Yes, I know that so far the subject line is not specifically being address right off the bat. I changed the subject line after seeing where this point of blog entry inquiry took me. Stick with it to see where it goes.

The lowest discrete level is County areas. It could go lower than that governmental division? How low could it go before privacy required a limit? ZIP code perhaps?
This is a GIS Map that I often use as a point of entry to discover Deschutes County Assessor information. It drills down on a map to the individual owner property tax account. The map can be enlarged to show individual properties from which to select to see all property tax information related to that property (a large amount of info!).

Whoops! What has happened to the Deschutes county Dial Map? On my screen it shows only as a narrow sliver not a full screen map! Perhaps it is a temporary glitch?
Back to the usefulness of a GIS map as a point of entry to information research.....
Might the SNAP map be presented on a more precise geographical level? ZIP Code? It depends on how recipients receive their SNAP qualification/authorization.
The city of Bend is an example.

My Zip Code is 97703-xxxx. Why not give my actual ZIP+4? Because Google searching on my full ZIP+4 reveals my name, street address and that of my next door neighbor as well. It also reveals the two names of previous occupants. One sold me the house 30 years ago. Another was the only renter of my home for a year! If the full ZIP+4 identified a carrier route there should be many more returns on the Google Search! WTF?
That cannot identify my specific house. I never know what that additional 4 digits meant. Those additional 4 digits are ZIP+4. Today I learned it is the carrier route ID Number used for sorting purposes. My street address does identify my house. My name on the letter (other than occupant) identifies me or any other resident in the house receiving a letter intended for them.
The Bend ZIP Code Map shows three ZIP codes for Bend. Bend used to be 97701 now there are three ZIP codes that cover a much larger area than the city limits of Bend but all intersect at Bend to divide the city itself into 3 areas.
The same commercial .com site above that gave me the Bend map of 3 Zip Codes will sell me a disc with all the ZIP+4 codes for the entire USA!
https://www.zip-codes.com/zip-plus-4-database.asp
Where is a map that shows the geographical area of ZIP Code 97703 with added information related only to the basic ZIP Code number?
YES. Amazing! Another commercial .com site can add information.

Wow!
What started out as thoughts to get a closer look at where recipients of SNAP are located lower than the county level turned into a serendipitous discovery of a more granular location system in the United States Postal System addressing!
How many ZIP+4 codes are there in the Bend 97701, 97702, 97703 Zip Code areas.
This is really narrowing things down!
Hmmm... this is getting interesting!
What might this Census data reveal if it was overplayed on a GIS map?

This is getting into something I do not know how to do but someone must have done it for me..other than a .com site that wants to sell it to me? It is open source government information.
What exactly is this Census Bureau TIGER thing all about that seems to have a connection to ZIP+4?
https://www.census.gov/geo/maps-data/data/tiger.html
Google searching on my own ZIP+4: 97703-xxxx reveals that there are only 3 valid search returns.
One for the previous owner that sold me the house 30 years ago. One for my next door neighbor.
This explanation of ZIP+4:
http://blog.stamps.com/2017/03/17/whats-the-zip-plus-four-for/
"You may have noticed the extra appendage of numbers added to a ZIP code called the plus-four, ZIP + 4, or add-on code. What is it for? The USPS considers the five-digit ZIP plus those additional four digits to be the most complete kind of delivery code. Introduced in 1983, the plus-four is a helpful ally in the ongoing drive for even more efficient delivery and sorting.
relationship between ZIP+4 codes and Federal Information
Processing Standard (FIPS) county codes. The file allows users
who have assigned ZIP+4 codes to their address files to obtain
county data at the ZIP+4 level."

Holy Smokes!
Does the right hand of government data not know what it reveals when joined by relationship to the right hand of government data? This is a situation ripe for data mining and information exploitation!

Returning to the beginning of this blog entry:
The top link demonstrates the information value of a map point of entry to display relative geographical information. It shows information at the county level. More precise information would be presented if it was shown at a lower geographical level. Zip+4 for example. The first two digits of Zip+4 show a sector the second digits a section. A section appears to be s street or similar area. My street with 98 addresses for example. That is a very small area and nay reveal private information. The size of a sector however would likely anonymize any specific personal privacy information.

Introduced in 1983, the plus-four is a helpful ally in the ongoing drive for even more efficient delivery and sorting.
What do the numbers mean?
What is the breakdown of the plus-four and what do the numbers mean? The first two numbers of the plus-four identify the larger area known as the sector. The last two identify the segment. Segment and sector are actually terms that identify very specific geographical areas that pinpoint more than just a numbered house on a street. As explained at this USPS source, “the final four digits identify geographic units such as a side of a street between intersections, both sides of a street between intersections, a building, a floor or group of floors in a building, a firm within a building, a span of boxes on a rural route, or a group of Post Office boxes to which a single USPS employee makes delivery.” It can also identify an individual high-volume receiver of mail."

In Bend ZIP+4 numbers for Zip Code 97703 appear to run from1001 to 3999.
This was discovered by trial and error bracket search.
That is about 3,000 ZIP+4 numbers for only the 97703 segment of Bend, Oregon.
What is the range of 97701 and 97702 for Bend?
It appears that that each of the 3 Bend Zip Codes have about 4,000 Zip+4 addresses. Each Zip Code with a ZIP+4 address give about 3 pages of google hits. Excluding the unrelated coincidental hits there are a few hits per each search that return different addresses for the same ZIP+4
Exactly what is the size of a geographical area related to a ZIP+4 address?
The size of a "Sector"?
The size of a "Segment"? Segment can be a floor in a multi story building.
This is an extremely interesting CDC link that cross references ZIP+4 information at the county level to
