This does not necessarily include travel, but it is somewhat similar to other questions that I thought I would try.
My best friend is trying to buy something through an online retailer in Brazil to deliver to a resident of Brazil. In the buying steps (via Google Website Translate) she asked for a CPF (equivalent to an SSN or NIN).
We tried to call the company (they understandably do not speak English and their Portuguese is very limited). Can anyone explain why a florist needs it and what is right for someone who obviously does not have one to fill the field? (Leaving the field blank will cause a form validation error.)
If there is definitely a better stack for it, please let me know, but this was the next one I could come up with.
