If you freelance or sell from Mexico and your clients are in the United States, you already know the small friction that costs you deals. A buyer in Texas sees a +52 number and hesitates. A US platform asks for a phone code and your Mexican SIM doesn't quite fit. You want to look local to your clients, keep WhatsApp for your business separate from your personal chats, and receive the verification codes US apps ask for. Let me walk you through how to do all three, cleanly.
I advise small business owners for a living, and this exact question — "how do I get a US number while I'm in Mexico?" — comes up constantly. The short version: most free apps won't let you, and there's one path that just works. Here's the honest breakdown.
Before you spend an afternoon downloading apps that won't cooperate, know what you're up against. The popular free number apps were built for people already inside the United States or Canada. From a Mexican connection, they close the door early.
People try to fake their location with a VPN to get around this. Sometimes a number appears — and then it can't receive the WhatsApp code, or the account gets flagged and wiped weeks later, taking your client conversations with it. That's a bad trade when your income depends on that chat history. Paid options like Hushed or Vyke exist and are fine for some people, but they carry their own app logins and monthly costs, and they weren't designed around receiving business OTPs the way you need.
| G100 | TextNow | Google Voice | |
|---|---|---|---|
| Works from Mexico? | Yes — sign up from anywhere | No — US/Canada sign-up only | No — needs US phone & setup |
| Price | $1.95/month, no contract | Free (but not reachable here) | Free (but not reachable here) |
| WhatsApp-ready? | Yes — verifies WhatsApp Business | N/A — no number to use | N/A — no number to use |
| Receive OTP? | Yes — SMS & voice codes to inbox | N/A — no number to use | N/A — no number to use |
The blunt truth: a "free" number you can't register is worth nothing. A working US number that costs less than two dollars a month beats it every time.
Whether it's WhatsApp Business or a US marketplace or a client's portal, the app sends you a one-time code and waits. So the only thing that matters is a number that can receive that code — by SMS, and ideally by voice call as a backup. A G100 US number does both. The code lands in your G100 inbox at app.g100.us, you read it, you're in. No SIM swap, no VPN games, no US address.
Done. You now run WhatsApp Business on a real US number, take and make US calls at $0.03/min, and your personal Mexican line stays private.
One honest heads-up: right now G100 numbers receive SMS and OTP codes — which is exactly what WhatsApp verification and most US sign-ups need. Sending your own outbound SMS from the number isn't switched on yet; it's coming after US 10DLC registration clears. So for receiving codes, WhatsApp, and calls you're fully covered today. If sending your own text blasts is essential to you, know that piece is still on the way. G100 sells US, Canada and Puerto Rico numbers, and the WhatsApp verification itself is done by Meta.
Once you're verified, don't leave the profile empty. Add your business name in English, a clear category, your logo, your hours in the client's timezone, and a short greeting so a first-time message gets an instant reply. A US number attached to a complete, professional profile is what turns a cautious American buyer into someone comfortable paying you.
If you grow into a team answering the same number, or you want to broadcast to your client list, G100 also offers the official WhatsApp Business Cloud API as a $10/month add-on. Start with the phone app, and upgrade only when the volume genuinely calls for it.
Yes. With G100 you can sign up from anywhere in the world, including anywhere in Mexico, and get a dedicated US or Canada number. There's no requirement to live in the United States, and no US address or documents are needed.
Yes. A G100 US number receives SMS one-time-password codes and voice-call codes in your inbox. That covers WhatsApp Business verification and OTPs from many US services. Note that sending your own outbound SMS is not switched on yet — you can receive codes and make and take calls today.
TextNow only allows sign-ups from the United States and Canada, so it blocks registration from a Mexican connection. Google Voice needs a US phone and US setup and is not offered to people setting up from Mexico. Both leave you stuck before you even get a number.
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.
No. G100 does not ask for KYC or documents to get a US, Canada or Puerto Rico number. You sign up, choose a number, fund your wallet and activate it — that's the whole process.
