Mobiilinumeroita, also known as mobile numbers, are unique identifiers assigned to mobile phone subscriptions. These numbers are crucial for establishing communication between mobile devices and the wider telecommunications network. In most countries, mobile numbers follow a specific format, typically including an international dialing code, a country code, and a national subscriber number. The structure and allocation of mobile numbers are managed by national regulatory authorities.

Mobile numbers are essential for making and receiving calls, sending and receiving text messages (SMS), and accessing various mobile services. They are often used for authentication purposes, such as two-factor authentication for online accounts. The portability of mobile numbers allows users to switch mobile network operators while retaining their existing number. This portability is a regulated right in many regions, ensuring consumer choice and competition within the mobile market.

The concept of mobile numbers has evolved significantly with the growth of mobile technology. Initially, numbers were simpler and tied to specific physical locations or devices. Today, they are largely virtual identifiers linked to a SIM card or eSIM, enabling flexibility and mobility. The increasing demand for mobile services has led to the efficient management and allocation of number blocks to operators by regulatory bodies to avoid exhaustion.
