Proposal to add new field for Organisation contacts to record the Tax Identification Number: ABN (AU), VATIN (EU), TIN/EIN/FEIN/IRS EIN/EIN TAX ID (US) and there's probably more variations. This could also be useful on Individual contacts as well.

This information is also very relevant for the CiviCRM Domain, Organisation Contact. The CiviCRM Contribution message templates could do with adding this information to the default template.

Raising as a proposal here to gather thoughts and find out if people are recording this information elsewhere, renaming the SIC Code field for example. Not looking for responses like: "just use a custom field!" and "change the default templates" - because that's what we already do.
