(adsbygoogle = window.adsbygoogle || []).push({}); trying to make a psn id with 3 letters ive seen people with them but i cant get any iv checked if people have them and it says theres no one with that id but i still cant get it wtf

I made one when the ps3 came out, didn't think much of it, and just gave it away since it had nothing on it and i thought it had no value, but now i only have a 4 letter account, no 3 letter one's.
