Cheapest US number to buy in Colombia (2026)

If you freelance or sell online from Colombia, sooner or later a US number stops being a nice-to-have and becomes something you actually need. A client in the States wants to text you. A platform asks for a "US phone number" to verify your account. WhatsApp is where half your buyers live, and a +1 number simply looks more solid to them than a personal Colombian line you'd rather not hand out.

So the question I hear from designers in Medellín and store owners in Bogotá is always the same: what's the cheapest way to get one that actually works from here? Let me answer that plainly.

Why the free apps let you down

The first instinct is to grab a free app. It rarely ends well from Colombia, and here's the honest reason why.

Google Voice — you can only set it up from inside the United States. From a Colombian connection it won't hand you a number at all. That's the whole story: no number, no code, nothing to use.
TextNow — North America only. It checks where you're signing up from, sees Colombia, and stops you at registration.

People try to force it with a VPN. Sometimes a number appears, then it can't receive the WhatsApp OTP, or the account gets flagged and wiped a week later — usually right after you've given the number to a few customers. For a freelancer or a shop, that's not a small annoyance. It's your reputation and your income.

The short comparison

	G100	Google Voice	TextNow
Works from Colombia?	Yes — buy from anywhere	No — US setup only	No — US/Canada sign-up only
Price	$1.95/month, no contract	Free (but unreachable here)	Free (but unreachable here)
WhatsApp-ready?	Yes — verifies the account	N/A — no number to use	N/A — no number to use
Receive OTP?	Yes — SMS codes land in your inbox	N/A	N/A

The point is blunt: "free" only counts if you can actually reach it. A number that costs under two dollars a month and works today beats a free one you can never sign up for.

What "cheapest that works" really means

Cheap is easy to promise. The trick is cheap and functional from Colombia — a number you can buy without a US bank account, that receives the OTP codes you need, and that Meta will accept for WhatsApp Business verification.

That's where G100 fits. It's a US-registered app that sells you a dedicated US (or Canada, or Puerto Rico) business number for a flat $1.95 a month. No contract. No KYC, no documents. You pay in USD from a pay-as-you-go wallet through Stripe, using a normal card — no US bank required. And crucially, the number receives SMS and OTP codes right in your inbox, which is exactly what WhatsApp and most US sign-ups ask for.

How to buy it from Colombia — about 15 minutes

Sign up. Go to app.g100.us and create your account. No documents, no KYC.
Pick your number. Choose a US number. If most of your clients are in one US city, pick that area code — it reads as local to them.
Fund your wallet. Add a bit of balance with your card through Stripe and activate the number for a flat $1.95/month. Pay-as-you-go, nothing locking you in.
Use it in the browser or app. Your inbox for calls and SMS lives at app.g100.us and in the mobile app. Calls run $0.03 per minute if you need them.
Verify WhatsApp Business. Install the WhatsApp Business app, enter your new +1 number, and request the code. Meta's OTP arrives in your G100 inbox — copy it over and you're verified. If SMS is slow, tap "Call me" and Meta reads the code out, since G100 numbers take calls too.

One honest heads-up. Right now G100 numbers receive SMS and OTP — which covers WhatsApp verification and signing in to US services. Sending your own outbound SMS from the number isn't switched on yet; that comes after US 10DLC verification clears. So for receiving codes, calls, and WhatsApp you're fully set today. If outbound texting is essential for your workflow, know that piece is still on the way.

Who this is really for

Freelancers who want a professional line for US clients without exposing their personal Colombian number. Sellers who run their store on WhatsApp and want the trust a +1 number brings. Anyone who keeps hitting "US phone number required" on a signup form. For all of them, the maths is simple — under $2 a month, no paperwork, working from home in Colombia.

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

FAQ

What is the cheapest US number I can buy from Colombia?

G100 sells a dedicated US number for a flat $1.95 per month, with no contract and no documents. You can buy it from Bogotá, Medellín, Cali or anywhere in Colombia, pay in USD through Stripe from a pay-as-you-go wallet, and use it in the browser or the mobile app.

Can a US number bought in Colombia receive OTP and WhatsApp codes?

Yes. A G100 US number receives SMS one-time passwords and the WhatsApp verification code straight into your inbox. That is exactly what you need to register WhatsApp Business and to sign in to US services that text a code.

Why don't free apps like Google Voice and TextNow work in Colombia?

Google Voice is not available to set up outside the United States, so Colombians cannot get a number. TextNow only allows sign-ups from the US and Canada and blocks registration from a Colombian connection. Both leave you stuck before you even have a number.

Do I need a US bank account or documents to buy the number?

No. G100 asks for no KYC and no documents for a US, Canada or Puerto Rico number. You sign up, pick a number, fund your wallet with a card through Stripe, and activate. No US bank account is required.

Skip the apps that were never built to work from here. Buy a US number that does — from anywhere in Colombia — at app.g100.us, and check the full breakdown on the pricing page.
