📍 Geographic Location of Killenaule
Geographic Overview
The +353 5291 dialing code is a geographic National Destination Code (NDC) assigned to the town of Killenaule and its surrounding areas in County Tipperary, Ireland. This code forms part of the national numbering plan administered by ComReg, the Irish telecommunications regulator. Killenaule is a small market town located in the south-east of County Tipperary, near the borders with County Kilkenny and County Waterford. The code covers Killenaule itself, as well as nearby villages and townlands such as Mullinahone, Ballingarry, and portions of the surrounding rural hinterland.
Dialing Format
When calling a landline in Killenaule from within Ireland, subscribers must dial the national prefix 0 followed by the NDC and the subscriber number. The full national number format is (052) 91 xxx xx or more commonly written as 052 91 xxx xx. However, the international format, as used by callers from outside Ireland, is +353 52 91 xxx xx (or +353 5291 xxx xx when the NDC is considered as a whole). For example, a local number might be 052 91 12345; from abroad, dial +353 52 91 12345.
It is important to note that the NDC for Killenaule is officially 052 in the national numbering plan, with the following digits 91 forming part of the subscriber number. However, for clarity and routing purposes, the code is often presented as 5291 in international contexts. The subscriber number length is typically 5 to 7 digits, resulting in a total national significant number (NSN) length of 9 digits (excluding the leading 0).
Geographic Coverage and Administration
Killenaule is part of the administrative county of South Tipperary, which was amalgamated into the single County Tipperary in 2014. The area is served by traditional copper-wire PSTN infrastructure, as well as modern fiber-optic and VoIP services. The code is classified as a geographic number, meaning that the tariff for calls to this number is based on the caller's location within Ireland, and the number is associated with a fixed physical address.
Caller Instructions
- Local callers (within Ireland): Dial 052 91 xxx xx (including the leading 0).
- International callers: Dial your country's exit code (e.g., 00 from most European countries, 011 from North America), then 353 52 91 xxx xx (omit the leading 0).
- Mobile callers within Ireland: The same national format applies; there is no need to add an area code if dialing from a mobile, but the full national number must be used.
Overlay and Number Portability
As of the latest ComReg updates, there is no overlay code for the 052 area. However, number portability is available, allowing subscribers to retain their geographic number when switching to a different fixed-line operator, including VoIP providers. This means that a number with the 052 91 prefix may not necessarily be physically located in Killenaule if it has been ported to a non-geographic service, but the number remains associated with the geographic tariff zone.
