The best US number for freelancers working with US clients (2026)

I design brand identities and websites out of São Paulo, and almost every client I take on is in the United States. For a long time I ran all of it — the discovery calls, the "hey did you see my last message," the invoices — off my personal Brazilian number. It functioned. But there was always this small friction I couldn't ignore. A prospective client in Denver would ask for my number, I'd hand over a +55 line, and something quiet would shift. Not rudeness. Just a flicker of oh, this person is far away and this might be complicated.

That flicker costs money in freelancing. Half the job is making a stranger feel safe enough to wire you a deposit. A US number, it turns out, does a surprising amount of that work before you've said a word.

What a US number actually fixes

I didn't want a second phone. I wanted four specific problems solved, and once I wrote them down it got clear fast:

• Look like I'm set up for US work. A +1 number on my proposals and email signature signals I do this seriously, not as a side hustle from another continent.
• Take and return calls and WhatsApp on a line clients recognize, so a missed call from me doesn't look like a scam number from abroad.
• Receive OTP codes for the US tools and payment platforms that quietly assume you have a US phone — some of them simply won't finish signup without one.
• Keep my personal number private. My family, my friends here, my bank — none of that belongs in a client thread. Once you give a client your personal cell, it's theirs forever.

That last one matters more than people admit. A client isn't malicious, but boundaries erode. A US number I can point at work and only work means I can put my phone down on a Sunday without a screen full of "quick question" messages on the same line my mother uses.

Why the usual suggestions didn't work for me

Every thread online says the same two things: Google Voice or TextNow. Both are genuinely fine tools. Both also assume you're already sitting in North America.

Google Voice, to even set up, effectively wants you to be in the US with a US number to link. It isn't offered in Brazil, and it's the same story across most of Asia, Africa and South America. I spent an evening on it before accepting the obvious. TextNow is North America only too — it blocked registration from my São Paulo connection outright. I couldn't create an account at all.

So the tools everyone recommends are built for people who already have the thing I was trying to get. Frustrating, but useful to know, because it narrowed my search to providers that let you buy from anywhere.

What worked: a US number I could buy from Brazil

I landed on G100 (app.g100.us) — a US-registered app that lets you sign up and buy a number no matter where you are. I made an account from São Paulo, picked a US number, and had it live in about ten minutes. No KYC, no passport upload, no proof-of-address dance. You can buy from anywhere, which is the whole point when three other apps have already turned you away.

Price was the part that made it an easy yes: a flat $1.95/month. It's pay-as-you-go from a USD wallet billed through Stripe, so I top up when I need to and that's it. If I actually ring a client, calls are $0.03/min. It runs in the browser and on a mobile app, so I answer from my laptop while I'm working and from my phone when I'm out. The full rate card is on the pricing page.

The WhatsApp part is what sealed it for me, because most of my client back-and-forth lives there. I registered the new +1 number on WhatsApp Business, Meta sent the verification code by SMS, it landed in my G100 inbox, and I was done. The number is dedicated and WhatsApp-ready. Now clients message a US business line, and my personal WhatsApp stays mine.

Receiving OTP was the other quiet win. A couple of US platforms I use for work had refused my Brazilian number at signup. With the G100 number receiving SMS, those codes come through and I can finish the registrations I was locked out of before.

The honest limits

I'd rather tell you this up front than have you feel misled after paying. Two things to know:

• Sending SMS isn't live yet. You can receive SMS and OTP codes today, but outbound texting from the number is still coming — it's waiting on 10DLC, a US carrier registration step. For me it doesn't matter, because I message clients on WhatsApp and only ever needed the number to receive codes and take calls. If your workflow depends on texting US clients directly, wait for that to switch on.
• It's US, Canada and Puerto Rico numbers only. No Brazilian line, no other countries. Since the entire reason I wanted this was a +1 presence, that was exactly right for me — but know it before you buy.

I want to be careful here too: a US number doesn't get you around anyone's rules. WhatsApp verification works because Meta sends the code and the number receives it — that's it. This is about looking professional and protecting your privacy, not slipping past any platform.

How it stacks up

Here's the short version of what I compared, so you don't repeat my week of dead ends:

Service	Works from your country?	WhatsApp-ready?	Receive OTP?	Price
G100	Yes — buy from anywhere, no KYC	Yes — dedicated +1 line	Yes — receives SMS/OTP	$1.95/mo flat
Google Voice	No — needs US setup, not offered in most of Asia/Africa/South America	N/A from outside US	N/A from outside US	Free (US only)
TextNow	No — US/Canada only, blocks signup elsewhere	N/A from outside US/CA	N/A from outside US/CA	Free (US/CA only)

Where I've ended up

My +1 number has been running my client work for a few months now. Calls get answered because they don't look foreign and suspicious. WhatsApp threads sit on a line I'm happy to hand to anyone. And my personal number is back to being personal. For under two dollars a month, that's the cheapest upgrade to how I'm perceived that I've ever bought.

If I ever grow into a small studio and want a shared team inbox with templates and broadcasts, G100 has an optional WhatsApp Business Cloud API add-on for $10/month. I'm a team of one, so I haven't touched it — the app on one dedicated number does everything I need.

If you freelance for US or overseas clients from somewhere Google Voice and TextNow won't serve, the honest takeaway is that most of these apps aren't built for us. G100 let me, sitting in São Paulo, buy a US number and get on with the work. You can grab one at app.g100.us, and the pricing page has the full breakdown.

FAQ

Why do I need a US number if my clients already have my WhatsApp?
A US number reads as professional to US clients and keeps your personal number private. A dedicated +1 line for WhatsApp Business, calls and OTP means work stays separate from your personal chats, and clients see a number that looks set up to work with them.

Can I get a US number from outside the United States?
Yes. G100 is US-registered and you can buy a US, Canada or Puerto Rico number from anywhere, including Brazil and most of Asia, Africa and South America. There's no KYC. That's the difference from Google Voice and TextNow, which usually require you to already be in North America to sign up.

Will the number receive OTP codes for US tools and payment signups?
Yes. G100 numbers receive SMS and OTP codes today, so you can verify WhatsApp and many US tools and services that text a code to a US number. Receiving codes and voice calls both work now.

Can I send SMS to my clients from a G100 number?
Not yet. Receiving SMS and OTP works today, but outbound SMS sending isn't live because 10DLC carrier registration is still in progress. WhatsApp messaging, receiving OTP codes and voice calls all work right now.
