NumLookup is a reverse phone number lookup service that allows anyone to search a phone number and find the owner's name, address, and other personal details. The site claims to have data on nearly every registered consumer and business in the United States. If your phone number is in their database — and it very likely is — here's how to get it removed.
What Information Does NumLookup Collect?
NumLookup aggregates data from public records, telecommunications databases, and third-party data providers to build profiles linked to phone numbers. A typical lookup result may include:
- Full name of the phone number owner
- Current and past home addresses
- Phone carrier and line type (mobile, landline, VoIP)
- Email addresses associated with the number
- Age and date of birth
- Names of relatives and associates
- Social media accounts linked to the phone number
This kind of information in the wrong hands can lead to real problems — from spam calls and phishing attacks to stalking and identity theft. Anyone who knows your phone number can use NumLookup to find out where you live and who you're connected to.
Step-by-Step Opt-Out Process
-
Go to the NumLookup opt-out page:
Visit numlookup.com/opt_out in your browser. This is the site's official removal page.
-
Enter your phone number:
Type in the phone number you want removed from their database. Use the full 10-digit number including area code.
-
Complete the CAPTCHA:
Solve the CAPTCHA verification to prove you're a real person, not a bot.
-
Click "Remove My Info":
Submit your removal request by clicking the button. This initiates the automated opt-out process.
-
Submit a manual removal request (optional but recommended):
For a more thorough removal, NumLookup also accepts manual requests. You'll need to provide your email address, full name, state of residence, phone number, a subject line, a brief description of your request, and a photo ID for identity verification. This additional step helps ensure your data is fully removed from their system.
Processing Time
NumLookup states that removal requests can take up to 45 days to process. This is significantly longer than many other data brokers. Be patient and check back after the full processing window has passed before assuming the removal didn't work.
Important Things to Know
The 45-Day Wait Is Real
Unlike some data brokers that process removals within 24 to 72 hours, NumLookup's 45-day processing window is one of the longest in the industry. There's no way to expedite the process, so plan accordingly. Mark your calendar to check back after the wait period to confirm your data has been removed.
You May Need to Provide Photo ID
If you submit a manual removal request, NumLookup asks for a photo ID to verify your identity. This is a common but understandably uncomfortable requirement. If you choose to provide it, consider redacting sensitive details like your ID number — only your name and photo should be necessary for verification purposes.
Your Data Can Be Re-Listed
NumLookup regularly refreshes its database from data aggregators and public record sources. Even after a successful removal, your phone number and associated details can reappear when new data is imported. This is one of the most frustrating aspects of dealing with any data broker — removal is rarely permanent without ongoing monitoring.
You Have Multiple Phone Numbers? Opt Out of Each
If you have more than one phone number — a personal cell, a work phone, an old landline — you'll need to submit separate opt-out requests for each number. NumLookup treats each phone number as a separate record in their database.
Your Phone Number Is Exposed on Many Other Sites
NumLookup is just one of many reverse phone lookup and people search sites that publish your personal data. Services like Whitepages, Spokeo, TruePeopleSearch, and dozens of others likely have your phone number in their databases too. Opting out of NumLookup alone won't fully protect your privacy — each site requires its own separate removal process.
Tips for a Successful Removal
- Use a secondary email: When submitting the manual removal request, use a dedicated email address for opt-out requests so you can easily track any follow-up communication.
- Redact your photo ID: If you submit an ID for verification, black out your ID number, date of birth, and any other details beyond your name and photo.
- Search for all your numbers: Before starting the opt-out process, search each of your phone numbers on NumLookup to see which ones have listings.
- Screenshot your listing: Take a screenshot of your profile on NumLookup before submitting the removal request. This serves as documentation if you need to follow up.
- Set a 45-day reminder: Mark your calendar to check back after the full processing period to confirm the removal was successful.
- Check back regularly: Even after removal, re-check every few months since data aggregator refreshes can cause your information to reappear.
The Easier Alternative: Automate Your Removals
Removing your phone number from NumLookup is a good first step, but it's only one piece of the puzzle. Your phone number, name, and address are likely scattered across dozens — if not hundreds — of data broker and people search sites. Each has its own opt-out process, its own processing time, and its own tendency to re-list your data after removal.
PrivacyOn monitors over 100 data broker sites, including reverse phone lookup services like NumLookup, and submits removal requests automatically on your behalf. We continuously scan for re-listings and handle them as they appear, so you don't have to remember to check back every 45 days or navigate yet another opt-out form. It's the most reliable way to keep your phone number and personal information off the internet for good.
Whether you choose to opt out manually or let an automated service handle the work, the important thing is to take control of your personal data. Your phone number shouldn't be a gateway for anyone to look up where you live and who your family is.
