Why You Need a Phone Audit
Your phone number is a key piece of personal information that can be used to contact you, identify you, and in some cases, even access your accounts. In today's digital world, most of us have shared our phone numbers widely—often without realizing how exposed they've become.
Consider these facts:
- The average person has shared their phone number with over 40 websites and services
- Many companies sell or share your contact information with third parties
- Data brokers actively collect and sell phone numbers as part of personal profiles
- Once your number is in a spam database, it can be shared indefinitely
- 86% of unwanted calls come from numbers that were exposed through data breaches or marketing lists
A "phone audit" is a systematic process of discovering where your phone number exists online, assessing the risk of each exposure, and taking steps to remove or limit that exposure where possible. This guide will walk you through this process step by step.
By conducting a thorough phone audit, you can significantly reduce the number of nuisance calls, limit your exposure to scams, and regain control of your personal information.
Preparation: What You'll Need
Before you begin your phone audit, gather these tools and information:
Essential Tools
- Computer with internet access
- Notepad or spreadsheet for tracking findings
- Access to your email accounts
- A secure password manager (recommended)
- Several hours of uninterrupted time
Information to Gather
- Your current and previous phone numbers
- All email addresses you use
- List of online accounts you remember creating
- Social media accounts you've used
- Online shopping sites you've used
Privacy Consideration:
Some of the audit techniques described in this guide involve searching for your personal information online. Consider using a private browsing window or a VPN for additional privacy during this process.
Creating Your Audit Tracker
Before you begin, create a simple tracking document to record your findings. This will help you keep track of where your number is exposed and what actions you've taken.
| Website/Service | Type of Exposure | Risk Level | Action Required | Status |
|---|---|---|---|---|
| Example: Facebook | Profile information | Medium | Set to "Only Me" visibility | Complete |
| Example: Online Shopping Site | Account information | Low | Check privacy settings | Pending |
| Example: Data Broker Site | Public directory | High | Submit opt-out request | In progress |
This example table shows how you might track your findings. You can create a similar table in a spreadsheet program or even use a simple notebook.
Step 1: Finding Your Digital Footprint
The first step in your phone audit is to discover all the places where your phone number might be accessible online. Here are several methods to help you find your digital footprint:
1. Search for Your Phone Number
Begin with a basic search to see what's publicly available:
- Use search engines (Google, Bing) to search for your phone number in various formats:
- With and without the country code
- With and without spaces or dashes
- Example: "07123 456789", "07123456789", "+447123456789"
- Use quotes around your number for more precise results (e.g., "07123 456789")
- Search specifically in images, as phone numbers sometimes appear in posted photos or scanned documents
Pro Tip:
If searching for your own number feels uncomfortable, try running the same searches on a friend's number (with their permission) to get familiar with the process first.
2. Check Your Email Accounts
Your email contains a wealth of information about services you've signed up for:
- Search your email for:
- Your phone number
- "Registration" or "Welcome"
- "Account created" or "New account"
- "Verify your phone" or "Phone verification"
- "Two-factor authentication" or "2FA"
- Look for confirmation emails from online services
- Check for order confirmations from online retailers
- Look for newsletter subscriptions that might include your phone number
This will help you create a list of services where your phone number might be stored, even if it's not publicly visible.
3. Check Data Broker Sites
Data brokers collect and sell personal information, often including phone numbers:
- Visit major people search websites to see if your information is listed:
- 192.com
- Whitepages
- Spokeo
- PeopleFinders
- BeenVerified
- TruePeopleSearch
- Search using your name, address, and other identifying information
- Look for "preview" information that might show parts of your phone number
Important Note:
Most data broker sites will show you that they have your information but require payment to see the full details. You don't need to pay—just knowing they have your data is enough to take action (which we'll cover in Step 3).
4. Check Social Media Profiles
Many people inadvertently share their phone numbers on social media:
Check these platforms:
- Twitter/X
- TikTok
Look in these locations:
- Contact information sections
- About sections
- Profile bios
- Old posts or comments
- Business pages you've created
Remember to check privacy settings for each platform to see who can view your contact information.
5. Use a Password Manager to Find Accounts
If you use a password manager, it can help identify services where you might have accounts:
- Export a list of your saved websites (most password managers allow this)
- Review the list for any sites that might have your phone number
- Pay special attention to shopping sites, travel booking sites, and financial services
Common Places Your Phone Number Might Be Exposed
High Exposure Risk
- Social media profiles
- Public directories
- Data broker sites
- Business listings
- Forum/blog comments
- Classified ads
Medium Exposure Risk
- Online shopping accounts
- Food delivery services
- Travel booking sites
- Event registration forms
- Job application sites
- Loyalty program accounts
Controlled Exposure
- Banking accounts
- Insurance portals
- Government services
- Healthcare portals
- Utility accounts
- Password-protected accounts
Step 2: Assessing the Risk
Once you've identified where your phone number appears, the next step is to assess the risk associated with each exposure. Not all exposures are equally concerning.
| Risk Level | Characteristics | Examples | Priority |
|---|---|---|---|
| High |
|
|
Immediate action |
| Medium |
|
|
Within 1-2 weeks |
| Low |
|
|
Check security settings |
For each place you found your phone number, assess the risk level and add it to your tracking document. This will help you prioritize which exposures to address first.
Questions to Ask When Assessing Risk
How accessible is this information?
Can anyone see it, or is it behind a login? Is it restricted to your contacts or connections?
What other personal information is connected to your phone number?
Is your full name, address, email, or other identifying information also visible?
Is this a service you use regularly?
Is it necessary for the service to have your phone number, or can you function without it?
What is the company's data handling reputation?
Have they had data breaches? Do they have a reputation for selling user data?
Is there an option to control or remove this information?
Can you adjust privacy settings or request removal?
Step 3: Taking Action to Reduce Exposure
Now that you've identified and assessed the risk of your phone number exposures, it's time to take action. Start with high-risk exposures and work your way down.
Removing Your Number from Data Broker Sites
Data brokers represent some of the highest-risk exposures:
General Approach:
- Visit the data broker's website
- Look for "Privacy," "Opt Out," or "Do Not Sell My Information" links (usually in the footer)
- Follow their specific opt-out process, which may include:
- Filling out an online form
- Sending an email request
- Providing ID verification
- Document your request (dates, confirmation numbers)
- Follow up if your information isn't removed within the timeframe they provide
UK-Specific Data Brokers:
- 192.com (with opt-out page)
- UK PhoneBook
- InfoServe
- UK Info Directory
- Directory Enquiries (118 services)
International Data Brokers:
- Spokeo
- BeenVerified
- Intelius
- PeopleFinders
- Whitepages
Note: Some data brokers may require payment for removal or make the process intentionally difficult. Persistence is key.
Securing Social Media Profiles
Adjust privacy settings on all your social media accounts:
Facebook:
- Go to Settings & Privacy > Settings > Privacy
- Under "How people can find and contact you"
- Set "Who can see your phone number" to "Only me" or remove it entirely
- Check "About" section in your profile to ensure your number isn't listed publicly
LinkedIn:
- Go to Settings & Privacy > Visibility > Visibility of your profile & network
- Edit "Phone number visibility" to "1st degree connections" or remove it
- Check if your phone is in the contact info section of your profile
Twitter/X:
- Go to Settings > Privacy and safety > Your data
- Remove your phone number if it's connected to your account
- Check if your phone is mentioned in your bio or any pinned tweets
Similar steps should be taken for Instagram, TikTok, WhatsApp, and any other social platforms you use.
Managing Online Accounts
For each account you identified as having your phone number:
- Review privacy settings - Look for options to limit who can see your phone number
- Update contact information - Remove your phone number if it's not needed for the service
- Opt out of marketing - Look for options to opt out of marketing calls or text messages
- Close unused accounts - If you no longer use the service, consider closing the account entirely
- Review consent settings - Check for options about sharing your data with third parties
Important Note:
For accounts where your phone number is used for security (like two-factor authentication), don't remove it without setting up an alternative security method first, such as an authenticator app.
Removing Your Number from Google Search Results
Google now allows you to request removal of your phone number from search results:
- Visit the Google "Remove select personally identifiable info or doxxing content" page
- Select "Information being shown in search results"
- Select "Contact information" and then "Phone number"
- Provide the URLs where your phone number appears
- Submit the request and wait for Google's response
Note: This only removes information from Google search results, not from the original websites. You'll still need to contact those sites directly.
Register with the Telephone Preference Service (TPS)
While this won't remove your number from where it's already shared, it can help reduce unwanted calls:
- Visit www.tpsonline.org.uk or call 0345 070 0707
- Register your phone number (both mobile and landline if applicable)
- Registration is free and never expires
- It's illegal for companies to make unsolicited sales calls to numbers registered with TPS
- Allow up to 28 days for registration to take full effect
Step 4: Ongoing Privacy Management
A phone audit isn't a one-time activity. To maintain your privacy, you'll need to establish ongoing practices:
Best Practices Going Forward
- Be selective - Only share your phone number when absolutely necessary
- Use alternatives - Consider email or messaging apps instead of giving your phone number
- Read privacy policies - Check how your number will be used before sharing it
- Opt out immediately - When sharing your number, immediately opt out of marketing and data sharing
- Use a secondary number - Consider using a virtual phone number for less important services
Regular Maintenance
- Quarterly searches - Repeat your phone number search every 3 months
- Email cleanup - Unsubscribe from newsletters and marketing that might share your data
- Account review - Periodically review your online accounts and close unused ones
- Privacy checkups - Use the privacy checkup features on major platforms
- Monitor for data breaches - Use services like Have I Been Pwned to monitor for breaches
Using a Secondary Phone Number
Consider getting a secondary phone number for non-essential services:
Virtual Number Services:
- Hushed
- Burner
- Google Voice
- MySudo
- Second Phone Number
Benefits:
- Keeps your primary number private
- Can be discarded if it starts receiving too many spam calls
- Helps trace which services are sharing your information
- Can be used for online shopping, contests, etc.

What if You're Already Getting Spam Calls?
If your phone number is already receiving unwanted calls, here are steps to take in addition to your phone audit:
Use Call Blocking Features
Most smartphones have built-in features to block specific numbers or filter potential spam calls. Check your phone's settings under "Phone," "Call," or "Security" sections.
Install a Call-Blocking App
Consider apps like TrueCaller, Hiya, or Whoscall that can identify and block spam calls using regularly updated databases of known spam numbers.
Report Nuisance Calls
Report each unwanted call to the Information Commissioner's Office (ICO) and to our database here at Who-Calls.me.uk to help others identify potential scammers.
Contact Your Phone Provider
Many UK mobile and landline providers offer free call-blocking services that can be activated upon request.
Consider Changing Your Number
As a last resort, if your number receives excessive spam calls despite your efforts, changing your number might be the most effective solution. Be sure to apply all the lessons from your phone audit to protect your new number.

Frequently Asked Questions
How long will it take to complete a phone audit?
A thorough phone audit typically takes 3-4 hours spread over a few days. The initial search might take 1-2 hours, while following up with opt-out requests and account management can take additional time. For very active internet users, it might take longer as you'll have more accounts to review.
Can I ever completely remove my phone number from the internet?
It's extremely difficult to remove all traces of your phone number from the internet once it's been shared. Data brokers frequently sell information to each other, and new listings can appear even after you've removed old ones. However, you can significantly reduce your exposure and make your number much harder to find through regular audits and privacy practices.
Will data brokers actually remove my information when I request it?
Most data brokers are legally required to honor opt-out requests, particularly under GDPR in the UK and Europe. However, some may make the process intentionally difficult or slow. If you don't see your information removed within the timeframe they specify (usually 30-45 days), follow up with another request and consider filing a complaint with the ICO if they still don't comply.
How often should I repeat my phone audit?
We recommend conducting a basic phone audit (especially searching for your number online) every 3-6 months. A more thorough review of your accounts and privacy settings should be done annually. However, if you notice an increase in spam calls, it's a good idea to conduct an audit right away.
What if I need to keep my phone number public for business reasons?
If you need to maintain a public phone number for business or professional reasons, consider using a separate business line or virtual number rather than your personal phone. This creates a separation that allows you to maintain professional accessibility while protecting your personal number. Many virtual phone services offer business features like voicemail, call forwarding, and professional greetings.
