While applying for an ISSN, applicants are asked to provide publisher name, country/city, contact info and editor name. How/where can I look up an ISSN number to get these info?

Of course for a single ISSN number, I can google, find the journal site and contact them via the website. But I am doing a research on a big number of ISSNs.

Moreover, how can I be sure it is not a fake number?!! Anyone can comeup with an 8 digit number, and call it an ISSN! IS there a main ISSN portal/service, where I can lookup ISSN numbers?

    See issn.org/understanding-the-issn/the-issn-international-register for access options. It requires subscription; it is not freely available online. You could also have found this information from Wikipedia: en.wikipedia.org/wiki/… :) Commented Dec 4, 2014 at 20:38
  • If your research gives you DoIs for the publications, you can often scrape the ISSNs of the journals from those (typically, they are the 8 digits that follow the last '/'), and the information via dx.doi.org will normally give you information about the publisher. Commented Dec 9, 2014 at 13:10
  • Worldcat is a decent option

A partial answer:

You can check if the ISSN is 'fake' or not at this ISSN-Validator website. It doesn't provide much useful info though. All numbers entered are either 'invalid' or 'valid' with no further information given.
