Digital Stamp
A Digital Stamp is a digital alternative to the traditional physical stamp. Instead of purchasing a stamp at a post office, POPDrop kiosk or Self-Service Kiosk, you buy postage directly through the SingPost mobile app and receive a unique code. Simply write that code on your envelope in place of a stamp — no label, no sticker, nothing to peel or stick.
Digital Stamps let you buy postage anytime, anywhere — no post office visit needed, no queuing, and no need to keep physical stamps on hand. As long as you have the SingPost app, you're ready to post.
Digital Stamps are available exclusively through the SingPost mobile app. You will need to be logged in to your SingPost account to purchase. If you don't have one, registration takes just a few minutes directly on the app.

Any posting box, post office, or SingPost@MyBlock slot — the same as you would with any other mail.

No printing needed. Write the unique code generated in your app clearly in the top-right corner of your envelope, where a stamp would normally go, using a dark blue or black pen in block letters. Then drop your mail into any posting box, post office, or SingPost@MyBlock slot, just as you normally would.
Yes. Use a dark blue or black pen or marker, and write in clear block letters. This ensures our sorting facility can read the code accurately and process your mail without delays.

Yes. Digital Stamps require a minimum purchase of five per denomination per checkout. Any unused codes are stored in your app transaction history and remain available until you are ready to use them.

Your past Digital Stamp orders are listed on the Digital Stamp homepage in the app. Tap any order to view its details.
First, check your transaction history under the Digital Stamp section of the app to see if the code is listed there. If it is not, please contact our customer service team for assistance.
Cross out the error clearly and rewrite the correct code beside it, or start with a fresh envelope. If our processing team cannot read or validate the code, the mail may be treated as unpaid and returned to the sender, or subject to additional postage charges.
