System and method for identifying data fields for remote address cleansing

A computer system for recognizing and verifying data formats of received address lists for address cleansing, the system comprising one or more computer servers including a processor programmed for performing the following steps:

• storing a plurality of address file hash values associated with a plurality of known address data file profiles in a database memory, the address data file profiles including address data file formats and data field structure;
• receiving an uploaded address file from a sender over a communication network;
• identifying a received address data file profile of the uploaded address file;
• calculating a first hash value based on the identified received address data file profile;
• comparing the first hash value with the stored plurality of address file hash values to determine whether the received address data file has a known data format and structure;
• and
• if the first hash value matches one of the stored plurality of hash values, then associating the known address data profile of the matching stored hash value with the uploaded address file;
• if the first hash value does not match any of the stored plurality of hash values, then preparing a new address file profile, generating a new hash of the new profile, and storing the new profile along with the associated new hash.
