It will show the +4 routes which can be heads up digitized. There are several companies that will sell you very accurate zip code data, Maponics being the one that I use. The five digit zip codes from them are pretty accurate. They do not offer zip+4 boundaries but they do have centroids for the +4 routes.
ZIP codes represent groups of addresses or delivery routes. The +4 codes might narrow it down to a block, a building or single organization. ZIP+4 data is available directly from the USPS (including a file that relates it TIGER) or from third parties who have taken the USPS data and repackaged presumably with value added. The USPS data does not ...
The +4 code is a vital part of the 11-digit DPBC (delivery point barcode), which is comprised of the 5-digit ZIP code, concatenated with the Plus-4 code, concatenated with a 2-digit delivery point, then a check digit.
A five-digit ZIP code covers an arbitrary collection of delivery points (addresses). The USPS is the sole determiner of what ZIP code is assigned to what address, so they are the best source of current and correct data, which changes monthly. Cheap sources of current data are vendors like Semaphore Corporation.
If an address is deliverable, a ZIP+4 is assigned as opposed to just a 5 digit ZIP. Some of the licensees of the data match the street and address range from the USPS with an external street centerline file to provide a geographic point representing a ZIP+4. This level of detail can be generalized back to the ZIP code and derive a ZIP point.
ZIP+4 codes are really linear features (describing a route or portion of a delivery route) and point features (describing an address, a post office, or a post office box). There is no easy mapping between them, even in a many-to-many. Best yet, both periodically change. Good luck. –
I am searching for an address locator for ArcGIS or a (free?) batch service that will output 9-digit zip (Zip+4) from address. I have already geocoded these addresses so I have lat/long from street or point address for a good portion. I do have Esri Street Map Premium service and that allows for 9 digit zip to Lat/long but not Address to Zip+4 ...
As mentioned earlier, there are a few ZIP Codes that deliver across state lines, and there are a few ZIP/sectors that cross county lines. There are 153 ZIP Codes in more than one state. There are 9,000 ZIP Codes in more than one county. There were 11,331 (out of the total 857,400) ZIP/sectors that were split by county.
I have a list of addresses for which I need to get the ZIP+4. I am trying to geocode following https ...
Some community reported benefits to P-Codes: Every location on earth can have a mailing address The encoding of 10 characters plus “+” character is much more efficient in terms of number of bytes than latitude and longitude, which to represent the same level of specificity would need to consist of two floating point
