How to Write Consent Language for Your Web Form

Guide · 4 min read · Print this page

If your team calls or texts leads from a web form, the consent language on that form is one of the most important lines on your website. It decides who you may call, how, and with what tools. This guide explains what the rules generally require, offers sample language, and shows you how to keep records.

This is general information, not legal advice. Have a lawyer review your final language.

Why consent language matters

The Telephone Consumer Protection Act (TCPA) and FCC rules require prior express written consent for telemarketing calls that use an artificial or prerecorded voice. In February 2024, the FCC confirmed that AI-generated voices count as artificial voices. So if an AI agent will call your leads, your form needs language that clearly covers it.

What the rules look for

Under the FCC definition at 47 CFR 64.1200(f), prior express written consent is a written agreement that:

• Carries the person's signature. Electronic signatures under the E-SIGN Act count, which is why checkboxes and submit buttons can work.
• Clearly authorizes the seller to make telemarketing calls using an autodialer or an artificial or prerecorded voice.
• Covers the specific phone number the person provides.
• Discloses that agreeing is not a condition of buying anything.

Sample consent language

Here is an example for a fictional company. Adapt the company name, channels, and details to your business.

By checking this box, I agree that Brightline Roofing may call and text me at the phone number I entered about my request and related services, including calls and messages made with automated technology and AI-generated voices. I understand that consent is not required to make a purchase. Message and data rates may apply. I can opt out at any time by saying "stop" on a call or replying STOP to a text.

Why this works:

• It names one company, not "partners."
• It mentions calls, texts, automated technology, and AI voices.
• It ties the consent to the number entered.
• It says consent is not a condition of purchase.
• It explains how to opt out.

Where and how to place it

• Right above or next to the submit button. Do not hide it in a footer or behind a link.
• Readable size and color. Gray text on a gray background is a bad sign in a dispute.
• Unchecked checkbox. Many teams use a separate, unchecked box so the agreement is a clear action. Pre-checked boxes weaken your position.
• Optional, if you can. Letting people submit the form without agreeing to calls supports the "not a condition of purchase" statement.

What to avoid

• Long lists of partner companies. Consent should name who will actually call.
• Vague wording like "we may contact you."
• Burying it in terms of service. A link to a long document is not clear consent.
• Changing the language without tracking it. You need to know which version each lead saw.

Keep good records

If a consent question ever comes up, you will need proof. For each lead, save:

1. The exact consent text shown, with a version number.
2. Whether the box was checked.
3. Date and time of submission, with time zone.
4. The phone number entered.
5. The page URL.
6. The IP address and browser details.
7. A screenshot or archive of the form version.

Store these with the lead record in your CRM, and keep them as long as you may call the lead, plus a buffer your lawyer recommends.

Texting adds a few steps

If you text leads, your consent language should mention texts, and your message program should be registered for A2P 10DLC through your messaging provider. The opt-in method you describe in that registration should match what your form actually says. Reply STOP should always work.

Honor revocation

Consent can be taken back in any reasonable way, such as saying "stop calling me" or replying STOP. FCC rules require that revocation be honored within a reasonable time, not more than 10 business days. Make sure stop requests from calls, texts, and email all reach your do-not-call list.

Watch for rule changes

Consent rules change. In 2023 the FCC adopted a "one-to-one" consent rule for lead generators, and a federal appeals court vacated it in January 2025. State laws also add requirements. Set a reminder to review your form language with counsel at least once a year.

Quick checklist

• Names your company only
• Mentions calls, texts, automated technology, and AI voices
• Says consent is not a condition of purchase
• Explains how to opt out
• Sits next to the submit button in readable text
• Uses an unchecked checkbox
• Logs text version, timestamp, number, URL, and IP
• Reviewed by a lawyer

People who know what they signed up for are more likely to pick up when you call.
