I live and work in the UK but I’m a non-UK national. During the sign-up process I’m asked to provide my national identification number for EU tax reporting purposes.
I understand that this is a requirement but I don’t feel entirely comfortable sharing this number. I’m probably just overly paranoid, but is there any way that I can be assured that this information is handled appropriately? I was always told that the personal ID number was one particularly important piece of personal information in my home country, and since I’ve never had to share it with any other service I’ve used it feels a little intrusive.
