ORA_CO_INDIVIDUAL	Individual for Colombia	14 or less	Numeric characters only	No	No Check Digit Validation		Good: 80421487 80012737942 Bad: 9005240020A3456 (Characters not allowed) 12345678945454567 (Invalid format, too long)
ORA_CO_FOREIGN_ENTITY	Foreign Entity for Colombia	16 or less	Numeric characters only	Yes, last digit	11- Modulo 11 (71*N(1)+67*N(2)+59*N(3)+53*N(4)+47*N(5)+43*N(6)+41*N(7)+37*N(8)+29*N(9)+23*N(10)+19*N(11)+17*N(12)+13*N(13)+7*N(14)+3*N(15) )		Good: 80421487, 80012737942 Bad: 9005240020A3456 (Characters not allowed), 12345678945454567 (Invalid Format - too long)
ORA_CO	Colombia	16 or less	Numeric characters only	Yes, last digit	11- Modulo 11 (71*N(1)+67*N(2)+59*N(3)+53*N(4)+47*N(5)+43*N(6)+41*N(7)+37*N(8)+29*N(9)+23*N(10)+19*N(11)+17*N(12)+13*N(13)+7*N(14)+3*N(15) )
ORA_CO_NIT	Colombia NIT	16 or less	Numeric characters only. Prefix 0 if the number of digits is less than 15.	Yes, last digit	Each number of the NIT is multiplied starting from right to left, with a sequence starting from 3, then 7, then 13, then 17, then 19, then 23, then 29, then 37, then 41, then 43, then 47, then 53, then 59, then 67, and finally 71. So, for the NIT number 890321567, each number is to be multiplied by 41; 37; 29; 23; 19; 17; 13; 7; 3. Then sum all the results.. For the NIT number 890321567: (8*41) + (9*37) + (0*29) + (3*23) + (2*19) + (1*17) + (5*13) + (6*7) + (7*3) = 913. Later the result must be divided by 11 (the Module). For the NIT number 890321567: 913 / 11 = 83 integers and 0 remainders. After the division, if the remainder is equal to 0 or 1, no more actions are required; otherwise, the remaining must be subtracted by 11 (11 - remaining of the division), resulting in the following Validation Digit (VD): If the remainder = 0 then the VD is 0; If the remainder = 1 then the VD is 1; Else the VD = (11 - remainder). In our example, the VD for NIT 890321567 is 0.		Good: 8903215670 900517231-(0*71) +(0*67) + (0*59) + (0*53) + (0*47) + (0*43) + (9*41) + (0*37) + + (0*29) + (5*23) + (1*19) + (7*17) + (2*13) + (3*7) + (1*3) = 672 672 / 11 = 61 integer 1 remainder In this example, the VD for NIT 900517231 is 1. Example A: NIT 900517231 (9*41) + (0*37) + (0*29) + (5*23) + (1*19) + (7*17) + (2*13) + (3*7) + (1*3) =672 672 / 11 = 61 integer 1 remainder In this example, the VD for NIT 900517231 is 1. Example B: NIT 900524002 (0*71) + (0*67) + (0*59) + (0*53) + (0*47) + (0*43) + (9*41) + (0*37) + (0*29) + (5*23) + (2*19) + (4*17) + (0*13) + (0*7) + (2*3) = 596 596 / 11 = 54 integer 2 remainder VD = 11 - 2 = 9 In this example, the VD for NIT 900524002 is 9. Bad: AR1234567 (Invalid format, only numbers are allowed) 412615338 (Invalid check digit)
ORA_CO_NIT:FOREIGN	Foreign Business Unit Entity for Colombia with Foreign Origin	20 or less	No restrictions on characters	No	No Check Digit Validation		Good: AR1234567
