So I can change my info at qrz,com?
Yes and no. The FCC only requires a valid address that they can send renewal notices to. So if you change your address with the FCC, QRZ will get the update. But it must be valid.
I live in the country with no paved roads. If you try to follow directions to my street address, you wind up on a creepy dead end street with no houses. But that is the county's doing. I have my address painted on a rock there, so you know you made it to the right place. Then you have to call me.
When sending something to me through the mail, the only thing that really matters is the 4-digit number that is after the zip code. The rest of the address could say almost anything. If the 4-digit number isn't there, a letter/package doesn't make it to my PO box.
You could go rent a PO box and change your address to that box. But a PO box usually cost about $60 - $80 a year, depending on the size. Plus, the cost of gas to get your mail every day. I get my PO box for free, because I reside outside of the US Mail delivery area.
I do have vanity plates, with my call sign on them. Mostly I have found that the only ones that understand the plate are other hams. My plate starts with "K7" which totally confuses people. They always want to know why it doesn't say "K9", and what does the "MEM" mean. I have even had the police ask me what it suppose to say.
