What is a KAEK and how to read it
The KAEK (Κωδικός Αριθμός Εθνικού Κτηματολογίου — National Cadastre Code Number) is the unique code under which every land parcel is registered in the Hellenic Cadastre. What a tax number is to a taxpayer, the KAEK is to a property: you find it on contracts, on the E9 tax form, on cadastral extracts and in every transaction involving the property.

KAEK extensions
For divided properties (apartments, vertical properties), the parcel's 12-digit code is extended with extra digits that identify the horizontal or vertical property. Special areas such as roads and streams have a KAEK containing the letters “ΕΚ” — see the special categories.
