Overview of Area Code 571 (Portlaoise, Ireland)
Area code 571 is a geographic National Destination Code (NDC) assigned to the town of Portlaoise and its surrounding areas in County Laois, Ireland. It is part of the Irish national numbering plan, which adheres to the ITU-T E.164 standard. The full international dialing format for a number in this region is +353 571 XXX XXX (where X represents the subscriber's local number). Within Ireland, callers dial 0571 XXX XXX (including the trunk prefix '0').
Geographic Coverage and Administrative Jurisdiction
The 571 code serves Portlaoise, the county town of County Laois, located in the Midlands of Ireland. The area covered includes the town itself and nearby settlements such as Abbeyleix, Stradbally, and Mountmellick. The code is administered under the jurisdiction of the Commission for Communications Regulation (ComReg), Ireland's national regulatory authority for the telecommunications sector.
Dialing Formats and Caller Instructions
For callers within Ireland, the national dialing format is 0571 XXX XXX. For international callers, the format is +353 571 XXX XXX (or 00353 571 XXX XXX from many countries). It is crucial to omit the leading '0' when dialing from abroad. Local calls within the same NDC area may require only the subscriber number, but this depends on the specific carrier's dialing plan; however, the full national format is always safe.
Overlay Considerations
Currently, there is no overlay code for the 571 area. The code is the sole geographic NDC for Portlaoise. However, as with all Irish geographic codes, number portability allows subscribers to retain their numbers when switching providers, even if they move outside the geographic area, though this is subject to regulatory rules.

- Local callers (within Ireland): Dial 0571 XXX XXX.
- International callers: Dial your country's exit code (e.g., 00 or 011), then 353 571 XXX XXX.
- Important: Do not include the leading '0' of the national significant number when dialing from abroad.
