1 If your company or school has purchased the EI database, you can easily retrieve it from it. Of course, when searching, make sure that the time is almost right.

2 If your company has not purchased EI database, it depends on the name of the journal that finally hired your article, and then confirm it against the list of EI journals;

3 Using Google to search your articles (generally available) will display more detailed information, including whether you are employed by EI or SCI.

There are also some special inquiry websites (which are basically charged) that can also be used.

I hope the above methods will help you.
