I was gonna drag you for making such a silly flex then I realized I'm just jealous because mine was eight

Mine was 7 but I had it fur 5 years.

I also remember my compuserve id which lasted a mere 6 months over 30 years ago, And that was 10 digits.

Same like my Geocities homepage, never forget.

I feel like it's the same with your first phone number back when there were only landlines, etc. Some numbers are hard-wired.
