Vanity Call Sign
A special amateur radio license call sign that you request from the FCC, rather than accepting the sequential call sign issued when you first license. The FCC maintains a list of call signs available for vanity request, organized by format and operator class eligibility. This tool searches that list to help you find candidates before you file your $35 application.
Call Sign Groups (A, B, C, D)
Vanity call signs are divided into four groups based on their format (the number of prefix and suffix letters around a middle region digit).
Group A: 1×2, 2×1, and 2×2 formats
The most compact formats. Examples: W1AW (one-letter prefix, two-letter suffix), AA1A (two-letter prefix, one-letter suffix), AA0AA (two-letter prefix, two-letter suffix). Eligible for Extra class only. The most desirable call signs, available in the smallest number. The prefix must start with K, N, W, or A (for the A-initial variant of the 2×2 format).
Group B: 2×2 format
Two-letter prefix, two-letter suffix. Example: KB0AA. Eligible for Advanced class and higher (Advanced or Extra). The prefix must start with K, N, or W.
Group C: 1×3 format
One-letter prefix, three-letter suffix. Example: K4ABC. Eligible for General, Technician Plus, Technician. The prefix must start with K, N, or W. Much larger pool than Groups A and B.
Group D: 2×3 format
Two-letter prefix, three-letter suffix. Example: KA4ABC. Eligible for Novice class and higher (all classes except those ineligible). The prefix must start with K or W. The largest pool by far, with hundreds of thousands of candidates.
Operator License Classes
The FCC issues amateur radio licenses at six different proficiency levels. Your class determines which call sign groups you can request. This tool supports all six classes, including legacy classes no longer issued but still held by existing licensees.
Novice (N) — Legacy
The lowest FCC amateur radio class, discontinued in 2000. Licenses issued before that date are still valid and may be renewed. Eligible for Group D only.
Technician (T)
The current entry-level amateur radio class. Obtained by passing a 35-question written exam. Eligible for Groups C and D.
Technician Plus (P) — Legacy
A transitional class that existed between Technician and General, discontinued in 2000. Still held by some licensees. Eligible for Groups C and D, same as Technician.
General (G)
Mid-level class requiring a harder written exam than Technician. Grants access to more frequency bands and operating modes. Eligible for Groups C and D.
Advanced (A)
Higher class requiring an even more difficult exam. Grants access to additional frequency bands. Eligible for Groups B, C, and D.
Extra (E)
The highest amateur radio class, requiring the most comprehensive exam. Grants access to all amateur frequencies and modes. Eligible for Groups A, B, C, and D — the full set.
Availability Status
Search results are divided into two categories based on when you can actually file the FCC application.
Available now
The call sign can be requested in your FCC vanity application today. Either the call sign has never been issued, or its previous license has expired and the FCC's two-year holding period (from 47 CFR 97.19) has passed. You can file immediately if your license class permits the group.
Opening soon
The call sign will become available within your selected horizon (default: 30 days). Its previous license expired recently or will expire soon, and the FCC's two-year holding period will lapse on the date shown. You cannot file until that date, but you can plan ahead or come back to this tool on that date to file immediately.
The date shown is our best estimate from the FCC's license records. Confidence is noted: High confidence means anchored on an expired license's expiry date; medium confidence means anchored on a mid-term cancellation (roughly 6.7% of real re-grants happen sooner than predicted); low confidence means limited data.
Score and Distinctiveness
Each call sign is scored on how distinct it sounds when spoken over a radio channel, using the NATO phonetic alphabet. Higher score means easier to copy correctly.
NATO Phonetics (Spells)
The standard way to spell out a call sign over radio. A call sign like K4ABC is spoken as "Kilo Four Alfa Bravo Charlie". The tool shows these phonetic words as small badges next to each call sign. In poor conditions, letters get confused — B/D/P/T are the classic pairs — while their phonetic equivalents (Bravo/Delta/Papa/Tango) are much more distinct.
Distinctiveness Score (0–100)
Measures how easy the call sign is to copy correctly on a noisy SSB (single-sideband) radio channel. Based on published edit-distance analysis of the NATO/ICAO phonetic alphabet. Higher score means the phonetic words are more phonetically different from each other, reducing confusion.
Example: K4ABC has a high score because Alfa, Bravo, and Charlie are all very different sounding. K4ADD would have a lower score because Delta and D sound similar. The filter lets you exclude low-scoring results if you want to prioritize copyability on the air.
Region Digit
The single digit in the middle of the call sign (0–9), representing one of ten US call regions. Example: the 4 in K4ABC. All continental US licensees can hold any region digit; mainland vanity call signs have no address requirement. Choose the region that matches the format you prefer, or simply pick your favorite digit.
How the Tool Works
This tool maintains a local copy of FCC ULS data (updated periodically from the FCC's database). It searches that data for call signs matching your filters and estimates which ones are claimable by analyzing license status records. The FCC is the final authority on whether a call sign can actually be issued when you file — this tool is an aid for planning only.
No accounts, no tracking, and no submission to the FCC from here. You handle the filing yourself on the FCC website.
