We earn from this. When someone signs up through our link and completes a booking, Klook gives us a US$5 discount of our own. Paid to us so far: US$0.00 from 0 referrals. The box below ranks by what you save, and will often pick something that pays us nothing.
Klook’s card and member offers this month
Klook rarely prints a working card code in the open. It releases most of them on its own pages at set times, in limited numbers, so “On Klook’s page” below means go there when the code is due. Ended offers leave this table by themselves.

From Klook’s Singapore promo list, last updated by Klook on 6 Nov 2026 and read by us on 9 Nov 2026, with links to its DBS, OCBC and UOB pages. Dollar amounts are as Klook’s Singapore pages show them.
Which day to look
Klook runs a weekly pattern, and a card code that drops at noon on Saturday can be gone that afternoon. If your booking can wait a few days, this is worth planning around.
| Day | Klook’s weekly deal | Card codes released |
|---|---|---|
| Monday | Up to 50% off Japan bookings | None listed |
| Tuesday | Up to $80 off China bookings* | DBS Chromo at 12 pm; UOB’s China attractions and Japan codes |
| Wednesday | Up to $10 off with OCBC Visa | OCBC Visa at 12 am |
| Thursday | Up to $55 off attractions, tours and experiences* | Maybank tours and attractions |
| Friday | Up to $70 off hotels* | DCS hotels and transport |
| Saturday | 50% off with DBS/POSB cards | DBS/POSB at 12 pm |
*Klook marks these “stacked with payment discounts”, so the top figure needs a card offer as well. From Klook’s cheatsheet on the same page.
How the referral works, in the order it happens
- You open the link before you have an account. Klook’s help pages only describe a referral through signing up from the link, so don’t create an account some other way first.
- You sign up. Klook’s invite page reads “Get a US$5 discount after you sign up”. It shows US dollars even on Klook’s Singapore site.
- You book. The discount goes on a booking of yours. Klook’s help page says a code tied to your account applies itself on eligible bookings, and you can check it under “Discounts” before paying.
- We get our discount later. Klook says within 24 hours of a completed booking, and also that it may wait until the voucher is redeemed and the activity is done. That’s why our tally above can lag.
What we haven’t confirmed
Nobody new has signed up through this link yet, and you can’t refer yourself, so these stay open until a real new user tries it.
- The minimum spend and expiry on the US$5.
- Whether EF4BUK can be typed in at sign-up, or works only through the link. Use the link to be safe.
- Whether the US$5 works on the same booking as a card code. Klook’s Singapore page talks about stacking bank codes with sale prices, but its help pages don’t set out a rule.
- Whether every code above still has redemptions left when you read this.
Travel blogs advertise their own first-booking codes, some claiming 10% off. We haven’t tried them, so they aren’t in the box above. If one works for you, it would beat US$5 on a larger booking.
Questions
Is there a Klook promo code for first-time users in Singapore?
Yes. A new account opened through a referral link gets US$5 off, and ours is EF4BUK. Klook also lists up to 8% off hotels for people new to its hotels, capped at $10.
I already use Klook. Is there anything for me?
Mostly through a card. Pick yours in the box above. Without one, the steady offer we found is 5% off hotels if you’ve booked one with Klook before.
Why does the table say “On Klook’s page” instead of showing the code?
Those codes change weekly or monthly and are limited in number. Printing last week’s would just send you to a rejection at checkout. Where Klook publishes a fixed code, such as the Automobile Association’s or Grab PayLater’s, it’s in the table.
Is the discount in US or Singapore dollars?
The referral is shown as US$5. The card offers are shown in dollars on Klook’s Singapore pages. The box above converts the US$5 at today’s MAS rate so the two can be compared.
Where this comes from
EF4BUK comes from our own Klook account, and we opened the invite page on Klook’s Singapore site on 9 Nov 2026 to read what a new user sees. The offers come from Klook’s pages, read by hand and dated. None has been tried at checkout yet, so read them as “listed by Klook”. Klook’s own referral help page and promo code help page are the source for how codes apply.
