Sync.ME is a popular caller ID and spam-blocking app that maintains a massive database of phone numbers linked to names, photos, and social media profiles. If you've never installed the app yourself, your information may still be in their system — uploaded by someone else who has your number in their contacts. This guide walks you through the official Sync.ME opt-out process to remove your phone number and personal data from their service.
What Information Does Sync.ME Collect?
Sync.ME builds its caller ID database by crowdsourcing contact information from its users' address books. When someone installs the app and grants contact access, every name and number in their phone is uploaded to Sync.ME's servers. A typical Sync.ME profile can include:
- Your full name as stored in other people's contacts
- Your phone number (mobile, home, or work)
- Your photo (pulled from social media or contact photos)
- Your location or area code information
- Links to associated social media profiles
This means your information can appear in Sync.ME's database even if you've never used the app, simply because a friend, colleague, or acquaintance uploaded their contacts. To understand the broader ecosystem, see how data brokers get your information.
Why You Should Opt Out of Sync.ME
Having your phone number linked to your real name in a publicly queryable database creates several risks:
- Reverse lookups expose your identity. Anyone with your phone number can discover your full name, making it easy to cross-reference other data broker sites for your address, relatives, and more.
- Social engineering attacks. Scammers use caller ID databases to personalize phishing calls, greeting you by name to build false trust.
- Stalking and harassment. An unwanted contact who only has your number can instantly learn your real name and begin locating you across other platforms.
- Privacy erosion. Your phone number was meant for people you chose to share it with — not a global directory anyone can search.
How to Opt Out of Sync.ME (Step by Step)
- Go to the opt-out page. Visit sync.me/unsubscribe/ in your browser. This is the official removal page.
- Enter your phone number. Type your full phone number, including the country code (e.g., +1 for the United States).
- Provide your name and email. Fill in the name and email address fields as requested on the form.
- Complete the CAPTCHA. Check the "I'm not a robot" reCAPTCHA box to verify you're a real person.
- Submit your request. Click the "Submit" or "Unsubscribe" button to send your removal request.
How long does removal take?
Sync.ME typically processes opt-out requests within 24 hours. After that, your phone number and associated information should no longer appear in their caller ID results.

One opt-out won't stop them — brokers relist your data. PrivacyOn removes your info from 100+ sites and keeps it removed.
Start your free scanWhat If Your Information Reappears?
Because Sync.ME continuously receives new contact uploads from its users, your information can resurface after a successful opt-out. If a new user uploads their contacts and your number is in their address book, Sync.ME may re-add you to their database. You'll need to repeat the opt-out process periodically — checking every two to three months is a reasonable cadence.
Check under multiple numbers
If you have more than one phone number (work, personal, old numbers you still own), search and opt out of each separately. Sync.ME treats each number as a distinct entry.
Additional Steps to Protect Your Phone Number

Frequently Asked Questions
Is the Sync.ME opt-out free?
Yes. The opt-out process through sync.me/unsubscribe/ is completely free and does not require creating an account or downloading the app.
Do I need to have the Sync.ME app installed to opt out?
No. You can submit an opt-out request through the website without ever installing the app. In fact, most people who need to opt out have never used Sync.ME themselves.
Can I find out who uploaded my information?
