DESCRIPTION

YET TO COME. Handles IE for the states of Acre (AC), Alagoas (AL), Amapa (AP), Amazonas (AM), Bahia (BA), Maranha~o (MA), Minas Gerais (MG), Parana (PR), Rondonia (RO), Roraima (RR) and Sao Paulo (SP) by now.

EXPORT

"test_ie" is exported by default. "canon_ie", "format_ie", "random_ie" and "parse_ie" can be exported on demand.

DETAILS

Each state has its own rules for IE numbers. In this section, we gloss over each one of these

AC

The state of Acre uses:

• 13-digits number
• the last two are check digits
• the usual formatting is like '01.004.823/001-12'
• if the IE-AC number is decomposed into digits like this

    a_1 a_2 a_3 a_4 a_5 a_6 a_7 a_8 a_9 a_10 a_11 d_1 d_2
  

  it is correct if

    a_1 a_2 = 0 1
  

  (that is, it always begin with ``01'') and if it satisfies the check equations:

    4 a_1 + 3 a_2 + 2 a_3 + 9 a_4  + 8 a_5  + 7 a_6 + 6 a_7 +
                    5 a_8 + 4 a_9 + 3 a_10 + 2 a_11 +   d_1   = 0 (mod 11) or
                                                              = 1 (mod 11) (if d_1 = 0)
    5 a_1 + 4 a_2 + 3 a_3 + 2 a_4  + 9 a_5  + 8 a_6 + 7 a_7 +
            6 a_8 + 5 a_9 + 4 a_10 + 3 a_11 + 2 d_1 +   d_2  = 0 (mod 11) or
                                                             = 1 (mod 11) (if d_2 = 0)
  

AL

The state of Alagoas uses:

• 9-digits number
• the last one is a check digit
• the usual formatting is like '24.000.004-8'
• if the IE-AL number is decomposed into digits like this

    a_1 a_2 a_3 a_4 a_5 a_6 a_7 a_8 d_1
  

  it is correct if it always begin with ``24'' (the code for the state of Alagoas),

    a_1 a_2 = 2 4
  

  if the following digit identifies a valid company type

    0 - "normal"
    1 - "normal"
    3 - "produtor rural"
    5 - "substituta"
    6 - "empresa pequeno porte"
    7 - "micro empresa ambulante"
    8 - "micro empresa"
    9 - "especial"
  

  and if it satisfies the check equation:

    ( 9 a_1 + 2 a_2 + 3 a_3 + 4 a_4 + 5 a_5
                      6 a_6 + 7 a_7 + 8 a_8 ) * 10 - d_1 = 0  (mod 11) or
                                                         = 10 (mod 11) (if d_1 = 0)
  

AM

The state of Amazonas uses:

• 9-digits number
• the last one is a check digit
• the usual formatting is like '11.111.111-0'
• if the IE-AM number is decomposed into digits like this

    a_1 a_2 a_3 a_4 a_5 a_6 a_7 a_8 d_1
  

  it is correct if it satisfies the check equation:

    9 a_1 + 8 a_2 + 7 a_3 + 6 a_4 + 5 a_5
                      4 a_6 + 3 a_7 + 2 a_8   + d_1 = 0  (mod 11) or
                                                    = 1  (mod 11) (if d_1 = 0)
  

BA

The state of Bahia uses:

• 8-digits number
• the last two are check digits
• the usual formatting is like '123456-63'

MA

The state of Maranha~o uses:

• 9-digits number
• the 9th is a check digit
• the usual formatting is like '12.000.038-5'
• if the IE-MA number is decomposed into digits like this

    a_1 a_2 a_3 a_4 a_5 a_6 a_7 a_8 d_1
  

  it is correct if it always begin with ``12'' (the code for the state of Maranha~o),

    a_1 a_2 = 1 2
  

  and if it satisfies the check equation:

    ( 9 a_1 + 8 a_2 + 7 a_3 + 6 a_4 + 5 a_5
                      4 a_6 + 3 a_7 + 2 a_8 ) - d_1 = 0  (mod 11) or
                                                    = 10 (mod 11) (if d_1 = 0)
  

MG

The state of Minas Gerais uses:

• 13-digits number
• the 11th and 12th are check digits
• the usual formatting is like '062.307.904/0081'
• to determine if IE/MG number is correct, the computation rules in

    http://www.sintegra.gov.br/Cad_Estados/cad_MG.html
  
  

  must be followed. (Yes, they are boring and hard to describe.)

PR

The state of Parana uses:

• 10-digits number
• the 9th and 10th are check digits
• the usual formatting is like '123.45678-50'

RO

The state of Rondonia uses:

• 14-digits number
• the 14th is a check digit
• the usual formatting is like '0000000062521-3'
• if the IE-RO number is decomposed into digits like this

    a_1 a_2 a_3 a_4 a_5 a_6 a_7 a_8 a_9 a_10 a_11 a_12 a_13 d_1
  

  it is correct if it satisfies the check equation:

    ( 6 a_1 + 5 a_2 + 4 a_3 + 3 a_4 + 2 a_5 +
      9 a_6 + 8 a_7 + 7 a_8 + 6 a_9 + 5 a_10 +
      4 a_11 + 3 a_12 + 2 a_13 + d_1            = 0  (mod 11) or
                                                = 1  (mod 11) if d_1 = 0
  

RR

The state of Roraima uses:

• 9-digits number
• the 9th is a check digit
• the usual formatting is like '24.006.628-1'
• if the IE-RR number is decomposed into digits like this

    a_1 a_2 a_3 a_4 a_5 a_6 a_7 a_8 d_1
  

  it is correct if it always begin with ``24'' (the code for the state of Roraima),

    a_1 a_2 = 2 4
  

  and if it satisfies the check equation:

    ( 1 a_1 + 2 a_2 + 3 a_3 + 4 a_4 + 5 a_5
                      6 a_6 + 7 a_7 + 8 a_8 ) - d_1 = 0  (mod 9)
  

SP
