MCA21 company / LLP lookup

Public CIN or LLPIN search — legal name, class, registered office, directors, ROC, paid-up capital.

MCA lookup

What it does​

  • Validates CIN (21 chars, L/U + 5 industry digits + 2 state letters + 4 year digits + 3 type letters + 6 reg digits) or LLPIN (7 chars, AAA-1234).
  • Decodes the CIN's encoded fields:
    • State code → state name (KA = Karnataka, MH = Maharashtra, UW = Uttar Pradesh, etc.)
    • 3-char company-type code → 'Private Limited Company' (PTC), 'Public Limited Company' (PLC), 'OPC', 'Section 8' (NPL), 'Foreign Subsidiary' (FTC), etc.
    • Year of incorporation
  • Stub-mode generates an industry-flavoured name from the 2-digit NIC prefix (62 = Tech, 64 = Finance, 15 = Foods, 17 = Textiles, …).

What's stub / pending​

Same architecture as GSTIN search. Three modes:

  1. STUB — synthetic data from CIN-decoded fields.
  2. PROBE42 — Probe42 is a leading paid wrapper around the MCA21 V3 portal. MCA_PROVIDER=probe42 + PROBE42_API_KEY.
  3. CUSTOM — generic provider with MCA_LOOKUP_URL + MCA_API_KEY.

Why not auto-fetch from the real MCA portal? mca.gov.in's V3 master-data search uses HMAC-bound CAPTCHAs — re-submit attempts with the same captcha-HMAC pair are blocked, so OCR+replay doesn't work cleanly. The official MCA bulk-master-data API is ₹0.10/CIN paid; resellers (Probe42, Sandbox, Setu) wrap it with an API key.

Honest fallback (Path B) — on the Client onboarding form, the CIN field has a "🔗 Verify on MCA21 portal" link that opens the official View Company / LLP Master Data page in a new tab. CA enters the CIN there, sees authoritative data, types it back.
