ABN

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
