Hi I wondered if any UK developers have had this issue. I tried to buy a licence, but was told by Vuforia that I would need a VAT number. I explained that my UK company, like many in the UK is not VAT registered. Vuforia wouldnt have that. They wanted me to get the client to supply a VAT number - I'm the client, the app is for me. Then I tried to buy a licence as an individual. Once again Vuforia said I needed a VAT number.
Basically as they are merely supplying a computer generated software code with no physical manifestation it seems more that an little stupid.
