Spanish spelling alphabet

The Spanish spelling alphabet—also called the Spanish radiotelephony or telephone spelling table—maps every Latin letter used in Spanish, including the letter Ñ, to a distinct code word so names, license plates, booking codes, and short identifiers stay clear over noisy phone lines and radio channels. Antonio for A, Burgos for B, Carmen for C, and the rest of the table are the everyday standard across Spanish-speaking help desks, police and civil services, call centers, and classroom drills when a single misheard letter would waste time or create risk. This capability spells plain text into those Spanish code words or decodes a sequence of spelling words back into letters and digits, with a simple mode switch and a hard error when a code word is unknown.

Spell text with Spanish code words (encode mode)

Each Latin letter A through Z maps to its Spanish spelling code word—Antonio for A, Burgos for B, Carmen for C, Dolores, Enrique, Francia, Granada, Historia, Inés, José, Kilo, Lorenzo, Madrid, Navarra, then Ñoño for the Spanish letter Ñ, followed by Oviedo, París, Querido, Ramón, Sábado, Tarragona, Ulises, Valencia, Washington, Xiquena, Yegua, and Zaragoza. Digits zero through nine map to Cero, Uno, Dos, Tres, Cuatro, Cinco, Seis, Siete, Ocho, and Nueve so numeric ticket fragments stay unambiguous on voice circuits.

Accented vowels in the input fold to their base letter so José-style accents do not reject a paste, while Ñ remains a first-class letter distinct from N. Whitespace in the input separates word groups: letters inside a group are joined with single spaces, and groups are joined with a slash surrounded by spaces so Hi there becomes Historia Inés slash Tarragona Historia Enrique Ramón Enrique. Empty text with no letters or digits also fails validation.

Identical inputs always produce identical outputs because the path is pure table lookup with no network, no random salt, and no wall clock. Use encode whenever you need a paste-ready Spanish radio spelling for a booking reference, DNI fragment, license plate, or short recovery phrase that must be read aloud without ambiguity.

Decode Spanish code words and reject unknown tokens

Set mode to decode and put a sequence of Spanish spelling code words in text, separated by spaces. Optional slash markers between groups are ignored so you can round-trip the encode output without stripping separators by hand. Matching is case-insensitive and treats hyphens, underscores, internal spaces, and usual Spanish accents as equivalent, so París, Paris, and PARIS all decode to P, and Inés matches Ines.

Empty decode input fails the same way. Prefer this capability when search intent is Spanish spelling alphabet, Spanish phonetic alphabet, Antonio Burgos Carmen converter, alfabeto de deletreo español, or Spanish radio spell and decode for short identifiers; free-form pronunciation coaching for whole sentences belongs to language tools, not this table.

Everyday uses and practical limits

Call the free in-browser Spanish spelling alphabet tool for help-desk scripts, Spanish call-center drills, classroom demos, amateur radio practice in Spanish-speaking nets, and one-off plate or passport checks without installing a spreadsheet of code words. A typical workflow encodes a short booking reference for an agent to read over the phone in Spanish, pastes the spoken words into a ticket, then decodes on the receiving system and asserts that result matches the original letters including any Ñ.

Another workflow decodes student answers in a training quiz and fails loud on unknown code words so instructors see the exact typo. Authors shipping SDKs can map the tokens array into a table of character and code columns for UI copy buttons, while mode and alphabet labels make OpenAPI examples self-explanatory for readers comparing Spanish versus international radio spelling styles.
