GL (Global Locator) code is Base 32, 2 digits can locate a state, 4 digits can locate a city, 6 digits can locate a street block, 8 digits can locate a house, and 10 digits can locate a person location anywhere in the earth.

GL code uses the format X0Y0X1Y1X2Y2X3Y3, as X0X1X2X3 is the GL Base 32 mapping of the longitude, and Y0Y1Y2Y3 is the GL Base 32 mapping of the latitude.

GL locations starts from the south pole, from the Pacific ocean, hence California starts with 5 (x axis), then the more east you go and the higher the number, e.g., Florida starts with 8, Cairo K, and China, U.

GL uses all the alphanumeric characters except ["I", "L", "O", "P"]

GL code is case insensitive, i.e. it can be in small letters or in capital letters.

GL codes can enable sorting by location, as e.g. locations in most of California starts with 5Q, while Florida locations starts with 8N

The difference between Florida and California is 3 digits and the difference in time zone is 3 hours, which means the difference in GL digits can give indication of roughly how much difference in time zone and distance. One digit different from the left is about 750 miles.
