How to Spell a Name with Nautical Signal Flags

Turning a name into a row of signal flags is a classic piece of nautical decor, for boat christenings, framed art and personalized gifts, and also a visual way to learn the phonetic alphabet that names each flag (Alfa, Bravo, Charlie...).

How the letter-to-flag conversion works

Each of the 26 letters of the alphabet has exactly one matching flag (A is always Alfa: half white, half blue; Z is always Zulu: four triangles, yellow, blue, red, black, meeting at the center), and every digit from 0 to 9 has its own triangular pennant, the same logic real ships use to spell vessel names and short messages letter by letter. Accents are ignored in the conversion (the "é" in "José" becomes the plain E flag), since the flag alphabet, like the phonetic alphabet that accompanies it, only covers the 26 base Latin letters.
Spaces between words become a visual break between flag groups, and punctuation with no matching flag (like "!" or "?") shows up as a small dashed marker, without breaking up the rest of the name. Alongside the flag sequence, the tool also generates the full phonetic reading (for example, "Julia" becomes "Juliett Uniform Lima India Alfa"), ready to copy, useful both for decorating and for anyone actually practicing the phonetic alphabet.

Examples

A boat name

Input: ORCA
Expected output: Oscar Romeo Charlie Alfa

Four flags, four completely different designs from one another.

A name with a digit

Input: PIER 7
Expected output: Papa India Echo Romeo [espaço] galhardete numérico 7

The space becomes a visual break, and the "7" uses the numeral pennant (yellow on top, red on the bottom), not a letter flag.

Full tool FAQ

What is the International Code of Signals (INTERCO)?

It's the standardized maritime flag system maintained by the IMO (International Maritime Organization) so ships of any nationality can communicate visually about safety, maneuvering and emergencies without relying on a shared spoken language.

What's the difference between a single-flag meaning and a multi-flag signal?

Do ships still use these flags today, given radio and satellite communication exist?

Why do the Alfa and Bravo flags have a different shape from the others (a forked tail)?

Do the numeral pennants (0-9) mean anything when flown alone?

Frequently asked questions

Do numbers and letters use the same kind of flag?

No. Letters use rectangular flags (except Alfa and Bravo, which are swallow-tailed); digits use triangular pennants, with a different shape and design, even when two flags share the same colors, the shape tells them apart.

What happens to spaces and punctuation when spelling out a name?

Spaces become a visual break between flag groups. Characters with no matching flag, like punctuation and symbols, show up as a small dashed marker in their place, without breaking up the sequence.

Do accented names work in the conversion?

Yes, accents are automatically stripped, so names like "José" or "André" convert normally to the J-O-S-E and A-N-D-R-E flags.
