Many organizations start with Congress Contact or the API and expand into Enterprise Licensing as their programs grow.
Other providers only assign districts at the ZIP or ZIP+4 level. Cicero offers that option but also matches at the individual address using precise district boundaries for the greatest possible accuracy.
Cicero manually verifies data as soon as an election is called and successively adds more data as it becomes available.
A dedicated team tracks out-of-cycle changes like resignations, appointments, special elections and ad-hoc redistricting so the data stays current.
BioGuide IDs, Open Civic Data IDs (OCD-IDs) and other identifiers 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.
