The invention provides a retrieval method for a work order address of a power distribution network and a retrieval device of the work order address of the power distribution network. The method comprises the steps that a target full-spelling character corresponding to the work order address is acquired; the target full-spelling character is retrieved in a pre-stored spelling character library; if the target full-spelling character is not retrieved in the pre-stored spelling character library, a target initial letter string of the target full-spelling character can be extracted; and the target initial letter string is retrieved in a pre-stored initial letter string database, and a first candidate address corresponding to a candidate initial letter string matched with the target initial letter string can be obtained. According to the scheme, retrieval are conducted for twice in different scopes, so that wrongly writer characters, homophonic characters, character surplus, character lack and so forth appearing in client address information can be corrected automatically, and thus the correct work order address can be found rapidly and accurately. In this way, situations such as confirmation of the work order address based on repeated contact with a client, and wrong work assignment caused by the wrong work order address can be avoided, and processing efficiency of work orders of the power distribution network can be increased.
