Area Code 28 – Caledon/Hermanus/Southern coast of Western Cape/Swellendam

Overview of Area Code +27 28

Area code 28 is a geographic National Destination Code (NDC) within the South African national numbering plan, assigned to the southern coastal region of the Western Cape province. This area code serves a diverse mix of towns and rural communities, including Caledon, Hermanus, Swellendam, and the surrounding coastal and agricultural areas. It is part of the broader telecommunication infrastructure that connects this scenic region to the rest of South Africa and the world.

Geographic Coverage and Administrative Jurisdiction

The +27 28 area code covers a substantial portion of the Overberg and Cape Winelands districts, extending from the Hottentots Holland Mountains to the coast. Key towns and municipalities within this code include:

• Caledon – the administrative center of the Theewaterskloof Local Municipality, known for its hot springs and agricultural economy.
• Hermanus – a popular coastal town and whale-watching destination, part of the Overstrand Local Municipality.
• Swellendam – one of the oldest towns in South Africa, located in the Swellendam Local Municipality, near the Langeberg mountain range.
• Other communities – including Stanford, Gansbaai, Napier, Bredasdorp, and Greyton, all of which fall under the same NDC.

Administratively, the region falls under the Western Cape provincial government, with local municipalities overseeing service delivery. The area code is managed by the Independent Communications Authority of South Africa (ICASA) and allocated to fixed-line operators such as Telkom, as well as alternative licensed operators.

Dialing Formats and Caller Instructions

To call a landline number in the 28 area code, the national dialing format is 028 XXX XXXX (when dialed from within South Africa, the leading 0 is used). From outside South Africa, callers must use the international format: +27 28 XXX XXXX (dropping the leading 0). For example, a local number in Hermanus might be 028 312 3456; internationally, it would be dialed as +27 28 312 3456.

When calling from a mobile phone within South Africa, it is essential to include the area code even if the caller is in the same region, as mobile numbers are non-geographic and require full national numbering. For international callers, the plus sign (+) represents the international access code, which varies by country (e.g., 00 from many European countries, 011 from the US/Canada).

Overlay and Numbering Considerations

As of the latest ICASA numbering plan, there is no overlay code for the 28 area; it remains a standalone geographic code. However, number portability allows subscribers to retain their numbers when switching service providers, though the geographic significance remains tied to the original location. The area code is expected to remain stable, but users should verify the latest dialing procedures with their service provider, especially for VoIP or international calls.

For businesses and residents in this region, using the correct area code is crucial for successful call routing. The region's economy relies on tourism, agriculture, and fishing, making reliable telecommunications essential for local enterprises and international connectivity.
