Is there any standard system for unique property IDs?

2 points·mgav··6 comments

Is there any standard system for unique U.S. property IDs, similar to Zillow's proprietary zpid or the open source (managed by Google) plus codes (https://maps.google.com/pluscodes/)? I'm looking for better options than building my own ID system for a real estate startup. Thanks!

RE: the "Plus Code" (aka "Open Location" code) system, which is lat/lng based and open source (managed by Google), but I don't think it's great for buildings with hundreds of apartments in a single location, such as an apartment tower in NYC.

This post - https://www.dcode.fr/open-location-code - describes how to convert from that code to GPS coordinates (GPS coordinates can be converted to/from a real-language address using the Google Maps Geocoding API (https://developers.google.com/maps/documentation/geocoding/o...)

For example, the zipd for The White House (1600 Pennsylvania Ave) is "84074482_zpid" according to this listing: https://www.zillow.com/homes/1600-Pennsylvania-Avenue-NW,-Wa...

Interestingly, Zillow's value estimate ("Zestimate") is $447 million.

Idea (in progress) to create an open source, uniform, easily-parsed* way to numerically identify every address

*not Plus Codes

I'm not sure yet about how to convert street names into numbers in a logical character-efficient way.

Ideas & feedback welcome!
