fourteencharacter

Fourteencharacter is a term used in information technology to describe a string that consists of exactly fourteen characters. It may refer to a fixed-length token, an identifier, or a field constraint used in data schemas and software interfaces.

In databases and programming, fourteencharacter commonly appears as a fixed-length constraint, such as a CHAR(14) field or a validation rule that requires input to be fourteen characters long. This ensures uniform storage, indexing efficiency, and predictable parsing across systems.

Common uses include short identifiers, product codes, or API keys that must fit within a compact space. An example of a fourteen-character token is ABCDEF12345678.

Limitations include reduced readability and potential inflexibility. When designing user interfaces or interoperability with systems using variable-length fields, developers may prefer padding, truncation, or alternative lengths.

Security considerations: fixed length does not guarantee security; entropy depends on the character set and randomness used to generate the string.

Related topics include fixed-length strings, padding, and data types such as CHAR versus VARCHAR, as well as encoding issues that arise with multi-byte characters.
