Number porting means moving an existing phone number from one operator to another while keeping the number. You change provider without changing your number. It applies to both fixed numbers and mobile numbers and is a regulated right, not something an operator can refuse without cause.
How a number port works
The port is handled between the operators, but you start it with the new provider.
- You order the port with the new operator and supply the number.
- The new operator requests the number from the old one.
- A date is set when the number moves across.
- At the switch the old subscription ends and the new one takes over.
A mobile number often moves within one business day. Fixed numbers and larger ranges can take a little longer.
What to watch out for
- Do not cancel your old subscription yourself before the port is complete, or the number can be lost.
- Check that the subscription has no contract period that clashes with the move.
- Collect every number you want to move in the same order for a smooth transition.
For companies moving an entire phone system, porting happens as part of the switch to a new business switchboard, so all numbers come along.
Why it matters for businesses
Your number is part of your identity. Customers call it, it sits on print material and in contracts. With number porting you can move to a modern solution, such as IP telephony for business, without losing contact with the market.
