VatNumber

A VAT registration number, with its country's code at the front: GB980780684.

Use it for a business's VAT number on invoices. For a taxpayer's number other than VAT, use TaxId.

Shape

Its parts keep these rules, and a value that breaks one fails with the rule's name:

• number_of_country: number is in the form of its country's numbers

Example

VatNumber { country: Country.gb number: "980780684" }

text.parse(raw, as: VatNumber) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as GB802311781, DE143454215 or FR84323140391.

Good to know

• Greek numbers start EL, not GR, as the EU's VIES service writes them.
• It checks each country's form and check digit, but it doesn't ask a tax office whether the number is registered.
• == tells you whether two are the same. < and list.sort_by don't take it, so sort by one of its parts instead.

In JSON

A string, in a request, a response or json.write:

"GB980780684""DE143454214""FR59542051180"
