How to Submit Requests for Data


The request must be written and submitted via mail service, e-mail or fax to include:

  • contact person with telephone, fax, mailing address, e-mail address
  • type of data file and format required
  • payment in check or money order

Data export files are raw data files that can be manipulated using a spreadsheet or database program. The export is generally saved as ASCII text with headers in tab de-limited format. Dbase version 2 through 4 or Excel spreadsheet are examples of format options. Due to the large size of the files, it is necessary to compress (zip) the data when it is e-mailed. Compressed data includes an executable file that may be incompatible with some systems. The user must unzip the file prior to opening the file.

Users must know how to use the data file with their equipment. We provide general instructions, however, we do not offer technical support.

Please send your request with a check or money order for the applicable fee. Credit card payments are not available at this time.
