Submitting confidential material to Wikileaks is safe and easy. We have several methods, but the best for most submitters is:

Wikileaks accepts classified, censored or otherwise restricted material of political, diplomatic or ethical significance. Wikileaks does not accept rumor, opinion or other kinds of first hand reporting or material that is already publicly available.

All staff who deal with sources are accredited journalists or lawyers. All submissions establish a journalist-source relationship. Online submissions are routed via Sweden and Belgium which have first rate journalist-source shield laws. Wikileaks records no source identifying information and there are a number of submission mechanisms available to deal with even the most sensitive national security information.

Wikileaks has a history breaking major stories (in the Guardian, New York Times, CNN, Reuters, etc), protecting sources (no source has ever been exposed) and press freedoms (all censorship attempts, from the Pentagon to London law firms have failed). Some examples:

If you want to send us a message of your own, as opposed to a document, please see Contact.


Submissions via secure upload

Fast, easy and automatically encrypted with the best banking-grade encryption. We keep no records as to where you uploaded from, your time zone, browser or even as to when your submission was made (if you choose a non-zero publishing delay, we set the file time record to be the release date + a random time within that day).

If you are anonymously submitting a Microsoft word file (".doc") that you have edited at some stage, please try to send a PDF document (".pdf") instead, as Word documents may include your name or the name of your computer, see Word file redaction for further information.

Medium risk submissions

You may want to use a computer that you are not associated with if your submission could result in the examination of your computer by people seeking the source. Your computer may keep a record of what websites you have visited and what files you have had on it. Even if you "delete" this information a skilled technician may be able to retrieve it.

If you use another computer (e.g at a netcafe, library); try not to use that computer for any other purpose that might identify you (e.g checking email).

High risk submissions

If you are of significant political or legal interest your internet connection maybe monitored by your ISP on behalf of government or others.

Additionally if you are submitting material of interest to the major intelligence agencies or their "friends" (defense contractors or allied agencies in other countries), please be aware that some of these agencies record internet traffic and may be particularly curious about traffic to and from our servers.

These groups may record that your computer has sent a lot of information to our computers, even if they cannot see what that information was due to encryption. See Connection Anonymity.

In these circumstances it is best to use a computer that can not be physically traced to you, however we also have technological means around this type of monitoring (which is called "traffic analysis").

The following method, In addition, provides military (as opposed to banking) grade encryption. It requires downloading and installing additional software. You may wish to submit from another computer or by post instead if you are not comfortable with installing and configuring new software.

You can also upload from a netcafe as in Medium risk submissions, but exercise reasonable diligence concerning witness.

For the highest levels of protection you may wish to use our postal submission network.

Submissions via email

Discreet Email

We accept email leaks upto 1000Mb in size however your email system may struggle with attachments this large. Gmail supports up to 20Mb.

We automatically discard all identifying information -- even your timezone and type of mail program. All emails received are encrypted with AES256 (approved for US military Top Secret communications) and stored on Wikileaks owned and controlled servers.

However your mail provider (e.g Yahoo/Gmail/Hotmail) may keep a record of the communication and where you logged in from. History has shown such records are divulged on government request[1] or commercial subpoena[2].

If this is a realistic risk for your communication to us, then create an email account not normally associated with your name. You may also wish to access this account from a computer unrelated to you.

If you have material of interest to major intelligence agencies or their allies you can email from a computer you don't normally use. Otherwise you may wish to use our Tor anonymizer.

Major spy agencies, such as the US National Security Agency or the Chinese Ministry of State Security (国家安全部) may intercept the communication if it flows past one of their listening posts (see Connection Anonymity).

Submissions via our discreet postal network

Submissions to our postal network offer the strongest form of anonymity and are good for bulk truth-telling.


  1. First place your leak onto a floppy disk, CD, DVD or a USB Flash Drive. If you are using a floppy disks, please create two as they are often unreliable. If you only have paper documents, we will scan them if they are of significant political or media interest (if you are unsure whether this may be the case, please contact us first).
  2. Post your information to one of our trusted truth facilitators listed below. You may post to whatever country you feel most suitable given the nature of the material and your postal service. If your country's mail system is unreliable, you may wish to send multiple copies, use DHL, FedEX or another postal courier service.

Wikileaks truth facilitators will then upload your submission using their fast internet connection. If you use a floppy disk, be sure to send two for increased reliability.

You can use whatever return address you like, but make doubly sure you have written the destination correctly as postal workers will not be able to return the envelope to you.

After receiving your postal submission our facilitators upload the data to Wikileaks and then destroy the mailed package.

High risk postal submissions

If your leak is extremely high risk, you may wish to post away from your local post office at a location that has no witnesses or video monitoring.

Many CD and DVD writers will include the serial number of the DVD or CD writer onto the CD/DVDs they write. If the post is intercepted this information can in theory be used to track down the manufacturer and with their co-operation, the distributor, the sales agent and so on. Consider whether there are financial records connecting you to the CD/DVD writer sale if your adversary is capable of intercepting your letter to us and has the will to do this type of expensive investigation.

Similarly, CD and DVD media themselves include a non-unique manufacturing "batch number" for each group of around 10,000 CD/DVDs made.

Although we are aware of no instances where the above has been successfully used to trace an individual, anti-piracy operations have used the information to trace piracy outfits who sell tens or hundreds of thousands of counterfeit CDs or DVDs.

If you suspect you are under physical surveillance give the letter to a trusted friend or relative to post. On some rare occasions, targets of substantial political surveillance have been followed to the post office and have had their posted mail seized covertly. In this rare case if you are not intending to encrypt the data and if the police or intelligence services in your country are equipped to perform DNA and/or fingerprint analysis you may wish to take the appropriate handling precautions.

Postal addresses of our trusted truth facilitators

You may post to any country in our network. Pick one that best suits your circumstances. If the country you are residing in has a postal system that is unreliable or frequently censored, you may wish to send your material to multiple addresses concurrently. For unlisted addresses postal addresses, please contact us.
