1. A method, comprising:
receiving an unverified address;
parsing the unverified address into a set of address elements using a parser;
generating a candidate address set based on the set of address elements;
determining an address comparison set from an address database based on the candidate address set using a hierarchical search, comprising:
determining whether a zip code for a candidate address of the candidate address set is within a set of zip codes associated with a city for the candidate address; and
adding a set of addresses associated with the zip code from the address database to the address comparison; and
selecting an intended address based on a distance metric between an address from the address comparison set and the unverified address, wherein a physical asset is delivered to the intended address without human-in-the loop verification of the intended address.
