Addressing outside of Great Britain

Boost your marketing ROI

AddressBase Islands means you can run successful national campaigns - or build awareness in new markets, targeting households in properties converted into flats, for example.

Available in two versions

AddressBase Islands is available in two versions, allowing you to attach it to your existing GB AddressBase product, whether that's AddressBase Plus or AddressBase Premium.

Straightforward licensing

We offer the same style of licence for AddressBase Islands as existing AddressBase products. This ensures you can use your AddressBase Islands data in a consistent way across the United Kingdom and Crown Dependencies.
