Our general tips address at ProPublica Illinois is email@example.com.
To contact specific reporters, see our staff list. Many of our reporters have their own Signal numbers listed.
Although plain email is convenient, if your information is sensitive we recommend contacting us using the other options first.
Signal is a free messaging app for iPhone and Android that provides end-to-end encryption for messages and calls. Signal does not collect any metadata regarding who you are messaging: the service only retains your phone number and the last time you accessed the app.
Our Signal number for Illinois is currently unavailable. Please send Signal messages through our national office.
If you’re concerned about someone knowing you are contacting ProPublica Illinois, we suggest that you enter our Signal number (or any reporter’s Signal number) directly in the app and not add it to your address book.
Also: Messaging us on Signal does reveal your phone number to ProPublica Illinois. So in some situations, it might even be better to use a separate phone for Signal communications.
Postal mail is an excellent, easy way to reach ProPublica Illinois securely. U.S. postal mail without a return address is one of the most secure ways to communicate — authorities would need a warrant to intercept and open it in transit.
Don’t use your company or agency mailroom to send something to us. Mail your package or envelope from an unfamiliar sidewalk box instead of going to a post office. You can mail us paper materials or digital files on, for example, a thumb drive. Our mailing address is:
211 West Wacker Drive
Chicago, IL 60606
If you can identify a reporter you want to reach, it’s worth noting that inside your package or envelope. You can also simply address it to ProPublica Illinois.
