Macao Post Tracking

Macao Post tracking follows registered letters, parcels, and EMS express items handled by the Macao Post and Telecommunications Bureau (Correios e Telecomunicações de Macau, CTT), the official postal operator of the Macao Special Administrative Region of China, which was founded on 1 March 1884. Paste your Macao Post tracking number into the tracker on this page to see the latest scans, and use the same 13-character number to follow a shipment from Macao across the destination country's postal network in one place.

Macao Post Tracking Number Format

A Macao Post tracking number is a 13-character code built on the Universal Postal Union (UPU) S10 standard: two letters, nine digits, and the ISO country code MO for Macao (for example, RR123456789MO). The first two letters identify the product, the nine digits are the item's unique serial number, and the final MO confirms the item originated with Macao Post. CTT applies the same format to registered mail, parcels, and EMS, so the tracking number is sometimes called an item ID, a registered number, or an EMS number depending on the service used.

Ordinary unregistered letters and printed matter carry no S10 number and cannot be tracked, so a trackable Macao Post shipment always means a registered, parcel, or EMS item. The order number an online store assigns is not the same as the postal tracking number; the S10 number is the one that begins with two letters and ends in MO.

Where to Find Your Macao Post Tracking Number

The Macao Post tracking number appears in a few predictable places depending on how the item was sent:

• On the receipt issued at the post office counter when a registered, parcel, or EMS item is posted.

• In the shipping or dispatch confirmation email from an online store that ships from Macao.

• On the customs (CN22/CN23) or address label attached to the parcel.

• Inside the Track and Trace section of the Macao Post mobile app for items posted through an account.

For online purchases, the store often shows an order number first and the S10 tracking number only once the parcel is handed to Macao Post. If only an order number is visible, wait for the dispatch email, since the postal tracking number is the two-letter code ending in MO, not the retailer's order reference.

Macao Post Tracking Number Example

Every trackable Macao Post number uses the same S10 shape, and the two-letter prefix indicates the product. The table below lists the prefixes CTT documents for its tracked services.

The RR, EE, and CP prefixes are the ones Macao Post publishes as examples for its Track and Trace tool. Other two-letter combinations can appear for specific registered products, so the two-letter prefix indicates the broad product family while the MO suffix is the dependable sign that Macao Post is the origin.

Macao Post Tracking Status Guide

Macao Post tracking moves an item through a sequence of scans from counter acceptance to final delivery, and EMS and registered items generate the most complete scan history. The table below explains the statuses commonly seen on a Macao Post shipment.

Why Macao Post Tracking Is Not Updating or Not Working

Macao Post tracking that has not updated for several days is usually still in transit rather than lost, because scans are recorded at handover points and not continuously. The reasons below explain the most common gaps.

Awaiting the first scan. A newly created label can show "no information" until the item is physically accepted and registered, which typically happens within about 24 hours of posting.

Long-haul transit. An item on a flight or moving between the Mail Exchange Centre and an overseas exchange office may go several days without a new scan, especially on long international routes.

Customs clearance. Tracking often pauses on a "held at customs" status while the destination country processes import clearance, which can take longer during peak periods.

Limited destination scanning. Once the item is handed to the destination postal service, scan frequency depends on that partner network, and some operators scan less often than Macao Post.

Ordinary unregistered mail. Letters and printed matter sent without a registered or EMS service carry no S10 number and will never show movement.

Wrong or mistyped number. A single wrong character returns no result, so the number should be rechecked against the receipt, including the two-letter prefix and the MO suffix. For online orders, the sender is the fastest first point of contact; if there is genuinely no movement for two weeks or more, contact Macao Post with the number and posting receipt.

Services and Delivery Times Compared

Macao Post organizes its trackable products into registered correspondence, parcels, and EMS, and each carries tracking while ordinary mail does not. The table summarizes the main services and typical transit times.

Delivery times are estimates, not guarantees. Actual transit depends on the destination country, customs processing, flight availability, and local delivery conditions.

Delivery and Transit Times by Destination

Macao is a compact territory, so domestic delivery is fast: local mail within Macao usually arrives in 1-2 business days across the Macao Peninsula, Taipa, and Coloane. International transit varies widely by product and destination.

EMS to nearby Asian destinations such as Hong Kong, mainland China, Taiwan, Japan, and South Korea often takes 3-7 business days, while EMS to Europe and North America typically takes 7-14 business days. Registered and ordinary international mail commonly takes 1-4 weeks depending on the destination and customs. Items routed through the mainland are frequently handed to China Post for onward processing, and shipments to and from neighboring Hong Kong connect through Hong Kong Post.

Cross-Border Customs and International Handoff

Since 1 September 2020, senders of EMS, parcels, registered small packets, and small packets from Macao must submit an electronic customs declaration before posting, except for items to mainland China, Hong Kong, and Taiwan. Customs information is submitted in English through the CTG declaration portal (cds.ctt.gov.mo) or the Macao Post mobile app, and must include the recipient's address, category of item, quantity, value, and weight.

"Mail items (except letters) without the corresponding electronic customs declaration may be rejected by the destination's customs, be returned, or be subject to delay in processing." (Macao Post, News, 2020.)

In the destination country, parcels and EMS items pass through import customs, where the recipient may need to pay duties or taxes before release. Tracking can pause on a "held at customs" status during this stage. Once clearance is complete, the destination postal service resumes scanning and arranges final delivery.

Which Countries Does Macao Post Deliver To?

Macao Post international tracking reaches destinations across every region because Macao Post is a member of the Universal Postal Union and, through the UPU framework, hands each item to the destination country's postal operator for final delivery. Within Macao, CTT delivers across the whole SAR through a network of about 15 post offices plus the General Post Office at Senado Square, a central Mail Exchange Centre, roughly 40 stamp vending machines, and around 61 pillar boxes across the peninsula and islands.

Internationally, EMS and registered items provide the most complete tracking, while ordinary mail may show limited or no scans once it leaves Macao. Because Macao sits within Greater China, many items flow through the mainland and are carried onward by China EMS or China Post. Typical destination groups include:

• Domestic: Macao Peninsula, Taipa, Coloane, and the Cotai area.

• Greater China and Asia Pacific: mainland China, Hong Kong, Taiwan, Japan, South Korea, Singapore, Australia.

• Europe: Portugal, the United Kingdom, Germany, France, Spain.

• North America: the United States and Canada.

• Rest of world: most UPU member territories via the destination postal operator.

Returns, Inquiries, and Claims

Registered mail, parcels, and EMS include an inquiry and compensation framework, so a lost or damaged trackable item can be the subject of a formal claim. For a delayed or missing item, the tracking number should be rechecked and retried after 24 hours, then followed on a universal tracker to capture updates from the destination carrier. If the item is still missing, the sender contacts Macao Post with the tracking number and posting receipt to open an inquiry. For EMS specifically, CTT operates a dedicated hotline and email channel for item inquiries during office hours.

Marketplace Collaborations

Macao Post regularly carries cross-border parcels for the major online marketplaces that ship into and out of Macao, so many Macao Post shipments begin as a marketplace order. Parcels from AliExpress and Temu commonly reach Macao through the mainland postal network before final delivery, while orders from Amazon and eBay may arrive via registered mail or EMS. When a marketplace order ships through Macao Post, the retailer's dispatch email carries the S10 tracking number that begins with two letters and ends in MO, and that number follows the parcel from Macao to the recipient.

What Is Macao Post

Macao Post, officially the Macao Post and Telecommunications Bureau (CTT), is a public body of the Macao Special Administrative Region government responsible for postal services and telecommunications regulation. The service was founded on 1 March 1884, when the first Macau stamps, a nine-value "Portuguese crown" series, were issued. The acronym CTT derives from the Portuguese Correios, Telégrafos e Telefones, reflecting the era when the bureau took on telegraph and telephone services alongside the mail.

Today CTT runs traditional correspondence, parcels, and EMS alongside philately, electronic services, and postal savings, and it remains a member of the Universal Postal Union, connecting this compact but busy territory to the global postal network. As a UPU member and EMS operator, Macao Post exchanges mail with postal operators worldwide, which is why an international item is followed most completely on a universal tracker that combines Macao Post scans with those of the receiving carrier.
