If you work for a company that has a VAT number, I assume someone in your company can provide it to you (the company accountant perhaps). If you are an individual and you do not have a VAT number, I assume you would leave that field blank.
You can Google search "VAT number" for more information about what a VAT number is.
Customer support may have a better answer for you (During UK business hours).
