How to Send Tips to ProPublica

Our job is to hold people and institutions accountable. And it requires evidence. Documents are a crucial part of that. We are always on the lookout for them — especially, now.

Have you seen something that troubles you or that you think should be a story? Do you have a tip about something we should be investigating? Do you have documents or other materials that we should see? We want to hear from you.

Below are a few ways to contact us send us documents and other materials, safely, securely and anonymously as possible.

  1. Signal: +1-347-244-2134
  2. WhatsApp: +1-347-244-2134
  3. Email: [email protected]
  4. Postal Mail: 155 Ave of the Americas, Floor 13, New York, NY 10013-1507
  5. Our Staff List:


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 is: +1-347-244-2134

If you’re concerned about someone knowing you are contacting ProPublica, we suggest that you enter in 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. So in some situations, it might even be better to use a separate phone for Signal communications.


WhatsApp is a popular messaging app owned by Facebook, which also provides end-to-end encrypted communications. Although the message contents are encrypted, the WhatsApp service may retain some metadata about who you are communicating with and when.

Our WhatsApp number is: +1-347-244-2134

Messaging us on WhatsApp may be preferable if you already use WhatsApp and don’t want to install another app on your phone. As with Signal, your phone number will be revealed to ProPublica, so you may want to consider other options (or use a separate phone) if you are concerned about that.


Our general tips address is [email protected].

To contact specific reporters, see our staff list. Many of our reporters have their own Signal numbers listed, and some reporters also use PGP (aka “GPG”) for email encryption as noted on their profiles.

Although plain email is convenient, if your information is sensitive we recommend contacting us using the other options first.

If you decide to use PGP, we also note that PGP, like a mailing envelope, only encrypts your message content and not the “to”, “from”, or subject line of your emails. You may also consider registering a new, anonymous email address in combination with PGP.

Postal Mail

Postal mail is an excellent, easy way to reach ProPublica 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:

155 Avenue of the Americas
13th Floor
New York, NY 10013-1507

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.
