Area Code 620 – Tipperary/Cashel

Geographic Coverage and Administrative Jurisdiction

The Irish area code +353 620 is a geographic National Destination Code (NDC) assigned to the Cashel and South Tipperary region. This code covers the historic town of Cashel, renowned for the Rock of Cashel, and extends to surrounding communities in County Tipperary. The administrative jurisdiction falls under the South Tipperary area, which is part of the larger Tipperary county in the province of Munster. The code serves both residential and business lines within this defined geographic area, adhering to the Irish national numbering plan as regulated by ComReg (Commission for Communications Regulation).

Primary Cities and Towns Served

Beyond Cashel, the +353 620 code encompasses several key localities, including Rosegreen, Golden, and Dundrum. These towns and villages form a cohesive local exchange area, with the code facilitating direct dialing within the region. The area is characterized by a mix of rural communities and small urban centers, with Cashel being the principal hub for commerce and public services.

Dialing Formats and Caller Instructions

Local (National) Dialing

When placing a call from within Ireland to a number in the Cashel area, subscribers must use the national dialing format: 0620 XXXXX. The leading '0' is the national trunk prefix, followed by the area code '620' and the subscriber's 5-digit local number. For example, a local call to a business in Cashel would be dialed as 0620 12345.

International Dialing

For callers outside Ireland, the international format requires the country code +353, followed by the area code without the leading '0', and the subscriber number. Thus, the same Cashel number would be dialed as +353 620 12345. This format is essential for international callers to correctly route their calls through the global PSTN.

Overlay Considerations and Numbering Plan

Currently, there is no overlay code for the 620 area. The region retains its distinct geographic identity, and number portability allows subscribers to retain their numbers when switching providers within the same geographic area. However, it is important to note that the 620 code is not used for mobile services; mobile numbers in Ireland typically begin with 08x prefixes and are non-geographic.

Caller Instructions for Local and Foreign Callers

• Local callers within Ireland should always include the '0' trunk prefix when dialing a 620 number from a different area code. For calls within the same local area, the area code may be omitted in some cases, but it is recommended to use the full national format to avoid misdialing.
• International callers must replace the '0' with the +353 country code. Ensure you have the correct international exit code for your country (e.g., 00 from most European countries, 011 from North America) before dialing +353 620 XXXXX.

Understanding these dialing protocols ensures seamless connectivity to the Cashel and South Tipperary region, whether you are a resident, business, or international caller.
