I need to get a list of ISINs for all my equities tickers. All online services I checked do the opposite (convert ISIN to ticker). I need ticker to ISIN. Any solution for that?

For example, I want to get ISINs for all Nasdaq tickers.

stockmarketmba.com is the closest I found so far, but you would need to scrape the ISIN from the web page. The Quantel Api also returns ISINs (e.g. the GET /profile/{tickers} method) but does not support all the exchanges I require. Websites isin.org supports some database lookup but no ticker lookup. isin.net, isin.com are complete fake. I wonder why it is so hard to get a reliable source for this data, after all it is not very dynamic data. I am currently stuck with ISINs on my system since I use them as primary key, but I wish there was a more accessible alternative.

  • Did you use other queries / parameters?

  • No, I need only ISIN and 'profile' worked fine for me.
