Area Code 47 – Hambantota

Overview of Sri Lanka Area Code +94 47

Area code 47 is a geographic National Destination Code (NDC) assigned to the Hambantota District, located in the Southern Province of Sri Lanka. This code is part of the national numbering plan administered by the Telecommunications Regulatory Commission of Sri Lanka (TRCSL) under the ITU-T E.164 international standard. When dialing internationally, the full number format is +94 47 X XXXX, where +94 is the country calling code for Sri Lanka, 47 is the NDC, and the remaining subscriber number typically consists of 7 digits, resulting in a total of 10 digits after the country code.

Geographic Coverage and Administrative Jurisdiction

The 47 area code serves the Hambantota District, an administrative district in the Southern Province. Key towns and localities covered include Hambantota (the district capital), Tangalle, Ambalantota, Tissamaharama, and Beliatta. The district is known for its strategic port, wildlife parks (e.g., Yala National Park), and developing industrial zones. The area code is used for fixed-line (PSTN) services, including both traditional copper lines and fixed wireless (CDMA) connections, as well as some VoIP-based fixed services that require a physical address within the district.

Dialing Formats and Instructions

For callers within Sri Lanka, the national trunk prefix is 0. Therefore, to call a fixed line in Hambantota from another part of the country, you would dial: 047 X XXXX. For example, if the subscriber number is 222 3456, you would dial 047 222 3456 domestically.

For international callers, you must omit the leading zero and use the country code. Thus, the same number would be dialed as +94 47 222 3456 from any country. When saving the number in a mobile phone, it is best practice to store it in international format: +94 47 222 3456. This ensures proper routing regardless of the caller's location.

Overlays and Numbering Considerations

Currently, there are no overlay codes for the Hambantota area; the 47 code is unique to this district. However, due to the growth of telecommunications, number portability is available in Sri Lanka for fixed-line services within the same geographic area. This means that a subscriber may retain their 47 number even if they switch service providers, as long as they remain within the same geographic region. It is important to note that the 47 code is not used for mobile services; mobile numbers in Sri Lanka begin with 7X (e.g., 70, 71, 72, 75, 76, 77, 78) and are non-geographic.

Practical Tips for Callers

When calling Hambantota from overseas, be mindful of time zones (Sri Lanka Standard Time, UTC+5:30). Also, ensure you have the correct international exit code for your country (e.g., 011 from the US, 00 from most European countries) before dialing +94 47... If you are traveling in Sri Lanka and need to call a local Hambantota number, you can use the domestic format 047... from any phone, including mobiles, without incurring international charges.
