A pre-flight checklist for entering China
Everything you will be asked for, in the order they ask it.
One passport gets you into seven different systems, and each one wants your details in a different shape — the name in a different order, the number without spaces, the card in a format that only works with a local phone number. Check each one here, then copy the values straight into the app.
Nothing is uploaded. The check happens on this page.
