Do I Need a Singapore Arrival Card for Transit at Changi? (2026)

The short answer for transit passengers

No — if you stay airside. ICA exempts travelers who transit or transfer through Singapore without seeking immigration clearance. If you land at Changi, stay in the transit area, and board your onward flight, you never submit the SG Arrival Card (SGAC).

Yes — the moment you leave. Clearing immigration, for any length of time, means entering Singapore, and the card is required for entry. The form is free at ica.gov.sg or on the MyICA app. We are an independent filing service that submits it for $19 for travelers who prefer that; ICA does not endorse services like ours.

What airside means, and why it decides everything

Airside is the passenger area behind immigration and security. Transit shops, lounges, gates, and the famous attractions sit there. Landside is the public area, open to everyone, including people who are not flying. The SGAC question is simply: which side of that line do you stay on?

In practice you stay airside when your bags are checked through to your final destination and you hold a boarding pass for the onward flight. You follow the transfer signs instead of the arrivals signs. If you must collect bags and check in again, ask your airline whether that is possible airside; some transfers force you through immigration, and from that point you are an arriving visitor.

The exemption has no time limit tied to how long you wait. A two-hour connection and a ten-hour overnight stay in the transit area are the same case: no clearance, no card.

Leaving Changi during your layover

Many travelers with a long layover want to see the city, eat real hawker food, or sleep in a proper bed. All of that is welcome — you simply become an arriving visitor. You clear immigration, and from that moment the standard entry rules apply: an SGAC filed within 3 days including the day you land, plus a visa or visa-free entry depending on your nationality. The card is not a visa; the two requirements stack.

File before you fly, not at the counter. If there is any chance you will leave the airport during the connection, submit the card while the decision is still yours to make — the window includes your landing day, and the acknowledgment will already be on your phone when the mood strikes in the transit hall.

Leaving and re-entering takes time. You pass immigration out, then security and immigration back in, so keep a comfortable buffer before your onward flight.

The free Changi tour: the nuance

Changi runs free guided tours of Singapore for eligible transit passengers — a genuinely good deal, with registration booths in the transit area and eligibility built around layovers of at least 5.5 hours and under 24 hours. Details and schedules live on changiairport.com.

Here is the part most guides skip: the tour is not an airside activity. The group clears arrival immigration together, tours the city, and returns through the checkpoint. Changi's own page notes that passengers may enter and exit Singapore immigration only once during a layover, which is why you cannot combine the tour with a separate city trip.

Since joining the tour means seeking immigration clearance, ICA's transit exemption stops applying — the standard entry requirements, including the SGAC with its health declaration, are part of what entering Singapore means. Confirm the current requirements at registration, because tour logistics change; the safest posture is to arrive with a card on file.

Jewel is landside: the common trap

Jewel, the domed attraction with the indoor waterfall, is not in the transit area. Jewel's own FAQ states it plainly: Jewel sits on the landside and is open to everyone, including local residents who are not flying at all. It connects to the terminal arrival halls by walkways, on the public side.

That geography decides your paperwork. A transit passenger who wants to see the waterfall must clear immigration first, and clearing immigration means an SGAC plus your nationality's entry requirements. The airside attractions of the terminals — gardens, lounges, and the rest — need no card at all.

So the quick test for any layover plan: will you cross the immigration line? No line, no card. Any crossing, card.

Decide before you land

The worst version of this problem is deciding at the transfer counter with a dead phone and no filing. The best version costs you five minutes at home: if your layover is long enough that leaving the airport is even possible, submit the card before departure. An unused record is simply never matched to an entry, so over-preparing carries no penalty worth worrying about.

The card is free on the official e-Service, and we file it for $19 if you would rather not deal with the portal — acknowledgment within 24 hours, full refund if we fail to deliver.
