Numeric Post Formula 
 Determine the numeric post from the first four letters of taxpayer’s last name. The numeric post is calculated by 
 numbering the alphabet from 1 - 26 beginning with the letter A as 01, B as 02, and so on. 
 Numeric post examples and special rules:  
      For a last name Joneket = JONE = the numeric post is 10151405
      For a last name that is less than four characters, fill each ending space with 00. 
           Last name of Coe = COE = the numeric post is 03150500
      For a last name containing an apostrophe or hyphen, omit the punctuation.
           Last name of O’Connor = OCON = the numeric post is 15031514 
      For a last name containing a space, omit the space.  
           Last name of De Von  = DEVO = the numeric post is 04052215

Numeric Post Check Digit Formula
 EXAMPLE: Numeric post = 1 0 1 5 1 4 0 5
 •  Multiply the left most digit by 9, the next digit by 8 and so on, until all digits have a total.
               1     0  1           5      1     4       0         5  
         X 9         8  7           6      5     4       3         2
    =      9         0  7          30      5 16          0         10
 •  Add the totals together. 9 + 0 + 7 + 30 + 5 + 16 + 0 + 10 = 77
 •  Divide the sum by 11. If the remainder is 0 or 1, the remainder is the check digit. If the remainder is greater than 1, 
    subtract the remainder from 11 to obtain the check digit. 77 divided by 11 = 7 with a remainder of 0. 0 is the check 
    digit.

   SSN Check Digit Formula
   Obtain the SSN Check Digit in four steps. 
   EXAMPLE: SSN = 0 0 0 3 4 7 6 3 1
   Step 1: Beginning at the left most digit, multiply each digit of the SSN alternating by 2 and then 1 and format the result 
   as a two-digit number.
                          0        0   0     3          4   7         6           3     1
                  X    2           1   2     1          2   1         2           1     2
               =       00          00  00    03         08  07     12           03    02
   Step 2: Add each digit of the two-digit result from Step 1 to obtain a one-digit number. For the example, the total of the 
   two-digit number 12 is 3 (1+2). 
   Step 3: Add each of the Step 2 results to obtain a total, then determine the unit (ones) position of the total. 
                 0 + 0 + 0 + 3 + 8 + 7 + 3 + 3 + 2 = 26. The unit position of 26 is 6.
   Step 4: If the result of Step 3 is zero, then zero is the check digit. Otherwise, subtract the result of Step 3 from 10. The 
   result is the check digit. For the example,  10 - 6 = 4.  4 is the check digit. 
   Form Code/Liability Period Check Digit Formula
   **This is an example only. Calculate your check digit with the form code and liability period.
   EXAMPLE: Form code/Liability Period = 1 0 4 0 8 1 2 2 3
   •           Multiply the left most digit by 10, the next digit by 9, the next by 8 and so on, until all digits have a total.
               1       0           4   0     8          1   2         2           3
               X 10    9           8   7     6          5   4         3           2
               = 10    0           32  0     48         5   8         6           6
   •           Add the totals together. 10 + 0 + 32 + 0 + 48 + 5 + 8 + 6 + 6 = 115
   •           Divide the sum by 11. If the remainder is 0 or 1, the remainder is the check digit. If the remainder is greater than 1, 
               subtract the remainder from 11 to obtain the check digit. 115 divided by 11 = 10 with a remainder of 5. 11 - 5 = 6. 6 
               is the check digit.
