W4LMZ HAM
✅ Available for a vanity request — W4LMZ was last held in the 1990s (license expired Dec 20, 1993), 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.
Not in the FCC's online records (1999 → now), but held before then: see below.
Held Before 1999
W4LMZ 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.

W4LMZ 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.
