Best Second Phone Number App Free in 2026

Google Voice is our pick for most people who want a free second number. A personal Google account gives you a US number for calls, texts and voicemail, with transcription and spam filtering built in. It rings on your existing phone, so you do not need a second handset, and it works across web and mobile apps.

The limits matter for business use. The free tier is for personal use in the United States, it allows one number per account, and business features sit in paid Workspace tiers starting at $10 per user per month. It also needs an existing mobile number to set up, and Google can reclaim a number left unused, so keep it active if you want to keep it.

TextNow offers a genuinely free plan, supported by ads, with a local number and unlimited nationwide talk and text. It also includes free data for select apps, which helps if you use it on a phone without a full data plan. For selling online, dating or signing up for services where you do not want to share your real number, that free tier is hard to beat.

Ads are the trade, and verification is the catch. Free TextNow numbers do not reliably receive verification codes, and paid data passes add that feature along with ad removal. Treat TextNow as a free communication number, not as the recovery number for a bank account or other sensitive service.

Burner is built for numbers with a clear end date. You pick an area code, use the number for a listing, a project or a short-term contact, then delete it when you are done. Spam blocking, quiet hours and separate inboxes per number keep that temporary contact from leaking into your personal messages.

Pricing starts at $9.99 per month, with an annual plan lowering the monthly equivalent, and a short free trial lets you test it first. Standard Burner numbers are app-based, so some platforms that require mobile-classified numbers may reject them for verification. Burner also sells verified numbers and eSIM options for users who need stronger verification support.

Hushed suits people who want several private numbers at once, such as one for selling, one for dating and one for a side project. Its unlimited plan starts at $6.99 per month for one to three numbers, and prepaid plans suit short-term use with a fixed allowance of minutes and texts. Numbers are available in many countries, not just the United States.

As a VoIP service, Hushed shares the verification limit of other second-number apps: some banks and platforms will not accept its numbers for codes. It is best for calls and texts with people, rather than as a security number for sensitive accounts. Check the allowance on your chosen plan, since prepaid plans cap minutes and texts.

Sideline is a clean second line for a solo worker who wants work calls and texts kept apart from personal ones. It includes auto-reply, business hours, group messaging and voicemail, and it uses your carrier network for calls, which can improve reliability over a purely data-based app. You can also port an existing number to Sideline.

The limit is growth. Sideline is built for one person, with no shared numbers or team inbox, so a business that hires will outgrow it. At $14.49 per month on a monthly plan, with cheaper six-month and yearly options, it also costs more than a free app, so it suits a lasting work line rather than a throwaway number.

OpenPhone, now sold under the Quo brand in some listings, is a business phone system that happens to work well as a second number. It gives a local or toll-free number, a shared inbox for teams, call recording, business texting and integrations with customer tools. A solo worker can use it, but its real strength shows when two or more people share one number.

That depth costs more than a personal app, at $15 per user per month on the entry tier in recent listings, with a free trial available. Business texting to US customers also needs registration for carrier rules, which takes time to set up. Choose OpenPhone when the number is a business asset, not just a private extra line.

Line2 gives a solo business a straightforward second line with unlimited calls and texts in the United States and Canada. It includes voicemail transcription, call forwarding, call screening and custom greetings, and it works on mobile and desktop. For a one-person business that wants a professional number without a full phone system, that scope is enough.

It does not grow into a team system, since shared numbers are not included, and its interface feels older than OpenPhone or Google Voice. At $9.99 per month, with a lower monthly equivalent on annual billing, it sits in the middle of this group on price. Test the app on your phone during a trial period before committing for a year.

TextFree, from the same company behind Sideline, offers a free second number for calls and texts in the United States and Canada, supported by ads. It is a useful free option for casual use, such as keeping a marketplace conversation separate from your personal number. Setup is quick, and the app runs on iOS and Android.

The free plan has the usual free-number limits: ads, no verification codes, and a need to use the number regularly to keep it. Paid options remove ads and add features, but the free tier already covers basic texting and calling. Do not use TextFree as the sole contact for a business or for account recovery.
