As a surname, Cust can be linked to genealogical lineages and local landholding or governance in certain counties, though the prominence and details of individual branches vary over time.

Etymologically, the abbreviation likely arises from the longer word customer, itself rooted in trade terminology that developed with the growth of commercial activity in English-speaking regions.
