The embodiment of the invention provides an address prompting method and device. The method comprises the steps of carrying out word segmentation on to-be-processed addresses according to a preset address format rule, and generating word segmentation information; determining search data according to the word segmentation information, wherein the search data at least comprises the address information with the lowest level in the word segmentation information; and establishing a prompting address set through addresses matching the search data in an address database, wherein the prompting address set comprises data designed to be pushed to a terminal. According to the method and the device, the address information (administrative districts with the lowest level and/or point of interest information) with the lowest level is taken as the search data, so other data with a low information content in the to-be-processed addresses is prevented from being processed excessively, and the search efficiency can be improved. According to the method and the device, the addresses related to a user address in the massive address data can be prompted accurately and efficiently.
