How SelectBNBs checks a Korean accommodation permit

Korean booking listings often display a registration block near the bottom of the page. International travelers can see that text but may not know which government dataset contains the corresponding business record or how to interpret its status.

SelectBNBs built the lookup so a person or software agent can retrieve the public permit record, see its official source and timestamp, and compare the registered name and address with the listing they are considering.

1. Retrieve. SelectBNBs uses developer API access approved by Korea's Public Data Portal to retrieve all eight Ministry of the Interior and Safety LOCALDATA accommodation datasets. Each official dataset page lists development-stage access as automatic approval. This authorizes API use and is not government endorsement of SelectBNBs. The cache refreshes daily.
2. Normalize. Source fields are mapped into a consistent public record: permit category, management number, registered business name, road and lot addresses, permit date, operating status, facility fields and source timestamps.
3. Deduplicate. Records use the combination of permit category, issuing authority code and government management number as the durable key. A newer official observation replaces an older version of the same key.
4. Match. The lookup checks exact management numbers first. Names and road addresses can also identify records. A short local permit number is not treated as a central management number and may require a property name or address.
5. Report. The response returns the official permit finding, listing-identity comparison and SelectBNBs editorial status as separate fields, each with its own explanation.

Official record: Does the government register contain this business, and what status and permit category does it publish?

Listing identity: Do the name, address or listing details supplied point to that same registered business?

The permit finding is applied to an online listing only when the identity evidence matches. Ambiguous candidates are returned as ambiguous rather than selecting the first result.

A permit result is not a current safety, hygiene or quality inspection. It does not guarantee present availability or prove that a host controls the registered business. Those questions require different evidence.

The public response does not include owner phone numbers, personal owner identity, business registration numbers, family relationships, marital status, exact coordinates or raw upstream payloads.

The public form does not save the text a user pastes. The result carries a one-way input hash for request correlation without echoing the submitted text. Public access is limited to 30 requests per minute per IP address.

Live coverage and refresh timestamps are available at /api/registry/status. The request and response contract is documented in OpenAPI.

For a correction request, email hi@selectbnbs.com with the government management number, the field in question and the official source page. Do not send private owner information.

SelectBNBs can correct its parsing, matching or presentation. Changes to the underlying government record must be made by the responsible public authority.
