Two improvements in our latest Fetchify Address Autocomplete release.

Ireland Premium Eircodes now put the locality, the post town the address is actually delivered to, ahead of a redundant county line. And UK retrieve responses now expose a visibility flag so you can see when an address sits in one of our supplementary datasets: Not Yet Built, or Multi-Residency.

Both are live for Address Autocomplete. No change to your request shape.

Ireland Premium Eircodes: locality now takes priority over county

Some Irish place names — Cork and Galway among them — are valid as both a locality (post town) and a county. In Irish addressing, the county is only needed to disambiguate a town when the post town differs from the county name. Where the post town is the county name, the county is redundant and should be dropped, leaving the locality as the place identifier.

For an address in Cork city, the correct form carries the locality and no county line:

Correct Irish address

CORK GROCER'S CLUB

27 COOK STREET

CORK

T12 D92F

Our address builds incorrectly prioritised the county, pushing the place name into a Co. Cork line and leaving the locality blank. So the API would return:

Before — county instead of post town

Cork Grocer's Club, 27 Cook Street, Co. Cork

That's the wrong element: it drops the post town the address is actually delivered to and substitutes a county that, by the rule above, shouldn't be there at all.

With this release, the locality takes priority over the county, so the same lookup now returns the locality populated and no county:

After — locality populated, no county

Cork Grocer's Club, 27 Cook Street, Cork

A comprehensive regression test suite now backs this mapping logic, so the corrected behaviour is locked in and protected against future changes.

If you capture Irish addresses with Fetchify Premium Eircodes, you should now see Cork, Galway, and the other dual-name post towns as the locality, the line Royal Mail and An Post actually deliver to, not as a county prefix.

United Kingdom: additional dataset visibility flag

Retrieve responses now expose an additional dataset visibility flag, telling you when a UK address belongs to one of our supplementary datasets. A retrieve will now indicate whether an address is:

• Not Yet Built — a property that exists in planning/build data but is not yet a completed, occupiable address.
• Multi-Residency — an address covering multiple residential units.

This extra context lets you make smarter decisions downstream — for example, flagging a Not Yet Built property during onboarding, or handling Multi-Residency addresses appropriately in delivery or verification workflows.

Address Autocomplete find behaviour is unchanged. The new signal is on retrieve, so checkout and CRM flows that already fetch the full address can now branch on dataset type instead of treating every UK hit as a finished, single-occupancy property.
