How to Use a US Number on WhatsApp Business

US phone number on WhatsApp Business makes your brand look local to American customers, keeps your personal number private, and gives you one professional line for sales and support. The good news: you don’t need to live in the US or own a US SIM card to get one.

In this guide, we’ll walk you through the full process, from buying a WhatsApp-ready US number on Cubo Mobile to sending your first message as a business.

Why use a US number for WhatsApp Business?

• Look local to US customers. A +1 number builds instant trust with American buyers, partners and clients.
• Keep your personal number private. Separate your business chats from your personal life.
• Work from anywhere. Your number lives in the Cubo Mobile app, so you can receive SMS and calls on it wherever you are.
• No US SIM card or contract. Everything is digital, with no store visit, paperwork or roaming fees.
• Choose your area code. Pick an area code that matches the city or state you want to be associated with.

What you need before you start

• A smartphone (Android or iPhone)
• The Cubo Mobile app or website account
• A debit or credit card to pay for your plan
• About 10 minutes

Step 1: Buy a WhatsApp-ready US number from Cubo Mobile

Not every virtual number works with WhatsApp. Many cheap numbers get rejected during verification. That’s why Cubo Mobile offers a dedicated WhatsApp plan that is built and tested for WhatsApp registration.

1. Open the Cubo Mobile app or website and create your account.
2. Go to Virtual Numbers and select United States.
3. Choose the WhatsApp number type. Make sure you pick the WhatsApp plan, not the Social/OTP plan, which does not support WhatsApp.
4. Pick your preferred area code and select a number from the list.
5. Choose your billing period (monthly, 3 months or 12 months) and complete checkout.

Your number becomes active in your Cubo Mobile account right after payment, and incoming SMS and calls are included in your plan.

Tip: If your number doesn’t work with WhatsApp, Cubo Mobile offers a refund. You’re not taking a risk by trying.

Step 2: Download WhatsApp Business

WhatsApp Business is a free app made by WhatsApp for small businesses. It’s separate from the regular WhatsApp app, so you can run both on the same phone: your personal number on WhatsApp, your US number on WhatsApp Business.

• Android: Download “WhatsApp Business” from the Google Play Store.
• iPhone: Download “WhatsApp Business” from the App Store.

Make sure you install the official app published by WhatsApp LLC.

Step 3: Enter your US number

1. Open WhatsApp Business and tap Agree and continue.
2. When asked for your phone number, select United States (+1) as the country.
3. Enter your new Cubo Mobile number without the +1, which is added automatically.
4. Tap Next and confirm the number is correct.

Double-check every digit. A typo here means the code goes to someone else’s number.

Step 4: Receive your verification code in Cubo Mobile

WhatsApp will now send a 6-digit verification code to your US number.

1. Open the Cubo Mobile app and go to your number’s Messages inbox.
2. You’ll see an SMS from WhatsApp containing your code. It usually arrives within a minute.
3. Go back to WhatsApp Business and enter the 6-digit code.

Didn’t get the SMS? Wait for the timer in WhatsApp Business to run out, then tap Call me. WhatsApp will call your US number and read out the code. Incoming calls are included in your Cubo Mobile plan, so you can answer the call right in the app.

Tip: Don’t request new codes over and over. Too many attempts can temporarily lock verification. If a code doesn’t arrive, wait for the timer before trying again.

Step 5: Set up your business profile

Once verified, WhatsApp Business asks you to set up your profile. This is what customers see, so take a few minutes to get it right:

• Business name: Use your real brand name. You can’t change it freely later.
• Category: Choose what best describes your business (e.g., Retail, Professional Services).
• Profile photo: Upload your logo.
• Description: One or two lines about what you do.
• Business hours, address, email and website: Add whatever applies.

You can edit everything except your name anytime under Settings > Business tools > Business profile.

Step 6: Turn on the tools that save you time

WhatsApp Business comes with free tools that make you look professional and reply faster:

• Greeting message: Automatically welcome new customers.
• Away message: Auto-reply outside business hours so nobody feels ignored.
• Quick replies: Save answers to common questions and send them with a shortcut like “/price”.
• Catalog: Show your products or services with photos and prices right inside the chat.
• Labels: Organize chats by status, like “New customer”, “Paid” or “Follow up”.

You’ll find all of these under Settings > Business tools.

Step 7: Secure your account

Protect your business line with two-step verification:

1. Go to Settings > Account > Two-step verification.
2. Tap Turn on and create a 6-digit PIN.
3. Add a recovery email.

This stops anyone from registering your number on another device without your PIN.

Important: keep your number active

Your WhatsApp Business account is tied to your phone number. If your Cubo Mobile subscription expires, you could lose access to the number. You would then be unable to re-verify WhatsApp if you change phones or reinstall the app.

To avoid any interruption:

• Turn on auto-renewal for your Cubo Mobile plan, or choose a 12-month plan for the best value and peace of mind.
• Back up your chats in WhatsApp Business under Settings > Chats > Chat backup.
