It is part of the Turkish national numbering plan, which adheres to ITU-T E.164 recommendations. The code covers the administrative province of Amasya, including its central district and the surrounding towns and villages.

Dialing Formats
When calling a fixed-line subscriber in Amasya from within Türkiye, you must dial the trunk prefix 0, followed by the area code 358 and the 7-digit local subscriber number. For example, a local number such as 212 34 56 would be dialed as 0 358 212 34 56 from any other province in Türkiye.
For international callers, the Turkish country code (+90) replaces the trunk prefix. Thus, the same number would be dialed as +90 358 212 34 56 from abroad. When dialing locally within Amasya, the area code may be omitted, and only the 7-digit subscriber number is required (e.g., 212 34 56). However, due to the possibility of number portability and the introduction of overlay codes in some regions, it is always safe to include the area code even for local calls.
Regulatory and Technical Notes
The Information and Communication Technologies Authority (BTK) of Türkiye manages the national numbering plan. Area code 358 is classified as a geographic code, meaning that the tariff for calls to this code is typically based on the distance and the caller's location. However, with the widespread adoption of VoIP and mobile telephony, many calls are now priced uniformly regardless of geographic distance.
Number portability is available in Türkiye, allowing subscribers to retain their geographic numbers even if they move to a different operator. However, the geographic significance of the code remains tied to the original location of the number's assignment. For businesses, having a 358 number signals a local presence in Amasya, which can be beneficial for customer trust and local SEO.
When dialing from a mobile phone in Türkiye, it is common practice to include the leading '0' before the area code, as mobile networks require the full national significant number. For international callers, it is essential to drop the leading '0' and use the +90 country code. Always verify the current dialing procedures with your telecom provider, as routing may vary.
