What is the Tax Map Key Number and how can I find the Tax Map Key Number for my Hawaiian property?
The state of Hawaii uses Tax Map Key Numbers to identify the location of Hawaiian property. It is a five digit number where the first number represents which island the land is on, the second shows the zone of the island, the third indicates the section within a zone, the fourth number is the parcel, and the fifth is the plat where the land is located. You can find your Tax Map Key Number on your property assessment notice, or by contacting the Real Property Assessment Division of your county.
