Chicago

481 businesses listed, showing 1–40. How we order them.

Chicago's IT company listings cluster hard around downtown. Zip 60606 alone holds 77 of the 481 entries, with another 53 in 60654 and 24 in 60611 — so browsing by zip actually narrows things fast if you're looking near the Loop or River North versus a further-out neighborhood.

Most of these 481 listings come with real contact info: 465 have a phone number and 462 have a website listed. None of these listings carry a Sponsored badge in this category yet, since paid placement hasn't been switched on here, so what you're looking at is just directory order, not a paid or ranked lineup. If you run one of these companies and find a stale number or a broken site link, you can claim the listing yourself and fix it, which saves the next person a wasted call. Worth calling two or three in your zip before picking one.
