📍 Geographic Location of Portlaoise
Overview of Area Code 5786
Area code 5786 is a geographic National Destination Code (NDC) within the Irish telephone numbering plan, assigned to the town of Portlaoise in County Laois. It is part of the larger 057 geographic area, which was introduced in 2001 as part of a nationwide restructuring of Irish area codes. The 057 area covers the midlands region, including Portlaoise, and is administered under the Commission for Communications Regulation (ComReg) guidelines.
Geographic Coverage and Administrative Jurisdiction
The 5786 prefix serves Portlaoise, the county town of County Laois, located in the midlands of Ireland. The area code covers the town and its immediate environs, including nearby towns such as Stradbally and Mountmellick, which are also within the 057 geographic area. Portlaoise is an important administrative and commercial hub, with a population of approximately 23,000 (as of 2022). The code is used for fixed-line telephone services, typically provided by traditional PSTN operators and VoIP providers that offer geographic numbers.
Dialing Formats
For callers within Ireland, the national dialing format is 057 86xxxxx, where '057' is the trunk prefix and '86' is the local exchange code. The full national number is 9 digits (excluding the leading '0'), and the subscriber number is 5 digits after the area code. For international callers, the format is +353 57 86xxxxx, dropping the leading '0' from the trunk prefix. For example, a local number might be dialed as 057 8623456 from within Ireland, and as +353 57 8623456 from abroad.
Overlay Considerations and Number Portability
There is no overlay code for the 057 area; the 057 NDC is the sole geographic code for the region. However, due to number portability, a number with the 057 86 prefix may be assigned to a service provider other than the original operator, and in some cases, it may be used for non-geographic services (e.g., VoIP) if the subscriber has moved. Callers should be aware that the geographic location of the number does not necessarily reflect the physical location of the called party, especially if the number has been ported.
Caller Instructions
For local callers within the 057 area, it is possible to dial the local number without the area code in some cases, but it is recommended to always use the full national number to avoid misdialing. For callers from other parts of Ireland, dial 057 86xxxxx. For international callers, dial +353 57 86xxxxx. Ensure that you replace 'xxxxx' with the actual 5-digit subscriber number.
