⚠ Validating business registration numbers by hand — the algorithm is complex
⚠ Tax invoice e-Tax XML — hard to build by hand
⚠ KakaoBiz AlimTalk — writing templates that need Kakao’s prior approval
⚠ Keeping Korean haeyo-che/hapsyo-che consistent — English translation tools often get it wrong

Frequently Asked Questions

해요체 or 합쇼체 — which one is used?
Default is 해요체 (mid-formality), best for customer-facing copy, KakaoBiz AlimTalk, and Naver Smart Place posts. Formal documents (tax invoices, articles of association) auto-switch to 합쇼체.
Is the BRN validation accurate?
Yes — uses the official NTS checksum algorithm (weights [1,3,7,1,3,7,1,3,5] + 9th-digit overflow adjustment). Verified against real BRNs including Samsung Electronics (1248100998).
