Safe to add Passport ID to reserve a rental car Online from Europcar?

Very safe to add passport number. Not much anyone can do with your passport number.

It's safe, that number has never had any value.

With an American name and matching passport number, and about $4, you can get coffee at Starbucks.

Mr. E. You obviously haven’t been to Starbucks lately you’ve got to have at least five dollars.😂

Thanks everybody, for your very helpful (and humorous responses :)

I can know check that question off my "To Do" list.

With much appreciation fellow travelers!

regarding using (and leaving) your drivers license as ID instead of your passport have a look at both side by side. Passport - name and number and nationality. DL - name, current address, number, some have height and eye colour and a much better photo and more current.

Which is more dangerous to lose? Both can be replaced, albeit with a degree of hassle, but if a criminal has your current address and the fact that you aren't at home it makes your house much more vulnerable.

True Nigel. How many people realize the US is fairly unique in the total absense of a required national (or even state) identification document. Here the locals are required to have 3.

Thanks for the additional insights, Nigel. Spot on!
