Thailand Post Tracking

Thailand Post tracking follows registered mail, parcels, and EMS express items across a network that handled national mail volumes through more than 1,300 post offices and around 3,300 licensed outlets. Thailand Post Company Limited (ไปรษณีย์ไทย) issues a 13-character tracking number on every registered, parcel, and EMS shipment, both domestic and international. Paste that Thailand Post tracking number into the tracker on this page to see each scan from acceptance to delivery, including the handoff to the destination postal service on cross-border items.

Thailand Post Tracking Number Format

A Thailand Post tracking number is a 13-character code in the Universal Postal Union (UPU) S10 standard: two letters, nine digits, and the ISO country code TH at the end, for example EE123456789TH. The first two letters are the service indicator, the middle eight digits are the serial number, the ninth digit is a check digit calculated from the serial, and the final TH marks Thailand as the country of origin.

The same number is called a tracking number, an item number, or a barcode number depending on where it appears, but for S10 items these all refer to the single 13-character code. A store order number (the reference an online shop assigns to a purchase) is not the same thing and cannot be traced on the postal network; only the S10 number returns Thailand Post scans. Ordinary, unregistered letters carry no S10 number and cannot be tracked at all.

Where to Find Thailand Post Tracking Number

The Thailand Post tracking number is printed wherever proof of posting is issued, and for online orders it is passed on by the seller. It is the 13-character code that ends in TH.

• On the receipt handed over at the post office counter when the item is accepted.

• On the parcel label or the registered mail slip attached to the item.

• In the shipping confirmation email or order page from an online store that shipped with Thailand Post.

• On the ThailandPost or track-and-trace app if the shipment was booked through a Thailand Post account.

For marketplace orders the seller usually shows the postal number once the parcel is dispatched. If only a shop order reference is visible, wait until the seller marks the item shipped, because the store order number will not return postal scans.

Thailand Post Tracking Number Example

The two-letter prefix signals the service class. The table below lists the S10 prefix ranges Thailand Post uses, with an example number for each. Prefix letters follow the UPU convention, so the service group is reliable, but the exact sub-letter (RR versus RA, CP versus CY) does not by itself guarantee a specific product tier.

Any 13-character code ending in TH can be entered into the tracker on this page. The two-letter service group above is reliable; treat any finer prefix-to-tier reading as a common pattern, not a guaranteed rule, because the sub-letter alone does not confirm the exact product.

Thailand Post Tracking Status Guide

Thailand Post records a scan at each handling point, and the status text describes where the item is in its journey. The table below explains the most common Thailand Post tracking statuses on domestic and international items.

Why Thailand Post Tracking Is Not Updating or Not Working

Thailand Post tracking often looks stuck when the item is still moving between scan points rather than lost. The reasons below cover the most common cases where updates pause or the number returns no information.

Awaiting the first scan: A newly created label may show no information until the item is physically accepted and scanned at a post office, which can take a day or two after the seller books it.

In transit between hubs: Domestic items are scanned at handover points, so several days can pass with no new event while the parcel travels between a sorting center and a logistics hub.

Handoff to the destination carrier: On international items the number passes from Thailand Post to the destination post under the UPU network, and there is often a gap before the foreign carrier records its first scan.

Customs clearance: An item held for customs in the destination country can sit for several days without a new scan while it is inspected or waits for duty or tax payment.

Wrong number or missing detail: A mistyped prefix, a missing digit, or a store order number entered instead of the S10 number will return no result; recheck the 13-character code ending in TH.

Genuinely delayed: During major sale events and holiday peaks, scanning and delivery slow down across the network. If an item shows no movement for two to three weeks, the sender should raise it with Thailand Post, and for international parcels the destination carrier may also need to be contacted.

Services and Delivery Times Compared

Thailand Post runs distinct mail and parcel products for domestic and international shipping, and every service in the table below is tracked. Delivery windows are estimates that vary with destination, customs, and peak-season volume.

Delivery and Transit Times Across Thailand and Abroad

Domestic EMS reaches most Thai provinces in 1-2 business days, the fastest tracked option Thailand Post offers. Registered mail and domestic parcel post typically take 2-5 business days, with the longer end applying to remote districts and islands served through licensed outlets rather than a main post office.

International timing depends on the service and the destination. EMS World express usually delivers in 3-14 business days, reaching regional hubs such as Singapore, Malaysia, and Hong Kong at the fast end and long-haul destinations in North America and Europe toward the slower end. Standard international parcel and registered mail generally take 1-4 weeks, driven largely by the destination country's customs handling and its local postal network. Public holidays in Thailand and in the destination country, along with major sale peaks, extend all of these windows.

Returns, Claims, and Undelivered Items

When delivery cannot be completed, Thailand Post records a failed attempt and holds the item at the local post office for the recipient to collect, then returns it to the sender if it is not claimed within the holding period. Registered and EMS items capture a delivery scan and, where applicable, a signature, which serves as proof of delivery.

For a lost or damaged registered, insured, or EMS item, the sender files a claim with Thailand Post, keeping the posting receipt with the S10 number as evidence. Insured services (the CV international range and domestic insured options) allow compensation up to the declared value, while ordinary registered mail carries a standard limited indemnity. International claims can take longer because they may involve the destination postal operator as well.

Which Countries Does Thailand Post Deliver To?

Thailand Post international tracking follows an item from acceptance in Thailand, through the outward office of exchange, and on to the destination post, which then records the delivery scans. Thailand joined the Universal Postal Union on 1 July 1885, and Thailand Post is a member of the EMS Cooperative, so its EMS World and tracked parcel services connect to the postal networks of nearly every country worldwide.

Domestically, Thailand Post covers all 77 provinces, from Bangkok and the central plain to Chiang Mai and the northern region, the northeastern Isan provinces, and the southern peninsula down to Phuket, Songkhla, and the island destinations, using more than 1,300 post offices and around 3,300 licensed outlets. Internationally, once a parcel leaves Thailand the destination operator handles final delivery, for example USPS in the United States, Royal Mail in the United Kingdom, Canada Post in Canada, and neighboring operators such as Malaysia Post, Laos Post, Cambodia Post, and Vietnam Post across mainland Southeast Asia.

• Domestic: all 77 provinces of Thailand, including Bangkok, Chiang Mai, Khon Kaen, Nakhon Ratchasima, Phuket, and Songkhla.

• Asia Pacific: Malaysia, Singapore, Laos, Cambodia, Vietnam, Indonesia, China, Japan, South Korea, Australia.

• Europe: United Kingdom, Germany, France, Netherlands, Italy.

• North America: United States, Canada, Mexico.

• Middle East and beyond: United Arab Emirates, Saudi Arabia, and further UPU member destinations.

Regional shipments often connect with neighboring posts such as Singapore Post, a common transit and destination point for parcels moving through Southeast Asia.

Cross-Border Customs and International Handoff

Every parcel leaving Thailand travels with a customs declaration (the CN22 or CN23 form) describing the contents and declared value. On arrival, the destination country's customs authority may assess duty or tax before the item is released, and that step is the most common cause of a pause in tracking, because no new scan appears while the parcel is under inspection.

After the outward office of exchange dispatches the item, the S10 number is shared with the destination post under the UPU network, and the local carrier records the import, customs, and delivery scans. Because the handoff can create a gap between the last Thai scan and the first foreign scan, a universal tracker that follows the number across both systems shows the full journey in one place. Duties and taxes, where charged, are the recipient's responsibility and are set by the destination country, not by Thailand Post.

Marketplace Collaborations

Thailand Post is a core delivery and returns partner for Thailand's e-commerce platforms, which drove much of its parcel growth as online shopping expanded. The country's two dominant marketplaces, Shopee and Lazada, route many domestic orders through Thailand Post alongside private couriers, and their parcels move under EMS and parcel-post S10 numbers that track on this page.

Thailand Post also handles a large share of inbound cross-border e-commerce as the last-mile carrier for international marketplace orders. Parcels from AliExpress, along with Temu and Shein, frequently arrive in Thailand and are delivered by Thailand Post after clearing customs. On the export side, more than 10,000 Thai sellers use eBay to reach international buyers, shipping many of those orders through Thailand Post's EMS World and international parcel services.

What Is Thailand Post?

Thailand Post Company Limited is the national postal operator of Thailand, established on 4 August 1883 by King Chulalongkorn (Rama V) as the Post and Telegraph Office. Siam joined the Universal Postal Union on 1 July 1885, beginning its own international postal service. The postal function later sat within the Communications Authority of Thailand, and on 14 August 2003 the government split that authority into two companies, creating the present-day Thailand Post Company Limited and CAT Telecom.

Thailand Post is a state enterprise owned by the Ministry of Digital Economy and Society, headquartered in the Lak Si district of Bangkok. The company employs around 24,000 people and operates 19 logistics centers, more than 1,300 post offices, and roughly 3,300 licensed outlets nationwide. It connects Thailand to the global postal system through the Universal Postal Union and the EMS Cooperative, delivering domestic mail and parcels and handing international items to destination posts worldwide.

Whichever Thailand Post tracking number is on the receipt or label, it can be followed with the universal tracker on this page, across both domestic services and international parcels after they pass to the destination carrier.
