Area Code 299 – Soc Trang province

Overview of Area Code 299 (Soc Trang Province, Vietnam)

Area code 299 is the National Destination Code (NDC) assigned to the landline telephone network of Soc Trang Province, a coastal administrative region in the Mekong Delta of southern Vietnam. Under the ITU-T E.164 international numbering plan, the full international dialing format for a fixed-line subscriber in Soc Trang is +84 299 XXX XXXX, where +84 is the country calling code for Vietnam, 299 is the geographic area code, and the remaining seven digits (XXX XXXX) constitute the local subscriber number. This structure is consistent with Vietnam's national numbering plan, which migrated to a unified 10-digit format for fixed-line services in 2017.

Geographic Coverage and Administrative Jurisdiction

The 299 code serves the entire province of Soc Trang, including its capital city, Soc Trang City, and all districts such as My Xuyen, Long Phu, Cu Lao Dung, Tran De, Thanh Tri, My Tu, Ke Sach, and Chau Thanh. The province is home to a significant Khmer population, and the area code covers both urban and rural exchanges. As a geographic code, 299 is tied to the physical location of the subscriber's line, and it is administered by the Vietnamese Ministry of Information and Communications (MIC).

Dialing Formats and Caller Instructions

For callers within Vietnam, dialing a Soc Trang fixed-line number requires the trunk prefix 0 followed by the area code and subscriber number: 0299 XXX XXXX. For example, to call a landline in Soc Trang City from Ho Chi Minh City, you would dial 0299 XXX XXXX. International callers must replace the trunk prefix with Vietnam's country code +84 and omit the leading zero, resulting in +84 299 XXX XXXX. For instance, a call from the United States would be dialed as 011 84 299 XXX XXXX (or +84 299 XXX XXXX on mobile phones).

Overlay and Numbering Considerations

Currently, there is no overlay code for Soc Trang; the 299 code is the sole geographic code for the province's fixed-line network. However, as with all Vietnamese fixed-line numbers, the subscriber number length is fixed at seven digits, and the total length of a national significant number (NSN) is nine digits (excluding the trunk prefix). It is important to note that mobile numbers in Vietnam use separate non-geographic prefixes (e.g., 09x, 08x) and are not affected by geographic area codes. When dialing from abroad, ensure you use the correct international exit code for your country, followed by Vietnam's country code and the full number without the leading zero.
