I have a spatial file of the congressional districts of the US, however, the states are numbered in an unknown form. I have searched through all the other files but have found no key or description of the numbering of the states. Am I missing something? Here is the link where I downloaded the files.enter link description here

    You are going to have to be clearer herer. We cannot smell what an unknown form is. Please edit your question. – user4293 Feb 14 '19 at 12:08
  • I'm new to tableau and have only taken a beginner's course on it. So I've never heard of fips code. So I'll look into it, thanks – Kyle Flashman Feb 15 '19 at 4:10

    @philshem This question seems on-topic for both open data and GIS.se. No need to migrate it since it's already here. – csk Feb 15 '19 at 21:55

    considering how many they offload here, i'm all for sending them back – albert Feb 16 '19 at 5:15

Based on comments, it seems your data is labeled with two-digit FIPS state codes. (FIPS stands for Federal Information Processing Standard.)

Here you can download a table with state names and FIPS codes, in this format:

FIPS State Code | Official United States Postal Service (USPS) Code | Name | Geographic Names Information System Identifier (GNISID)

For example:


You can join this table to the shapefile based on the FIPS code in your GIS software. A "join" or "table join" is a standard GIS process, it should be explained in the manual for your GIS software, as well as in many online tutorials. If you have any trouble, head over to GIS Stack Exchange.

Note: US localities have 5-digit FIPS codes. https://en.wikipedia.org/wiki/FIPS_county_code
