Taiwan Address Number and Building Database is an online information service that helps users look up property and land records by street address. Visitors can search an address to find associated building identification details and, where available, land parcel numbers, construction permits, and occupancy permits. The site organizes address searches across Taiwan’s cities and counties, from Keelung and Taipei to outlying areas such as Penghu, Kinmen, and Lienchiang, and provides quick search tools alongside lists of frequently viewed addresses.

The service also offers access to land-section map and parcel-number searches, real estate transaction price registration searches, and construction and occupancy permit searches. Its information is periodically compiled from public sources, including Taiwan’s Department of Land Administration. The website states that results are intended as a reference for illustrating land locations and are not legally authoritative; users should rely on official transcripts issued by the relevant land office for verified records. The site provides a privacy policy, cookie policy, and contact email for inquiries.
