Portouts

Port-out is the process by which a customer transfers a telephone number from their current service provider to a new provider while keeping the same number. It is a component of number portability regimes that exist in many countries to promote competition and reduce switching costs for consumers. The goal is to allow users to change networks without losing a valued contact identifier.

Eligibility and prerequisites for porting vary by jurisdiction but share common requirements. The requester must typically be the account holder or an authorized user, and the number must be active and not blocked for porting due to fraud or unpaid balances. Finalization often depends on clearing any outstanding charges or contractual obligations with the current provider. Most regions require some form of proof of identity and the new carrier usually issues a porting authorization code or equivalent to initiate the transfer.

The port-out process generally follows these steps. The user contacts the destination carrier and provides the number to port, along with required account information and any porting authorization code. The destination carrier submits a port request to the current provider, which validates the request and releases the number if all conditions are satisfied. The transfer is completed within a regulated time frame, which can range from a few hours to several days, and may involve a short service interruption or a transition window. A new SIM or eSIM is typically issued for the destination network.

Potential issues include delays, verification holds, or incompatibilities in number formats. Porting is usually free or inexpensive, but some markets or providers may impose fees or require contract reconciliation. Regulations governing port-out and the timelines for completion vary by country and operator. See number portability for broader context.
