Illinois elects 17 members of the U.S. House of Representatives. A congressional district is redrawn after each census to hold equal population, so it follows neither county lines nor city limits, and an address a mile away can sit in a different one.

What the lookup shows
Select any point and the card names the district number covering it and the representative who holds the seat, with their party, their Washington and district offices, and a link to their House page.
Your U.S. senators are not here, and that is not an omission: senators are elected statewide, so every address in the state has the same two and no map can tell them apart.
District, county and ZIP are three different shapes
A congressional district is an electoral boundary and nothing else. It splits counties, it splits cities, and it splits ZIP codes — which is why a ZIP-code lookup can return two representatives and be right both times. The map answers for one exact point instead.
Where the names come from
The boundaries come from the Census Bureau's own published districts and the roster is re-read on a schedule from the House's member list, landing as a reviewed pull request. The map names no officeholder it cannot cite.
Who represents each Illinois congressional district
All 17 seats on Illinois's delegation to the U.S. House of Representatives, as this site had them on September 11, 2026. The map above reads the same roster, so a card and this table cannot disagree — but a table is a claim about a day, and this one names its day. Where the roster names nobody it says so rather than guessing. Where these names come from.
