Your phone number is one of the most valuable pieces of personal information you own. It is tied to your identity, your financial accounts, your two-factor authentication, and increasingly, your physical location. Giving it out freely exposes you to spam, data broker collection, SIM swap attacks, and targeted scams. A burner phone or secondary number can help you take back control.
What Is a Burner Phone in 2026?
The term "burner phone" used to mean a cheap prepaid flip phone bought with cash and discarded after use. In 2026, the concept has evolved dramatically. A modern burner number is a line of software on the phone you already carry. You do not need a second device, a trip to a convenience store, or a complicated setup process.
Virtual burner number apps provide you with a real phone number that can make calls, send texts, and receive voicemails, all through your existing smartphone. When you no longer need the number, you simply delete it and get a new one.
Why You Need a Secondary Number
Every time you give out your real phone number, it can end up in a data broker's database, on a marketing list, or in a breach dataset. Here are the most common situations where a secondary number protects you:
- Online marketplace transactions — Selling items on Craigslist, Facebook Marketplace, or OfferUp without exposing your personal number to strangers
- Dating apps — Keeping your real number private until you trust a new connection
- Online shopping and signups — Using a secondary number for loyalty programs, account registrations, and newsletters
- Side hustles and freelance work — Maintaining a separate business line without paying for a full second phone plan
- Two-factor authentication backup — Having an alternate number for SMS-based verification codes
- Travel — Using a local number when visiting another country without changing your primary SIM
The Privacy Benefit Is Cumulative
Each time you use a secondary number instead of your real one, you prevent that number from being linked to your identity across databases. Over time, this significantly reduces your exposure on data broker sites and limits the personal information available about you online.
Virtual Burner Number Apps
Several apps provide virtual secondary numbers that work on your existing smartphone:
- Google Voice — Free U.S. number with calling, texting, and voicemail. Requires a Google account. Best for a long-term secondary number.
- Burner — Disposable numbers starting around $5 per month. Create and delete numbers as needed. Great for short-term use cases like marketplace sales.
- Hushed — Offers numbers from multiple countries. Plans start at around $4 per month. Good for international use.
- MySudo — Provides up to nine virtual identities, each with its own phone number, email, and browser. More comprehensive privacy tool.
- TextNow — Free ad-supported option with a U.S. or Canadian number. Limited features compared to paid options.
Physical Prepaid Phones
If you want a completely separate device, physical prepaid phones are still available for $10 to $50 at most retailers. Prepaid SIM cards can be activated with minimal personal information in many cases. However, keep in mind that these phones are not truly anonymous. Law enforcement can track them through cell tower triangulation, call records, and network activity logs.
Burner Numbers Are Not Untraceable
Neither virtual burner apps nor physical prepaid phones provide complete anonymity. Law enforcement can still identify users through carrier records, IP addresses, device identifiers, and cell tower data. Burner numbers are a privacy tool, not an invisibility cloak. They protect you from casual snooping, data brokers, and marketers — not from determined law enforcement with legal authority.
Best Practices for Using a Secondary Number
Separate Your Identities
Use your secondary number consistently for specific categories of activity. For example:
- Primary number — family, friends, medical providers, and financial institutions
- Secondary number — online shopping, social media accounts, app signups, and strangers
Use Signal With a Secondary Number
The encrypted messaging app Signal allows you to create a username so contacts can reach you without knowing your phone number at all. If you register Signal with your burner number, you add an extra layer of separation between your real identity and your communications.
Rotate Numbers When Needed
If a burner number starts receiving spam or has been given out to too many people, replace it. Apps like Burner make this simple — you can create a new number in seconds and let the old one expire.
Combine With Email Aliases
A secondary phone number works best when paired with email aliases. Services like SimpleLogin, AnonAddy, or Apple's Hide My Email let you create disposable email addresses. Together with a burner number, you can sign up for services without exposing any of your real contact information.
When a Burner Number Is Not Enough
A secondary phone number keeps your real number private, but it does not remove personal information that is already exposed online. If your name, address, and primary phone number are already listed on data broker sites, that damage is done and needs to be addressed separately.
PrivacyOn monitors over 100 data broker sites and automatically removes your personal information when it appears. Combined with dark web monitoring and 24/7 alerts, PrivacyOn addresses the exposure you already have while a burner number helps prevent future exposure. Family plans cover up to five people starting at just $8.33 per month.
Getting Started
Start by choosing one app from the list above and getting a secondary number today. Use it the next time you sign up for a service, sell something online, or give your number to someone you do not fully trust. It is a small change in habit that pays significant dividends for your privacy over time.
