Membership and district-office addresses are synced from Open States, which mirrors the Illinois legislature's own official roster. Representatives and senators are elected on different cycles in some states, so a seat can change hands between updates — confirm on the Illinois legislature's official site if you need certainty before a time-sensitive mailing.
