Address numbers with leading zeroes

[KCRoadFan]

On my ongoing cross-country Street View journey along US 20, making my way through the Finger Lakes region of New York State, I noticed that some of the addresses along the route in Seneca County, between the towns of Geneva and Waterloo, were displayed with leading zeroes - for example, one house along that stretch had a number of "0342" as opposed to the more normal "342."

Where else throughout the country have you seen address numbers with leading zeroes in them? I know there are some neighborhoods in Portland, Oregon that have them.

Portland started phasing them out last year, as it created issues for first responders, shippers, etc. 

The south waterfront neighborhoods, once with a SW prefix were updated to S.

Williams county Ohio uses leading Zeroes.

Henry county uses a letter prefix on the N-S roads. E-W roads are named A thru W (x y z and diagonal roads). Addresses north of a county road are A123 format.

Not a leading zero per se, but there's a building in Charlottesville numbered "0 Court Square" (as in "Zero Court Square"). The building was once the slave auction site and there's a marker embedded in the sidewalk out front next to the lamppost showing where the auction block was. Apparently the building's historical significance stirred controversy a few years ago when it was up for sale.

Not a zero, but there are some addresses in suburban Grand Rapids that have a leading letter O.  They are on the west side of the Kent/Ottawa county line; O is for Ottawa County.  For example, there is a business called Red Hen Toys at O-78 Leonard St NW.  In theory there could also be a 78 Leonard St NW in downtown GR.

Not a 0 but Flint, MI has a bunch of addresses that are like G4300 Miller Road.

Unincorporated addresses in Kane and DuPage Counties, in the western expanses of the Chicagoland area, are marked with a number in the format of ##L###, where L is a direction.  The numbers are based on the street grid of the city of Chicago.  Instead of saying "38527W," the addresses read "38W527."  Since the equator of Chicago (Madison Street), or the 0N/0S line, extends due west through the middle of Kane and DuPage Counties, addresses along north-south roads very near that equator have a zero before the letter indicating the direction.

The house where I lived for the first five years of my life had "5S146" for an address.  It was read aloud as "Five south one four six" or "Five south one forty six."

The east-west addresses in Kane County are in the 30,000s and 40,000s, but the second number will lead with a zero if you get just west of a meridian marking an even thousand.

First responders should have been trained to compensate, but the conversion of the negative SW to the official extension of South quadrant (from Oregon City/Beavercreek/Redlands) is a good idea.
