I know because I do the research as I currently use both my FAA ATP and CFMEII.
Furthermore, regards to the FCC, that doesn't expire, if you have had yours for more than 9 years, I would go to the website, seems they all expired in 2001 and a new form was issued. You can check on the website by putting your number in, if it does not find you, your radio license is expired. Form 605 is the only one that is valid. It was first issued in April 2002.
