In 2026, the traditional paper customs form is becoming a rarity. Most major countries, including the US, Canada, the UK, and India, have digitized their entry processes. For travelers entering the US, you will likely use an APC (Automated Passport Control) kiosk or the Mobile Passport Control (MPC) app rather than a blue paper form. India officially transitioned to the "Baggage Rules 2026" digital declaration system in February 2026, meaning flyers are now encouraged to declare items via an app or online portal before they land. While some smaller or less-developed destinations still use paper forms, most "legacy" airlines have stopped stocking them on board to save on paper and weight. If a form is required, it is now more common to find it at a desk in the arrival hall just before the customs line rather than having it handed to you by a flight attendant mid-flight.
