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
