Methods and systems for predicting statistically probable systematically assigned identifiers are disclosed, as are methods and systems for determining the likelihood that a systematically assigned identifier provided by a purported assignee of the identifier is legitimate. In one example, determining the likelihood of legitimacy includes determining the likelihood that the provided identifier is a valid identifier and determining the likelihood that the provided identifier was assigned to the purported assignee. To accomplish this validation, the present disclosure employs patterns of assignment discernable for systematically assigned identifiers in combination with statistical methods.
