Does a crypto voucher ask for an ID?

I'm curious to know, does the process of acquiring a cryptocurrency voucher typically require the submission of personal identification? Is it standard procedure for crypto voucher providers to verify the identity of their customers, or can one purchase these vouchers anonymously? It's important to understand the privacy implications of using such a service, and whether or not there are any legal requirements in place that mandate the collection of ID information. Can you clarify the specifics of this process for me?
