The paperwork rental counters ask for, and why.
Most international rental counters ask for three things: your valid driver's license, a passport for identification, and a credit card in the renter's name for the deposit. Many also require or strongly recommend an international driving permit alongside your home license, particularly if your license isn't in the local language or alphabet.
Age requirements and young-driver surcharges vary by country and company, so it's worth checking those specifics before booking rather than after. Bringing photocopies of everything as a backup is a small habit that avoids a lot of stress if a document gets misplaced.
