Other providers assign districts at the ZIP or ZIP+4 level. Cicero matches at the individual address using precise district boundaries – reducing errors when multiple districts exist inside the same ZIP+4.
Cicero monitors out-of-cycle changes and manually verifies data as soon as an election is called. You often receive accurate incoming-official contact data before other providers (including the USPS).
A dedicated team tracks resignations, appointments, special elections, and changes to contact information, websites, and social profiles so the data stays current.
BioGuide IDs and Open Civic Data IDs (OCD-IDs) make it easy to link Cicero records to other datasets and systems.
Whether you need a simple monthly contact file or a fully customized enterprise data feed, Melissa’s Cicero solutions give you the most reliable foundation for government relations, advocacy and civic engagement.
