Change.org vs. other petition platforms: How to choose the right one

There's more than one place to start a petition online. Change.org, Petitions.com, iPetitions, GoPetition, Care2, and Avaaz are all platforms where you can collect signatures for a cause. The real question isn't which is "best" in the abstract. It's which one fits what you're actually trying to achieve.

This guide walks through how to choose the right tool for your needs. Discover the breakdown of exactly how the major platforms compare on the things that matter most: how many people will see your petition, what happens after someone signs, what it costs, and what happens to your data and your supporters' data.

How to choose the right petition platform

If you're an individual with a personal cause, you want reach above almost everything else. Your petition needs to find people who don't already know you or your issue exists. And not just anyone, but people who care about the same issues as you and who are already engaged with advocacy campaigns, like the Change.org community. This is where platform size and search visibility matter most.

If you're a nonprofit running a campaign, you want a platform that can turn signatures into supporter relationships you can build on. Look at what data you get access to, whether the platform documents that access honestly, and whether it plays well with the other tools in your stack.

If you're pushing for policy change, you want decision-maker infrastructure. Not just the ability to collect signatures, but built-in ways to prove the support is real and put it in front of the person who can act on it.

If you're organizing your community, you want a platform that helps you find and mobilize people who are close to the issue, not just people who happen to see it online. Geographic tools and constituent proof matter more here than raw signature counts.

Most causes and campaigns intersect with more than one of these cases. The comparison below is built around the factors that actually move each of these goals forward, not just a platform feature checklist.

Platform comparison

Figures reflect publicly available information as of this writing. Petition platforms update their features and terms regularly, so it's worth checking each platform directly for the latest details.

What each platform actually offers

Change.org reaches 589M+ active users currently and collects 500,000+ signatures daily. It has driven 105,000+ documented petition victories. Automatic notifications are sent to decision-maker at 10 signatures, and petitions surface a public constituent count with ZIP-level geographic proof once a petition reaches 100 signatures with 60%+ geographic concentration. Qualifying local petitions may also get direct outreach from Change.org's Civic Engagement Team.

An AI-assisted creation flow helps starters draft and launch. It's free to start and sign; chip-in prompts and promoted petitions are optional and never required. Change.org is a public benefit corporation that doesn't sell signer data. Starters get name, country, postal code, date, and comments from signers; email addresses aren't exported, and signers can opt out of displaying their name.

Petitions.com reports reach figures that aren't independently verified, and doesn't publish a running total of petition wins. Delivery to decision-makers is manual. It states it doesn't sell data and is built around GDPR-style consent choices.

iPetitions has collected 50M+ signatures since 1999. It doesn't publish a victories total. Signer lists are downloadable for manual delivery, there's no automated decision-maker notification, and there's no premium tier. It includes an AI writing assistant ("Co-pilot") to help draft a petition. It states a neutral, non-endorsing position and is funded by advertising and donation prompts rather than signer data sales.

GoPetition hosts 80,000+ petitions and reports roughly 40 million monthly site visits. It doesn't publish a victories total. Its signature map shows geographic clustering, but there's no automated decision-maker notification. Its premium tier explicitly includes exporting signer emails for the petition author's own use.

Care2 reports more than 65 million members and 400,000+ petitions created. It doesn't publish a running total of wins. There's no built-in decision-maker notification tool. Nonprofits typically pay Care2 as a cost-per-acquisition vendor, reported at $2–2.50 per signer contact. Care2's own privacy policy discloses that it has sold or shared personal information for a business purpose within the past 12 months. Signer name, city, state, country, and comments are public by default unless the signer selects otherwise.

Avaaz reports 69M+ members (self-reported) and 609M+ cumulative actions taken across all campaigns. Notable wins are documented individually rather than as a running total. Campaigns are largely staff-curated rather than self-serve, so there's no independent decision-maker notification tool for individual signers.

It's free to sign and funded entirely by member donations, with no corporate, government, or foundation funding accepted. Avaaz is a nonprofit (Avaaz Foundation) that states it does not rent or sell personal information; it shares signer name, city, country, and comments with campaign targets, full address or postal code only if the target requires it, and uses hashed member data for Facebook ad-audience matching.

What actually sets Change.org apart

There are three important outliers to consider about Change.org when comparing petition platforms:

Scale that isn't just a number. Reach matters because it's the difference between a petition that sits unseen and one that finds the people who care. Change.org's search visibility opens at 5 signatures, meaning a petition starts showing up in relevant on-platform searches almost immediately, not after it's already gone viral somewhere else.

Decision-maker infrastructure that runs in the background. Most petition platforms stop at "collect signatures and download the list." Change.org's threshold system does more of the work automatically: notifying a named decision-maker at 10 signatures, surfacing a public constituent count once a petition hits 100 signatures with strong geographic concentration, and in some cases triggering direct outreach from Change.org's own Civic Engagement Team to local officials. Read more in the guide to engaging decision-makers.

A business model that doesn't depend on selling supporter data. Some petition platforms make their money by generating and selling signer contact information to client organizations. Change.org's chip-in prompts and promoted petitions are optional and don't affect who sees a petition or how signatures are counted. Learn more about how promoted petitions work.

Proof in practice

These petition victories demonstrate how Change.org’s petition creation and growth tools, decision maker support, and reach produce campaigns that solve problems and result in concrete, positive outcomes.

A local ordinance, reversed. When Phoenix considered an ordinance that would have restricted a volunteer feeding ministry's ability to serve people experiencing homelessness in public parks, the group behind it launched a petition targeting the mayor and city council. The petition crossed 1,000 signatures, triggered outreach from Change.org's Civic Engagement Team, and led to a documented public response from a council member's office ahead of the vote. 

A federal grant, secured. A petition to protect endangered red wolves from highway deaths, naming three specific government agencies, ran alongside a coalition campaign and helped drive $25 million in federal grant funding for wildlife crossings.

A national database, stopped. A parent's petition to stop a proposed national registry of autistic individuals gathered 50,000 signatures, drew media coverage from The Guardian, and contributed to the U.S. Department of Health and Human Services canceling its plans for the registry.

Each of these campaigns used the same underlying mechanics: a named decision-maker, a documented base of public support including personal comments from signers, and a platform built to make that support visible to the people who could act on it.

Frequently asked questions

Is Change.org free? Yes. Starting a petition, collecting signatures, and sharing your campaign are all free. Chip-in prompts and promoted petitions are optional ways to support the platform or increase a petition's visibility, but neither is required to run a successful campaign.

Which petition site has the most users? Change.org has more than 577 million active users, making it the largest petition platform by that measure. Other platforms report smaller or less consistently verified membership numbers.

Can I export my signatures? Yes. Petition starters on Change.org can access and export signer names, general location (country and postal code), signature date, and any comments left. Signer email addresses are not included in exports, which is different from some other platforms that make signer emails downloadable.
