Description |
UK VAT Validation
Conforms to format outlined below:
Country code GB followed by either:
standard:
9 digits (block of 3, block of 4, block of 2 – e.g. GB999 9999 73)
branch traders:
12 digits (as for 9 digits, followed by a block of 3 digits)
government departments: the letters GD then 3 digits from 000 to 499 (e.g. GBGD001)
health authorities:
the letters HA then 3 digits from 500 to 999 (e.g. GBHA599)
For the 9-digit scheme, the 2-digit block containing the 8th and 9th digits is always in the range 00 to 96 and is derived from a weighted modulus-97 check number (an identical algorithm is used for the 12-digit scheme, ignoring the extra 3-digit block)
