Business::BR::IE - Perl module to test for correct IE numbers

use Business::BR::IE qw(test_ie canon_ie format_ie random_ie); test_ie('sp', '110.042.490.114') # 1 test_ie('pr', '123.45678-50') # 1 test_ie('ac', '01.004.823/001-12') # 1 test_ie('al', '24.000.004-8') # 1 test_ie('am', '04.117.161-6') # 1 test_ie('ba', '123456-63') # 1 test_ie('ma', '12.000.038-5') # 1 test_ie('mg', '062.307.904/0081') #1 test_ie('rr', '24.006.628-1') # 1 test_ie('ap', '03.012.345-9') # 1

YET TO COME. Handles IE for the states of Acre (AC), Alagoas (AL), Amapá (AP), Amazonas (AM), Bahia (BA), Maranhão (MA), Minas Gerais (MG), Paraná (PR), Rondônia (RO), Roraima (RR) and Sao Paulo (SP) by now.

`test_ie`

is exported by default. `canon_ie`

, `format_ie`

, `random_ie`

and `parse_ie`

can be exported on demand.

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

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)

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)

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)

The state of Bahia uses:

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

The state of Maranhão 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 Maranhão),

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)

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.)

The state of Paraná uses:

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

The state of Rondônia 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

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)

The state of São Paulo uses:

- 12-digits number
- the 9th and 12nd are check digits
- the usual formatting is like
`'110.042.490.114'`

- This documentation is faulty
- If you want handling more than AC, AL, AM, MA, MG, PR, RO, RO and SP, you'll have to wait for the next releases
- The handling of IE-SP does not include yet the special rule for testing correctness of registrations of rural producers.
- the case of unfair digits must be handled satisfactorily (in this and other Business::BR::Ids modules)

Please reports bugs via CPAN RT, http://rt.cpan.org/NoAuth/Bugs.html?Dist=Business-BR-Ids By doing so, the author will receive your reports and patches, as well as the problem and solutions will be documented.
