Phone number detection method, device and system and medium

The embodiment of the invention provides a telephone number detection method, device and system and a medium. The method comprises the following steps: encoding a telephone number to be detected to obtain an encoding vector; the coding vector is split into at least two sub-vectors, and the at least two sub-vectors comprise a number attribution sub-vector and a user number sub-vector; and determining that each sub-vector in the at least two sub-vectors meets a preset condition, and judging the telephone number to be detected as a normal number. Through some embodiments of the application, the accuracy of telephone number detection can be improved, the detection cost is saved, and the detection efficiency is improved. 本申请实施例提供一种电话号码检测的方法、装置、系统及介质，该方法包括：将待检测的电话号码进行编码获得编码向量；将所述编码向量拆分为至少两个子向量，其中，所述至少两个子向量包括号码归属子向量和用户号码子向量；确认所述至少两个子向量中的各子向量均符合预设条件，则将所述待检测的电话号码判断为正常号码。通过本申请的一些实施例能够提升电话号码检测的准确性，节约检测成本，提高检测效率。
