At BeenVerified, our goal is to provide our customers with the most accurate and comprehensive property information. However due to way our data is sourced, sometimes there are gaps in it. Apartment buildings are one example: Some apartment buildings have multiple addresses associated with a single location and in some of these situations, our data providers do not differentiate between the two. This is something BeenVerified is working on and we hope to have what you are looking for in the near future. If you happen to find an address that does not exist in our database, please let us know and we will do our best to include it in the future.
