An improved method for cleansing a plurality of address records in an address record file. The method checks an address record for an associated cleansing date. The method determines whether the associated cleansing date has expired. If the address record has no cleansing date, or if the cleansing date is expired, then an address cleansing routine is applied to the address record. Also, a new cleansing date is added to the address record based on a current date. If the cleansing date for the address record has not expired, then the cleansing routine is omitted, adding the record to the USPS statistics, and processing of the list continues. An address cleansing report is generated indicating a number of address records that were cleansed. In the preferred embodiment, the step of adding the new cleansing date to the address record includes a step of securing the cleansing date from unauthorized changes or tampering. The step of determining whether the associated cleansing date has expired will then also include a step to access secured cleansing dates in the address records.
