Area Code 74 – Phatthalung/Satun/Songkhla

Geographic Coverage and Administrative Jurisdiction

The area code +66 74 is a geographic National Destination Code (NDC) assigned to the southern region of Thailand, specifically covering the provinces of Phatthalung, Satun, and Songkhla. This allocation follows the ITU-T E.164 international numbering plan, where the country calling code +66 is followed by the NDC 74 and the subscriber number. The region is administered under Thailand's National Broadcasting and Telecommunications Commission (NBTC), which oversees the assignment and management of geographic numbers. Songkhla, with its major city Hat Yai, serves as the economic and transportation hub of the area, while Phatthalung and Satun are known for their natural attractions and border trade with Malaysia.

Dialing Formats and Caller Instructions

For local callers within Thailand, the trunk prefix 0 is used before the area code and subscriber number. Therefore, a local call to a fixed line in Hat Yai would be dialed as 0 74 123456. When calling from abroad, the international prefix (typically + or 00) is used, followed by the country code 66, the area code 74 (without the leading 0), and the subscriber number: +66 74 123456. It is important to note that the subscriber number length in this area is typically 6 to 7 digits, making the total national significant number (NSN) length 9 digits (including the leading 0).

Geographic Significance and Overlays

This area code is strictly geographic, meaning that the number is tied to a physical location and the associated telephone exchange. There are no overlay codes in this region; the 74 code is exclusively used for the three provinces. However, due to the increasing demand for telecommunication services, the NBTC has implemented number portability, allowing subscribers to retain their numbers when changing operators within the same geographic area. For businesses and residents, having a local presence with a 74 number can enhance trust and accessibility for customers in the southern provinces.

Practical Usage and Examples

To illustrate, a business in Songkhla might list its contact number as +66 74 555123 for international clients, while local customers would dial 074 555123. Similarly, a resident in Phatthalung would use the same area code, e.g., +66 74 612345. When traveling in the region, visitors should be aware that calls to these numbers are charged as local calls if dialed from within the same area code, but may incur long-distance charges if dialed from other parts of Thailand. Always verify the current dialing procedures with your service provider, as international dialing formats may vary by country.
