How to use the Ireland postcode map
The directory groups 139 postcode-locality records into 15 broad IE prefix zones. Freight planners can use these prefixes to identify collection and delivery regions, compare locations and communicate a general service area.
Select a zone for its reference locality and map position. A prefix is useful for early planning, but the complete postcode and delivery address should always be confirmed before dispatch.

EuroPostcode uses open postcode-locality records for geographic orientation. Postal codes change and some special, organisation or PO-box codes may not be represented. Confirm a delivery code with the recipient or the relevant postal operator before dispatch.
