You Cannot Just Walk Up and Buy a Ticket
This is the detail that trips up more visitors than anything else about the Forbidden City: there is no meaningful walk-up ticket window anymore. Entry is capped at a daily visitor limit and tickets are sold online, tied to your exact passport details, for a specific date. During peak travel periods — national holidays, summer, and any weekend in spring or autumn — tickets can sell out several days in advance. If you're building a Beijing itinerary around 'we'll figure out the Forbidden City when we get there,' you are taking a real risk of simply not getting in.
The official booking channel is the Palace Museum's own site and WeChat mini-program, which is often difficult for foreign visitors without a Chinese phone number or ID, which is the practical reason most international travelers book through a tour operator or ticketing service that handles the passport-based reservation on their behalf. If you do book directly, you will need every visitor's passport number entered correctly — a mismatched passport at the gate is a hard stop, not a formality.
