How to get a US number in Argentina (2026)

Here's a scene I see constantly. A designer in Buenos Aires lands a client in Miami. A developer in Córdoba starts billing a startup in Austin. A seller in Rosario begins shipping to buyers up north. Business is going well — and then the awkward moment arrives. The client wants to call. And your number starts with +54, which to a US buyer reads as "expensive international call, better not."

So you go hunting for a US number. You download Google Voice. Nothing. You try TextNow. Blocked. An afternoon disappears. Let me hand that afternoon back to you and show you what actually works from Argentina.

Why the free apps leave you stuck

Nobody warns you about this before you burn your data on it. The popular free number apps were built for people already sitting in North America. From an Argentine connection, they quietly shut the door.

• Google Voice — not available in Argentina, and not in most of Latin America. There's no number to claim in the first place. That's the whole story.
• TextNow — North America only. It looks at where you're signing up, sees Argentina, and stops you cold at registration.

People then try to fool these apps with a VPN. Sometimes a number even appears — and then it can't receive the code you actually needed, or the account gets flagged and wiped a week later. That's not a foundation for a business your clients pay into.

To be fair, these apps are perfectly good if you live in the US or Canada. The problem isn't that they're bad. It's that they were never meant for you.

The short comparison

The plain truth: the "free" options cost nothing because you can't use them. A working US number for under two dollars a month beats a free one that doesn't exist.

What you actually need

Two things, really. A US number that can make and receive calls so clients up north reach you like a local. And a number that can receive OTP codes — for WhatsApp Business, and for the US-facing services and dashboards that text you a verification code. Meta and those services do the verifying; the number just has to catch the code. A G100 US or Canada number does exactly that, from Argentina, with no VPN games.

Step by step — done in about 20 minutes

1. Sign up. Go to app.g100.us and create your account. No documents, no KYC, no US address required.
2. Pick your number. Choose a US or Canada number. If most of your clients are in one city, grab that area code — a New York or Miami number reads as local to them.
3. Activate it. Fund your wallet and switch the number on for a flat $1.95/month. You pay in USD through Stripe, so your international card works fine, pay-as-you-go, no contract.
4. Use it in the browser or the app. Make and take calls right from app.g100.us or the mobile app. Calls run $0.03/min. Your Argentine line stays private.
5. Register WhatsApp Business (optional). Install the WhatsApp Business app (the green business one), enter your G100 number with the +1 code, and ask Meta to send the code.
6. Grab the code from your G100 inbox. The OTP arrives inside your G100 inbox. Copy it into WhatsApp Business and you're verified. If the SMS is slow, tap "Call me" — Meta phones the number and reads the code out loud, and G100 numbers take calls too.

That's it. A proper US number for calls and codes, and your personal +54 stays yours.

One honest heads-up: right now G100 numbers receive SMS and OTP codes — which covers WhatsApp verification and the OTPs you need to sign up for US services — and you can make and receive calls today. Sending your own outbound SMS from the number isn't switched on yet; that comes after the US 10DLC registration clears. So for receiving codes, calling and WhatsApp sign-up, you're fully covered. If outbound texting is critical for you, know that piece is still on the way.

Why the US number pays for itself

Under two dollars a month is less than a coffee, and it changes how clients see you. A US number on your invoice, your email signature, your WhatsApp Business profile — it says "I'm easy to reach and I'm set up for the US market." For a freelancer chasing overseas clients, or a seller shipping abroad, that little bit of trust is often the difference between a reply and silence.

If you later grow into a team sharing one number, or you want to send broadcasts to a customer list, G100 also offers the official WhatsApp Business Cloud API as a $10/month add-on. Start with the basics, upgrade only when you genuinely need it.

FAQ

Can I get a US number from Argentina without a US address or documents?

Yes. G100 sells US, Canada, and Puerto Rico numbers with no KYC and no documents. You can sign up from Buenos Aires, Córdoba, Rosario, or anywhere in Argentina, pick a number, fund your wallet, and activate it in a few minutes.

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

Google Voice is not available in Argentina — you cannot get a number to begin with. TextNow only allows sign-ups from the United States and Canada, so it blocks registration from an Argentine connection. Both leave you stuck before you even start.

Can I use a G100 US number to receive OTP codes and register WhatsApp?

Yes. A G100 number receives SMS and OTP codes in your inbox, including the WhatsApp Business verification code. Meta sends the code, it lands in your G100 inbox, and you copy it in to verify — all from Argentina, no VPN tricks.

How much does a G100 US number cost, and how do I pay from Argentina?

A flat $1.95 per month per number, with no contract. You pay in USD through Stripe from a pay-as-you-go wallet, so any international card works. Calls are $0.03 per minute. An optional WhatsApp Business Cloud API add-on is $10 per month.
