Ever addressed a card, sealed it, and then realised there is no stamp in the house? From 8 October 2026, you can fix that on your phone. SingPost has started a public trial of digital stamps, which it calls Asia's first, and they work with the letterbox slot downstairs.
> Quick view: buy postage in the SingPost app, write the code on the envelope, post it anywhere. Same price as normal stamps ($0.62 / $0.90). Trial deal: 5 Regular stamps for $1 and 5 Large for $1.50, one set each, to 6 April 2027.
How it works
- Buy in the app. Open the SingPost mobile app (you need a registered account) and buy digital stamps. The minimum is five stamps per denomination.
- Copy the code. Each purchase generates a unique code.
- Write it on the envelope. Put the code on the top-right corner, where a physical stamp would normally go. No printing, no stickers.
- Post it. Drop the letter into any posting box, a post office, or the Return Mail slot at your block's letterbox nest.
That last option is the useful bit. SingPost finished rolling out SingPost@MyBlock in September 2026 across more than 20,000 buildings, so many residents can now post letters and small parcels through the "Return Mail" slot in their existing letterbox nest, where one is available. Pair it with a digital stamp and you never have to leave the block.
What it costs
| Stamp | Normal price | Trial set (one per customer) |
|---|---|---|
| Standard Regular mail | $0.62 each (5 = $3.10) | 5 for $1.00 |
| Standard Large mail | $0.90 each (5 = $4.50) | 5 for $1.50 |
Buy both trial sets and you get 10 stamps for $2.50, saving $5.10 against the normal price.
Fine print worth knowing
- Local mail only. The stamps cover basic mail delivered within Singapore: letters, postcards and printed paper items in a paper envelope.
- Validity differs. Normally priced digital stamps last 24 months from purchase. The $1 and $1.50 promo stamps expire on 6 April 2027, so use them before then.
- One promo set per denomination per customer, and only for registered app users.
- No refunds or cancellations. Digital stamps are non-refundable and non-cancellable.
- It is still a trial. SingPost says this phase is for fine-tuning its scanning of handwritten codes and its sorting workflows, and it is collecting feedback through a survey in the app. Write the code neatly and clearly.
Bonus: collectable designs
The app keeps the look of a real stamp. Standard Regular stamps currently carry the 61st National Day design and Standard Large stamps a World Post Day otter design. Every 15th purchase unlocks a special design, currently the Fullerton Building, home of Singapore's first General Post Office. SingPost says the designs will change with festive and national occasions.
Free roadshow this weekend
SingPost is running a free public roadshow at the atrium of SingPost Centre (Paya Lebar) from 8 to 11 October 2026, explaining how digital stamps work and what else is new in the postal service.
What it means for you
If you send the occasional card, red packet thank-you note, form or cheque by post, this saves a trip to the post office or a hunt for a vending machine. The $1 trial set is the clear win: five letters posted for 20 cents each. With Deepavali and the year-end card season coming, it is worth grabbing both promo sets now and using them before April.
