portout

Port-out is the process of transferring a telephone service from one telecommunications provider to another, while keeping the same telephone number whenever possible. It applies to mobile, fixed-line, and sometimes VoIP numbers, and is intended to reduce customer switching costs and foster competition. The process is typically governed by national regulation and carrier policies.

How it works:

- The customer initiates a port-out with the destination provider (and may need to provide account details or a porting authorization code).

- The current provider verifies identity, checks for any outstanding balances or contractual obligations, and approves or denies the request.

- A porting reference, authorization code, or equivalent is issued if required in the market.

- The new provider submits the port request to the current operator and schedules a porting date or window.

- On the port date, the number is migrated to the new network; service continuity is aimed for with minimal interruption.

- After the port completes, the old provider disconnects the service and the new provider activates the customer’s line.

Timeframes and costs: Mobile port-outs commonly complete within one to three business days, though some markets offer same-day or next-day porting. Most operators do not charge for a standard port-out, but fees may apply for contract termination, device subsidies, or exceptional circumstances.

Security and regulatory context: Port-outs can be vulnerable to fraud, such as unauthorized requests or SIM swap scams; carriers use verification steps to mitigate risk. Number portability is widely supported by regulators to promote competition and consumer choice.
