Every time you give out your real phone number — to a website, an app, a store, a delivery service — that number gets collected, sold to data brokers, and eventually ends up on people search sites where anyone can find it. That’s why you get so many spam calls and why strangers can find your address from your phone number.
The fix is simple: stop giving out your real number. Use Google Voice instead.
Google Voice gives you a free secondary phone number that you can use for online forms, deliveries, signups, and anything else that doesn’t absolutely need your real number. If that Google Voice number gets sold to data brokers or ends up on spam lists, it doesn’t matter — your real number stays private.
Here’s how to set it up and use it for maximum privacy.
Already getting spam on your real number? Run a free Optery scan to see how many data broker sites have your real phone number listed. Google Voice protects you going forward — but you still need to clean up what’s already out there.
What Is Google Voice?
Google Voice is a free service from Google that gives you a separate phone number. You can use it to make calls, send texts, and receive voicemail — all through the Google Voice app on your phone or computer. It works over Wi-Fi or cellular data, not your phone plan’s minutes.
Key features for privacy:
It’s a real phone number. Your Google Voice number works like any other phone number. Websites, apps, and services accept it for verification and account creation.
It’s completely free. Calls and texts within the US and Canada are free. No monthly fee, no subscription.
It rings on your existing phone. You don’t need a second phone. Google Voice calls and texts come through the Google Voice app on your current phone.
You can screen and block calls. Google Voice has built-in spam filtering and call screening. Spam calls to your Google Voice number get filtered automatically.
You can change or abandon it. If your Google Voice number gets compromised or starts getting too much spam, you can change it without affecting your real phone number.
How to Set Up Google Voice (Step by Step)
Setting up Google Voice takes about 5 minutes:
Step 1: Go to voice.google.com. Open your browser and navigate to voice.google.com. Sign in with your Google account.
Step 2: Choose a phone number. Google Voice will ask you to select a number. You can search by city or area code. Pick a number — it doesn’t have to match your real area code.
Step 3: Link your real phone number. Google Voice requires you to link an existing phone number to verify your account. This links the two numbers together so Google Voice calls can ring on your real phone. Don’t worry — your real number stays private. Only Google sees the connection.
Step 4: Download the Google Voice app. Install the Google Voice app on your iPhone (App Store) or Android (Google Play Store). Sign in with the same Google account.
Step 5: Configure your settings. In the app, go to Settings and adjust:
- Do Not Disturb: Turn on if you don’t want Google Voice calls to ring your phone
- Spam filtering: Make sure this is enabled (it usually is by default)
- Call screening: Enable this to hear who’s calling before you pick up
- Voicemail transcription: Turn on to get voicemails transcribed to text
That’s it — you now have a free secondary phone number ready to use for privacy protection.
When to Use Your Google Voice Number
The key to making Google Voice work as a privacy tool is using it consistently for the right situations:
Online shopping and deliveries. When a checkout form asks for your phone number, use your Google Voice number. If that retailer sells your data to brokers or gets hacked, your real number stays safe.
App signups and account creation. Most apps that require a phone number will accept a Google Voice number for verification. Use it for any non-essential account.
Loyalty programs and store cards. Those “enter your phone number for rewards” prompts are data collection machines. Use Google Voice and keep your real number off their marketing lists.
Craigslist, Facebook Marketplace, and classifieds. Never give your real number to strangers on classifieds sites. Google Voice keeps a layer of separation between you and unknown buyers or sellers.
Dating apps. If you’re sharing your number with someone you just met, use Google Voice. If things don’t work out, they can’t use your real number to find your home address through data broker sites.
Contractors and service providers. Plumbers, handymen, delivery services — anyone you need to contact temporarily but don’t want having your real number permanently.
Contest entries and surveys. These are notorious data collection tools. If you must enter, use Google Voice.
When to Use Your REAL Phone Number
There are situations where your real number is necessary:
Banking and financial institutions. Banks often require your real phone number for security verification and fraud alerts. Use your real number here.
Government agencies. The IRS, DMV, and other government services should have your real number.
Healthcare providers. Doctors, dentists, and hospitals need your real number for appointment reminders and emergency communication.
Your employer. Your workplace should have your real contact information.
Close family and friends. People you trust with your real number can keep it.
Two-factor authentication on critical accounts. While Google Voice works for many 2FA systems, some banks and financial services specifically require a non-VoIP number. Use your real number for these.
The general rule: if it’s a trusted, long-term relationship where they genuinely need to reach you — use your real number. For everything else — Google Voice.
How Google Voice Reduces Spam Calls
Using Google Voice as your public-facing number creates a natural spam buffer:
Your real number stays off data broker sites. When you use Google Voice for signups and forms, your real number doesn’t enter the data broker ecosystem. Fewer data brokers with your real number means fewer robocalls reaching your actual phone.
Google Voice has built-in spam filtering. Google automatically identifies and filters suspected spam calls to your Google Voice number. Many spam calls never even ring through.
You can replace it if needed. If your Google Voice number gets overwhelmed with spam, you can get a new one. Try doing that with your real cell phone number — it’s a much bigger hassle.
You control when it rings. Set Do Not Disturb on your Google Voice number during evenings and weekends. Spam calls go straight to voicemail without ever interrupting you.
Google Voice Limitations to Know About
Google Voice is a powerful privacy tool, but it has some limitations:
Some services reject VoIP numbers. A few banks, financial services, and two-factor authentication systems specifically require a carrier-based phone number and won’t accept Google Voice. This is the minority, but it happens.
911 limitations. Google Voice is not a replacement for your primary phone. Emergency calls through Google Voice may not work the same as through your carrier.
Requires a Google account. You need a Google account to use Google Voice, which means Google has access to your call and text data. For most people, this trade-off is worth it — but privacy purists may prefer a paid alternative.
Only available in the US. Google Voice with free phone numbers is only available in the United States. International users will need alternatives.
It doesn’t fix existing exposure. Google Voice protects you going forward by keeping your real number private. But it doesn’t remove your real number from data broker sites where it’s already listed. For that, you need data broker removal.
The Complete Phone Privacy Strategy
Google Voice is one piece of a complete phone privacy strategy. Here’s the full plan:
Step 1: Clean up existing exposure. Run a free Optery scan to see which data broker sites currently have your real phone number listed. Then remove it using Optery (free scan, paid removal from $39/year) or Incogni ($6.49/month). This addresses the damage already done.
Step 2: Set up Google Voice. Create your free secondary number using the steps above. Start using it immediately for all non-essential contacts.
Step 3: Remove your real number from social media. Go through Facebook, Instagram, LinkedIn, and all other platforms. Delete your real phone number from your profile and account settings.
Step 4: Enable spam filtering on your real number. Activate your carrier’s spam filter (T-Mobile Scam Shield, AT&T ActiveArmor, Verizon Call Filter) and enable Silence Unknown Callers (iPhone) or Spam and Call Screen (Android). Full guide: How to Stop Robocalls.
Step 5: Set up monitoring. Create a Google Alert for your phone number so you’re notified if it appears on new websites. Use continuous data broker monitoring through Optery or Incogni to catch re-listings automatically.

Frequently Asked Questions
Is Google Voice really free?
Yes. Calls and texts within the US and Canada are free. There’s no monthly fee or subscription. You just need a Google account.
Can I use Google Voice for two-factor authentication?
Most services accept Google Voice for 2FA text codes. However, some banks and financial institutions specifically require a carrier-based number. Test it with each service — if it doesn’t work, use your real number for that specific account.
Will people know I’m using Google Voice?
Not typically. Your Google Voice number looks and works like any regular phone number. The only giveaway might be a slight delay on calls since they route through Google’s servers, but most people won’t notice.
Can data brokers still find my real number if I use Google Voice?
Google Voice prevents your real number from entering NEW data broker databases. But if your real number is already on data broker sites from past usage, you need to remove it. Run a free Optery scan to check your current exposure.
Is Google Voice safe to use?
Yes, for most purposes. Google Voice encrypts calls and texts. The main privacy consideration is that Google has access to your call logs and text messages — which is the trade-off for a free service. For most people, this is preferable to having their real number on hundreds of data broker sites.
What if my Google Voice number starts getting spam calls?
Google Voice has built-in spam filtering that catches most spam. If the volume gets too high, you can get a new Google Voice number. That’s the beauty of a secondary number — it’s disposable in a way your real number isn’t.
Should I port my real number to Google Voice?
No — that defeats the purpose. The strategy is to have TWO numbers: your real number for trusted contacts and Google Voice for everything else. Porting your real number to Google Voice would make it your only number.
