Why is one New York city mostly verified and another isn't?
It reflects how each listing reached us. Listings pulled straight from the license register verify at very high rates; listings that came from permit filings or public business profiles stay unverified until we can tie them to a license. A low share is a data gap, not a warning about the city.
