port landline number to BT

Hi all,

I have a telephone number with another service provider that I'd like to port to my existing BT landline. I seem to remember there being an option to port a number when signing up for a new BT line but I'm far beyond that point now and have a BT line in place.

Does anyone know if there's a BT online form anywhere that can be filled in to start the number porting process now? Or is it a case of calling BT support to get the ball rolling? Thanks

Re: port landline number to BT

Is the number you want to port originally a BT number?  Or was it allocated from the current provider

The number was originally a Virgin Media number that was successfully ported to sipgate, a VoIP service that unfortunately didn't work well for us so I'm hoping that I can now port that number once again from sipgate to BT.

Re: port landline number to BT

As this is not a BT NUMBER but originally virgin I don't think you will be able to port the number as moving from existing provider the number will return to virgin

Thanks, I have to say that your theory sounds a bit bonkers but you could be right.

I think I'll have to give BT CS a call to see if they have any idea if porting has a chance of working.

Re: port landline number to BT

If you use search for porting landline number you will see the problem which I have posted

you also need to realise that virgin system is totally different to the openreach/BT system

Re: port landline number to BT

@fibre-hobo 

Each individual BT exchange has its own unique number range which cannot be changed as its determined by the physical hardware. This is because the exchanges are very old now (circa 1980s). and number portability was not even considered then.

Virgin have a totally different network and numbering system.

Porting BT numbers out to other providers is not a problem, but the number will always belong to BT, and will return to them if any further porting is attempted.

Re: port landline number to BT

Is your current ‘existing BT landline ‘ a working line with a BT number ?, if so , and it’s possible to do what you want ( renumber an existing BT number , to a number that is working with another provider that is already ported from a third company,)  I can only see problems, the first being getting someone to say ‘it’s possible’ rather than just saying ‘No’.
In effect your ‘order’ would need to stop your existing number ( without ceasing the broadband associated with it ) and renumber it to a number with a VOIP provider...I’m not sure that type of order even exists , if it does, then it would require the VOIP provider not to return the number to Virgin when your VOIP service is ceased ( obviously if you served ‘notice’ to the VOIP provider that you were leaving that’s what would happen , the gaining provider would have to serve your notice ) then it gets opaque, do Virgin port direct to BT, or do Virgin continue to port to VOIP and they ‘re-port’ to BT , porting a ported number has never been ( to me at least ) explained.
There has been some chat on this or similar forums from consumers who want to move a phone number to a VOIP provider without ceasing their broadband service that the phone number hosted, it was stated that a ‘stop, port and start renumber‘ order was available from BT Wholesale to supposedly arrange that, but the person asking the question ( AFAIK) never commented on if they ever got what they wanted without losing broadband for a while....your case is IMHO even more complicated.
Number port as never designed to be ‘it’s my number and I can move it where I like’ , the fact is it was initially designed when there were only really two options , BT and the regional cable company, the arrangement was reciprocal, if you wanted to import numbers ( this was massively to the cable company’s benefit ) you had to export too, but initially at least , the vast majority were from BT to cable, adding in technological advances like VOIP providers as well as the more traditional networks , and the many many providers that now exist it’s not surprising that the initial concept struggles to keep up with customer expectations, you may be expecting too much from the system, and even if the system has this set of circumstances covered, getting an agent to recognise it, and 3 company’s to coordinate, when one has no relationship with you, and another is about to have no relationship with you.

Re: port landline number to BT

Yes the BT line that we have now is a recently installed line on the fttp (full fibre) service with a working number on BT digital voice . The BT porting and routing team chap that I spoke to this morning spoke to the fttp team and unfortunately he confirmed what the two other posters in this thread said, at this time the only type of number that can be ported in to BT is a BT number, they're working on enabling this type of port in the future but at the moment there is no timescale.

Virgin Media did manage to port the number to sipgate whilst maintaining broadband service on the Virgin account (an account now closed) but it is now clear that this number I'd like to get ported to BT is still "owned" by Virgin Media.

I think we can call this case closed and that this particular number port is not going to happen. Perhaps one day all landline numbers will be portable to any service provider similar to what is possible with mobile numbers with a PAC code. For the moment we're nowhere near that dream.

Thank you to everyone for the help and input.

Re: port landline number to BT

Until all networks are IP based, which is going to be a long time in the future, porting numbers are gong to present problems due to the different signalling systems that are in use.

Even when that does happen, each provider will still have their own number ranges as defined by Ofcom. This will mean that eventually numbers will always revert back to the number range holder.

If you are interested, you can look at the Ofcom website.

If you have a quick look at the OFCOM website :-

http://static.ofcom.org.uk/static/numbering/index.htm#geog1

and download the spreadsheet that contains the number range you are interested in (note the numbers exclude the leading zero). The line in the spreadsheet will show to whom the range is allocated.
