The map shows our Ireland postal code coverage with major cities and postal code distribution.

Ireland's Postal Code Format

Ireland uses an “Eircode” system, which is a seven-character alphanumeric format like A99 AAAA, featuring an alternating letter-digit-digit pattern followed by a space and four letters. This system is alphanumeric, unlike the purely numeric US ZIP codes. Ireland has 139 postal codes covering 3,380 regions and 51,780 towns.

  • Postal Code Format: A99 AAAA

    • Seven-character alphanumeric format (letter–digit–digit, space, four letters)
    • Two-part structure: Routing Key (first 3 characters) + Unique Identifier (last 4)
    • Extremely granular—unique down to individual addresses
    • 139 postal codes covering 3,380 regions and 51,780 towns

    Regional Examples:

    • D02 X285 - Dublin (Leinster)
    • T12 A2YT - Cork (Munster)
    • H91 E2KT - Galway (Connacht)
    • V94 V8X4 - Limerick (Munster)

  • Structure of Postal Codes

    • Format: A99 AAAA (e.g., D02 X285) with a mandatory space.
    • Hierarchical levels: Routing Key (first 3 characters) defines the area; Unique Identifier (last 4) specifies the exact building or address.
    • Key challenges: Full dataset is proprietary and license-restricted; third-party datasets typically include only routing keys.

  • Management & Authority

    • Primary postal authority: Eircode, operated under government contract.
    • Update frequency: Codes assigned continuously for new addresses; redistribution subject to strict licensing.

  • Addressing Standards

    • Common address format: Street name + house/building number, locality, county, Eircode.
    • Administrative divisions used: Postal localities (primary, secondary, tertiary) and “post counties,” which may differ from official administrative counties.

  • Special Characteristics

    • Eircodes are precise to each building, making them one of the most detailed postal systems globally.
    • Licensing restrictions limit access to full codes; routing keys are often the only usable component for external datasets.
    • Bilingual context (English and Irish) introduces variations in locality names and address searches.

Frequently Asked Questions

Ireland does not use traditional zip codes. Instead, it uses the Eircode system. Each Eircode is a unique identifier for every address in Ireland, comprising a seven-character code.

Dublin, Ireland, uses the Eircode system instead of traditional zip codes. For example, the Eircode for Dublin city center might be D01, followed by four characters unique to the specific address.

Yes, Dublin 12 is a postcode district within the Eircode system. It covers areas such as Crumlin, Drimnagh, and Walkinstown, providing a more specific identification for locations within Dublin.

The United Kingdom uses a system of postal codes rather than zip codes. These codes vary by region, with examples including SW1A 1AA for Buckingham Palace in London and EH1 1BQ for a location in Edinburgh. Each postcode area helps to identify specific locations within the UK.

Ireland uses the Eircode system as its national postcode system. Introduced in 2015, Eircode assigns a unique code to every residential and business address, enhancing mail delivery and location identification.

The Irish government regulates addresses through the Eircode system, ensuring that all postal addresses are standardized. This regulation helps in efficient mail delivery and accurate geographic identification.

Postal addresses in the Republic of Ireland are essential for mail delivery. Each address includes an Eircode, which precisely locates the delivery point, facilitating faster and more reliable mail distribution.

Business addresses benefit from using Eircode by ensuring accurate delivery and easy location mapping. This system aids businesses in logistics, customer deliveries, and location-based services like Google Maps.

Ireland was the last country in the OECD to adopt a national postcode system. The introduction of Eircode in 2015 modernized postal address management and improved services related to logistics and geographic information systems.
