Need to send letters or parcels within Singapore, but not sure where to start? Lucky for you, it’s a pretty straightforward process. Singapore’s national mail carrier can get all of that done—whether it’s regular letters, bulkier parcels, or important mail you’d like to be able to track. You can even expedite your mail if you have a last-minute item to get delivered.
For frequent senders or larger-volume deliveries, there are also plenty of reliable private courier services you can turn to for added flexibility and convenience.
In this guide, we’ll walk you through everything you need to know about Singapore's postal service, from postage costs and delivery timelines to tracking options, packaging requirements, and where to find post boxes. You’ll also find a rundown of alternative courier services if SingPost doesn’t quite fit your needs. And for bulky or oversized items, like furniture, appliances, or multiple packages, Wise Move makes it easy to compare quotes and book trusted, vetted delivery providers in just a few clicks.
For the vast majority of people, posting a letter via Singapore’s national postal service provider is the default mode of postage.

SmartPac tracked mail is delivered directly into your home’s letterbox, typically the one assigned to your unit in your HDB block or condo. These letterboxes are standardised, secure, and weather-protected, designed to fit small packages and mail reliably. In newer developments, smart letterboxes may even send digital notifications when mail is delivered.
For Registered Mail and SpeedPost, delivery is made to your doorstep, and a recipient’s signature is required as proof of delivery. If no one is home, you’ll usually receive a collection notice with instructions on where and when to retrieve your item.
You can also opt to send and receive tracked mail via POPStations or POPDrop kiosks located around Singapore, which allow for more flexible pickup and drop-off times.
SingPost offers a few service options for sending bulky items within Singapore. If your item weighs below 2kg, you can send it as an untracked package. It should not exceed 324mm (length) x 229mm (width) x 65mm (height). SmartPac is also an option if your item falls within the fixed dimensions offered.
For bulkier and heavier items, you can use SingPost’s SpeedPost or other private courier services.
SingPost’s basic Surface Mail or Air Mail services allow you to send smaller parcels below 2kg overseas. For bulkier and heavier items, you can use SingPost’s SpeedPost International or other private courier services.
