Description |
Simple check of valid UK VAT Registration numbers. The standard format for UK VAT number must be 9 characters long or 12 characters if a branch trader. The GB prefix has been included as optional, but technically you should include it. The UK VAT format also includes Government Departments and Health Authorities, but I have excluded them for the moment.
