How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- The best 2nd phone number app in 2026 depends on how long you need the number: free apps suit a permanent personal line, while disposable apps suit short term use.
- Google Voice leads for a free permanent US number, while Burner and Hushed suit temporary numbers you can delete when done.
- Check verification support before you choose: many banks and services reject VoIP numbers for two factor codes, so a second number may not replace your main line for logins.
- Business users should look at OpenPhone or Sideline instead, since personal second number apps lack shared inboxes and team features.

Google Voice is the best free second number for most US users. It gives one free number for calls, texts, and voicemail, with transcription and forwarding to your real phone, and it carries no ads. The number stays yours as long as you use it at least once every 90 days, which suits a permanent personal line.
The limits are region and verification. Personal numbers are US only, and some banks and services reject VoIP numbers for verification codes, so Google Voice may not work for every login. A paid Workspace version exists for business use at 10 dollars per user per month. For a free, lasting personal second number, Google Voice leads.
What we like- Free for personal US use
- Voicemail transcription
- Call forwarding to your real phone
Watch out for- US residents only for personal numbers
- Number kept only with use every 90 days
- Some services reject it for verification

Free planYes
TextNow offers a free number supported by ads, with unlimited calls to the US and Canada and low cost international rates. A paid number lock in option keeps your number from being recycled, which addresses the main risk of the free tier: inactive free numbers can be reclaimed.
The trade is ads and verification. Free use shows ads, and verification support is weaker than a carrier number, so banks and some apps may reject it. For casual use on a tight budget, TextNow is the closest free alternative to Google Voice.
What we like- Free number with unlimited US and Canada calls
- Low cost international rates
- Number lock in option
Watch out for- Ads on the free tier
- Number can be recycled if inactive
- Less reliable for verification than carrier numbers

Burner is built for numbers with an expiry date. Create a number for a sale, a trip, a dating conversation, or a project, then delete it when done, with spam blocking and privacy controls beside it. A verified number option improves compatibility with verification systems that reject standard VoIP numbers.
Published prices vary across sources, so the starting price here is written as See website. Coverage is US and Canada, and a disposable model costs more over months than a free permanent number. For temporary numbers with real privacy controls, Burner is the best pick.
What we like- Disposable numbers you can delete anytime
- Stronger privacy controls
- Better verification compatibility than most VoIP numbers
Watch out for- Published prices vary across sources, so check the pricing page
- US and Canada only
- Disposable use costs more over time than a free number

Hushed suits people who want several private numbers at once, for different purposes, and the ability to delete and replace any of them instantly. It offers numbers in the US, Canada, and the UK, with forwarding to cellular for offline use, and it works well for international users who cannot get Google Voice.
There is no free tier, and published prices vary across sources, so the starting price here is written as See website. As a VoIP app, call quality depends on your connection. For private, disposable numbers with international coverage, Hushed is the strongest option.
What we like- Multiple private numbers in one app
- US, Canada, and UK numbers
- Easy delete and replace
Watch out for- No free tier
- Published prices vary across sources
- Call quality depends on internet connection

Sideline is a long term second line rather than a disposable one. It uses carrier minutes for calls with WiFi fallback, which improves reliability over pure VoIP, and it adds team features for small groups that share a business presence. That design suits freelancers and small teams who want one professional number for years.
Pricing is not published as a flat rate, so the starting price here is written as See website. Casual users who only need a number for a week will find Burner or Hushed simpler. For a business second line you plan to keep, Sideline fits.
What we like- Long term second number built to keep
- Carrier minutes for calls with WiFi fallback
- Team features for small groups
Watch out for- Pricing is not published as a flat rate
- More business focused than casual users need
- Fewer disposable options than Burner
Starting price$15 per user per month
Free planFree trial
OpenPhone is a small business phone system, not just a second number. Shared numbers, a team inbox, AI transcripts, and integrations let a small team handle calls and texts together, with auto attendants available without upgrades. That depth suits a business where several people answer the same line.
The price is 15 dollars per user per month billed annually, with a free trial. For a personal second number, OpenPhone is more than needed, and per user pricing adds up for larger teams. For a freelancer or small team that needs a professional shared line, OpenPhone leads.
What we like- Shared numbers and team inbox
- AI transcripts
- Integrations with messaging tools
Watch out for- More app than a personal second line needs
- Per user pricing adds up for teams
- Setup takes longer than personal apps

Line2 gives a business second line with call screening, vanity number options, and a desktop app beside mobile, which suits solo professionals who screen calls before answering. Paid plans cover unlimited US calls, so heavy callers avoid per minute surprises.
Published prices vary across sources, so the starting price here is written as See website. Android reviews are weaker than iPhone reviews, so Android users should trial it first. For an always on professional second line with screening, Line2 is a solid pick.
What we like- Call screening and vanity numbers
- Desktop app beside mobile
- Unlimited US calls on paid plans
Watch out for- Published prices vary across sources
- Android reviews are weaker than iPhone
- Business focus over casual use

2ndLine covers the low cost end of the market with a free tier for a basic second number and low cost paid options for more features. Setup is simple, and it suits users who want a spare number for signups and casual texting without a subscription.
The trade is scale: pricing and feature details vary by listing, support is smaller than larger apps, and verification support is limited, so it may not work for bank logins. For a cheap spare number, 2ndLine rounds out the list.
What we like- Free tier for a basic second number
- Low cost paid options
- Simple setup
Watch out for- Pricing and feature details vary by listing
- Smaller support footprint than larger apps
- Verification support is limited
How we chose
We ranked apps by cost, number longevity, privacy controls, verification support, call quality, and value at entry level pricing. We favored apps that keep a number as long as you need it, since a recycled number breaks every account tied to it, and we gave extra weight to privacy controls such as delete and replace and spam blocking.
We also weighed verification honestly. A second number that cannot receive bank codes is still useful for calls and texts, but it cannot replace a carrier number for logins, so we flagged that limit wherever it applies. Price conflicts across sources were handled by writing "See website" where published figures disagreed, so readers check the vendor pricing page rather than trusting a stale number.
Buying guide
Start by naming how long you need the number. For a permanent personal line, pick Google Voice or TextNow with number lock in. For a number tied to a sale, trip, or project, pick Burner or Hushed and delete it when done. For a business line, pick Sideline, OpenPhone, or Line2 for team and screening features.
Next, test verification before you rely on it. Try the number with the services that matter most, such as your bank, email, and messaging apps, during the trial, since VoIP numbers are rejected by some verification systems. Keep your carrier number for critical logins even after adding a second line.
Finally, check porting and number rules. Some apps let you port a number in or out, while others do not, and free numbers can be recycled after inactivity. If a number will anchor a business or many accounts, pay for a plan that guarantees it stays yours.
