List and File Types

Mail Files
PDI mail files are designed specifically for direct mail use. We group all individuals in a household together to avoid sending multiple pieces of mail to the same house. Each mail file record includes fields for name, address, and house salutation. We run all mail file data through National Change of Address (NCOA) data, removing any known bad mailing addresses.

Printable Walk/Phone Lists
Phone and Walk lists are designed to be printed from a PDF file. Walk lists are grouped and sorted for door-to-door canvassing. Phone lists are grouped and sorted for phone canvassing. Lists include name, address, phone numbers, party, age, gender, vote history, and overlapping districts. Lists can also be customized with response codes, surveys, and optional sub-universes.

Phone Files
Our phone files have been optimized for immediate use by professional telemarketing firms doing live calling or in other texting or dialing programs. Landlines Phone Files group voters with the same landline phone number and include a mix of household and individual data elements, while Cell/mobile phone have each cell phone number associated with only one voter.

Polling Samples
Polling samples are available using random or stratified sampling techniques to ensure they accurately represent your target audience. Clients provide the sample geography, demographic universe, number of requested interviews, and sampling method. Contact a PDI data expert to place your order or learn more.
