K6ZIO HAM
✅ Never issued — K6ZIO isn't in the FCC's public license data (which starts in 1999) or the 1993–2003 callbooks, and nothing in it blocks a vanity request. Calls like this are usually granted when requested.
1x3 call: Technician, General, Advanced and Amateur Extra licensees can request it.
No pending applications list it.
Last requested Jun 30, 2026 as choice 7:
not granted, that applicant got K3ZIO instead.
The FCC has no record of K6ZIO ever being issued.
