# Find Companies

Bigdata.com Knowledge Graph tracks more than 7 million companies worldwide.

The following methods help you identify the IDs of the companies you are interested in:

* [Get companies by market identifiers](#get-companies-by-market-identifiers) (Recommended for a large list of companies)
* [Find companies by details](#find-companies-by-details)

Once you have the IDs, you can use them to filter your search queries with an [Entity query filter](../search/query_filters#entity).

<Tip>
  Knowledge Graphs IDs are stable and we recommend to persist them in your proprietary DB for quicker access.
</Tip>

## Get companies by market identifiers (Recommended)

Bigdata provides specialized methods to retrieve company information
using unique market identifiers such as ISIN, CUSIP, SEDOL, or listings.
These methods allow users to directly query the database for relevant
companies based on their identifiers.

Each of these methods accepts a list of strings as input and returns a
list of corresponding company objects or `None` for identifiers that
cannot be matched. The methods include:

* Get companies by ISINs
* Get companies by CUSIPs
* Get companies by SEDOLs
* Get companies by listings

<Tip>
  We recommend to use [Get companies by market identifiers](#get-companies-by-market-identifiers) because it accepts a list and retrieve the precise company IDs.

  The `find_companies` method is helpful to retrieve companies given user's input, but not to find IDs for a large list of companies, because each call requires a backend request, and it takes longer.

  If you still want to use `find_companies` programmaticaly for a large list of companies, the how-to guide [Threading - Find Entities](../../how-to-guides/threading_find_entities) describes a multi-threaded solution.
