Is that Eircode
actually right?
Paste an Eircode and this checks it against the published format and character set — the quickest way to catch the O-for-zero and I-for-one mistakes that stop a delivery.
Spaces and case do not matter. Nothing you type leaves your browser.
Looking up a real address?
Address-to-Eircode lookup runs on the Eircode Address Database, which is licensed — we do not hold a copy of it, and any site that claims to have one for free is worth a second look. The official finder is free and authoritative.

Seven characters, in two halves. The first three — the routing key — say which delivery area the address sits in. The last four identify the individual property, and are deliberately unrelated to the neighbours', so that one wrong character does not quietly deliver to the house next door. Unlike a UK postcode, an Eircode is unique to a single address, including each apartment in a block.

Outside Dublin, routing keys are allocated by delivery area rather than by county, so a single key can cross a county boundary. The official finder is the authority on which key covers a given address.
