I found this question, which has an answer, but facebook changed the token format since then, now it is something like: AAACEdEose0cBACgUMGMCRi9qVbqO3u7mdATQzg[more funny letters]ig8b3uss9WrhGZBYjr20rnJu263BAZDZD In short, you cannot infer anything from it. I also found the access token debugger, which shows the information I am looking for if you paste a token in, which is nice, but does not help
