A ZIP code is an internal code for regions served by the US Postal Service. A is for Newfoundland going all the way to Z for parts of British Columbia. tells us that it is in Alberta.Įach subsequent number and letter narrows the area down to a city or town and so on to a street and building. The first letter indicates the province, i.e. Canada uses postal codes similar to this one ( T6X 0Z4). Canada doesn’t have zip codes as the USA does. They are in the format A1A 1A1, which is a six-character string that forms part of a postal address in Canada where A is a letter and 1 is a digit. Join_Count indicates how many join features match each target feature (TARGET_FID).Īnother new field, JOIN_FID, is added to the output when JOIN_ONE_TO_MANY is specified in the Join Operation parameter.What is the ZIP code of Canada List of All States 2021Ĭanadian postal codes are alphanumeric. "Two new fields, Join_Count and TARGET_FID, are always added to the output feature class. Out_feature_class = "C:/data/usa.gdb/states_zips"Īrcpy.SpatialJoin_analysis(target_features, join_features, out_feature_class, "JOIN_ONE_TO_MANY") Target_features = "C:/data/usa.gdb/states" You could possibly do a negative -100m buffer of the zips before the spatial join and see what that does. There will likely be false positives where the zips unintentionally overlap more than one because of border inaccuracies/lack or resolution. You could do a similar thing with zips and cities. In the output feature class, there will be a Join_Count field that will indicate multiple states. With ArcGIS you can use the spatial join tool (or in a script) to find which zip code polygons intersect with more than one state polygons. However, Google Maps is also not authoritative. You should be able to spot check all of these in Google Maps. ST_Intersects(state.geog::geometry, zcta.geog::geometry)ĪND NOT ST_Touches(state.geog::geometry, zcta.geog::geometry)ĪND ST_Area(ST_Intersection(state.geog, zcta.geog)) > (ST_Area(zcta.geog)*0.01) SELECT zcta5ce10, array_agg(state.name ORDER BY state.name) AS states Check out 56168 or even 83832 for a zip code that we're pruning with this added selectivity. If 1% of the ZCTA area isn't in the state, we assume it's a rounding error, or someone fat fingering something at the Census. Note, we qualify states by 1% of the total ZCTA area. Here we query for intersections between TIGER State and TIGER ZCTA datasets. If USPS wanted to a grow up a bit, they'd just convert to the latest ZCTA and provide authoritative GIS polygons. Everyone, including every governmental entity other than USPS, and (the Census for making ZCTA) ignores them entirely. USPS Zip Codes are really horrible and not useful except to approximate. I've updated the code and results with the correct list.Įdit: new state mapping confirmed by the OpenCongress API: Īs a special caveat, ZCTA data isn't USPS Zip Codes. I was using the first, while I should have been using the second, so the state names I listed were wrong. Both are numbers assigned based on the state's alphabetical ordering, but one seems to apply the numbers directly from 1-51 (50 states + DC), while the other skips some numbers.

Print merged.sort().to_string(index=False)Įdit: It seems the Census has two different two-digit codings for states. States = pd.read_csv(census_codes_to_names_url, sep='|') # get number of times each ZCTA appears (most are only 1) # the data often repeats the same (ZCTA, state) pair.

Here's how I generated it (with Pandas in Python): import pandas as pd

Here's the full list with states: 02861 Massachusetts So your example of 42223 does span a state border, but it looks like it is actually between Maryland and Virginia. There are 13 multi-state US Census' ZIP Code Tabulation Areas (ZCTAs): 02861, 42223, 59221, 63673, 71749, 73949, 81137, 84536, 86044, 86515, 88063, 89439 & 97635.Īs others have mentioned, there are a few different ways to figure out the area covered by a ZIP Code, but ZCTAs are the easiest, and the only official version that I know of.
