Korean Clinic and Pharmacy Signs: One Formula Reads Every Door

How do you find a doctor in a country where you cannot read the word “doctor”?

In Korea, the honest answer is that the street finds one for you. Clinics here do not hide behind brass plaques and referral systems; they hang their function on the building in letters a metre tall. A commercial block near any subway station carries four or five of them stacked up the wall. The problem is not that the information is missing — it is that it is written in Hangul, and unlike the restaurant signs we covered in part two, you will hopefully never need it until the day you suddenly do.

The good news: medical signs are the most regular signs in the country. Every one of them is built from the same three slots, and — this is the part that surprised us — the reliability of the formula is written into law. Article 42 of the Medical Service Act forbids a medical institution from calling itself anything other than what it is, and forbids anyone who is not a medical institution from using those words or anything resembling them. A restaurant can name itself poetry. A clinic cannot. If a Korean sign says 의원 (ui-won), there is a licensed doctor behind that door — the word itself is regulated.

The middle slot is the only part you need

The first slot is a name — most often the doctor’s surname, sometimes a reassuring word. The last slot tells you the size of the institution (more on that below). Everything you actually need to know sits in the middle, and it always ends in 과 (gwa) — from the character 科, “department.” These are the definitions from the Standard Korean Dictionary, not our paraphrases:

The sign says	Say it	The department of…
내과	nae-gwa	internal organs, treated without surgery — fevers, stomachs, colds
외과	oe-gwa	wounds and internal conditions treated with surgery
정형외과	jeong-hyeong-oe-gwa	muscles, bones and joints — the one for a hiking injury
피부과	pi-bu-gwa	skin
안과	an-gwa	eyes — medical care, not glasses; glasses are a shop, not a clinic
치과	chi-gwa	teeth, gums and jaw
이비인후과	i-bi-in-hu-gwa	ear, nose, throat, windpipe and gullet
산부인과	san-bu-in-gwa	pregnancy, childbirth and gynaecology
소아청소년과	so-a-cheong-so-nyeon-gwa	children and adolescents

If you only memorise one row, make it 내과. It is the door for the complaints travel actually produces — fever, stomach, the cold you caught on the plane. What happens after you walk in, what it costs without Korean insurance, and why you do not need an appointment is a full article of its own.

이비인후과 deserves its moment. Five syllables that terrify beginners, until someone shows you the trick: 이 is ear (耳), 비 is nose (鼻), 인후 is throat (咽喉), 과 is department. The sign is an anatomy list. The dictionary defines it exactly that way — the field treating “the ear, nose, throat, windpipe and gullet.” Korean medical signage does not do mystery; it does inventories.

의원 or 병원 — the law draws the line at thirty beds

Both words translate as “somewhere with doctors,” and travellers understandably read 병원 (byeong-won) as the better option because it sounds bigger. It is bigger — that is the point. The dictionary is plain about the small one:

의원(醫院): 진료 시설을 갖추고 주로 외래 환자를 대상으로 의사가 의료 행위를 하는 곳. 병원보다는 시설이 작다.

Uiwon (醫院): a place equipped for consultations where a doctor treats mainly outpatients. Smaller in facilities than a hospital.

And the law is precise about where “smaller” ends. Article 3-2 of the Medical Service Act requires that a 병원 — and its traditional-medicine counterpart, the 한방병원 (han-bang-byeong-won) — be equipped with thirty or more beds. Below that line, the institution is an 의원: a neighbourhood clinic, one or two doctors, walk-in outpatients. This is why our clinic-visit article’s practical rule for a cold is to look for 의원, not 병원 — for everyday complaints, the small word is the right door, and the big one is for the day you are referred through it.

One more letter is doing quiet work in this family. 한의원 (han-ui-won) is an 의원 with 한 (韓, Korea) in front: a clinic of traditional Korean medicine — acupuncture, cupping, herbal prescriptions. It is a regulated part of the Korean medical system — the Medical Service Act ranks its hospitals alongside the others — but it is not where you go for antibiotics. If you want a Western-medicine doctor, the sign to trust is the bare 의원 with a 과-word in the middle slot.

약국 — the word that finishes the visit

A Korean clinic visit ends with a piece of paper, not a bag of pills: the 처방전 (cheo-bang-jeon), the prescription. The dictionary defines 약국 (yak-guk) as “the place where a pharmacist prepares or sells medicine” — and Korean urban planning has arranged things so that you barely need the definition. Pharmacies sit on the ground floor of the same buildings whose upper floors hold the clinics, precisely because that is where the prescriptions come from. Walk out of the lift, look for 약국 — usually on a green sign, though the word is the dependable part, not the colour — hand over the paper, done.

You may also see 약방 (yak-bang) on older shopfronts; the dictionary lists it as a plain synonym of 약국. Same place, older word.

The sign that renamed itself

Here is a small test of whether a sign system is alive: does it leave fossils? Korea’s does. The dictionary entry for 소아과 (so-a-gwa) — the old word for paediatrics — carries an unusual note: the field was officially renamed 소아청소년과, “paediatrics and adolescents,” in June 2007. Nearly twenty years later, the shorter old name is still what most people say, and you will still find it painted on plenty of buildings, because repainting a sign costs money and everyone understands the old word anyway. If you see either version, it is the children’s doctor.

We flag this one because it is the kind of thing that quietly breaks phrasebooks: a learner’s app teaches 소아청소년과, the building says 소아과, and the traveller concludes they have misread. You have not. It is the same department wearing two ages of the same name.

Taped to the glass

Two small words complete the kit, both usually on paper or an LED board at the door. 진료 (jin-ryo) means consultations — 진료중 means the doctor is seeing patients now, and a 진료시간 board lists the hours. Its opposite is the one that matters: 휴진 (hyu-jin), defined by the dictionary as the institution resting from consultations for a day or a period. A clinic door showing 휴진 on a Wednesday afternoon is not closed forever; it is closed today, and the neighbouring building very likely holds the same specialty.

Two more for completeness: 응급실 (eung-geup-sil) is the emergency room, a word we hope stays theoretical for you, and 보건소 (bo-geon-so) is the public health centre run by each district — vaccinations and public-health services rather than walk-in treatment of tourists.

If this article was readable at all, it is because the signs are phonetic and the alphabet takes an evening to learn — part one of this series makes that case in ninety minutes. Part four goes somewhere cheerier: the everyday service signs — 세탁소, 미용실, 노래방, 찜질방 — the words for laundry, haircuts and the two great Korean institutions of staying up too late.

What we checked, and what we did not

Every definition above is quoted or directly translated from the Standard Korean Dictionary of the National Institute of Korean Language, checked on 16 August 2026, and the two legal claims — the thirty-bed threshold and the restriction on medical names — are from the current text of the Medical Service Act (Articles 3-2 and 42) on the government’s law portal. We have not verified how any individual clinic operates: whether a given 의원 takes walk-ins on a given day, what it charges, or how much English is spoken inside are questions this article does not answer — costs and process are covered, with their own caveats, in our clinic-visit article. The observation that old 소아과 signs remain common on the street is ours, not a statistic. And nothing here is medical advice; it is a reading lesson for doors you may never need to open.
