Short answer: free apps like TextNow and Talkatone give you a US number you can try on WhatsApp. Google Voice is free too, but setup needs an existing US number. Free numbers can be recycled if unused, so for anything important — a business account, or the number your customers save — a paid number is safer.
Why people want a US number on WhatsApp
A US number keeps your personal number private, lets you run a separate account for work, and gives US customers a number they recognise. Freelancers and small businesses outside the US often want one so clients don't have to message an international number.
Method 1: free apps
These apps give you a US number that receives SMS, which is what WhatsApp needs to verify you.
- Install TextNow or Talkatone from your app store.
- Sign up and pick a number. You can usually choose from a few area codes.
- Open WhatsApp (or WhatsApp Business) and start registration with your new number, choosing the United States as the country.
- Wait for the SMS code inside the number app. If it doesn't arrive, choose Call me in WhatsApp and answer the call in the app.
- Once verified, open the number app regularly so the number isn't reclaimed.
Tip: use WhatsApp Business for anything customer-facing. It's free and adds a business profile, labels and quick replies.
Why verification sometimes fails
Services like WhatsApp can recognise some numbers as virtual, and free numbers are reused between users. If a code never arrives, try a different app or a newly assigned number rather than retrying the same one many times.
Free vs paid: which to choose
| Option | Cost | Works from abroad | Keeps the number |
|---|---|---|---|
| TextNow | Free (with ads) | Yes | Only if you keep using it |
| Talkatone | Free (with ads) | Yes | Only if you keep using it |
| Google Voice | Free | Needs a US number at setup | Yes |
| Business VoIP number | Paid monthly | Yes | Yes, while you pay |
Method 2: a paid number that stays yours
If customers will save your number, losing it is expensive. A business phone provider gives you a US number — often with a choice of area code — that stays yours while you pay, works in an app on your phone and laptop, and usually adds call recording and team features.
Before you buy, check three things: that the provider supports SMS on the number (WhatsApp needs it for verification), that you can choose the area code you want, and how easy it is to cancel.
See our dialer and cloud phone comparison for providers that offer US numbers, or look up an area code to choose one.
FAQ
Why does WhatsApp reject my free number?
WhatsApp and other services can recognise some numbers as virtual and refuse them. Popular free numbers are also often recycled, so a number may already have been used. Trying a different app, or a paid number, usually fixes it.
Can I keep a free US number permanently?
Usually only if you keep using it. Free apps reclaim numbers that sit unused for a while. Google Voice numbers are more permanent, but setup needs a US number.
Is it legal to use a virtual number for WhatsApp?
Using a virtual number for privacy or business is legal in most countries. Using it to impersonate someone or get around a ban is not, and breaks WhatsApp's terms.
