However, as with all Irish geographic codes, subscribers may have migrated to VoIP or other alternative services, but the number remains associated with the Thurles geographic area for routing and regulatory purposes.
Caller Instructions
For local callers within the Thurles area, it is possible to dial only the subscriber number for calls within the same exchange area, but this practice is becoming less common as Ireland moves towards full number portability and unified dialing. For all other calls within Ireland, you must dial the full national number including the trunk prefix. For international callers, always use the +353 country code and drop the leading '0' of the area code.
Regulatory and Technical Notes
The 504 code is regulated by ComReg, the Irish communications regulator, and adheres to the ITU-T E.164 international numbering plan. Geographic numbers are typically used for fixed-line services, but they can be ported to mobile or VoIP providers, meaning the physical location of the subscriber may not always correspond to the original geographic area. However, the number retains its geographic significance for caller identification and emergency services routing.
