Overview of +90 542

The +90 542 prefix is a non-geographic mobile network code assigned within the Turkish numbering plan, managed by the Information and Communication Technologies Authority (BTK) under the ITU-T E.164 international standard. This prefix is allocated to mobile network operators (MNOs) and mobile virtual network operators (MVNOs) serving subscribers across all 81 provinces of Türkiye. Unlike geographic area codes, 542 does not correspond to a specific city or region; instead, it identifies the mobile network and enables nationwide roaming and connectivity.

Technical Specifications and Formatting

Numbers bearing the 542 prefix follow the standard Turkish mobile numbering structure: +90 542 XXX XX XX (12 digits in international format) or 0542 XXX XX XX (11 digits in national format). The leading '0' is used for domestic calls and is dropped when dialing from abroad. The prefix is part of the National Destination Code (NDC) and is followed by a seven-digit subscriber number. These numbers support full PSTN and VoIP integration, including SMS, MMS, and high-speed data services.

Calling Instructions

  • Domestic calls (within Türkiye): Dial 0542 XXX XX XX from any fixed or mobile line.
  • International calls (from abroad): Dial your country's exit code (e.g., 00, 011), then 90 542 XXX XX XX (omit the leading '0').
  • Receiving calls while roaming: The number remains reachable via the same international format; no additional codes are required.

Regulatory and Porting Considerations

Subscribers may retain their 542 number when switching operators due to mobile number portability (MNP). This means the prefix does not guarantee a specific operator; the actual carrier can be identified via a number lookup service. The prefix is non-geographic, so calls to 542 numbers are not subject to distance-based tariffs. However, international call rates apply when dialing from outside Türkiye, and roaming charges may apply when the subscriber is abroad.

Usage and Availability

The 542 prefix is widely used for personal and business mobile lines, including IoT and machine-to-machine (M2M) communications. It is not reserved for any special service or emergency use. For callers, it is essential to use the correct international format to avoid misdialing. For example, a full international call would be +90 542 123 45 67. Always verify the number's current operator and validity through official databases if needed.
