📍 Geographic Location of Longford
Geographic Overview
The +353 4331 area code serves the town of Longford and its surrounding areas in County Longford, located in the Midlands region of Ireland. This code is part of the National Destination Code (NDC) 43, which covers a broader region in the Irish midlands, including parts of counties Longford, Westmeath, and Offaly.

Dialing Formats
When calling a Longford number from within Ireland, you must dial the national prefix 0 followed by the area code (without the leading +353) and the subscriber number. For example, a local number might be dialed as 043 31 12345 (where 12345 is the 5-digit subscriber number). From outside Ireland, you would dial +353 43 31 12345, omitting the leading 0. It is important to note that the full national significant number (NSN) for Irish geographic numbers is typically 9 digits, excluding the leading 0. In this case, the NSN is 43 31 12345, which is 9 digits.
Caller Instructions
For local callers within the Longford area, it is common to dial only the subscriber number for calls within the same exchange, but for clarity and to avoid misdialing, it is recommended to use the full national format. For international callers, always use the +353 country code and drop the initial 0 of the area code. For example, a caller from the United States would dial 011 353 43 31 12345.
Overlay and Numbering Considerations
As of the latest ITU-T E.164 guidelines, the 43 NDC is not subject to an overlay in the traditional sense, but number portability is available, meaning that a number with the 4331 prefix may be assigned to a service provider other than the original incumbent. This does not affect the geographic significance of the code; it remains tied to the Longford area for routing purposes.
Regulatory and Administrative Context
The area code is administered by ComReg, the Commission for Communications Regulation in Ireland. The 4331 range is part of the national numbering plan, which follows the E.164 standard. Businesses and residents in Longford use this code for fixed-line services, and it is also used for some VoIP services that are tied to a physical presence in the area. When dialing from abroad, ensure you have the correct international access code for your country (e.g., 00 from most European countries, 011 from North America).
