the United Kingdom: phone, postcode, the National Insurance number, the NHS number and the VAT registration number. The VAT number keeps its GB prefix after the country's departure from the European system, so it is a pattern of its own rather than a case of eu-vat. Country groups are meant to be used one at a time: a postal code is five digits in several of them, so two in one detector fight for the same span.
