GOTV for Nonprofits: How to Run a Nonpartisan Voter Mobilization Program

The nonprofit organizations with the deepest community trust, food banks that know which families struggled last winter, health clinics where staff know patients by name, housing nonprofits that helped community members navigate the eviction moratorium, are among the least likely to run a nonprofit GOTV program.

Not because they oppose civic engagement. Most 501(c)(3) leaders believe that get-out-the-vote (GOTV) activity is legally off-limits for tax-exempt organizations. That belief is common. It’s also wrong.

Nonpartisan voter mobilization is explicitly permitted for 501(c)(3)s. The legal boundary is straightforward: No candidates, no parties, no partisan coordination. Nonpartisan voter mobilization means encouraging all eligible voters to participate regardless of who they vote for. Partisan campaign activity means directing outreach to benefit a specific candidate or party. Your organization can do the first. It cannot do the second.

This guide covers the legal framework, the list-building approach, and the outreach program execution so your organization can turn its existing community relationships into voter contacts when it matters most. If your organization is a 501(c)(4) or runs both issue advocacy and voter mobilization, CallHub’s guide to advocacy GOTV covers the additional legal lane and messaging considerations that apply.

What your 501c3 can and cannot do for voter mobilization

A 501(c)(3) organization can run voter registration drives, make nonpartisan phone and text banking calls, send Election Day reminders, and host candidate forums open to all candidates. What it cannot do is endorse, oppose, or coordinate with any candidate or political party in any way.

The authority for this comes from the Internal Revenue Code (26 U.S.C. § 501(c)(3)), which prohibits 501(c)(3) organizations from participating in or intervening in political campaigns on behalf of, or in opposition to, any candidate for public office. This is an absolute prohibition. It covers formal endorsements, social media posts that express candidate support or opposition, volunteer coordination with campaigns, and donation bundling.

The Johnson Amendment, the 1954 addition to Section 501(c)(3) of the tax code, is the legal shorthand most people reference. It has been in effect for over 70 years. The line it draws is clear: Issue advocacy is permitted; candidate advocacy is not.

The practical test is this: Does your outreach encourage all eligible voters to participate, regardless of who they vote for? If yes, it’s nonpartisan. If your outreach filters contacts by their likely candidate preference, or coordinates timing with a campaign, it crosses the line.

The National Council of Nonprofits provides guidance on how 501(c)(3)s can structure voter engagement programs within these legal boundaries.

Phone banking and text banking under 501c3 rules

Both phone banking and text banking are permitted for 501(c)(3) GOTV programs, with one additional compliance layer: The Telephone Consumer Protection Act (TCPA).

For calls and texts to your existing supporter base, TCPA exposure is generally low. Supporters who have provided their phone number and have an ongoing relationship with your organization typically fall within prior express consent requirements. When you reach contacts outside your existing list, such as from a matched voter file, consult legal counsel before proceeding on what consent requirements apply in your state.

Script compliance for calls is straightforward. Every call must:

• Identify the calling organization by name
• Frame the outreach as nonpartisan and not affiliated with any candidate or party
• Encourage voting without directing candidate preference
• Avoid evaluating any candidate by name

For text banking, peer-to-peer texting, where a volunteer sends messages to individual contacts one at a time rather than through an automated broadcast, carries a cleaner TCPA posture than bulk automated texts. Your existing phone banking for nonprofits guide covers the channel setup for both calling and texting programs.

How to build your nonprofit voter mobilization list

Your nonprofit already has the most valuable asset in voter mobilization: A community of supporters who trust your organization. Start with your existing contact database, not the voter file.

The voter file, the database of registered voters maintained by state and county election authorities, is where most GOTV programs begin. For nonprofits, that’s the wrong starting point. Your donors, volunteers, program participants, and newsletter subscribers are a community you’ve already earned. The relationship means your outreach is more likely to be received, responded to, and acted on.

The sequence to build your mobilizable contact list:

1. Pull your current contact database. Export name, address, and phone number for all active supporters. Clean duplicates and flag records with missing address data before moving forward.
2. Conduct a voter file match. Cross-reference your supporter list against the publicly available voter registration file for your geography. Organizations like Nonprofit VOTE provide free toolkits and state-by-state guidance for nonprofits running their first voter file match.
3. Segment by registration status. Supporters who are not yet registered become targets for your voter registration program. Those already registered go into your GOTV outreach queue.
4. Prioritize by voting history. If you have access to propensity scores through a voter data partner, prioritize sporadic voters. The marginal impact of GOTV outreach is highest for contacts with an inconsistent voting history.
5. Confirm contact consent. Before calling or texting, confirm you have the appropriate consent for each channel. Peer-to-peer texting to your existing opt-in list is generally the cleanest starting point.

Matching your existing supporters to the voter file

A voter file match cross-references your supporter database against registered voter records using name, address, and date of birth. Match rates depend heavily on the quality of your contact data. A clean, current list with complete address fields achieves significantly higher match rates than one with missing or inconsistent records.

If your supporter data is incomplete, your match rate will be low, and your outreach list will be thin. Invest in data hygiene before running the match: Standardize address formats, merge duplicates, and flag records missing phone numbers.

Some states allow 501(c)(3)s to access voter files directly for nonpartisan civic engagement purposes. Others restrict access to political committees. Check your state’s voter file access policy through your secretary of state office before requesting a file, and review the 501c3 political activity rules that apply to your organization before entering into any data sharing arrangement.

Running your GOTV outreach program

A nonprofit GOTV program running phone banking and text banking in parallel comes down to three things: Contact prioritization, script compliance, and volunteer management.

Phone banking produces measurable turnout lift. Research consistently shows that volunteer-led GOTV calls produce meaningful gains among contacted voters. The Analyst Institute’s meta-analysis of GOTV field experiments found that volunteer-conducted calls are approximately 2.1% more effective at turning out voters than calls made by paid or hired callers. The relationship your volunteers have to your community translates directly into outcomes.

What does that mean for your program? Prioritize volunteer outreach over hired callers wherever possible. Your volunteers represent the organization’s community ties. That’s what makes a GOTV call from your housing nonprofit different from a call from an unknown number. See CallHub’s guide to training GOTV volunteers for how to prepare them for these conversations.

When to use each channel:

• Phone banking: High-priority contacts, sporadic voters, community members with specific turnout barriers (transportation, polling place changes, ID requirements), and anyone who needs a real conversation
• Peer-to-peer texting (P2P texting): Broader list coverage, Election Day reminders, follow-ups after initial phone contact, and contacts who are more likely to respond to text than a call

Running both channels in parallel is standard for well-resourced nonprofit GOTV programs. The channels complement each other: Phone reaches depth, text reaches breadth.

“Predictive Dialing means that our callers are utilized at optimum capacity but not overwhelmed. Its ability to adjust in real time based on answer rate helps us provide a consistent experience as we reach thousands of contacts at scale,” says L, Operations Manager at a nonprofit that has mobilized over one million voters.

For organizations coordinating volunteers across both channels, CallHub for political and civic organizations handles contact deduplication, real-time data sync, and channel coordination so volunteers don’t reach the same contact twice through different channels.

What a compliant nonpartisan GOTV script looks like

A compliant 501(c)(3) GOTV script has three required elements: Organization identification, nonpartisan framing, and a specific ask.

A sample framework for phone banking:

Opening: “Hi, I’m [volunteer name] calling on behalf of [Organization Name]. We’re reaching out to community members to make sure everyone has the information they need to vote on [Election Day date].”

The ask: “We want to make sure you know when the polls are open and where your polling place is. Can I share that with you?”

Offer of assistance: “If you have any questions about how to get there, what ID to bring, or what to expect at the polls, we can help with that.”

Close: “Thanks for your time. We hope to see you at the polls.”

What the script does not include: Candidate names, party names, any framing that implies who to vote for, and any statement like “vote for the side that supports [issue]” that signals partisan preference.

For text banking scripts, the same principles apply. The message identifies the organization, offers information or assistance, and encourages participation without directing preference. Keep texts to two to three sentences with a clear offer to help. See CallHub’s GOTV text message templates for ready-to-adapt nonpartisan scripts.

Measuring your nonprofit GOTV program

Nonprofits often underinvest in GOTV measurement because the results feel intangible. They’re not. Your program produces concrete data you can report to funders, use to refine your next cycle, and use to identify which contacts responded to outreach.

Core metrics to track across your program:

• Contact rate: What percentage of outreach attempts reached a live person or received a text response?
• Confirmed voters: How many contacts confirmed they planned to vote or had already voted?
• Barrier flags: How many contacts raised a specific turnout barrier, such as transportation, polling place location, or ID requirements?
• Volunteer hours: Total hours spent on GOTV outreach divided by contacts reached gives you your cost-per-contact benchmark, which funders often ask for.
• Post-election voter file match: After Election Day, match your outreach list back against the updated public voter file to see what percentage of your contacts actually voted.

The post-election voter file match is your true outcome metric. It’s the most credible evidence of program impact for board members and funders. Plan your data retention before you start: You’ll need your contact list from outreach paired with your post-election outcomes file to run the match.

Make every community relationship count on Election Day

Your organization has already done the hardest part of voter mobilization. You’ve built trust with community members that political campaigns spend millions trying to replicate in the weeks before an election.

A compliant nonprofit GOTV program doesn’t require abandoning your mission or your nonpartisan identity. It requires applying the same organizing skills you already have, community outreach, volunteer coordination, and follow-through on barriers, to a specific window when your contacts can exercise the most direct influence over the policies that affect their lives.

Start with your existing supporters. Build the legal framework into your script from the first call. Keep the program nonpartisan at every step. Use the voter mobilization tools for your GOTV program that let your volunteers work at scale without burning out.
