IDFPR Illinois License Lookup - Roofing Contractors & Firms

IDFPR Illinois License Lookup: roofing contractors, design firms and licensed businesses

Illinois licensed businesses from the official IDFPR license database, as a spreadsheet. Licensed roofing contractors, architecture and engineering design firms, home inspection companies, alarm/security/locksmith agencies, real estate brokerages, CPA firms, HOA management firms and more. Each row has the business name, IDFPR license number, license type, status, original issue and expiration dates, discipline flag, city, county and ZIP.

Sample output (real rows, a few of the columns):

More than 50,000 active business licenses across 16 IDFPR business categories, with 5,000+ licensed roofing contractors and 3,900+ design firms. Hundreds of new business licenses are issued every month. Use it three ways:

1. New-license leads. Set issuedWithinDays (for example 30) to get every business IDFPR licensed in that window, newest first. Schedule it weekly for a fresh feed of new Illinois roofing contractors or design firms.
2. Full Illinois license list. Leave issuedWithinDays at 0 and pick categories, counties, cities or ZIP prefixes to export the full active list for a territory.
3. Bulk IDFPR license lookup / verification. Paste license numbers into licenseNumbers to check status, expiration date and discipline for a whole subcontractor or vendor list in one run.

Free to try: Apify's free plan ($5/month in credit, no card needed) covers about 1,600 records a month. Price: $3.00 per 1,000 results.

RUN_SUMMARY in the key-value store shows rows scanned, results, rows dropped by the privacy filter, and the not-found list for license lookups.

Who uses this

• Roofing suppliers, distributors and equipment dealers prospecting newly licensed Illinois roofing contractors.
• Insurance, surety and bonding agents (roofing contractors need a bond and liability insurance to get licensed).
• Software and service vendors selling to architecture/engineering firms, real estate brokerages, HOA managers or home inspectors.
• General contractors, property managers and marketplaces verifying roofing and design-firm licenses in bulk.

Privacy by design

• Business licenses only. Only records IDFPR flags as business licenses are read. Any business row that still carries a person's first or last name is dropped (about 0.5% of rows).
• No individual licensees and no personal-name columns are ever requested from the API.
• No free-text discipline narratives. Only the case number, action type and dates.

Common questions

Is this data legal to use? Yes. It is official State of Illinois open data published by IDFPR on data.illinois.gov. Under the Illinois Open Data Act (20 ILCS 45) public data sets are in the public domain and free to reuse. Results are lightly reformatted (dates as YYYY-MM-DD, names of cities and counties title-cased); every row links to the source dataset.

How fresh is it? IDFPR updates its bulk license data weekly; the single-license lookup on the IDFPR site updates daily. Each run queries the dataset live and every row has retrievedAt.

How do I verify an Illinois roofing contractor license? Paste the license number into licenseNumbers (or the company name into keywords with activeOnly off). You get status, expiration date and discipline. Confirm on the official IDFPR license lookup (verifyUrl) before you hire.

How much does it cost? Free to try with Apify's free plan ($5/month credit, no credit card), which covers about 1,600 records a month. After that it is $3.00 per 1,000 results, plus a fraction of a cent per run.

Can I get new licenses automatically every week? Yes. Save your filters as a task and add a weekly Schedule with issuedWithinDays: 7. Send each batch to Google Sheets, Slack, email, Zapier, Make or n8n under Integrations.

Can I call it from code or an AI agent? Yes. Use the Apify API or the Python/JavaScript clients, or connect it to Claude, ChatGPT or Cursor through the Apify MCP server.
