An address consolidating system that has a name and address database where duplicate names and address are consolidated by matching name and address and e-mail address simultaneously. The address consolidating system utilizes a database along with off-the-shelf and custom proprietary software. There are two segments to the database: records with name and address data (which may or may not include e-mail address data), and records with e-mail address data (which may include incomplete portions of associated name and address data). Periodically the database is updated with new or corrected name, address, or e-mail information, or with new records obtained from other database lists.
