Korea Post Tracking

Korea Post tracking follows letters and parcels sent through South Korea's national postal operator, which runs more than 3,600 post offices nationwide, from acceptance in Korea to final delivery abroad. A Korea Post tracking number covers EMS, K-Packet, registered mail, and standard international parcels, and the same number keeps working after the item is handed to the destination post. Paste any Korea Post tracking number into the tracker on this page to see its latest status.

Korea Post Tracking Number Format

An international Korea Post tracking number is a 13-character code in the Universal Postal Union S10 format: two letters, nine digits, and the country code KR (for example, EE123456789KR). The two leading letters identify the service, the nine digits are the unique item number, and every international item ends in KR because South Korea is the country of origin. Korea Post also calls this the registration number or EMS number, and the retailer or shipping receipt may label it the tracking number or consignment number.

Domestic items posted within South Korea use a different scheme: a 13-digit numeric registration number with no letters, entered as a single string. An order number from a Korean marketplace is not the same as the postal tracking number; the tracking number is issued by Korea Post once the parcel is accepted, while the order number identifies the purchase on the seller's site.

Where to Find a Korea Post Tracking Number

The Korea Post tracking number is generated when the item is accepted for shipment and is shared through the sender or the seller, not printed on the recipient's mailbox. For online orders, it usually appears in the shipping confirmation email or in the order history on the marketplace where the purchase was made. The number can be found in these places:

• The postal receipt handed over at the counter when the item was mailed.
• The shipping confirmation email or SMS from a Korean online store or marketplace.
• The order or delivery page in the buyer's account on the seller's website.
• The ePost account of the sender, if the shipment was booked online at epost.go.kr.

The order number printed on a store invoice is not the postal tracking number. Only the S10 code (two letters, nine digits, KR) or the 13-digit domestic number resolves on Korea Post and on the tracker on this page.

Korea Post Tracking Number Example

The table below lists the Korea Post number formats most commonly seen, with an example pattern and what each one indicates. The prefix letters follow the UPU S10 convention, so the first letter is the most reliable signal of the service class, while the second letter varies between items.

The prefix indicates a service class but not a guaranteed delivery speed. An E prefix reliably marks EMS, while R and C cover several economy and parcel products, so use the service named on the receipt when the exact product matters.

Korea Post Tracking Status Guide

Korea Post tracking moves through a defined set of events, from acceptance at the origin office to delivery in the destination country. International items show scans from both the Korean network and the receiving postal operator, so the status descriptions below combine both legs of the journey.

Why Korea Post Tracking Is Not Updating or Not Working

Korea Post tracking that shows no movement is usually normal, because international items scan only at set handover points rather than continuously. The reasons below cover the most common cases when tracking is not updating, not working, or appears stuck.

Awaiting the first scan. A number issued at the counter or by a seller can take 24 to 48 hours to become live. Until the item is physically accepted and processed, tracking may return no information or an error.

In transit between countries. After the item leaves the Korean office of exchange, several days can pass with no new scan while it waits for a flight and crosses borders. Long gaps between the outbound and inbound exchange-office scans are expected on international mail.

Customs clearance. Items held by the destination customs authority often sit without an update until clearance finishes. Duties, taxes, or a request for documents can extend this stage.

Handoff to the destination carrier. When the parcel passes to the local post, the same S10 number continues but the freshest scans then come from that carrier, so Korea Post's own page may lag behind the destination operator.

Wrong number or missing detail. A single mistyped character prevents a match. Confirm the code is the S10 tracking number (two letters, nine digits, KR) or the 13-digit domestic number, not the seller's order number.

Genuinely delayed. If a trackable EMS or registered item shows no movement for more than two to three weeks, the sender should be contacted first, because the sender holds the contract with Korea Post and can open an official inquiry.

Services and Delivery Times

Korea Post offers express, economy, and surface options for both domestic and international shipping, and every trackable service can be followed with a single number. The table summarizes the main services and typical delivery windows; all times are estimates that customs and peak seasons can extend.

EMS is the most predictable service, reaching Europe and North America in about 3 to 7 business days, while economy options such as K-Packet vary more with flight availability and customs. EMS accepts items up to about 30 kg (66 lb) to most destinations, and K-Packet is capped at 2 kg (4.4 lb).

Delivery and Transit Times by Region

Korea Post EMS reaches direct-flight cities fastest, with 3 to 4 days quoted to hubs such as Los Angeles, Tokyo, Paris, Frankfurt, and Hong Kong, and 4 to 6 days to other regions. Domestic delivery within South Korea is among the fastest in Asia, generally 1 to 3 business days and next-day for express items.

International windows depend on the service and destination. EMS shipments to the United States and Europe usually arrive within 3 to 7 business days, standard airmail takes about 10 to 20 days, and surface mail can run 6 to 8 weeks by sea. Regional neighbors such as Japan and China are typically the quickest destinations, matching the short transit seen on Japan Post and China Post lanes into Korea.

Customs, Duties, and International Handoff

Korea Post handles the Korean leg of an international shipment and hands the item to the destination postal operator, which then completes delivery under the same tracking number. Once the parcel leaves the Korean office of exchange, the freshest scans come from the receiving carrier, so a shipment to the United States continues on USPS, one to the United Kingdom on Royal Mail, and one to Canada on Canada Post.

Every international parcel carries a customs declaration: a CN22 form for low-value items (generally under 300 SDR) or a detailed CN23 form for higher-value or commercial goods. Customs clearance is performed by the destination country's authorities, not by Korea Post, and any import duties or taxes are the recipient's responsibility. In South Korea, inbound and outbound customs status is processed through the UNI-PASS electronic clearance system run by the Korea Customs Service.

Prohibited and restricted goods, including many lithium-battery items, aerosols, flammable materials, and country-specific banned products, cannot be sent through standard postal services. Undervaluing contents to reduce duties can lead to seizure, penalties, or return to sender.

Returns, Lost Items, and Claims

An undeliverable Korea Post item is held for pickup for about 15 business days before it is returned to the Korean sender. Recipients can inspect a parcel before signing and refuse it if the damage is visible, because a signed delivery is harder to dispute afterward.

For a lost or damaged item, the sender holds the contract with Korea Post and files the inquiry. Claims should be raised promptly, ideally within about 7 days for damage, with the tracking number, the mailing receipt, and evidence of value. EMS includes basic loss coverage capped under international conventions, and optional insurance extends protection for valuable contents. Korea Post customer service can be reached at 1588-1300 within Korea or +82-42-609-4295 from abroad, and the insurance line is +82-42-336-6898.

Which Countries Does Korea Post Deliver To?

Korea Post international tracking covers shipments to virtually every country, backed by Universal Postal Union membership since January 1, 1900, and partnerships with global carriers. EMS serves 101 countries directly, and EMS Premium, operated with UPS, reaches 182 additional destinations for more than 213 countries and territories in total.

Domestically, Korea Post covers the entire national territory through more than 3,600 post offices, from Seoul, Busan, and Incheon to rural villages across all provinces, including Gyeonggi, Gangwon, and Jeju. This density supports next-day domestic express and short 1 to 3 day standard delivery.

Common destination groups include:

• Domestic: all of South Korea, including Seoul, Busan, Incheon, Daegu, Daejeon, Gwangju, and Jeju.
• Asia Pacific: Japan, China, Hong Kong, Taiwan, Singapore, Malaysia, Thailand, Vietnam, the Philippines, Indonesia, Australia, and New Zealand.
• Europe: the United Kingdom, Germany, France, Italy, Spain, the Netherlands, and other EU countries plus Switzerland and Norway.
• North America: the United States and Canada by express and economy services.
• Latin America, Middle East, and Africa: Brazil, Mexico, Argentina, and major destinations with longer, variable transit.

Regional lanes connect Korea Post with neighboring operators such as Singapore Post for Southeast Asian delivery, with the same S10 number carrying across the handoff.

Marketplace Collaborations

South Korea has one of the world's most developed e-commerce markets, and Korea Post carries parcels for both domestic marketplaces and cross-border platforms. Coupang leads domestic online retail at roughly 37.7 percent of shoppers, followed by Naver Shopping at about 27.2 percent, with Gmarket, 11st, SSG.com, Lotte ON, and Interpark also serving large volumes. While Coupang runs much of its own Rocket delivery network, Korea Post and its EMS and K-Packet services handle a large share of the international parcels these sellers ship abroad.

Cross-border demand into Korea is dominated by China-based platforms. AliExpress and Temu each drew around 8 to 8.6 million monthly active users in South Korea in early 2024, with AliExpress's Choice service quoting 3 to 5 day delivery. Inbound parcels from these platforms often move through China Post and partner networks before final delivery, and Korea Post handles outbound Korean e-commerce headed to buyers worldwide.

What Is Korea Post?

Korea Post is the national postal operator of South Korea, a state enterprise under the Ministry of Science and ICT, headquartered in Sejong City. It was established in 1884 as Ujeongchongguk, the first modern Korean post office in Seoul, and has operated under the name Korea Post since July 1, 2000. Beyond mail and parcels, it runs one of the country's largest postal banking and insurance operations, particularly important in rural areas.

The network spans more than 3,600 post offices nationwide, supported by regional sorting and logistics centers and its online platform ePost (epost.go.kr), where customers book shipments, calculate postage, and track items. South Korea joined the Universal Postal Union on January 1, 1900, and Korea Post remains one of Asia's best-connected operators through its EMS network and its UPS-backed EMS Premium service. Pickup can be arranged at post office counters, and undelivered items are also collectible at partner points such as GS25 and CU convenience stores. Any Korea Post tracking number, domestic or international, can be followed with the universal tracker on this page.
