How to interpret a CIN number

  1. LISTING STATUS – The listing status of a company in the stock market can be identified by the first letter of the CIN code. If the letter is L, then it means the company is listed, and if the letter is U, then it means that the company is not listed or unlisted.
  2. INDUSTRY CODE – The second part of the CIN number, after the listing code (L or U) is the Industry code which is represented by 5 numbers according to the industry of the company as per Registrar of Companies Industry Code. The industry codes are categorized into section, division, group, class and then sub-class. For example: 50200 is the industry code for maintenance and repair of motor vehicles where in Section G that deals with “wholesale and retail trade; repair of motor vehicles, motorcycles and personal and household goods” in which Division 50 is with respect to “sale , maintenance and repair of motor vehicles and motorcycles; retail sale of automotive fuel”,  group 501 and sub-group 5010 deals with “Sale of motor vehicles (includes wholesale and retail sale of new and used passenger motor vehicles and lorries, trailers and semi trailers).”
