K4ZSN HAM

✅ Available for a vanity request — K4ZSN was last held in the 1990s (license expired Jun 10, 1996), before the FCC's online records begin, so the two-year wait is long over. Confirm in the FCC's vanity system before applying.
1x3 call: Technician, General, Advanced and Amateur Extra licensees can request it. No pending applications list it.
Last requested Apr 27, 2021 as choice 4: not granted, that applicant got W4PFT instead.

Not in the FCC's online records (1999 → now), but held before then: see below.

Held Before 1999

K4ZSN in the 1993–2003 Callbooks
From the FCC amateur database as published on the QRZ! callsign CD-ROMs, 1993–2003, before and alongside the FCC's online records (which start in 1999). "Seen" dates are the first and last disc showing that record; the issue date is the FCC's, so it can be a renewal of an even older license.
K4ZSN in the Printed Callbooks, 1909–1997
From scanned copies of the printed callbooks (government lists from 1913, then the Radio Amateur Callbook to 1997), read by OCR, so names and streets can carry typos. Each line is one or more editions in a row showing the same name at the same address.
