Converts text to numerical codes and decodes numerical codes back to text using various number-to-letter encoding systems.
A numerical code translator converts letters and words into their corresponding number values, or decodes numbers back into readable text. The most common system assigns A=1, B=2, C=3 through Z=26, but other encoding methods like ASCII values, binary, and phone keypad codes are also widely used.
Numerical codes are used in puzzles, escape rooms, geocaching, cryptography education, and secret messages. Whether you need to translate a number code to letters, convert words into numeric sequences, or decode a message someone sent you, this tool handles the conversion instantly.

Each letter of the alphabet is assigned its position number: A=1, B=2, C=3, and so on up to Z=26. To encode a word, replace each letter with its number. To decode, convert each number back to its corresponding letter. Spaces between words are typically marked with a slash, zero, or double space.
Look at the number ranges for clues. If all numbers are between 1-26, it's likely A=1/Z=26. If numbers are in the 65-122 range, it's probably ASCII. If you see only 0s and 1s in groups of 8, it's binary. Numbers like 21, 22, 23, 31, 32 suggest phone keypad encoding.
In the A=1/Z=26 system, spaces are represented by the word boundary marker you choose (slash, pipe, zero, etc.) and punctuation is typically omitted. In ASCII, binary, and hexadecimal modes, all characters including spaces and punctuation have their own codes and are fully preserved.
Yes. Most puzzle and escape room number codes use the simple A=1, Z=26 system. Paste the number sequence into the input, set the direction to decode, and match the delimiter to whatever separator appears in your code (dashes, commas, spaces, etc.).
