undocumented

Lacking official records

Undocumented means lacking official papers or records.

An undocumented immigrant has no legal authorization to reside in a country—the term emerged as a neutral alternative to "illegal alien." Beyond immigration, undocumented describes anything without proper paperwork: undocumented transactions, undocumented software features.

In computing, an undocumented function exists but isn't described in official manuals.
