Property Reference Number (PRN) is a unique reference number assigned to each property.

You can obtain the Property Reference Number (PRN) of the property free of charge using the "Search Land Register - Street Name Section", "Search Land Register - Development Name Section" or "Search Land Register - Lot Details Section" in the IRIS Online Services. The PRN will be shown together with the address information in the land register selection screen and order lists.

You may use the PRN to search for your property using the "Search Land Register - Property Reference Number (PRN) Section" in a more easy and convenient way.
