LEI to CIN lookup for Indian companies

Last updated 2 November 2026 · by Venu Gopal Reddy Muvva, founder

Many Indian companies hold a Legal Entity Identifier (LEI) from GLEIF, and GLEIF records often carry the company's CIN as its registration number. IndianFirmData joins GLEIF, NSE, Nifty index lists and Wikidata into one record per company, so you can enrich by LEI and get the CIN, or by CIN and get the LEI. Each link stores its method (CIN, LEI, ISIN, symbol, domain or name) and a confidence score.

Steps in IndianFirmData

  1. 1. Enrich by LEI

    Call GET /api/v1/companies/enrich?lei=<LEI>, or paste the LEI in Verify an ID to check its check digits first.

  2. 2. Read the joined record

    The record shows the CIN, NSE symbol, ISIN and Wikidata id we linked, each with its source.

    Read the joined record

  3. 3. See how it was matched

    The profile's match section lists each registry record we joined and the method and confidence of the link.

  4. 4. Go the other way

    Enrich by cin=<CIN> to get the LEI, its status and its next renewal date.

Why this join is hard

GLEIF, NSE and Wikidata each use their own IDs and spell names differently. We link on shared identifiers first, because they are reliable, and only then on name and state. For listed companies without an LEI we also look up GLEIF by ISIN and exact legal name, accepting only a listed CIN or a unique exact match.

Filters you can use

Search can filter on has LEI, LEI registration status, LEI next renewal date, GLEIF entity category and whether the company has a parent entity, so you can, for example, list companies whose LEI lapses next month.

When IndianFirmData is not the right tool

If you need LEIs for companies outside India, use GLEIF's own search: our index is built for Indian companies and holds the Indian part of GLEIF only.

Questions

Is GLEIF data free to use?

Yes. GLEIF publishes LEI data under CC0, and we say so on every field that comes from it.

How often is LEI data refreshed?

Public sources refresh daily, and entity status has a 7-day freshness limit.

What if the LEI is not in your index?

The enrich call returns no match and costs nothing.
