How to get a US number in Brazil (2026) for WhatsApp & US clients

I hear the same thing from freelancers and small sellers across Brazil every week. You're winning work from clients in the United States, or you're selling to buyers abroad on WhatsApp, and a Brazilian number keeps getting in the way. A US client sees a +55 number and hesitates. A US service asks for a phone number to send an OTP and won't accept yours. And your personal line is now stuck in a hundred customer chats forever.

So you go looking for a free US number. You download Google Voice. Dead end. You try TextNow. Blocked. A weekend disappears. Let me save you that weekend and show you what actually works from Brazil.

Why the free apps fail you here

Nobody warns you before you burn your afternoon on this. The popular free number apps were built for people already living in North America. From a Brazilian connection, they simply refuse to open the door.

• Google Voice — you can't set it up from Brazil. The sign-up isn't available here, so there's no number to get. Full stop.
• TextNow — North America only. It checks where you're registering from, sees Brazil, and stops you cold. No number, no code, nothing.

Plenty of people try VPN tricks to fool these apps. Even when a number appears, it often can't receive the WhatsApp code, or the account gets flagged and wiped a week later. Not worth your time, and definitely not worth your reputation with a paying client.

The short comparison

Here's the plain truth: the "free" options cost nothing because you can't use them from Brazil. A working number that costs under $2 a month beats a free one that doesn't exist.

What you actually need

To register WhatsApp Business, you need a number that can receive the verification code — Meta sends it by SMS, and it has to land somewhere you can read it. Meta does the verifying; the number just has to catch the code. A G100 US or Canada number does exactly that, from Brazil, with no VPN games. The same inbox also catches OTP codes from other US services, which is handy when you're setting up client tools or marketplaces.

Step by step — get it done in about 20 minutes

1. Sign up. Go to app.g100.us and create your account. No documents, no KYC.
2. Pick your number. Choose a US or Canada number. G100 sells US, Canada, and Puerto Rico numbers — if most of your clients are in one US city, pick that area code so it reads as local to them.
3. Activate it. Fund your wallet and turn the number on for a flat $1.95/month. You pay in USD through Stripe, pay-as-you-go, no contract tying you down. Calls run $0.03 per minute if you use them.
4. Install WhatsApp Business. Download the WhatsApp Business app (the green one for businesses, not regular WhatsApp) from the Play Store or App Store. It runs alongside your personal WhatsApp — they don't clash.
5. Register the number. Open WhatsApp Business, enter your new G100 number with the +1 country code, and ask Meta to send the code.
6. Get the code from your G100 inbox. Meta's SMS code arrives right inside your G100 inbox at app.g100.us. Copy it into WhatsApp Business and you're verified. If the SMS is slow, tap "Call me" — Meta will phone the number and read out the code, and G100 numbers take calls too.

That's it. You now have a WhatsApp Business account on a proper US number, your personal line stays private, and US clients see a number that looks local to them.

One honest heads-up: right now G100 numbers receive SMS and OTP codes — which is all you need for WhatsApp verification and catching one-time codes. Sending your own outbound SMS from the number isn't switched on yet (it's coming after the 10DLC registration clears). Receiving codes, taking calls, and WhatsApp all work today. If plain outbound texting is critical for you, know that one piece is still on the way.

Finish your profile so clients trust you

Once verified, don't leave it blank. Add your business name, a category, your logo, opening hours, and a short greeting so a first-time chatter gets a reply even when you're asleep and there's a time-zone gap. A US number with a filled-out, professional profile is what turns a curious lead into a client who's comfortable paying you across borders.

If you grow into a team answering the same number, or you want to send broadcasts to your client list, G100 also offers the official WhatsApp Business Cloud API as a $10/month add-on. Start with the phone app, upgrade only when you actually need it.

FAQ

Can I register WhatsApp on a US number from Brazil?

Yes. Meta lets you register WhatsApp Business on any number that can receive the verification code. A G100 US or Canada number receives that SMS code (or a voice call) in your inbox, so you can verify it while sitting in São Paulo, Rio, or anywhere in Brazil. Meta handles the verification; the number just has to catch the code.

Why don't Google Voice and TextNow work in Brazil?

Google Voice cannot be set up from Brazil — the sign-up is not available here. TextNow only allows registration from the United States and Canada, so it blocks you from a Brazilian connection. Both are dead ends, which is why people lose days trying VPN tricks that get the account flagged anyway.

How much does a G100 US number cost?

A flat $1.95 per month per number, with no contract. You pay from a pay-as-you-go wallet in USD through Stripe. Calls are $0.03 per minute. An optional WhatsApp Business Cloud API add-on is $10 per month if you need a shared team inbox and broadcasts.

Can the number receive OTP codes from other services?

Yes. A G100 number receives SMS and OTP codes, so besides WhatsApp verification it can catch one-time codes from US services in your inbox. One honest note: sending your own outbound SMS from the number isn't switched on yet — receiving codes, taking calls, and WhatsApp all work today.
