Step 1 - Visit https://www.locatepeople.org/ and run a search for your name.

Step 2 - Scroll down until you find your record. Once you have found your record you will want to copy your report ID, which you can see in this example.

Step 3 - Next, go to LocatePeople’s opt-out page https://www.locatepeople.org/optout/. Or scroll down to the bottom of the homepage and click the Do Not Sell My Information link on the footer.
Please note: Whenever you remove your information from a true people search website, you may want to use a disposable email such as TempMail so that you don't expose your email.
Step 4 - Fill out your first and last name, paste your Record ID number, and enter your email address. Solve the CAPTCHA box, and then click the Submit button.

Step 5 - Find the verification link in your inbox and click confirm to finalize your opt-out.
