Step 2.
7015 Rita Ave, Huntington Park, CA 90255


Step 3.
6174 Maywood Ave, Huntington Park, CA 90255


Step 4.
Now its address becomes 3511 randolph

Step 5.
Because of locator does not allow more than one layer for Address ROLE, so have to add these missing point into original address layer

Step 6.
mark these kind of fix as FIX in here, so you know it is missing address in the future.

Step 7.
re-run locator

Step 8.
because do not map apartment number, so unit number and unit type will be none.
here will no subaddress option shows. make sure locator configured like this

Step 9.
fixed

Step 10.
fixed.

Step 11.
alternatively, if you turn on fake street address, it will cover these issue. Because if locator did not found above number in address point layer, it will go to street center line layer, use street segment number range to estimate a location create a fake address.
So in this condition, you would think it is a valid address, in fact it is not.
By default setting, you would not know it is fake address (from street number range estimated) or it is a real address (from address point layer).
However, by adding the work around, you can tell the difference
left is default setup, right is adding work around,
on left, you don't know which is fake address, which is real.
on right, street name with parenthesis means, it is unreal address from street line layer.
you can see only 3090 slauson is real address, others are all fake address.

Step 12.
if you turn on fake street address, locator will cover the missing address, means, even missing, locator can still estimate a fake address popup. So this way, even 911 caller report a wrong house number, we still can find him.
for example, 7107 pacific, business is already closed, POI list don't have this address.

Step 13.
LA county have this parcel as 7103. One parcel could have multiple address.
If this business closed, then 7107 will not show on POI list, not on County's address list.
However, in the past, does have 911 caller report incident on 7107, we have historical record.
Now we do need 7107 to be validate as good address, even it is not good one now.

Step 14.
not a good real address, not on county's address list, no a POI address,

Step 15.
not a real address now, maybe in the past, it was a good address, now google think this address is 6877
google is wrong, obviously google did not get 6877 from la county. La county says this parcel is 2814.

Step 16.
google is wrong, obviously google did not get 6877 from la county. La county says this parcel is 2814.

Step 17.
google street view says 2814

Step 18.
la county says 2814
