibre can no longer take out new copper services — analogue phone lines, FTTC broadband, working-line takeovers. Nothing is switched off on that date: existing lines keep working until your provider migrates you ahead of the national PSTN retirement on 31 January 2027.

When migration happens your number stays the same — local landlines here use the 01670 dialling code for Morpeth, which is unaffected by the switch-off. If a call from an unfamiliar local number is what brought you here, run it through the lookup to see the Ofcom range holder and live reputation reports.

FAQs about the Hartburn exchange

Is the Hartburn telephone exchange closing?

Hartburn was previously notified for copper stop-sell but has been removed from Openreach's FTTP priority list. The national PSTN switch-off on 31 January 2027 still applies: analogue landline service ends everywhere, and providers will migrate customers to digital voice.

What does stop sell at Hartburn mean for my landline?

Existing services keep working — stop sell only blocks new supply of copper products (new analogue lines, copper broadband, transfers between providers on copper) at premises where full fibre is available. When your provider migrates you, your phone number stays the same and calls move to digital voice over broadband.

Which numbers come from the Hartburn exchange?

Hartburn serves the Morpeth area, where landlines use the 01670 dialling code. Bear in mind UK numbers are portable, so a 01670 number no longer proves a physical line on this exchange — use the lookup to check any specific number.
