Unlike many other countries, Ireland does not utilize a comprehensive national postcode system. Instead, postal addresses rely on county names and locality details for mail delivery. This means that a specific numerical or alphanumeric sequence corresponding to the town in County Mayo is not used.
The absence of individual postal codes necessitates a detailed and accurate address to ensure efficient mail sorting and delivery. Precise location information within the town becomes vital. This system has historical roots in the country’s infrastructure and population distribution.
