What is Wikipedia?
Wikipedia is the largest collection of free, collaborative knowledge in human history. Millions of people from around the world have written and added to Wikipedia since it was created in 2001: anyone can edit it, at any time. Wikipedia contains more than 40 million volunteer-authored articles in nearly 300 languages. It is viewed more than 15 billion times every month, making it one of the most popular sites in the world. Wikipedia means something a little different to everyone -- but the people who support it are united by their curiosity, joy of knowledge, and belief in the fact that we can know much more together than any of us can alone.
What is the Wikimedia Foundation?
The Wikimedia Foundation is the non-profit organization that supports and operates Wikipedia and the other free knowledge projects. All of our work is guided by our mission to share the sum of all knowledge with every person in the world. We keep the websites fast, secure, and available. We support the community of volunteers who contribute to the Wikimedia projects. We make free knowledge accessible wherever you are — on your phone or laptop, on a boat in the South Pacific, or in the hills of Nepal. We help bring new knowledge online, lower barriers to access, and make it easier for everyone to share what they know.
The Wikimedia Foundation is a 501(c)(3) tax-exempt non-profit organization with offices in San Francisco, California, USA. You can also review our letter of tax-exemption and our financial reports and annual filings.

If I donate to the Wikimedia Foundation, where does my money go?
Donations to the Wikimedia Foundation help sustain free knowledge through Wikipedia and its sister projects for people around the world. Your contributions pay for technology to keep the sites fast, secure, and accessible, for Wikimedia programs and initiatives to expand access and support free knowledge globally, and grants to volunteer contributors to improve and enrich the knowledge on the sites.
Why should I donate?
Wikipedia relies on donations from people around the world. Contributions to the Wikimedia Foundation keep Wikipedia accessible, growing, and improving.
Where can I find more financial information?
The Wikimedia Foundation 2014–15 annual report covers the fiscal year from July 1, 2014, to June 30, 2015. The Foundation's annual report shares some of the voices of the tens of thousands of people who make the Wikimedia movement possible.

How is the Wikimedia Foundation run?
There are roughly 280 staff and contractors at the Wikimedia Foundation, led by Executive Director Katherine Maher.

How is the Wikimedia Foundation funded?
The Wikimedia Foundation is funded primarily through

Why doesn't Wikipedia use ads for revenue?
We are not considering advertising as a source of revenue. We do not believe that advertising belongs in a project devoted to free, reliable, and neutral knowledge. Introducing commercial interests could jeopardize Wikipedia’s reliability as a neutral source of information. Our global volunteer community has always felt that advertising would have a major effect on our ability to stay neutral, and ultimately ads would weaken readers' overall confidence in the articles they read on Wikipedia.
We are not against the world of online advertising, nor are we against other organizations that host ads. We just know ads are not appropriate in a project devoted to education and knowledge – and especially one that strives for balance and neutrality.
What are your plans? Where is this going?
The Wikimedia Foundation’s vision asks us to Imagine a world in which every single human being can freely share in the sum of all knowledge. We're serious about this vision. We aspire to not only reach everyone, anywhere in the world, but to include new and diverse voices on Wikipedia. These are some of the activities we're focused on right now:
Operating one the world's largest web properties. At its heart, the Wikimedia Foundation requires operational excellence to continue to keep Wikipedia online and thriving. Our aim is to provide the best possible site experience to everyone in the world, to maximize uptime, and to ensure that all the information in Wikimedia projects is safe and secure.

Providing access to Wikipedia everywhere. We need to make sure that our sites and services support a multi-platform experience, including on mobile. Our work with the Wikipedia Zero program, the program aimed at providing free access to Wikipedia on mobile devices in the Global South, is one of the ways we’re expanding Wikipedia’s reach across the globe.This work is just a start, and we’re constantly looking for new ways to reach more people in more parts of the world.

Creating new tools for editors. Our goal is to make it as easy as possible to contribute knowledge, and to give volunteers and readers great tools for assessing and improving article quality. For example, one of our latest tools, the Content Translation Tool, has been used to translate more than 30,000 new articles on Wikipedia.

Supporting outreach and community initiatives worldwide. With the Wikimedia community, we support and develop a variety of events, initiatives, and outreach campaigns around the world. Some are targeted at bringing in new volunteers; some give the community space to reflect and further improve their work. Recognizing the value of people coming together because they are passionate about Wikimedia's mission has been key to our success.

Informing our decision-making with facts and data. The Wikimedia Foundation Statistics Portal provides a wealth of up-to-date research that helps us understand the impact of our work. Research projects provide us with in-depth analysis and experiments, supported by the volunteer-driven Research Committee. Analytics, research, experiments, and forecasts are essential to make good decisions in a complex environment like Wikimedia.

Are you associated with WikiLeaks?
No. The Wikimedia Foundation and Wikipedia have no affiliation with WikiLeaks. Although both use the term "wiki" in their name, they have always been completely separate and unaffiliated.
The word “wiki” refers to a website built using collaborative editing software. Hundreds of organizations and projects also use the term with no affiliation to Wikipedia or the Wikimedia Foundation, including wikiHow and WikiEducator.
Wikipedia and the Wikimedia Foundation’s history predates and is independent from WikiLeaks. Wikipedia was founded in January 2001 by Jimmy Wales, while WikiLeaks was founded in October 2006 by Julian Assange. Wikipedia is developed by thousands of volunteers from around the world with support from the United States based nonprofit organization Wikimedia Foundation.
How will you use the funds if donations exceed the goal?
We recently reached our $25 million December goal! We are overwhelmed and grateful for this support. Additional funds raised in December will help accelerate our work and enable us to embark on some important new projects. The work includes improving Wikimedia Commons and Wikidata, both of which power parts of Wikipedia; adding another caching center to our servers to make Wikipedia faster for more users, increasing support for projects to improve community health, funding strategic research and consultation, and investing in an independent endowment (which is separate from the Wikimedia Foundation) to protect Wikipedia for the future.
How can I donate via debit or credit card?
To donate using any major credit or debit card (VISA, MasterCard, Discover or American Express), PayPal, bank transfer, Amazon, and many other methods; please visit our Ways to Give page. Our donation options support many (although not all) currencies.
What other options exist to allow me to donate?
Alternative ways to donate to the Wikimedia Foundation include:
Why does the Wikimedia Foundation accept Bitcoin?
The Wikimedia Foundation, as a donor-driven organization, has a fiduciary duty to be responsible and prudent with its money, while striving to provide as many methods of donating as possible. Our donors indicated that they were interested in supporting us through Bitcoin, so after some initial research, we set up a method to accept those donations. You can also read our blog post for more information about donating via Bitcoin.
Are my donations tax-deductible?
Please refer to the information on tax-deductibility for the details of tax-deductions and tax receipts.
Why is there a minimum donation?
Our donations range widely in size, and we try to offer as low a minimum as possible. The minimum donation is helpful in deterring unauthorized uses of financial information.
What is your refund policy?
If for any reason you wish to have your donation refunded, please contact us via email at donatewikimedia.org. We will need the following information in order to process your refund:
- Date of donation (All refund requests must be made within 90 days of donation)
- Amount donated (Donations above USD $10,000 are considered major donations and are subject to the applicable grant agreement between the Foundation and the donor)
- Full name
- Payment method used (credit card, PayPal, check etc.-- please do not include credit card numbers in your email)
- Country of origin
- Reason for the refund
Please note that some payment methods may not support refunds, or require refunds to be made through the payment method (card) utilized, so additional information may be required to process your refund. All refunds will be processed as quickly as possible, but processing times may vary depending on the payment method.
We can only refund Bitcoin donations in Bitcoin. Because we do not store Bitcoins, refunds will be calculated based on the U.S. Dollar amount we received via instant exchange at the time of the donation, using our payment processor's Bitcoin sell rate when the refund is issued. The Wikimedia Foundation is not responsible for any change in value based on fluctuating exchange rates.
What can I do to help you spread the word of Wikipedia?
Spread the word any way you can! Tell your friends, family, and peers what Wikipedia means to you. Ask them if they use it and if so, what it means to them. You can also connect with our social media channels below and share Wikimedia stories with your network.
