You arrived in Korea with one suitcase.
Then you went shopping.
Now the suitcase will not close.
Skincare.
Clothes.
Souvenirs.
Stationery.
Gifts.
Snacks.
And suddenly you have a new question:
Can I just mail some of this home from Korea?
Yes.
Korea Post operates international postal services including EMS, international parcels and registered small packets, and it also provides international tracking and online shipping preparation services.
For many travelers, sending part of their shopping home can be easier than buying another suitcase and carrying everything through the airport.
Here is the practical version.
1. Look for This Word: 우체국
The Korean word for post office is:
우체국
Pronounced approximately:
ucheguk
Search:
우체국
on Naver Map or KakaoMap to find a nearby Korea Post branch.
If you are staying in a major Seoul neighborhood, you will normally find post offices throughout the city.
2. You Can Send More Than Letters
Korea Post's current international-mail system includes services such as:
EMS
EMS Premium
International parcel
Registered small packet
and online international-mail preparation through its Smart Acceptance system.
For a tourist, the main question is usually:
How fast do I need it to arrive, and how much am I willing to pay?
3. EMS Is the Easy Option to Understand
EMS means:
Express Mail Service
It is designed for international express postal delivery.
If you are sending:
Souvenirs
Clothes
Gifts
Documents
A box of purchases
and speed and tracking matter, EMS is often the first service travelers will ask about.
But availability, maximum weight and delivery conditions depend on the destination country. Korea Post maintains a country-by-country service and pricing checker for this reason.
4. International Parcel Can Be Another Option
You do not always have to use EMS.
Korea Post also offers international parcel services, and its online calculator allows users to compare categories such as EMS and parcel service by destination, weight and shipping conditions.
Ask the counter staff:
“What is the best option for this package?”
You do not need to memorize every Korean postal product before entering.
5. Small Items May Have Different Options
Korea Post also lists registered small-packet service within its international-mail system.
This may be relevant if you are mailing something much smaller than a suitcase-sized box.
However, eligibility and destination conditions vary.
Let the postal worker see:
What you're sending
Package size
Weight
Destination
before deciding.
6. How Much Does International Shipping Cost?
There is no single answer.
The price depends on factors including:
Destination country
Service type
Actual weight
Package dimensions
Insurance or additional services
Transportation surcharges
Korea Post's official calculator provides country-specific estimates.
Important
Do not rely on a blog post quoting one fixed EMS price.
International postage can change.
Check the Korea Post calculator or ask the post office on the day you send it.
7. A Big Light Box Can Still Be Expensive
Shipping is not always calculated using only the number you see on the scale.
Korea Post's current international price calculator compares actual weight with volumetric weight, and pricing can be based on the larger value.
Its published volumetric calculation uses:
Width × Length × Height ÷ 6000
with measurements in centimeters.
That means:
A huge box full of light items can still cost more than you expect.
Local Tip
Use the smallest box that safely fits your items.
8. Do Not Pack the Box Completely Before Checking Restricted Items
This can save you a lot of frustration.
Imagine carefully taping a box shut.
Then the postal worker asks:
“Is there a power bank inside?”
You say yes.
Now the box has to be opened again.
Before sealing the package, check what Korea Post allows for your destination.
9. Lithium Batteries Are a Big Problem
This is one of the most important sections of this article.
Korea Post's current international-mail restrictions state that lithium-ion and lithium-metal rechargeable batteries, including many devices containing those batteries, are prohibited through its international postal service.
Examples listed by Korea Post include devices such as:
Smartphones
Laptops
Tablets
Bluetooth headsets
E-readers
Electronic cigarettes
Some wireless chargers
Other lithium-battery devices.
So:
Do not assume you can mail your power bank home.
10. This Matters After Shopping for Electronics
You buy:
New earbuds.
A portable battery.
A small electronic gadget.
Then you decide to mail your shopping home.
Stop and check the battery.
A device that is perfectly legal to carry under airline rules may still be restricted under Korea Post's international postal rules.
Airline baggage rules and postal rules are not the same thing.
11. Aerosols and Compressed Containers Can Also Be Restricted
Korea Post lists compressed containers and various aerosol-type items among prohibited or restricted international-mail categories.
This can matter for travelers who buy:
Sprays
Certain beauty products
Deodorizing sprays
Camping products
Do not assume that because a product came from a normal Korean store it can automatically be shipped internationally.
12. Lighters Are Another Easy Mistake
Disposable lighters are listed as prohibited by Korea Post's international-mail guidance.
So the souvenir lighter you bought?
Keep postal restrictions in mind before putting it into the box.
13. Food Can Be Complicated
Travelers love sending Korean snacks home.
But food is not simply:
“Food = always okay.”
Korea Post identifies food among items that can require additional checking, and destination-country import rules can also apply.
This is especially important for products containing:
Meat
Seeds
Plant material
Agricultural products
Ask the post office before sending questionable food items.
14. Seeds and Plants Need Special Attention
Korea Post specifically notes that seeds can require quarantine documentation.
So a beautiful packet of Korean flower seeds may be a great souvenir.
It is not necessarily a simple international parcel item.
The receiving country's agricultural rules also matter.
15. Cosmetics Need Common Sense Too
Korea is one of the easiest places in the world to buy a suitcase full of cosmetics.
But international postal rules can depend on whether a product contains:
Liquids
Aerosols
Flammable ingredients
Pressurized containers
Unidentified powders
Korea Post specifically requires additional checking for certain liquids and powders and prohibits some compressed containers.
If you plan to send cosmetics:
show the actual products to postal staff before final packing.
16. Keep Products in Their Original Packaging
This can make identification easier.
A sealed commercial product with:
Product name
Ingredients
Manufacturer information
is much easier to explain than:
an unmarked bottle of mysterious liquid.
Korea Post's rules specifically flag unidentified liquids and powders for additional documentation or review.
17. You Will Need the Recipient's Full Address
Before going to the post office, save:
Recipient name
Street address
City
State/province if applicable
Postal/ZIP code
Country
Phone number if required
Do not try to reconstruct the address from memory while standing at the counter.
Screenshot it beforehand.
18. Write International Addresses Clearly
For overseas mail, use the destination address in a form that the receiving postal system can understand.
I would prepare it in English or the destination country's normal Roman-alphabet mailing format where appropriate.
Write the country name clearly.
The postal worker can help if you are unsure about the form.
19. Goods Need Customs Information
If you are sending physical goods rather than only documents, customs processing may affect delivery time.
Korea Post specifically warns that non-document shipments can take longer because of customs clearance.
Be prepared to describe:
What the item is
Quantity
Value
Purpose, such as gift or personal goods
accurately.
Do not write:
“stuff.”
20. Don't Declare Everything as a $1 Gift
Customs forms are official declarations.
Use realistic descriptions and values.
If you bought:
Three shirts
write something like:
Cotton shirts — 3
rather than:
Personal items
when a more precise description is required.
Korea Post also provides international-mail tools including HS-code search and commercial-invoice guidance for goods.
21. Taxes at the Destination Are a Different Question
Paying Korean postage does not automatically mean:
No import tax can ever be charged.
The receiving country's:
Customs threshold
Import rules
Duties
Taxes
may apply.
These rules depend on the destination country.
If you're shipping expensive purchases, check the destination country's customs rules before sending.
22. How Long Will EMS Take?
Do not use one universal number.
Korea Post provides expected delivery estimates by:
Destination
Service
Shipment conditions.
It also notes that quoted delivery periods exclude factors such as:
Weekends
Holidays
Customs-retention periods
and goods may take longer due to customs clearance.
So:
Estimated delivery ≠ guaranteed arrival date.
23. Check the Country Before Packing
International postal conditions can change because of:
Transportation disruptions
Local delivery conditions
Customs changes
Natural disasters
Temporary service restrictions
Korea Post publishes destination conditions and current international-mail notices on its EMS site.
If sending something important:
check before going to the post office.
24. Korea Post Has Online Smart Acceptance
If you want to prepare before reaching the counter, Korea Post provides an International Mail Smart Acceptance system for services including EMS, international parcels and registered small packets.
The system lets users provide shipment information in advance and then submit the item at the post office or use eligible pickup options.
For a first-time tourist, going directly to the counter is still perfectly reasonable.
But frequent or larger-volume users may find advance entry convenient.
25. There Can Be a Smart-Shipping Discount
Korea Post's current international postage calculator states that users of its international smart-shipping system can receive a 5% discount, except when postage is paid using stamps.
Whether using it is worth the extra setup depends on what you're sending.
For one postcard?
Probably not important.
For an expensive international parcel?
Worth checking.
26. Tracking Is One of the Biggest Advantages of EMS
Korea Post provides an English EMS tracking system using the shipment's international item number.
The official tracking page accepts a 13-character EMS number, with examples in the format:
EE123456789KR.
Important
Take a photo of your receipt before leaving the post office.
27. Keep the Receipt Until Delivery
Your receipt may contain:
Tracking number
Service type
Mailing date
Amount paid
Do not throw it away after walking out of the post office.
Take a picture.
Save it in your phone.
Then track the parcel until it arrives.
28. Can You Send a Postcard From Korea?
Yes.
Korea Post's postal system includes postage stamps and postcard products alongside its standard mail services.
If you buy a souvenir postcard in:
Seoul
Busan
Jeju
Gyeongju
write the destination address and take it to a post office if you are unsure how much international postage is required.
The staff can tell you the correct postage for the destination.
29. Don't Guess the International Stamp Price
Postage depends on the type of mail and destination.
Rather than covering a postcard with random stamps:
Take it to the post office.
Say:
“To Canada.”
or:
“To Australia.”
and let the staff calculate the correct international postage.
30. Korean Stamps Can Be Souvenirs Too
Korea Post operates a dedicated stamp portal and regularly issues Korean postal stamps.
So if you enjoy:
Korean design
History
Traditional culture
Collectibles
buying an extra stamp to keep can be a small souvenir in itself.
31. Useful Korean Words
Save these:
Post office
우체국
International mail
국제우편
EMS
EMS
Parcel
소포
Postcard
엽서
Stamp
우표
I want to send this overseas.
이거 해외로 보내고 싶어요.
How much is it?
얼마예요?
How long will it take?
얼마나 걸려요?
But remember:
You can also simply show the destination country and address on your phone.
32. What I Would Bring to the Post Office
Before leaving the hotel:
Bring the item
Preferably not permanently sealed yet if you're unsure about restrictions.
Recipient's address
Saved on your phone.
Recipient phone number
If required.
Item list
Especially if the box contains several products.
Approximate purchase values
Useful for customs declarations.
Payment method
Plus a backup.
Passport
It is sensible to carry identification when handling international shipping.
33. Pack After Checking the Problem Items
If the box contains only:
Clothing
Stationery
Ordinary nonrestricted souvenirs
packing can be fairly simple.
If it contains:
Electronics
Batteries
Cosmetics
Food
Aerosols
Seeds
check the restrictions before sealing everything.
Korea Post publishes a detailed item-by-item restricted and prohibited list specifically for international mail.
34. My Favorite Use Case: Sending Shopping Home
Imagine this.
You have five days left in Korea.
Your suitcase is already full.
You still want to visit:
Seongsu.
Olive Young.
Traditional markets.
Souvenir shops.
Instead of buying another suitcase immediately:
Option
Send a box of items you no longer need during the trip.
For example:
Souvenirs
Gifts
Clothes
Stationery
Then continue traveling with less luggage.
Just make sure every item is eligible for international mail.
35. What I Would Not Mail
I would keep these with me unless I had specifically verified the postal rules:
Passport
Cash
Credit cards
Essential medication
Expensive irreplaceable items
Electronics with lithium batteries
Power banks
Important travel documents
Your flight home and your postal shipment are two separate systems.
Do not put something essential to your trip in a box heading overseas.
36. Post Office Hours Can Vary by Branch
Do not assume every Korea Post branch has identical opening hours.
Check your specific branch before walking there with a heavy box.
Korea Post's international-mail customer center currently operates 09:00–18:00 on weekdays and is closed on Saturdays and public holidays, while individual branch service hours should be checked separately.
37. Service Availability Can Change Temporarily
This is particularly important for international shipping.
Korea Post's EMS homepage publishes current notices on temporary:
Pickup suspensions
Country delays
Transportation disruptions
Destination restrictions.
So if mailing your box is essential:
check the current notice before your final day in Korea.
38. Don't Leave Shipping Until the Morning of Your Flight
This is my biggest practical recommendation.
If your flight leaves tomorrow morning, that is not the ideal time to discover:
Your item is prohibited
You need different packaging
The post office is closed
The service to your country is restricted
Your parcel costs much more than expected
Ship things at least a little earlier in your trip when possible.
Simple Decision Guide
Just a postcard?
Go to the post office and ask for international postage.
Small nonurgent item?
Ask about available small-packet or parcel options.
Want faster international delivery and tracking?
Ask about EMS.
Large lightweight box?
Remember volumetric weight may affect the price.
Contains a battery?
Check first — lithium battery restrictions are strict.
Contains food, seeds, cosmetics or sprays?
Show the items and verify restrictions before sealing.
5 Things to Remember
1. Search 우체국
That's “post office.”
2. EMS is not the only option
Korea Post also offers international parcels and registered small packets.
3. Shipping price depends on weight, size and destination
Large boxes can be charged using volumetric weight.
4. Check restricted items first
Especially batteries, aerosols, food and similar products.
5. Keep your tracking receipt
EMS can be tracked online with the international item number.
A Local's Final Tip
Do not let your suitcase decide what you can buy in Korea.
If you've bought too much:
you have options.
But do not simply fill a box with everything you bought and assume Korea Post will accept it.
Before sealing:
**Check the batteries.
Check the liquids.
Check the food.
Check the destination rules.**
Then take the box to:
우체국
Ask the staff which international service makes the most sense.
Get the tracking number.
Take a photo of the receipt.
And enjoy the rest of your trip without trying to sit on your suitcase to make the zipper close.
Welcome to Korea — from a local.
