Open the form and say who you are
Go to the FastPeopleSearch opt-out form. The first field is a dropdown labeled "I am:" with two choices: the subject of this request, or an authorized agent of the subject. If this is your own listing, pick subject, because picking agent opens three more fields for the agent's first name, last name and email.
Do this by hand, in a real browser. The site sits behind Cloudflare bot protection and the form carries a Cloudflare captcha, so there's no scripted, bulk or automated path through it. If you'd rather skip the form, their Do Not Sell notice publishes a phone line at (866) 679-8725.
Give them a name and an email, and stop there
First Name, Last Name and Email address are required, and Middle Name is optional. That's the entire first form. It doesn't ask where you live, what your number is, or which page has your listing on it, so don't go hunting for any of that yet.
Tick the authorization box underneath, which certifies you're the subject or an authorized agent, then complete the captcha and click SUBMIT. Use an email address you actually check. Everything from here happens in your inbox, and nothing on their side will chase you.
Click the emailed link the same day
Their page promises the email, then hedges on when: it may take some time to arrive. Check your spam folder if it hasn't landed, because a filtered message is a silent failure here, and there's no status page to tell you.
The link is dead after 24 hours. Their wording: if you wait more than 24 hours to click it, you'll need to request a new one. There's no grace period and no resend button on the page. Open a link on day two and you've lost the first step all over again, captcha included.
Make the second form match the record
The link opens the real opt-out form, and this is the step where your record actually gets identified. Their instruction is that what you enter should match the information on the record you want removed, so open your listing in another tab and copy what it shows, including the middle name and the old address if that's what's on the page.
They put the warning on the opt-out page in writing: omitting information or providing inaccurate information will only hinder the opt-out process. Under-fill the form to avoid handing over more than you have to, and they treat that as your mistake, not theirs. So fill it out completely.
Submitting lands you on a confirmation page and sends a confirmation email, and their stated window is the only timeline they publish anywhere: allow 3 days for your record to be fully removed from the site. Keep that email. It's the only receipt you get.
Check on day four, then keep checking
Search your name again on the fourth day and click through to the listing itself, not just the Google result. A search result can outlast the page behind it, and the page coming down is the part they control.
It won't stay down, and they tell you that up front. Their notice says they regularly receive new public records, so even after you opt out your information may appear in their data products again, and they recommend you periodically refresh your opt-out request. There's no permanent suppression list on offer and no case number to quote, so re-checking on a schedule is the whole maintenance plan.
If you want it deleted, that's a different form
Deletion, access and correction live at their Privacy Rights page, under the topic "I want to access, delete, or correct my personal information." It's a much heavier form. It wants street address, city, state, zip and phone number, plus optional date of birth and listing URL, and it has its own captcha. You're handing over more than the opt-out asked for, to a site that collected your information without asking you first, and that page also lists a different phone number, (866) 933-3584.
They identify you by comparing what you type against what they hold. Their stated method is to match two or three of the data points you provide, and authorized agents may be asked for signed authorization, and they keep the right to make you verify directly regardless.
None of it reaches the original source. Their own notice says the opt-out won't remove the data from where it came from, so your information may still appear on other websites or through other services. They also argue that publicly available information isn't covered by state privacy laws and that they apply your request to it as a courtesy. Read that as goodwill they can withdraw. By its own footer, FastPeopleSearch isn't a consumer reporting agency under the FCRA either, so the dispute and accuracy rights that work on background-check companies don't attach here.
