Always test your software with a "worst-case scenario" amount of sample data, to get an accurate sense of its performance in the real world.

These data files are of super high quality. See the description at the right. Included fields are:

• First Name
• Last Name
• Company
• Address
• City
• County
• State
• ZIP Code
• Phone
• Fax
• Email
• Web

All files are provided as CSV (comma-delimited).

Names are random, drawn from random first and last names in the US Census.

Addresses are real, and so should be useful for mapping, adddress validation, and other related purposes. United States only.

Company names are real, but are from a totally different part of the country than the address they are listed with.

Phone and fax numbers are random, but the area code and exchange for each are correct for their location.

Email and Web addresses are fake.

Each data file has unique records. The data in the smaller files is not contained within the larger files.

Records are in a totally random order and cover the geographic US with a more or less even distribution.
