Does Seoul have a single postal code?

No. Seoul has multiple postcodes. The correct code depends on the exact address, not just the city name.

Where does the postcode go in an English address?

Place the five-digit code after the city or locality, and REPUBLIC OF KOREA on the final line. Keep the building number and Romanized street name.

Are these all the postcodes in Seoul?

These are selected examples from the Korea Post address database. For another building, look up its full address in the official postcode search.
