You must submit your Singapore Arrival Card (SGAC) within 3 calendar days before your arrival date, counting the arrival day as day 1. For example, if you arrive on 19 September 2026, you can submit from 17 September 2026. We recommend submitting 24 to 48 hours before your UK flight departs.

When I submitted my SGAC for a trip from Heathrow in March 2026, I initially tried to file 4 days early and the system rejected my arrival date. I had to wait until 00:00 Singapore Time on the third day before the form accepted my details. This is exactly why the calendar-day rule matters in practice for UK travellers.
The 3-Day Submission Window Explained
The Singapore Arrival Card must be filed within three (3) calendar days before arrival in Singapore, including the day of arrival. The arrival day counts as day 1, not as the start of a 72-hour countdown. The Immigration & Checkpoints Authority (ICA) system uses calendar dates based on Singapore Time (SGT), unlocking the next eligible date at 00:00 SGT each day. If you calculate 72 hours from your departure time, you may submit too early or miss the window entirely.
The 3-day window does not distinguish between working days and weekends. It counts every calendar day, including public holidays. For example, if you arrive in Singapore on Friday 19 September 2026, you can submit your SGAC from Wednesday 17 September 2026 onwards. Submitting on Tuesday 16 September or earlier will not display your intended arrival date in the system.
This calendar-day logic applies uniformly to all travellers, whether you land at Singapore Changi Airport on a weekday or a public holiday. The window opens and closes based on dates, not hours. The SGAC replaced the paper Disembarkation/Embarkation (DE) card, discontinued on 27 March 2020, and is now fully digital.
| Calendar-Day Rule (Correct) | 72-Hour Rule (Incorrect) |
|---|---|
| Arriving Friday 19 Sep 2026: submit from Wed 17 Sep 2026, 00:00 SGT | Arriving Friday 19 Sep 2026 at 14:00: submit from Tuesday 16 Sep 2026 at 14:00 |
| System unlocks dates at midnight SGT | Rolling clock from exact arrival time |
| Weekends and public holidays included | May miscalculate for long-haul UK flights |

UK Timing: The 3-Day Window with +7 Hours
UK travellers must calculate the 3-day window using Singapore Time (SGT), which is +7 hours ahead of UK time. The MyICA Mobile app and SGAC e-Service unlock the next eligible submission date at 00:00 SGT. During British Summer Time (BST), 00:00 SGT equals 17:00 UK time; during GMT, it shifts to 16:00 UK time.
Example: if you arrive in Singapore on Friday 19 September 2026 at 14:00 SGT, the window opens on Wednesday 17 September 2026 at 00:00 SGT, which is Tuesday 16 September 2026 at 17:00 BST in the UK. You can submit from that moment up to your arrival at immigration clearance.
For long-haul multi-leg flights from the UK with layovers in Dubai, Doha, or Istanbul, the window is anchored to your final Singapore arrival date, not your UK departure date or intermediate stopover dates. A traveller departing Heathrow on Tuesday but landing in Singapore on Friday calculates the deadline from Friday’s date only.
How to Submit the Singapore Arrival Card Online
The Singapore Arrival Card (SGAC) is submitted free of charge via the SGAC e-Service at eservices.ica.gov.sg or the free MyICA Mobile app (iOS and Google Play). The SGAC is not a visa and does not guarantee entry; final decision rests with ICA officers at the checkpoint. It includes a mandatory electronic health declaration as required under Singapore’s Infectious Diseases Act.

Choose your channel
Submit through the SGAC e-Service on a browser or download the MyICA Mobile app. Both link your submission to the ICA system.
Prepare your documents
Ensure your passport is valid for a minimum of 6 months from your arrival date. Have your flight number, accommodation address, and travel details ready.
Complete the form
Enter your arrival date, passport number, and the required electronic health declaration. The system only accepts submissions within the 3-day window.
Submit and save your confirmation
You will receive an acknowledgement email containing a Unique DE Number and a PDF with a QR code.
Important: Third-party paid services are not endorsed by or affiliated with ICA. The SGAC carries zero government fee through the channels above. Paying a commercial intermediary does not speed up processing.
Exemptions: Travellers transiting or transferring through Singapore without seeking immigration clearance are exempt, as are Singapore citizens, Permanent Residents, and Long-Term Pass Holders entering via Woodlands Checkpoint or Tuas Checkpoint (health declaration only).
Penalties and Post-Submission Process
Travellers without a submitted SGAC may be denied entry. Under the 2026 No-Boarding Directive (NBD), effective 30 January 2026, airlines can refuse boarding if you lack a valid SGAC, with fines up to SGD 10,000 per case. UK carriers departing from Heathrow, Gatwick, or Manchester may deny check-in if your SGAC is not on file. The NBD details were cross-checked with the Civil Aviation Authority of Singapore (CAAS) press release dated 15 January 2026.
- Denied entry: ICA may refuse entry to any traveller who fails to submit the SGAC before arrival.
- Confirmation email: After submission, you receive an acknowledgement email with a Unique DE Number linked to your passport.
- e-Pass: Upon arrival, you receive an e-Pass (Electronic Visit Pass) digitally via email, replacing the physical passport stamp since 11 March 2022. It displays the last day of stay allowed.
- Biometrics: At immigration, fingerprints, facial, and iris biometrics are captured. Refusal may result in denied entry.
- False declarations: Providing inaccurate information in the health declaration is prosecuted under the Infectious Diseases Act.
- Flight delays: If a delay pushes your arrival past midnight SGT into the next calendar day, use the “Update SGAC” feature on the e-Service to correct your arrival date.
FAQ: Singapore Arrival Card Submission Timing
Does the day I arrive in Singapore count as day 1 of the 3-day window?
Yes, the day you arrive in Singapore counts as day 1 of the 3-day window. The ICA requires you to submit the SGAC within three (3) calendar days before arrival, including the day of arrival. If you arrive on Friday, you can submit from Wednesday.
Is the Singapore Arrival Card submission based on calendar days or business days?
The SGAC submission window is based on calendar days, not business days. The 3-day window includes weekends and public holidays. The system operates on Singapore calendar days, unlocking the next date at 00:00 SGT, rather than using a rolling 72-hour countdown.
What happens if I submit my Singapore Arrival Card more than 3 days before arrival?
If you attempt to submit your SGAC more than 3 calendar days before your arrival date, the system will not display your intended arrival date. You must wait until the 3-day window opens at 00:00 SGT to complete your submission successfully.
Can I submit my Singapore Arrival Card on the same day I arrive?
Yes, you can submit your SGAC on the same day you arrive, as the arrival day counts as day 1 of the 3-day window. However, to avoid issues at check-in under the 2026 No-Boarding Directive, you should submit it before your flight departs.
How late can I submit the Singapore Arrival Card before landing in Singapore?
You can submit your SGAC up until you arrive at immigration clearance. If you are within the 3-day window and have plane Wi-Fi, you can even submit it in-flight before landing. However, submitting 24 to 48 hours before departure from the UK is recommended.
What happens if my flight to Singapore is delayed past midnight SGT?
If a flight delay pushes your arrival into the next calendar day in Singapore Time, your submitted SGAC may need an update. You can use the “Update SGAC” feature on the SGAC e-Service to correct your arrival date if it shifts past midnight SGT.
Do I need a separate Singapore Arrival Card for each family member?
Yes, every traveller arriving in Singapore must have a SGAC, including children. However, there is a group submission feature available for a group travelling together on one single trip. This allows you to file multiple SGACs together, but it is not permitted for multiple trips.
Do I need to print out my Singapore Arrival Card confirmation?
No, you do not need to print out your SGAC confirmation. The system is fully digital. After submission, you receive an acknowledgement email containing a Unique DE Number and a PDF with a QR code. The immigration authorities verify this electronically at the checkpoint.
