Güney Kore

Q: In what language are the data and documentation provided?

The dataset provides a dual-language structure to support both local and international operations:
· Korean: Official administrative names (e.g., "부산광역시", "강서구").
· English: Official Romanized names (e.g., "Busan", "Gangseo-gu").
Important: The files are encoded in UTF-8. You must strictly use UTF-8 encoding when importing the data to ensure Korean Hangul characters are displayed correctly.

Q: What is the format of the postal code?

South Korea uses a 5-digit numeric postal code (e.g., 46705, 06000). This system replaced the old 6-digit system in 2015 and is used for all mail delivery and logistics.

Q: Why does the dataset contain over 6.4 million records?

This is an address-level (building-level) database, not just a list of postal codes.
Under the South Korean "Road Name Address" system, every single building has a unique address. The database lists every specific building number ('건물번호본번') and its corresponding postal code, allowing for precise point-level validation.

Q: Does the dataset support both Road Name and Land Lot addresses?

Yes. While the system is based on the modern road name address (using columns '도로명' ), the dataset also includes the legal dong name ('법정동명') and land lot numbers ('지번본번').
This allows you to map or convert between the old "Dong-based" addresses and the new "Road-based" addresses.

Q: What is the administrative hierarchy in the dataset?

The data follows the official hierarchy:
1. Si/Do (Province): The top level (e.g., "Busan").
2. Si/Gun/Gu (District): The secondary level (e.g., "Gangseo-gu").
3. Eup/Myeon (Town): Rural subdivisions (often empty in major cities).
4. Road Name: The specific street.

Q: What file formats are included in the delivery?

The package includes CSV and TXT formats. Due to the large volume of data, using standard spreadsheet software (like older versions of Excel) may be slow. We recommend importing the CSV/TXT files directly into a database (SQL) or using a specialized data viewer.

Q: Is this a one-time purchase or a subscription?

This is a one-time purchase. The license grants perpetual use for personal and internal business purposes.

Q: What is the refund policy?

Due to the digital nature of the product, all sales are final and non-refundable. We strongly recommend downloading the Free Sample before purchasing.
