Data Sources & Attribution

PlatMint normalizes government-accessible property records. We do not own the underlying cadastre. Licence on each coverage row is the starting point; your API terms are the contract.

Counts on the homepage are taken from published parcel / cadastre layers and may be rounded. They are not a delivery SLA.
