Capture, Validate & Standardise accurate address data for Ireland

There are roughly 800,000 non-unique addresses in Ireland – over 35% of properties share their address with at least one other property. This creates major difficulties in postal efforts, especially in rural areas, and often turns a simple delivery into a scavenger hunt. To help individuals and businesses overcome delivery challenges, the Eircode was introduced as Ireland’s National Postcode System, helping make postal deliveries more efficient.

Melissa’s Eircode Address Validation service captures accurate address data using Ireland’s advanced postcode platform, proven to be the most effective way to verify exact locations in the Republic of Ireland.

  • Access to ECAF & ECAD Eircode Database for Ireland’s advanced postcode platform
  • Enhance communication with customers to increase deliverability across the Republic of Ireland
  • Standardise incomplete addresses to meet Eircode’s formatting rules
  • Add Geolocation Coordinates for pinpoint location intelligence in Ireland

What is Eircode?

Until fairly recently, Ireland was one of the few developed nations without a postcode system. Approximately 800,000 addresses and over 35% of properties shared their address with at least one other property, meaning no house name or number existed for the majority of these premises.

In 2015, Eircode was introduced as Ireland’s brand-new advanced postcode system. Like most countries’ postcode structures which define a cluster of addresses, Ireland’s game-changing system gives the ability to locate every individual address or premise in the country by using a single code at the end of each address.

This ultimately removes the guesswork of finding addresses, not just good news for the Irish but a grand development for any business that holds Irish address data.

Frequently Asked Questions

Postcode and ZIP Codes are strings of numbers and letters that represent groupings of people in specific geographic areas; while they offer accurate insight to areas, they often cover multiple dwellings, which can make finding a customer’s correct address more challenging if houses are named rather than numbered.

The advantage of Eircode gives every address in Ireland its own unique number used to identify individual property and businesses. This is particularly handy when dealing with addresses in remote or newly built areas.

Eircodes are automatically assigned to all postal addresses in Ireland and added to the end of each address so residents don’t need to apply for an Eircode. The use of Eircode also isn’t mandatory, but many businesses offering logistics or shipping correspondence to Ireland are now asking for Eircode as a requirement.

Eircodes are assigned every quarter, currently in the months of February, May, August and November. When an Eircode is assigned, it is automatically available on the Eircode Finder and notification is posted to the address notifying the occupant of the Eircode.

Automatic updates are also followed on to licenced businesses and organisations who license the Eircode database.
