Geocode Files are exports of data records that contain locational information from the PC*MILER database – such as city names, place names, ZIP/Postal Codes, Standard Point Location Codes (SPLC), and latitude/longitude coordinates. These files are provided by ALK strictly for use in conjunction with the corresponding PC*MILER license purchased.

The available PC*MILER Geocode Files include:

Important Notes

Geocode Files can be opened in Notepad, WordPad or in a spreadsheets program. Due to the size of some files and the speed of the computer you are using, the files may take a few minutes to open. If you receive a message saying that Notepad or WordPad is not responding, we recommend using a different text file utility.

Some files may include Unicode text format and may list characters outside the 0 to 127 ASCII range. Within those files, some place names may include special characters such as Õ, é, and ü. We recommended that such files be opened using UTF-8 or Arial Unicode MS format so that all characters display appropriately. To do so, if you are using Notepad go to File > Open then make an appropriate selection in the Encoding drop down list before opening the file.

In some Geocode Files, you may see a double comma in a record. This indicates that the information for the identified category of data is not available in the database. For example, some files that include ZIP/Postal Codes do not include codes for every location; therefore, the ZIP/PostalCode category will show a double comma.

Files are based on database information included in the version release of PC*MILER. For some products, quarterly releases of ZIP Code data are available. There are no quarterly releases of this data in Geocode File format.

  • For files that include latitude/longitude coordinates, they are included without the decimal point and are interpreted as ddd.dddddd. (i.e. The integer values need to be divided by 1 million to obtain the latitude and longitude in decimal format.)

  • If you are looking for Mexican Postal Code information, please directly contact to purchase your own license for the GeoPC Mexico dataset. ALK does not have a redistribution license with GeoPostcodes that would allow users to work with their postal code data in any context outside of its use within the PC*MILER application.
