Segmenting your database by ethnic origin is a successful targeting strategy employed by many direct marketers. With Cleanlist's Ethnicity Append service, it is easy and inexpensive to add ethnic origin to the names on your file with a precision you can count on.
Cleanlist maintains one of the world's largest and most accurate ethnic origin coding databases containing over 1 million surnames. The source data is licensed from one of North America's leading ethnic-based research firms and has been tested extensively by Cleanlist and our clients. You can count on the results being accurate and complete.
For each name on your list, Cleanlist will append both a primary and secondary ethnic origin. For example:
| European - Balkans | Croatia |
| Celtic - Celtic | Ireland |
| European - Eastern Europe | Russia |




Typically over 80%, depending on the accuracy and completeness of the input database.
Turn names and addresses into actionable customer intelligence with our Demographic Append bundle and, for even more personalized marketing campaigns, consider our Gender Append service.
