South Korea uses a numeric code of 5 digits (e.g. 03185). Because leading zeros are significant, codes are always stored as strings — a code such as 03185 is not the same as 3185. Five-digit road-name based postal code.

This database currently holds 35,583 postal codes ranging from 01000 to 63644, linked to 0 building and address records. Because a single postal code can cover more than one locality or delivery point, the lookup below groups addresses by code and lets you drill into the individual records.

Postal codes matter well beyond mail delivery. Couriers, e-commerce checkout forms and address autocomplete tools rely on the postal code to route a parcel and to verify that the stated address matches the code. Addresses here are organised as Province / Metropolitan City → City / County / District → Town / Township / Neighborhood. When you look up a code here, treat the associated name as a reference point rather than a full postal address — always confirm the street and house number with the sender or recipient before shipping.

Data source: a third-party open dataset. This is an imported reference dataset, not a live government feed; CodeReff does not independently verify each record, so codes may have changed since the snapshot was taken.

Frequently Asked Questions

South Korea uses a numeric code of 5 digits (e.g. 03185). Because leading zeros are significant, codes are always stored as strings — a code such as 03185 is not the same as 3185. Five-digit road-name based postal code.
Yes. South Korea postal codes are a plain numeric string, so a leading zero is part of the code itself. A code beginning with 0 must be written and stored with that zero — it is not the same as the same digits without it.
