Whether you're a nonprofit, advocacy group, or political organization, accurate Congressional data is essential for targeted, compliant mailings. We make sure your file reflects today's Congress — not last month's.

What we append
Every append type is maintained in-house and updated on a continuous basis — no third-party data resellers.
Congressional District Numbers
Append the correct Congressional District number to every record based on the donor's address. Updated whenever redistricting occurs.
House of Representatives Names
Append the current U.S. Representative name for each record's district. Updated daily to reflect elections, resignations, and special elections.
Senate Names (Senior and Junior)
Append both the Senior and Junior U.S. Senator names for each record's state. Kept current with every change in Senate composition.
Governor Appends
Append the current Governor name for each record's state. Ideal for state-level advocacy and issue-based direct mail campaigns.
Redistricting Updates
As Congressional districts are redrawn following the census or court orders, we update our district boundary data so your appends remain accurate.
Standalone or Bundled
Congressional appends can be ordered as a standalone service or included as part of our full-service direct mail data management and Merge/Purge processing.
Congress changes. Your data should too.
Elections, resignations, redistricting, and special elections happen throughout the year. Southern Solutions monitors every change so your file stays accurate without any extra effort on your part.
