Number transfers
Move your business numbers to TISA and keep the number your customers already ring.
A business mobile number moves on a PAC code you request from your current provider by texting PAC to 65075; a landline number has no PAC and is transferred for you on a written request TISA raises with the losing provider.
Mobile numbers transfer within one business day of the request; landline and VoIP numbers typically take 7 to 10 working days. You pick the date, and your current service runs until the switch.
TISA Business support is open Monday to Friday, 9.30am to 5pm. Outside those hours, email [email protected].
Two routes
Mobiles move with a code. Landlines move without one.
If you have both, run the two together and give us one date for the lot.
Mobile numbers
You request a PAC, we do the rest
Free, arrives by text, valid for 30 days.
- 01
Text PAC to 65075
From the business line you are moving. The code comes back by text. One code per line, so send it from each phone in turn.
- 02
Send us the code
With the number it belongs to and the date you want it to move.
- 03
We book the transfer
Mobile numbers move within one business day of the request, in line with Ofcom rules. Your current service runs until the switch.
- 04
The number lands on TISA
On the date you chose, it stops on the old network and starts on your TISA SIM.
Landline numbers
There is no PAC for a landline
Landline and 03 numbers move on a written request, which TISA raises for you.
- 01
Send us the numbers
Exactly as your current provider holds them.
- 02
Send us a recent bill
It proves whose account the numbers sit on. A mismatch gets the transfer rejected.
- 03
We raise the transfer
We confirm the date with you before anything moves.
- 04
The number rings on Cloud PBX
It lands on TISA Cloud PBX and rings a desk phone, a laptop and a mobile together.
Before you start
Six things that decide whether it runs or bounces.
- What it costs
- Nothing for a mobile. Moving a business mobile number to TISA is free. A UK landline, 03 or freephone number, or an inbound number in another country, is charged once per porting request: the figures are in the price guide.
- Who can ask
- The account holder, or someone authorised on the account. Nobody else.
- Getting it right
- Numbers, account name and address must match your current provider character for character. This is the most common reason a transfer bounces.
- How long
- Mobile: one business day from the request, in line with Ofcom rules. Landline and VoIP: 7 to 10 working days. You name the date.
- Several lines
- One PAC per line. Send them together and they move on the same date.
- Your old contract
- Ofcom prohibits charging for the PAC or STAC itself. It does not remove an early termination charge if you are inside a minimum term. Check your terms first.
Requesting a PAC cancels nothing on its own. An unused code simply expires after 30 days.
