UK VAT number - mandatory or not


I am disturbing you guys with a simple question. My account was validated with success, I’ve started selling, but I’ve received an email from amazon in which they are telling me that I need to register in 90 days a UK VAT number in order to be able to keep selling.
So my question, this is mandatory, or, like a friend of a friend:) told me, there is a way to select in seller central that I would like to pay taxes in my country?
Please be so kind and guide me!
Thank you in advance!


If you are storing stock in the UK, then you MUST be registered for VAT before you store the stock.
If you are selling from your own country, then you see up to the distance selling regulations before registering.
So if your using FBA, yes, you must register.
