Area Code 226 – Yalova

Geographic Overview

The +90 226 area code is the National Destination Code (NDC) for the province of Yalova, located in the Marmara Region of northwestern Turkey. Yalova is a coastal province situated on the eastern shore of the Sea of Marmara, approximately 60 kilometers south of Istanbul. The province is known for its thermal springs and as a popular weekend retreat for residents of Istanbul, reachable by ferry. The area code 226 covers the entire province, including its administrative center, Yalova city, and all districts such as Altınova, Armutlu, Çınarcık, Çiftlikköy, and Termal.

Dialing Formats

When calling a fixed-line number in Yalova from abroad, the international format is +90 226 XXX XX XX, where +90 is the country code for Turkey, 226 is the area code, and the following seven digits represent the local subscriber number. For example, a typical Yalova landline might be dialed as +90 226 815 12 34.

Domestic callers within Turkey must dial the national trunk prefix 0 before the area code when calling from a different province: 0 226 XXX XX XX. However, when dialing from within the same area code, only the seven-digit subscriber number is required (e.g., 815 12 34).

Numbering and Overlays

Yalova's fixed-line numbers are part of Turkey's geographic numbering plan, which assigns area codes based on administrative provinces. The 226 code is used exclusively for fixed-line (PSTN) services, including traditional analog lines and VoIP services that are registered to a physical address within the province. There are no overlay codes in Yalova; the area code is unique to the province, and no additional NDCs have been introduced to serve the same geographic area.

Caller Instructions

• Local callers (within Yalova): Dial the 7-digit subscriber number directly, without the area code.
• National callers (from other Turkish provinces): Dial 0, then the area code 226, followed by the 7-digit subscriber number.
• International callers: Dial the international access prefix (e.g., 00 from most countries), then Turkey's country code 90, followed by the area code 226 (without the leading 0) and the subscriber number.

For example, a caller from Istanbul would dial 0 226 815 12 34, while a caller from Germany would dial 00 90 226 815 12 34.

Regulatory Notes

Numbering resources in Turkey are regulated by the Information and Communication Technologies Authority (BTK). Geographic area codes are allocated to fixed-line operators, and subscribers may keep their numbers when changing operators within the same geographic area (local number portability). However, number portability does not allow transferring a geographic number to a different province. As of recent years, Turkey has been transitioning to all-IP networks, but the geographic numbering structure remains unchanged.
