CRSP has a nice, permanent identifier system for securities known as "permno"s. I don't have access to a Bloomberg terminal, but am considering the investment. Does the Bloomberg terminal know these identifiers?

What about other identifiers? I'm sure it know CUSIPs. What about Compustat's "GVKEY"s?

I am not an expert on the Bloomberg Terminal. But just looking at it now I see it knows the CUSIP, the ISIN, the SEDOL, the WPK (wertpapierkennummer) and the SICOVAM. I don't believe it knows the CSRP-permno as far as I know. It does not do a particularly good job of linking to other information systems, being more of a self contained system itself. But perhaps there are special functions for that purpose that I don't know .
