About NatoSpellBase

Last updated July 21, 2026

NatoSpellBase is a free browser toolkit for the international radiotelephony spelling alphabet — the Alpha–Zulu list people often call NATO or ICAO. Tap a letter, spell a name into code words, or run a short quiz.

What we do

Interactive chart, text-to-code-word spelling, and practice drills. Everything is meant to run in your browser for the session. No signup wall in front of the first tap.

What we do not do

We are not a military training school, not an APCO department code book, and not a linguistics IPA site. If your agency issued a local spelling card, follow that card.
