Checks whether a Korean business registration number, business start date, and representative’s name all match the records of the National Tax Service.
  • If any of the three does not match, the result is MISMATCH. The source does not say which item did not match.
  • Once the source answers, the call is billed whether it matches or not. Calls that do not produce a verdict return 4xx or 5xx and are not billed.
  • Additional items such as the company name, corporate registration number, or main business type are not accepted. The source matches these strictly, so a slight difference in notation would make the whole result a mismatch even when the three core items are correct.
  • If you only need the operating status (operating, suspended, or closed), use GC-KOR-BRS.
Values can be added to verdict and verdictReason. Reading verdicts
