A shop owner in Lusaka messaged me last month with a very specific problem. She sells shea butter and crafts to buyers in the US and UK, mostly through WhatsApp and a couple of marketplace apps. Her Zambian number worked fine for local business, but two things kept tripping her up: overseas buyers hesitated to send money to a +260 number they didn't recognise, and half the international sign-up forms she tried refused to text an OTP to a Zambian line at all.
If that sounds like your week, you're not alone. Plenty of Zambian sellers, freelancers and small businesses want a US number — for a more trusted WhatsApp Business presence, for talking to international customers, and simply to receive the verification codes that so many foreign services send. Here's what actually works from Zambia, and what quietly doesn't.
This is the part that wastes people's data before they find the real answer. The popular "free US number" apps were built for people already living in North America. From a Zambian connection, they mostly won't even let you in.
Some people try to fool the free apps with a VPN. Even when a number appears, it often can't receive the code you actually needed, or the account gets flagged and wiped weeks later. That's a bad foundation for a business that runs on WhatsApp.
| G100 | Google Voice | TextNow | |
|---|---|---|---|
| Works from Zambia? | Yes — buy from anywhere | No — not available | No — US/Canada sign-up only |
| Price | $1.95/month, no contract | Free (but not reachable here) | Free (but not reachable here) |
| WhatsApp-ready? | Yes — receives the SMS/OTP code | N/A — no number to use | N/A — no number to use |
| Receive OTP? | Yes — codes land in your inbox | No number here | No number here |
The honest summary: a "free" number you can't reach costs you a wasted weekend. A working US number at under $2 a month costs you less than a couple of soft drinks and actually does the job.
G100 is a US-registered app that sells you a dedicated US or Canada business number you can use from anywhere — Lusaka, Ndola, Kitwe, wherever you are. It runs in your browser and in a mobile app. A few things that matter for Zambia specifically:
One honest heads-up: right now G100 numbers receive SMS and OTP codes and make and receive calls, but sending your own outbound SMS is not switched on yet — that's coming after US 10DLC verification clears. For WhatsApp sign-up, receiving codes, and calls, you're fully covered today. If blasting outbound texts is your main need, know that one piece is still on the way.
That's it. You now have a WhatsApp Business account on a proper US number, your personal +260 line stays private, and you can use that same number to receive OTP codes for the international services you sign up to.
Once you're verified, don't leave the profile blank. Add your business name, a category, your logo, hours, and a short auto-greeting so a buyer in a different time zone gets a reply even while you sleep. A US number attached to a complete, professional profile is what turns a cautious overseas visitor into someone comfortable sending you money.
If you grow into a team answering one number, or you want to broadcast to a customer list, G100 also offers the official WhatsApp Business Cloud API as a $10/month add-on. Start with the phone app and only upgrade when you actually need the shared inbox.
Yes. G100 sells US, Canada and Puerto Rico numbers with no KYC and no documents, and you can buy from anywhere in the world, including Zambia. You sign up, choose a number, fund your wallet in USD and activate it. There is no US address requirement.
Yes. G100 numbers receive SMS and OTP codes, which land in your inbox at app.g100.us. That covers WhatsApp verification, international marketplace sign-ups and most services that text a one-time code to a US number. Sending your own outbound SMS is not switched on yet.
Google Voice is not available in Zambia or most of Africa, so you cannot get a number at all. TextNow only allows sign-ups from the United States and Canada, so registration is blocked from a Zambian connection. Both are dead ends here.
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 for a shared team inbox and broadcasts.
