Notes on Non-Zero Number in First Digit of 6-Digit SAME Number

                                               * RE: column 3

If subdivisions are employed, there may be from 2 to 9 of them.

     In the case of the maximum of nine subdivisions, the following assignments
     would be used in the first digit:

                               1 = Northwest 1/9  
                               2 = North Central 1/9  
                               3 = Northeast 1/9
                               4 = West Central 1/9
                               5 = Central 1/9
                               6 = East Central 1/9
                               7 = Southwest 1/9
                               8 = South Central 1/9
                               9 = Southeast 1/9

     For less than 9 subdivisions, the following numbering convention is
     normally used depending on the desired size and/or orientation of the area
     such as from Northwest to Southeast, North to South, West to East, or
     Northeast to Southwest:

                               1 = Northwest 1/3, 1/2, or 2/3 as appropriate
                               2 = North 1/3, 1/2, or 2/3 as appropriate
                               3 = Northeast 1/3, 1/2, or 2/3 as appropriate
                               4 = West 1/3, 1/2, or 2/3 as appropriate
                               5 = Central 1/3 (or as appropriate)
                               6 = East 1/3 or 1/2, or 2/3 as appropriate
                               7 = Southwest 1/3, 1/2, or 2/3 as appropriate
                               8 = South 1/3, 1/2, or 2/3 as appropriate
                               9 = Southeast 1/3, 1/2, or 2/3 as appropriate
