How Long After a Company is Listed Does It Appear in the System?

Ariel

Hi everyone,

I am trying to determine how long it takes for a newly listed company to appear in the LSEG system. Specifically, after a company is officially listed on an exchange, how much time typically passes before its identifiers (e.g., ISIN, RIC, PermID, etc.) are available through LSEG APIs?

Is there a standard timeframe for this process? And is there an API or data field that indicates when a company was first added to the LSEG database?

Thanks in advance!

Hello @Ariel

In my experience, the new symbol becomes available before the listing becomes active. You can see and subscribe to all the instrument changes/additions etc in the RIC Change Notifications on LSEG MyAccount. The content experts can also answer the data query if you open a ticket there.
