How to match PERMNOs (from CRSP) to RICs

lifeplsbenice2me

Hi,

I have a list of PERMNOs (from CRSP) and I’d like to know if there’s an easy way to find the corresponding RICs for these identifiers. My understanding is that each PERMNO should map to one unique RIC. For example, I have PERMNOs 10104 and 10107 — how can I match these companies with their respective RICs?

Thank you!

Thank you for reaching out to us.

I checked and found that the PERMNOs are not available in our Database. You need to contact the helpdesk support team via LSEG Support to confirm this.

Our libraries support PermIDs.

I think you need to use tools from CRSP to covert PERMNOs to CUSIPs or tickers. Then, you can use our library to convert CUSIPs or tickers to RICs.
