In 2026, the documents required at check-in depend on your location. For international stays, you are legally required to present a valid passport; many countries also require the hotel to take a scan or photocopy of your visa or entry stamp for local law enforcement. For domestic stays, a government-issued photo ID (like a REAL ID driver's license) is the standard. Regardless of location, most hotels require the physical credit card used for the booking to authorize a hold for "incidentals" (security deposit), which typically ranges from $50 to $200 per night. In 2026, digital IDs and "mobile check-in" are increasingly common, but having your physical documents is essential as a backup. If you are staying on a corporate rate or a "resident" discount, the hotel may also ask for your corporate ID or proof of local residency.
