ABN 1.0.0

Validate Australian Business Numbers.

This package validates Australian Business Numbers (ABNs) and converts Australian Company Numbers (ACNs) or Australian Registered Body Numbers (ARBNs) to ABNs.

The following example show checking of a valid and an invalid ABN:

>>> import abn
>>> abn.validate('53004085616')
'53 004 085 616'

>>> abn.validate('99999999999')
False

To calculate the ABN based on an existing ACN or ARBN:

>>> abn.acn_to_abn('004085616')
'53 004 085 616'

To run the tests or your current Python:

$ python setup.py test

To run the tests over all supported Python versions, install Tox and run:

$ tox
