📍 Geographic Location of Tipperary
Geographic Overview
The +353 623 area code is a geographic National Destination Code (NDC) assigned to the county of Tipperary in the Republic of Ireland. This code covers the administrative and historical county, which is divided into North Tipperary and South Tipperary for local government purposes. Key towns and cities served by this code include Clonmel, Nenagh, Thurles, Carrick-on-Suir, and Tipperary Town. The region is located in the province of Munster, in the south-central part of the island.
Dialing Formats
When dialing a number within the +353 623 area code, the national subscriber number is seven digits long. The format is: 0 623 XXX XXX when dialed domestically from within Ireland, and +353 623 XXX XXX when dialed from outside the country. The leading '0' is a trunk prefix used only for national calls and must be omitted when dialing from abroad.
For example, a local call to a number in Clonmel would be dialed as 062 123 456 (if the local exchange uses the 062 short dialing) or more commonly as 0 623 123 456 depending on the specific exchange. However, the standard format for the area code is 623, and the national number is 0 623 123 456. Internationally, you would dial +353 623 123 456.
Caller Instructions
For callers within Ireland: Dial the full national number including the leading '0' (e.g., 0 623 123 456). This applies to both fixed-line and mobile calls.
For callers from outside Ireland: Dial your country's international access code (e.g., 00 from most European countries, 011 from the US/Canada), followed by Ireland's country code +353, then the area code without the leading '0' (623), and the subscriber number. For example, from the US, you would dial 011 353 623 123 456.
Overlay and Numbering Considerations
As of the latest ITU-T E.164 guidelines, the 623 area code does not have an overlay code. However, due to the increasing demand for telecommunication services, the Commission for Communications Regulation (ComReg) has implemented number portability, allowing subscribers to retain their numbers when switching providers. This means that a number with the 623 prefix may be served by any operator, not necessarily the original fixed-line incumbent.
Geographic numbers are primarily used for fixed-line services, but they can also be used for VoIP services that are tied to a physical address. When calling a 623 number, the call is routed based on the geographic location, but with number portability, the actual physical location of the line may differ.
