Can I add or delete my VAT number in my account?

Yes. Upon requesting a SIM card, you have the possibility to add your VAT number in your account. You can also add, edit or delete your VAT number via My Viking. Beware: if you link a VAT number to your account, it will be linked to all your subscriptions. In other words, it's not possible to link your VAT number to one single telephone number if you have multiple.
