I remember my ICQ number (1998-2002ish), my compuserve id (1996-1998), and my first house phone number (1984-1993), and two school friend's hosue numbers (1993-2000), and the Live and Kicking number (081 811 8181, which dates it to 1990-1995). I can also tell you, just about, my mobile phone number (2006-now) and wife's (2003-now). I can also tell you both my passport numbers and expiry dates. Couldn't tell you my home phone number, let alone anybody else's. You remember numbers you use a lot, I have no idea why I remember by ICQ number though.
