Number porting
Number porting lets a subscriber switch phone carriers while keeping the same number; in Turkey the process is governed by a BTK regulation.
Number porting means moving a phone number to a new carrier (operator) while keeping the number itself. In Turkey the process is governed by the Number Portability Regulation issued by the Information and Communication Technologies Authority (BTK). Under Article 6, geographic (landline) numbers, non-geographic numbers (such as 0850) and mobile numbers are all portable. Porting from one carrier to another takes place between fixed networks or between mobile networks.
How it works
Under Article 7, porting starts when the subscriber applies to the new (recipient) carrier, and it cannot be started without the subscriber's request. The recipient carrier passes the request to the current (donor) carrier, and once the process completes the number moves to the new network. The recipient carrier tells you which documents and timeline apply. The regulation has been amended since it was first published, so check the current text and ask your carrier about deadlines and conditions. For numbers starting with 444, ask the carrier that issued the number what applies.
Why it matters
Your number is on business cards, on maps and in customers' contacts. Porting lets a business move to a new provider without losing it. If you would rather not port, the alternative is to keep the number with your current carrier and connect the line to the new platform over a SIP trunk (BYOC). To avoid dropped calls, schedule the switch for a quiet period and keep a fallback plan ready.
