If you've just moved to Ireland or you're filling out an online form, you'll quickly run into a box asking for your Eircode. If you have no idea what that is or where to find yours, this guide clears it up in plain language.
An Eircode is Ireland's national postcode system. Unlike most other countries where postcodes define clusters or groups of addresses, every single home and business in Ireland gets its own unique Eircode. That sounds minor, but it matters when you're ordering takeaway, booking a taxi, getting a parcel delivered, or signing up for any service that needs to verify your address.
An Eircode is Ireland's national postcode system. It is a code of seven characters made up of letters and numbers, with two parts: a 3-character routing key for the area and a 4-character unique identifier for the individual address. A typical Eircode looks like A65 F4E2.
Every house, flat, and business address in Ireland has its own Eircode. You can find yours for free using the official Eircode Finder on the Eircode website, which provides accurate address data and location coordinates.
Every Eircode consists of two parts:
So in A65 F4E2, the "A65" routing key tells you the general delivery area, and the "F4E2" unique identifier pinpoints the exact location of the property.
This system makes Eircode different from postcode systems in other countries, where postcodes define clusters of addresses instead of individual properties. According to Eircode providers, over 35% of addresses in Ireland are non unique addresses, which is why a unique code was necessary to accurately identify every building.
A quick comparison if you've moved here from another country:
| System | Country | Format | Coverage |
|---|---|---|---|
| Eircode | Ireland | Seven characters, letters + numbers | One per individual address |
| Postcode | UK | 6-7 characters, letters + numbers | Groups of nearby addresses |
| Zip code | US | 5 or 9 digits | Whole neighbourhood or district |
| PLZ | Germany | 5 digits | Whole town or district |
| Postal code | Pakistan | 5 digits | Whole town or sector |
Eircode was introduced in Ireland on 28 April 2014 as the national postcode system. Unlike other countries, where postcodes define clusters or catchment areas, Eircode consists of a unique seven-character code assigned to each individual address. This precision has improved mail delivery and other services across the country.
Ireland was the last country in the OECD to implement a national postcode system. Until 2015, deliveries to rural Ireland often meant phoning the driver and giving directions like "turn left at the church and look for the blue gate."
Roughly 800,000 addresses in Ireland have no house number or name. These are mostly in rural townlands. Before Eircode, deliveries to these addresses were guesswork. After Eircode was introduced and the database created, every one of those addresses was assigned a unique Eircode, which helps postal services, emergency responders, and businesses accurately identify and locate properties.
You can find any Eircode in Ireland for free in a few seconds.
Go to the official Eircode Finder website, where you can search by postal address or use the map to pinpoint the property. The Eircode Finder is updated quarterly with new data from An Post GeoDirectory and other sources, ensuring accuracy.
The Eircode Finder allows you to zoom into any building on the map and click to see the Eircode. Popular mapping software and online tools also support Eircodes, enabling you to search and navigate with ease.
If you've been at your address for a while, your Eircode is displayed on bills, letters, and official mail from An Post. New occupiers of newly built properties receive a letter notifying them of their Eircode once their address is added to the national database.
If you're renting or using a commercial building, your landlord, property management office, or business department will have the contact details including the Eircode.
Use your Eircode in two main places:
Place the Eircode at the bottom of the Irish address, just below the county. For international post, include the Eircode between the county and country details. Example:
Eircodes are not used for PO Box addresses.
Many Irish websites have a dedicated Eircode field. Some online shops and service providers use Eircode to improve delivery efficiency and address verification. Entering your Eircode can autofill your full postal address, saving time and reducing errors.
Everyday situations where you'll be asked for your Eircode include:
