Step 1.
county address system is tax oriented, not accurate enough for 911 police use.
This is county wide systematic issue, it is everywhere cross the county
I show you one example,
use google address collecting tool, 6793
Step 2.
google address collecting tool, click any where on map, show nearby address point,
model 6793 is helping you to reveal all possible address from google address database.
3479 Hope St is a valid address in google database

Step 3.
but county address system show only one address 7621 which is different from 3479
Step 4.
why is 7621 ? check county parcel tax map,
county tax parcel only record one address 7621 for this whole parcel,
you can see there are 3 building in this parcel, from google address tool, we know there are 6-7 address in this single parcel.
county address system is tax oriented, only record 7621, missing all the other 5 address

Step 5.
7617 is missing
Step 6.
7619 is missing
Step 7.
7625 missing
Step 8.
3473 is missing, this building seems like owner build extra structure in backyard for rent.
Step 9.
3479 is missing, this building seems like owner build extra structure in backyard for rent.
Step 10.
At least 5 missing address from county address system.
For tax collecting, 7621 is good enough to mail the tax bill to owner home. Good enough to let owner pay property tax.
For 911 police use, 5 missing address actually are needed.
Otherwise 911 dispatch and police officer will have hard time to find them.
Would apple address database out perform than google ?
Apple Vs Google
who is winner ?
use model 8130 for apple
https://transparentgov.net/json2tree/esri/server/folder.html?org=https%3A%2F%2Fpublic.gis.lacounty.gov%2Fpublic%2Frest%2Fservices&url=https%3A%2F%2Fpublic.gis.lacounty.gov%2Fpublic%2Frest%2Fservices&arcgis_online_token=&timeout=9000&select_folder=17&select_layer=19&select_folder_text=Political_Boundaries+%3Csup%3EMapServer%3C%2Fsup%3E&select_layer_text=19+%26%23x21E2%3B+City+Boundaries+%3Csup%3EFeature+Layer%3Csub%3E+esriGeometryPolygon%3C%2Fsub%3E%3C%2Fsup%3E
Step 11.
3477 revealed by apple address database,
even Google failed to record 3477,
Only apple map record 3477,
So far in 2026, some times Apple map even more accurate than Google.
Apple is catching up, back to 2018, apple is a way behind google.
https://transparentgov.net/json2tree/gateway/google-click-map-to-get/apple-show-address.html?layer_id=19&url=https%3A%2F%2Fpublic.gis.lacounty.gov%2Fpublic%2Frest%2Fservices%2FLACounty_Dynamic%2FPolitical_Boundaries%2FMapServer&layer=City+Boundaries&panto=0¢er_lat=33.96791196511472¢er_long=-118.20429053273948¢er_zoom=20
Step 12.
3477, can be confirmed by check google street view.
Owner print 3477 on wall
Step 13.
How is ESRI's new 2024 release location platform says about this address?
Would it more accurate than google and apple?
Google and Apple is top runner so far,
let's check out how ESRI's location platform runs.
use model 5126
https://transparentgov.net/json2tree/esri/server/folder.html?org=https%3A%2F%2Fpublic.gis.lacounty.gov%2Fpublic%2Frest%2Fservices&url=https%3A%2F%2Fpublic.gis.lacounty.gov%2Fpublic%2Frest%2Fservices&arcgis_online_token=&timeout=9000&select_folder=17&select_layer=19&select_folder_text=Political_Boundaries+%3Csup%3EMapServer%3C%2Fsup%3E&select_layer_text=19+%26%23x21E2%3B+City+Boundaries+%3Csup%3EFeature+Layer%3Csub%3E+esriGeometryPolygon%3C%2Fsub%3E%3C%2Fsup%3E
Step 14.
use model 5126, click the building roof,
esri only reveal single one address which is 7625
missing all 6 address previously revealed by google and apple,
making ESRI the worest address database(location platform) among other competitor as of 2026.
Esri's location platform is 1.2 year old, NOT made in house, ESRI bought address database from 3rd party company named four-sqaure.
Google's address database made in house, have 20 years history.
