About Korea Post
Korea Post is South Korea’s national postal service. It delivers mail and parcels within Korea and sends EMS and registered items abroad through the international postal network.
Korea Post was founded in 1884 as a government institution and says it runs 3,300 post offices nationwide. EMS items can weigh up to 30 kg, though some countries, such as Argentina and Bangladesh, set a limit under 20 kg. Korea Post labels EMS documents with a barcode starting with EE and a CN 22 customs form, and EMS merchandise with a barcode starting with EM and a CN 23 form. EMS Premium is a separate service run with UPS, which handles delivery on part of the route, for items up to 70 kg.
Kargo Radar checks Korea Post’s international (English) tracking service, so it works best for international numbers ending in KR.
What do Korea Post tracking numbers look like?
You’ll find the tracking number on the label, the shipping receipt or the shipping details the sender gave you. The examples below only show the format.
Is the carrier detected automatically?
Numbers ending in KR are recognized in the app as “International Post” and looked up with Korea Post; the form on this page checks Korea Post directly.
How to track Korea Post packages with Kargo Radar
See where your package is in a few steps, and hear about it when the status changes.
- 01
Enter the number
Paste your tracking number into the form on this page. The form already has Korea Post selected and takes you straight to the results.
- 02
The carrier is found for you
Paste the number into the search box on the home page or into the Kargo Radar app, and the carrier is recognized from the number’s format.
- 03
Follow every event
Each scan is listed on a timeline with its date (and time, when the carrier provides one), and the overall status is summarized as one of six standard statuses.
- 04
Get notified
Save the package to your list in the Kargo Radar app and you’ll get a notification on your phone when its status changes. Packages from other carriers sit in the same list.
What do the tracking statuses mean?
Kargo Radar turns each carrier’s own status wording into six standard statuses, so packages from different carriers read the same way. Each event keeps the carrier’s own description in the history, or an English rendering for carriers that only report in their local language.
- Shipped
- The carrier has registered the shipment or picked it up from the sender. It may not have left yet.
- In transit
- The package is moving between facilities, countries or customs.
- Out for delivery
- The package is out for delivery, or it’s waiting to be collected at a branch, post office or pickup point.
- Delivered
- The package was handed to the recipient or collected from the pickup point.
- Delivery failed
- A delivery was attempted but not completed. The carrier’s next step shows up in the event history.
- Returned
- The package is on its way back to the sender, or it has already been returned.
Good to know about Korea Post statuses
Common Korea Post event descriptions and what they mean:
- Office of exchange
- The facility where international mail leaves or enters a country. “Outward” means leaving and “inward” means arriving; the status is In transit at this stage.
- Delivered to Destination Post
- The item has been handed over to the postal service in the destination country. This is a step along the way, not delivery to you, so the status stays In transit.
- Delivery complete
- The item has been delivered to the recipient.
- Unsuccessful delivery
- A delivery was attempted but not completed, so the status becomes Delivery failed.
Korea Post customer support
Korea Post has an online inquiry form for items that are not delivered, delayed, damaged or missing contents. It tells you to check the destination country’s postal site first. Your inquiry must reach Korea Post within four months for EMS, six for K-Packet and 30 days with Guarantee Service, counted from the day after posting.
By phone, Korea Post lists (+82) 1588 1300 for EMS. EMS Premium has a separate contact. Kargo Radar can look up the number, but sending that form is up to you.
Frequently asked questions
Answers to common questions about Korea Post packages.
How do I track a Korea Post package?
Paste your tracking number ending in KR into the form on this page. Kargo Radar looks it up in Korea Post’s international tracking system and lists every event.
What is EMS?
EMS (Express Mail Service) is the express international mail service that postal operators provide under agreements with each other. EMS numbers usually start with E. Whether destination scans appear depends on the destination country.
What does the KR at the end mean?
It’s the country code of the postal operator that issued the number, in this case Korea Post. The format follows the UPU S10 standard that postal services use worldwide.
How long does Korea Post EMS take?
Korea Post says EMS documents that don’t need customs formalities at the destination take 1–2 days to neighboring destinations such as Tokyo, Hong Kong and Singapore, and 2–5 days to other countries, if they’re accepted in the morning at a post office in Seoul. Merchandise can take longer: Korea Post’s expected delivery days don’t include weekends, holidays or the time an item spends in customs.
Why don’t I see events after my item leaves Korea?
Korea Post says its EMS tracking network connects with 59 countries, including the U.S., Japan, the U.K. and Hong Kong, for real-time tracking of EMS items sent there. For other destinations, scans in the destination country may not show up in Korea Post’s record after “Delivered to Destination Post.” The UPU S10 number is meant for use between postal operators, so the destination post can usually identify the item by the same number.
Is Korea Post tracking free?
Yes. Tracking on Kargo Radar is free and doesn’t require an account. Save the package in the app to get a notification when its status changes.
