People search for "second phone number app" for very different reasons. Some want to protect their personal number from dates or strangers. Some need a business line without a second phone. Some are trying to verify a specific app without linking it to their identity. Some need a number from a specific country.
The apps that dominate this space — Burner, Hushed, Google Voice, and virtual number services like VRNUM — are designed for different primary use cases. Choosing the wrong one costs you either money, the functionality you needed, or both.
This comparison is structured around use cases rather than features, because a feature checklist is meaningless if the numbers do not actually work for what you need.
Burner
The concept: Burner pioneered the "disposable second phone number" category. You get a US or Canadian number, use it for a period, and then "burn" it (cancel and get a new one). The original use case was Craigslist, dating apps, and any situation where you need to give someone a callback number without giving out your real number.
What it does well:
- Simple, consumer-friendly app
- Good for giving strangers a number that cannot be traced to you
- Clean interface for calling and texting
- "Burn" feature lets you abandon a number and move to a fresh one
What it does not do:
- Numbers are VoIP-based and fail carrier type checks on WhatsApp, Instagram, Meta platforms, and banking apps
- Only US and Canadian numbers
- Not a privacy-first service in the cryptographic sense — Burner knows who you are via your App Store account and payment method
- No international country codes
- Numbers expire when you stop paying; accounts linked to a Burner number get locked out if it lapses
Cost: Monthly plans start at approximately $4.99/month for one number. Annual plans reduce the per-month cost.
Best for: Personal privacy from individuals — keeping your real number away from Marketplace sellers, casual dates, service providers, and strangers.
Hushed
The concept: Similar to Burner in positioning — a second US/Canadian number for privacy. Hushed differentiates with slightly more flexible pricing and a "lifetime number" option.
What it does well:
- Works as a personal privacy layer (same use case as Burner)
- Lifetime number credits give you a number without a recurring subscription
- Decent app for calling and texting within US/Canada
What it does not do:
- Same VoIP limitations as Burner — fails on WhatsApp, Meta platforms, financial apps
- No international country codes outside North America
- Credit card or App Store payment required; no crypto option
- No web dashboard — requires the app to receive messages
Cost: Monthly plan approximately $1.99/month for a single number. Lifetime numbers from around $25.
Best for: Same use case as Burner — personal privacy from individuals, not a tool for platform verification or international use.
Google Voice
The concept: A free US phone number tied to your Google account, with calling and texting available through the app or browser.
What it does well:
- Free
- Clean web and app interface
- Good voicemail transcription
- Works for calling and texting with mainstream apps that are not strict about number type
- Browser-based access — no app required
What it does not do:
- Only available to people who already have a US phone number (required for initial setup)
- VoIP numbers fail on WhatsApp, Instagram, Facebook, and banking apps
- No international country codes — US numbers only
- Tied to your Google identity — not anonymous
- No crypto payment option
Cost: Free for personal use. Business use requires Google Workspace.
Best for: US residents who want a free secondary US number for calling and texting with people and mainstream apps. Not suitable for platform verification or any use that requires an anonymous or non-US identity.
VRNUM
The concept: A dedicated virtual phone number service built around international coverage, real carrier-allocated numbers (not VoIP), and privacy through zero-KYC crypto payment.
What it does well:
- 50+ countries — get a number from US, UK, Germany, France, Canada, Australia, Netherlands, and more
- Real carrier allocations — numbers return "mobile" in carrier lookups, meaning they work on WhatsApp, Instagram, Telegram, Google, and banking apps where VoIP numbers fail
- Two product types: OTP single-use activations (per use) and permanent monthly/yearly subscriptions
- Crypto payment only — Bitcoin, USDT, Ethereum, Litecoin. Zero KYC, no ID, no personal information required
- Web dashboard — receive SMS from any browser, no app needed
- Refund policy — OTP activations that fail to deliver a code are refunded
What it does not do (trade-offs):
- Not free
- Not optimized as a calling app (primarily SMS/verification focused, though calls are supported)
- Crypto payment only — no credit card option
Cost: OTP single-use activations priced per activation. Monthly virtual numbers priced by country, starting from a few dollars per month.
Best for: People who need verification to actually work — on WhatsApp, Instagram, Telegram, Google, or a financial app. People who need numbers from countries outside North America. People who want to pay anonymously with crypto and have zero identity trail.

Decision Guide: Which Second Number App Is Right for You?
You want to keep your real number private from people in your personal life (dates, Craigslist sellers, neighbors): Burner or Hushed both do this well. Hushed is slightly cheaper; Burner has a cleaner burn-and-replace workflow.
You want a free second US number for calling and texting: Google Voice — but only if you are already in the US or have a US number for the initial setup.
You need to verify WhatsApp, Instagram, Telegram, or Google: None of Burner, Hushed, or Google Voice will work reliably. Use VRNUM, which provides real carrier-allocated numbers that pass the carrier type checks these platforms enforce.
You need a number from outside the US or Canada: Only VRNUM offers international country codes at this level.
You want to pay with crypto and leave no identity trail: Only VRNUM accepts cryptocurrency and requires no identity verification.
You are a developer or reseller building a product on top of virtual numbers: VRNUM has a developer API. Burner, Hushed, and Google Voice do not.
The Underlying Problem Most Comparisons Miss
Burner, Hushed, and Google Voice are all VoIP-based. That was fine five years ago, when platforms did not aggressively check carrier types. It is not fine now.
In 2026, WhatsApp, Meta (Instagram/Facebook), Google, and most banking apps run carrier type lookups on every number submitted for verification. VoIP numbers are rejected before the SMS is sent — silently, with no useful error message to the user. This is why people try Burner for WhatsApp verification, get no code, assume the app is broken, and then search for something that actually works.
The fundamental difference between VRNUM and the apps above is not the interface or the pricing — it is the number type. Real carrier allocations pass carrier type checks; VoIP ranges do not. That is the only thing that matters when you need a platform to actually send you a code.
