A CUSIP (Committee on Uniform Security Identification Procedures) number is a nine-character alphanumeric code that represents a specific security. It's used to distinguish between different securities, even if they have the same name or ticker symbol.

The CUSIP number is assigned by S&P Global Market Intelligence and is widely used in the financial industry. The CUSIP number is unique to each security and remains unchanged even if the security is merged or acquired.

In the context of mapping and conversion, CUSIP mapping is essential for ensuring that the correct securities are matched and converted. This process requires a high degree of accuracy to avoid errors and discrepancies.

You can download the CIK-CUSIP mapping from a repository that produces the link between CIK and CUSIP using EDGAR 13D and 13G fillings.

This repository is a competitor to WRDS SEC platform, and the best part is that it's free.

The mapping is generated using a robust method that's more reliable than Compustat due to backward filling of new CUSIP to old records.

You can download the mapping directly from the repository by downloading cik-cusip-maps.csv.

The repository also includes a script called dl_idx.py that downloads the EDGAR index file containing addresses for each filing.

This index file generates a full_index.csv file.

After downloading the mapping, you can clean the resulting CSV files to get the mapping.

Note that the mapping doesn't include timestamp information, which can be a problem if you need to know when the link was valid.

The reason for this is that the timestamp information can be truncated due to the timing of the filings, making it difficult to determine when the link was valid.
