What is an Eircode?

Ireland’s postcode network, Eircode, was established in July 2015. A seven-character alphanumeric postcode is known as an Eircode. Every Eircode is specific to a mailing address and its area. 

 

In Ireland, almost 35% of properties share their address with at least one other residence, making it very difficult to locate a specific address. Unlike in other nations, where postcodes establish a group of addresses, each home and commercial postal address in Ireland is allocated an individual Eircode, aiding in address verification

 

Eircodes, like postcodes in other nations, aid the shipping and postal industries in locating accurate addresses. The Routing Key, the first three characters of the Eircode, specify the postal region associated with a building or property’s postal address. In Ireland, there are 139 separate postal regions. These postal areas are not limited to a single county and may cross over county lines. 


How do Eircodes work? 


A Routing Key and a Unique Identifier are the two elements of an Eircode. Three characters make up the Routing Key. The significant post town associated with a business or property’s postal address is identified by this sequence of numbers and letters, facilitating address lookup. All Eircodes issued to locations within that postal region have the same Routing Key characters. 

 

Each unique identification is distinct and specific to your residence or business. They aren’t in any particular order. This is to avoid a situation where a new building is built between two old ones, and the code sequence is disrupted, necessitating the changing of all Eircodes in the region. 

 

Except for the postal districts in Dublin, which have had their current postal codes translated into a routing key format such as D03, D12, and D22, the letters are not related to a county or city designation.


What is the difference between Eircode and Postcode?   


Postcodes and ZIP codes are numerical and alphabetical sequences that symbolise groups of people in specific geographical locations. Companies can use postcodes for a variety of key use cases because they are a strong resource of demographic data. 

 

However, they frequently encompass several dwellings, making it more difficult to locate a customer’s proper location if homes are named rather than numbered. This challenge underscores the importance of address verification

 

Eircode, on the other hand, assigns a unique identity to every property in Ireland, making it easier to locate residences and companies, especially in rural areas. 

 

Why use Eircodes for deliveries in Ireland? 

 

The increase in online shopping is excellent news for online retailers, but with a higher rural population than the EU average, precisely locating clients in Ireland can be difficult. Any company delivering goods in Ireland must have Eircode data. Those who use the address lookup software with Eircodes add-on to collect clients’ addresses should expect to see:  

 

A reduction in failed deliveries  

It’s obvious that incomplete or inaccurate delivery details will result in failed deliveries. Eircode gives another level of concrete data to help drivers deliver correctly and on time, hence enhancing the brand image. 

 

Customer experience  

If your address lookup software can’t locate their address, Irish customers are likely to abandon their transaction. Making the checkout process as simple as possible and providing extra data sets like Eircode would not only improve the customer experience, but also satisfy customers and increase conversions for your brand. 

 

Reduced costs 

As a business, providing proper delivery details to your courier operator ensures that you won’t be held accountable for unsuccessful deliveries. Some couriers will only cooperate with retailers who supply confirmed addressing data or will give them a discount if they do.

An article in Ecommerce News recently put a number to something every online retailer dreads: lost parcels. In Q4 2024 alone, European ecommerce retailers lost €500 million in revenue due to 3.72 million undelivered parcels. That’s roughly €145 per parcel in direct and indirect logistics costs. And while the official rate of “lost” parcels is just 0.06%, the reality – accounting for misdelivery, theft, and reporting gaps – is likely closer to 0.7%. That’s 1 in every 143 parcels. The Hidden Costs of a 'Lost' Delivery For enterprise-scale ecommerce operations, the implications scale fast: Lost product and packaging costs Repeat fulfilment and reverse logistics Customer service team time and refunds Increased churn and checkout abandonment Damage to brand reputation and online reviews So Why Are Parcels Going Missing? Many issues originate in the last mile of the delivery process. The root cause is often poor data quality: Incomplete or inaccurate delivery addresses captured at checkout Manual amendments to address fields by warehouse or courier staff Ambiguous delivery locations (e.g., "front porch") Lack of precise geolocation data for drop-off Inadequate or unverifiable proof of delivery Some losses are unavoidable, but most stem from gaps in ecommerce data validation and fulfilment process transparency. What Retailers Can Control with Smart Logistics Data While you can’t eliminate theft or accidents, you can reduce missed deliveries and failed first attempts through better data validation and delivery insights: Real-Time Address Validation at Checkout Fetchify’s ecommerce address validation tools connect directly with official data sources including Royal Mail PAF and the Multiple Residence dataset. This ensures accurate delivery details for apartment blocks, HMOs, student housing, and more. Unlike generic autocomplete tools, this is verified delivery point data. Rooftop-Accurate Geocoding for Pinpoint Delivery Fetchify’s Rooftop Geocodes assign precise latitude and longitude to verified addresses – helping carriers reach the exact doorstep, not just the postcode centroid. Proof of Delivery with Location and Time Stamping Our data solutions integrate seamlessly with POD technologies, supporting timestamped, geo-tagged delivery images. Customers can also submit geo-located photos during disputes, enabling faster, fairer resolutions. Map-Based Address Confirmation for Shoppers By embedding a zoomed-in map in the checkout process, ecommerce brands allow customers to visually confirm their delivery location. This prevents ambiguous or misentered addresses from the start. Audit Trails and Address Change Tracking Fetchify tracks address field edits and changes across the fulfilment chain, helping to pinpoint where a delivery went wrong and maintain data accountability. Marginal Gains. Major Ecommerce Impact. Smart logistics and address data validation might only reduce parcel loss by fractions of a percent – but the impact is huge: A 0.1% improvement = thousands of saved parcels = millions in recovered revenue Fewer failed deliveries = less pressure on customer support teams Accurate addresses = better first-time delivery success and lower last-mile costs Conclusion: Delivery Accuracy is a Data Challenge Lost parcels aren’t just a logistics challenge. They’re a symptom of poor data validation in ecommerce. From checkout to doorstep, the journey must be powered by precise, verified data. Fetchify helps online retailers solve this problem with address validation, geolocation, and enhanced fulfilment transparency. If you want to stop asking “Whose front door is this?” – start with smarter ecommerce data. Want to improve delivery success and reduce failed parcels?
