SYSTEM DOCUMENTATION & REQUIREMENTS

πŸ’‘ This Skill includes scripts (resource) components.

What problem does it solve?

This Skill solves the problem of manually checking whether a company is currently active and whether its business registration details are valid according to Korea NTS public data standards.

Core Features & Use Cases

  • Business status lookup: Checks the business registration number state (e.g., κ³„μ†μ‚¬μ—…μž/νœ΄μ—…μž/νμ—…μž) and returns the key upstream fields for decision-making.
  • Authenticity validation: Verifies the business registration details using business number + opening date + representative name, with optional company/address fields.
  • Proxy-based API calling: Uses k-skill-proxy so the user does not need to hold the public API key, enabling safer, simpler integration for agents and users.

Example use case: Before adding a new vendor, confirm that their business registration number is in an active state and that the provided representative name and opening date match the official validation result.

Quick Start

Ask the agent to validate this business registration number using the opening date and representative name, for example: status for "123-45-67890" or validate for b_no "123-45-67890" with start_dt "20200131" and p_nm "홍길동".

FAQPage Schema
How do I verify Korean business registration number authenticity and status?β–Ό

You can verify business registration authenticity by checking the current status (active, closed, suspended) and validating details like representative name and opening date against NTS public data standards.

What is business registration status lookup and when do I need it?β–Ό

Business registration status lookup checks whether a company is an active, suspended, or closed business entity. It is needed for vendor onboarding, compliance checks, and pre-transaction due diligence.

Can I validate business registration details in bulk for vendor onboarding?β–Ό

Yes, business registration validation supports batching for vendor onboarding. You can process multiple business registration numbers to verify their status and authenticity efficiently.

Do I need an NTS public API key to check business registration status?β–Ό

No, you do not need an NTS public API key. The verification uses a proxy-based API calling system that handles authentication, enabling safer and simpler integration without managing keys.

What input format is required for business registration number validation?β–Ό

Business registration number validation requires strict input normalization: the business number must be 10 digits and the opening date must be in YYYYMMDD format for successful processing.

What limitations exist when checking Korean business registration status via API?β–Ό

Limitations include strict input formatting requirements for business numbers and dates, and dependency on proxy routing for API calls, which may affect processing speed during bulk validation.
