📍 Geographic Location of Donegal
Geographic Overview
The +353 7497 prefix is a geographic National Destination Code (NDC) assigned to the Donegal numbering area of the Republic of Ireland. This area code covers a portion of County Donegal, specifically the region around the town of Buncrana and its surrounding areas on the Inishowen Peninsula. The code is part of the larger 074 numbering plan, which serves much of County Donegal, with the 7497 range allocated to the Buncrana exchange area.
Dialing Formats
For callers within Ireland, the national format is (074) 97xxxxx, where the leading '0' is the trunk prefix. When dialing from abroad, the international format is +353 74 97xxxxx, omitting the leading '0'. The full national significant number (NSN) is typically 9 digits (excluding the leading '0'), comprising the NDC (74) and the subscriber number (97xxxxx).
Coverage and Administration
This geographic code is administered by ComReg, the Irish telecommunications regulator, and is assigned to fixed-line services. It is used by both residential and business customers in the Buncrana area, including the nearby villages of Luddan, Fahan, and Burt. The code is not portable to other geographic areas; however, number portability allows subscribers to retain their number when switching between fixed-line operators within the same exchange area.
Calling Instructions
- Local calls: Within the same exchange, calls may be made using just the subscriber number (97xxxxx). However, it is recommended to use the full national format (074 97xxxxx) for clarity.
- National calls: From elsewhere in Ireland, dial 074 97xxxxx.
- International calls: From abroad, dial your country's exit code (e.g., 00 from most European countries, 011 from the US/Canada), then 353 74 97xxxxx.
Example Numbers
A typical number in this range might be +353 74 9723456. When dialing from the UK, you would dial 00 353 74 9723456 (or use the + symbol on mobile phones).
Overlay and Future Considerations
Currently, there is no overlay code for the 074 area. However, due to the increasing demand for telecommunication services, ComReg has implemented measures to ensure numbering capacity. As of now, the 7497 prefix remains a standard geographic code, and no major changes are anticipated in the near future.
