1. Paperwork
You’ll sign a letter of authority (CLOA) so we can request the port from your current provider. This applies to all line types, including single lines.
Switching to us
Most businesses keep their existing numbers. Here’s what porting usually looks like — in plain English, with typical timescales (not guarantees).
How number porting works
2. The port window
Ports are arranged on a working day. A morning slot is usually best; Fridays are best avoided. We don’t offer out-of-hours ports.
3. Go-live
Your numbers move across. Old lines typically cease automatically.

Exact timing depends on the losing provider and the numbers involved. Zero downtime is expected on the day, with a short response window if anything needs fixing — we’ll brief you before port day.
