Major shipping & fulfilment merchant to make Eircode a mandatory requirement for deliveries within the republic of Ireland starting July 2023

Prior to the introduction of Eircode in 2015, Ireland was one of the few developed nations without a nationwide postal code system. Given that more than 35% of Irish addresses were shared with at least one other property, locating, and identifying addresses both online and offline presented a significant challenge.

Postal workers were required to maintain a manual record of family names and property addresses in small towns and townlands in order to facilitate successful deliveries. This local knowledge is difficult for larger courier services to replicate.

The Central Statistics Office reports that over 80% of Irish residents make online purchases, resulting in a surge in deliveries. The absence of Eircode, which provides precise location information, makes sending and receiving orders extremely problematic, creating obstacles for both businesses and consumers.

A major shipping & courier merchant who is undisclosed has mandated the use of Eircode for all shipments entering the Republic of Ireland from 2 July 2023. It is probable that other courier services will follow suit in an effort to enhance first-time delivery rates.

How does Eircode Work?

Eircode is made up of two parts: a routing key and a unique identifier.

Routing Key

Unique Identifier

Defines a main town’s span of delivery

Completely unique to one address




The delivery area or routing key is specified by a three-character routing key in the Eircode system. Meanwhile, a four-character unique identifier distinguishes one address from another and is specific to that address.

Although similar in appearance to the UK's Royal Mail postcode system, the Eircode system has a different format. Unlike other countries where postcodes are used to identify a group of addresses in a specific area, Eircodes are used to identify a single address. Each residential and business address in Ireland has its own unique Eircode identifier, resulting in over 2.2 million distinct Eircodes.

Eircode for eCommerce

Eircode offers manifold advantages for the community, enterprises, and governmental agencies. As DHL Express has made Eircode information mandatory, it is imperative for online shopping portals to amass and authenticate Eircode details to guarantee that their chosen courier services will take the shipments without imposing supplementary address amendment fees.

Some of the primary benefits are:

  • Minimises cart abandonment with automatic address filling.
  • Accelerates, precise, and uniform address acquisition and authentication.
  • Enhances the rate of successful initial deliveries.

Eircode is available in two data product options, the first option being ECAF (Eircode Address File) which is the base reference for all address points containing 2.2 million data points with Eircode’s and USP Postal addresses.
