Hello all,

I’m trying to match an external dataset to Compustat (both North America and Global). In this dataset I have only historical CUSIPs and ISINs as security identifiers (i.e., those that were active at the time the dataset was compiled).

In CRSP there is a variable NCUSIP, which contains the historical CUSIPs, but I can’t seem to find anything equivalent in Compustat. For North American stocks, I could use CRSP’s NCUSIP variable to match the historical and current CUSIPs, but I’m still stuck on how to do this for the international stocks which are identified by ISINs.

Any ideas?

Thanks!
