The invention discloses a short message number attribution information recognition method. The method comprises the following steps: a plurality of initial numbers are extracted to from an initial number set; the last unsubstituted character of the initial number is replaced with a substitution variable, and a substitution number is obtained; an initial number corresponding to a substitution number with the coincidence degree less than a preset coincidence degree is put in an intermediate number set; substitution numbers with the coincidence degrees no less than the preset coincidence degree are merged, and a merged number is put in the intermediate number set; all numbers in the intermediate number set are used as updated initial numbers; iteration until the times of replacing all numbersin the intermediate number set with the substitution variables are N is carried out, and the prefix numbers of all numbers in the intermediate number set obtained after iteration are selected as an output number set; and the attribution information corresponding to each prefix number in the output number set is recognized. According to the short message number attribution information recognitionmethod disclosed in the invention, the attribution information of a large number of short message numbers can be judged, and the user information acquisition efficiency and the accuracy are improved.
