I been a radio techie for decades. In 2007 I decided to get the ham license. After I tested and passed, I found out the fine print. No license without the FCC forcing you to divulge your SSN. Another ham operator explained to me, it’s all about the child support & enforcement network the feds have setup to stomp on every citizen with. Big brother is every aspect of our lives.
I believe if you go online to the FCC site and get your FCC ID number before the test you can use that instead of your SSN.
