There is no famous standalone EIN tracker app category. People search for an EIN application tracker app because the EIN stalls foreign founders for weeks, and they want something to watch it.
- Your provider's portal, if they filed the EIN: the good ones show the application date, the method used, and the confirmation when the letter arrives. - The IRS itself: the official app covers the basics, and the confirmation letter stays the source of truth. - A post-formation checklist app with the EIN as a tracked milestone: it does not speed up the IRS, but it stops the application rotting in your inbox. - Judge every option on three questions: does it know foreign founders cannot apply online, does it log dates and methods, and does it say what to do if the letter never arrives?
