Singapore – Postal Service

Who runs the postal service in Singapore, and who are the main providers?

Singapore Post Limited, widely known as SingPost, is an associate company of Singtel and Singapore’s appointed Public Postal Licensee, responsible for delivering both domestic and international postal services. As the designated licensee, SingPost holds the authority to operate postal services — encompassing the receipt, collection, and delivery of letters and postcards within Singapore and overseas — through to 31 March 2037.

The Singapore government brought SingPost’s monopoly over basic mail services to an end on 31 March 2007, opening the market to competition from 1 April 2007. Any organisation wishing to provide domestic or international basic mail services in Singapore must first secure a licence from IMDA. In practice, SingPost continues to dominate everyday letter and parcel delivery, though the market remains open — a structure more comparable to the Netherlands (PostNL) or Sweden (PostNord) than to a fully government-controlled postal monopoly such as Australia Post.

Unlike Australia Post or NZ Post, SingPost is not a direct government entity — its principal shareholder is the telecommunications company Singtel. IMDA nonetheless designates SingPost as the Public Postal Licensee, binding it to Universal Service Obligations that require it to provide collection and delivery services for letters to any person in Singapore upon request, and to maintain posting boxes and post offices across the island.

SingPost also delivers logistics services covering domestic and international markets, warehousing and fulfilment, and global delivery solutions, alongside postal, agency, and financial services through its post offices, Self-service Automated Machines (SAMs), and online portal. Singapore currently has 44 post offices, more than 7,000 POPStation lockers, and 269 SAM kiosks.

Private courier operators — including DHL, FedEx, UPS, Ninja Van, and J&T Express — compete vigorously in the parcel delivery space, particularly within the rapidly growing e-commerce segment. SingPost additionally serves as Singapore’s UPU Designated Operator, representing the country in relevant Universal Postal Union forums.

How fast and reliable is postal delivery in Singapore?

As a compact city-state spanning roughly 730 square kilometres, Singapore achieves domestic delivery speeds that rank among the fastest in the region. Standard domestic mail reaches its destination within 2 working days, provided it is posted before 5 pm on Mondays to Thursdays and before 6 pm on Fridays in post boxes located outside the Central Business District (CBD). For post boxes within the CBD, cut-off times are extended to before 7 pm on Monday to Thursday and before 8 pm on Friday.

Standard domestic mail is sent without tracking, but SingPost provides a range of faster and trackable options, accessible through post offices, SAM kiosks, and the vPOST online portal. For those requiring confirmation of receipt, registered mail differs from basic mail by offering proof of delivery and a degree of tracking functionality.

For international mail, delivery timelines vary considerably depending on the destination and the chosen service tier. SingPost’s Speedpost services provide tracked, express international delivery to most key destinations, while economy options rely on the standard postal network and offer less certainty around transit times. The International Registered Service does not provide comprehensive online tracking, and scanning of registered items at every point along the route is not mandatory. For international deliveries, scan events may differ based on the practices of the receiving country’s postal authority, and updates are only visible when the destination postal service provides them.

Mail volumes in Singapore have declined by over 40% since FY2019/2020, driven by the widespread shift to digital communication — a trend that has put pressure on SingPost to reconcile rising operating costs with diminishing postal revenues. Despite this structural strain, domestic delivery performance continues to be broadly dependable across this densely urbanised territory. Always confirm current delivery performance targets directly with SingPost’s website, as service standards are subject to revision.

What additional services are available at post offices in Singapore?

SingPost provides an extensive array of products and services — spanning postal, agency, and financial offerings — through its post offices, SAM kiosks, and online platform. For expats, this transforms a post office visit into a far more versatile errand than a simple parcel drop-off.

Post offices in Singapore routinely offer the following services in addition to standard mail:

• Bill payments: Utility bills, season parking charges, and government-related fees can be settled at post office counters or SAM kiosks.
• Government agency services: Post offices act as agents for a variety of government transactions, including the collection of identity documents, road tax renewals, and CPF-related services.
• Financial services: Select post offices provide basic banking and insurance products.
• GST/customs payment: SingPost delivers dutiable postal parcels once payment has been made through the SingPost mobile app, a SAM kiosk, or at any post office counter.
• Philatelic products: Commemorative stamps and collectors’ editions are stocked at major post offices.
• Packaging supplies: Envelopes, bubble wrap, boxes, and prepaid smartpac mailers are available for purchase in-store.

To broaden customer access and convenience, SingPost has grown its network to approximately 2,500 touchpoints, incorporating additional POPDrops, partnerships with Cheers and FairPrice XPress convenience stores, and collaboration with PICK lockers. This means a wide range of postal services — particularly parcel collection, drop-off, and stamp purchases — can now be accessed at convenience outlets and supermarkets across the island, not solely at dedicated post offices.

The range of services available is broadly consistent across SingPost locations, though flagship branches (such as the SingPost Centre at Paya Lebar) typically offer a more comprehensive selection than smaller neighbourhood outlets. It is worth checking the SingPost branch locator for specific services at your nearest location.

Does the postal service deliver to every address in Singapore, and what happens if it doesn’t?

Singapore is an entirely urbanised nation, meaning there is no distinction between urban and rural addresses. The island has no remote or underserved areas — every location carries a defined street address served by a postal code. This makes Singapore fundamentally different from larger countries where infrequent or limited delivery may affect rural communities.

Under its Universal Service Obligations, SingPost must provide letter collection and delivery services to any person in Singapore who requests them, and sustain a network of posting boxes and post offices throughout the island. In practical terms, this means letterbox delivery reaches essentially every residential address, covering HDB public housing blocks, private apartment complexes, and landed properties alike.

When a parcel cannot be delivered — for instance, because no one is at home — SingPost operates a layered fallback system. SingPost will attempt redelivery within the next few working days; after three unsuccessful attempts, the item is returned to the sender. Recipients can also request that a parcel be left at their doorstep by contacting SingPost’s customer service line on 1605.

For tracked or registered items, the item is held at the designated post office for the following 10 working days. Transfers or redirections to another post office or POPStation are not permitted, though the recipient may authorise another person to collect the item on their behalf.

The extensive network of over 7,000 POPStation lockers offers a practical self-collection alternative, enabling recipients to retrieve parcels at their convenience. POPStation points are located in HDB precincts, MRT stations, shopping centres, and supermarkets, making missed deliveries far less disruptive than in countries where self-collection infrastructure is sparse.

How do you write a postal address in Singapore?

English is one of Singapore’s four official languages, alongside Chinese, Malay, and Tamil. All addresses must be written in English for both domestic and international mail. The format differs from many European countries in that there is no state, province, or region to include — Singapore is a single city-state, so “SINGAPORE” functions simultaneously as both the city and the country.

The standard address format for a residential property in Singapore is structured as follows:

1. Recipient’s full name
2. Block number and street name (e.g. Blk 35 Mandalay Road) — or simply the house number and street name for private properties
3. Floor and unit number, where applicable, in the format #floor–unit (e.g. #13-37), followed by the building name if one exists
4. “SINGAPORE” followed directly by the six-digit postcode on the same line (e.g. SINGAPORE 308215)
5. “REP. OF SINGAPORE” or “SINGAPORE” on the final line when mailing from overseas

A realistic example for an HDB flat address appears as follows:

The floor and apartment number are expressed using the format #13–37 (denoting the 13th floor, unit 37). This is a distinctively Singaporean convention that often surprises newcomers — the hash symbol (#) preceding the floor–unit combination is standard practice across all property types, from HDB blocks to high-end condominiums.

For maximum clarity and legibility, it is advisable to write the entire address in capital letters. Common errors to avoid include omitting the unit number for apartment buildings (which may render mail undeliverable), placing the postcode on a separate line rather than directly after “SINGAPORE”, and using the outdated four-digit postcode format, which was discontinued in 1995.

How do you find or look up a postcode in Singapore?

Singapore transitioned to a six-digit postal code system in 1995, replacing the four-digit format introduced in 1979. Given Singapore’s compact geography and the fact that most buildings constitute singular, dedicated delivery points, the postal code functions as a precise and self-contained identifier for individual buildings — akin to a geocode.

The format is a six-digit numeric code (e.g. 123456), in which the first two digits denote the postal sector and the remaining four digits identify the specific delivery point — that is, the individual building or block. In mapping applications such as Google Maps and Citymapper, entering only the six-digit postal code is usually sufficient to pinpoint the correct building without any additional address details.

To look up a postcode, the most authoritative official tool is the SingPost Postal Code Finder, available on the SingPost website. The Singapore Land Authority (SLA) also operates the OneMap portal, a government-maintained mapping service where addresses can be searched and cross-referenced against their official postcodes.

Postal codes for private residential, commercial, and industrial buildings are allocated based on the alphabetical ordering of street names within each sector — beginning with streets starting with ‘A’, then ‘B’, and so on. Because the postcode itself does not encode a building’s street number, it is essential to use an official lookup tool rather than attempting to estimate a code. Every address in Singapore carries a six-digit postal code, and there are no unpostcoded areas anywhere on the island.

What should expats know about receiving parcels and international mail in Singapore?

Singapore has a clearly structured process for clearing incoming international parcels, and expats are well advised to acquaint themselves with the relevant customs and GST rules before ordering goods from abroad.

GST on imported goods: Goods brought in by air or post — excluding intoxicating liquors and tobacco — may be eligible for import GST relief if the Cost, Insurance, and Freight (CIF) value does not exceed S$400. Where the CIF value exceeds S$400, GST is levied on the full value of the goods. Singapore’s current GST rate is 9% (as of 2024) — always refer to the Singapore Customs website for the prevailing rate and applicable thresholds.

Handling and admin fees: SingPost charges a flat fee of S$10.90 per consignment for acting on the recipient’s behalf in collecting GST or applicable duties payable to Singapore Customs. This handling fee must be paid alongside any GST and/or duty owed, and is non-refundable. Where goods arrive without a commercial invoice attached, SingPost additionally imposes a flat administrative fee of S$10.90, which is also non-refundable.

How notification and payment work: When dutiable items arrive in Singapore, recipients are notified via the SingPost app, email, letter, or SMS, depending on the contact details provided on the parcel’s commercial invoice. Payment must be completed within 14 days of the notification date; failure to act within this period will result in the item being returned to the sender. Once payment is confirmed, delivery typically follows within the next 2–3 working days.

Parcels without a commercial invoice: Where a postal parcel arrives without its commercial invoice attached, SingPost will retain the item and notify the recipient by letter, requesting that invoices and supporting documents be submitted to SingPost. These will then be forwarded to the Immigration and Checkpoints Authority (ICA) for verification before GST and duty are calculated.

Prohibited and restricted items: Singapore enforces strict controls on what may be imported by post. Prohibited items include chewing gum (with limited medical exceptions), certain weapons, drug paraphernalia, and materials deemed objectionable. Restricted items — such as medicines, certain food products, and animals — require permits from the relevant authority prior to importation. Always consult the Singapore Customs controlled goods list before sending or expecting any restricted items.

Changes to US-bound shipments: Following recent amendments to US import regulations that eliminated de minimis exemptions, all commercially valued shipments destined for the US are now subject to duties and taxes from 29 August 2025. If you are sending parcels to the United States, review SingPost’s current guidance carefully, as services and requirements have undergone significant changes.

Are there reliable alternatives to the national postal service in Singapore?

Singapore’s standing as a global logistics hub means that a broad range of private courier and express delivery operators are active in the country, giving expats strong alternatives to SingPost for both domestic and international shipments.

International express couriers: DHL Express, FedEx, and UPS all maintain substantial presences in Singapore. These providers are generally quicker than SingPost’s economy international options, deliver comprehensive door-to-door tracking, and are better suited to high-value goods, time-critical business documents, or shipments destined for countries where SingPost’s standard service may be less consistent. The main trade-off is price — international express couriers cost considerably more than SingPost’s standard international postage rates.

Regional and local couriers: J&T Express held a 25.4% regional parcel market share in 2024, benefiting from significant economies of scale. Ninja Van is another well-established last-mile operator with a strong presence in Singapore, widely used by e-commerce platforms. These providers tend to be price-competitive for domestic deliveries and intra-regional shipments within Southeast Asia.

When to choose a private courier: Private couriers are generally preferable to SingPost when sending high-value or fragile items that require comprehensive insurance coverage, when reliable end-to-end tracking is non-negotiable, for time-sensitive business-critical shipments, or when delivering to countries where the local postal network is unreliable. For ordinary letters, bills, and low-value parcels within Singapore, SingPost remains the most affordable and accessible choice.

SingPost has also broadened its own reach to around 2,500 touchpoints through partnerships with Cheers and FairPrice XPress convenience stores and collaboration with PICK lockers, narrowing some of the accessibility advantage that private operators once held.

Frequently asked questions

How do I redirect my mail after moving within Singapore?

SingPost provides a Mail Redirection service that forwards correspondence from your former address to your new one for a fee. Applications can be submitted online through the SingPost website or in person at any post office. The service is offered for various durations — commonly three, six, or twelve months. It is prudent to arrange redirection before your moving date and to update key correspondents — including banks, government agencies, and employers — directly with your new address, as mail redirection cannot be guaranteed for every mail type.

Will my rental property have a mailbox?

Yes — the vast majority of residential properties in Singapore, whether HDB flats, private condominiums, or landed houses, come with individual letterboxes. HDB blocks feature communal letterbox clusters at ground level, arranged by unit number. Private condominiums typically house letterboxes in the lobby or within a dedicated mailroom. If you are renting, ask your landlord where your letterbox is situated and whether a key is required to access it.

How long do international letters take to arrive in Singapore?

Delivery times for international mail depend on both the service selected and the country of origin. Speedpost Express from major destinations typically arrives within 3–7 working days. Economy international options may take anywhere from 2–6 weeks, and certain standard postal routes — especially those involving countries with less developed postal infrastructure — can take longer still. For up-to-date indicative timelines by country and service level, refer to the Rate Calculator on the SingPost website.

What happens if I miss a parcel delivery?

SingPost will make a further redelivery attempt within the next few working days; after three unsuccessful attempts, the item is returned to the sender. For tracked parcels, the status can be monitored through the SingPost app or website, and a suitable redelivery window can be arranged by calling their customer service line (1605). Many e-commerce deliveries are now directed to POPStation lockers as standard, effectively eliminating the missed-delivery problem altogether.

How do I send valuables or important documents safely in Singapore?

For critical documents or items of moderate value, SingPost’s Registered Mail service provides proof of posting alongside limited tracking capability. For higher-value goods, consider an insured service or a private courier such as DHL or FedEx, which offer comprehensive shipment insurance and detailed end-to-end tracking. Always declare the accurate value on customs documentation for international shipments — under-declaring to reduce duties can result in the item being seized or penalties being imposed.

Is GST always charged on international parcels sent to me in Singapore?

Goods imported by air or post (excluding intoxicating liquors and tobacco) may qualify for import GST relief where the CIF value does not exceed S$400. Where the value surpasses this threshold, GST is applied to the entire value of the goods. Bear in mind that SingPost also levies a S$10.90 handling fee per dutiable consignment (as of 2025). Always verify the current thresholds and rates with Singapore Customs.

Can I use Singapore Post to send parcels internationally from Singapore?

Yes. SingPost offers an array of international parcel services including Speedpost Priority, Standard, and Economy, as well as Speedpost Direct International for select destinations. Note that from 25 August 2025, only letter mail (documents carrying no declared value) may be sent to the United States via standard post; all other items must be dispatched via Speedpost Express through a post office counter. Always consult SingPost’s current country-specific guidance before posting internationally, as regulations are subject to change.

Where can I buy stamps in Singapore?

Stamps are available at SingPost post offices and at SingPost Self-Service Automated Machine (SAM) kiosks located throughout the island. They can also be purchased online via the SingPost website and app. For those who prefer not to visit a post office, SAM kiosks offer a convenient alternative — they accept both cash and card payments and can weigh items to determine the correct postage required.
