Data Services Inc.’s Consumer and Business Merge/Purge proprietary algorithms provide high quality address duplicate identification for U.S., Canadian, and International data files. Duplicate Identification Levels:  Consumer / Individual Level – one mail piece per person  Consumer / Household – one mail piece per address allowing for different surnames  Consumer / Residential – one mail piece per address  Business – allows for a defined number of contacts at a business address The goal of any merge/purge system is to merge one or more input files, compare the records, eliminate duplicates, and purge unwanted records. In theory, this process is fairly simple; you look at a pair of records and if they appear to be duplicates, you mark them as such. Of course you would need to keep track of the number of duplicates identified, which ones you decide to keep, etc. You would also want to keep track of such statistics based on the key codes of the records. A person can do the job described above much more accurately than any computer system, as long as the number of records being compared is relatively small. A file of 10 records would involve 45 record-to-record comparisons. As the number grows, an individual cannot keep up with the task. For example, a file of 100 records requires 4,950 comparisons, and a file of 1000 records requires 499,500 comparisons. This is where a computerized system comes into play. Text Font The Merge/Purge algorithms may be tightened or loosened to meet specific needs. Tightening the algorithms will require duplicates to be fairly similar; loosening the algorithms will allow duplicates to be a bit more different. The accuracy and standardization of addresses significantly affects the ability of the Merge/Purge process to compare like records and identify duplicates. To optimize the Merge/Purge process and enable the best possible duplicate identification, we strongly recommend that you take advantage of our suite of address hygiene products: U.S. Address Hygiene  U.S. Address Standardization & CASS Certification  U.S. NCOA  U.S. Pander Suppression  U.S. Prison Suppression Canadian Address Hygiene  Canadian Address Standardization & SERP Certification  Canadian NCOA  Canadian Pander Suppression  Canadian Prison Suppression International Address Hygiene  DSI WorldPlus International Hygiene  International NCOA  International Suppression (MPS/TPS/GAS)
