Benefits of Using WhatsApp Business with a Second Number

For many small and medium-sized businesses, WhatsApp Business has become the go-to tool for staying connected with customers. The app is familiar, free, and trusted by millions. But a common frustration arises when owners want to separate personal chats from business conversations. This is where having a second number, such as a UK virtual mobile number from gosimless, becomes a game-changer.

Running WhatsApp Business on a second number not only gives you clarity and control, it also projects a professional image. It enables you to scale customer interactions without blurring the lines between your private life and your business operations.

What is a second number and why use it for WhatsApp Business?

A second number is simply another mobile line you can use alongside your personal one. Instead of buying another SIM card or device, businesses can use a UK virtual mobile number that functions just like a standard line for receiving SMS and calls.

When you register this number with WhatsApp Business, it keeps your company identity distinct. Customers will always see your professional business number, while your personal WhatsApp remains untouched. For sole traders, freelancers, and growing teams, this separation is vital for credibility and peace of mind.

Can you run two WhatsApp accounts on one phone?

Yes. WhatsApp allows you to run both the standard WhatsApp Messenger and WhatsApp Business apps on the same device, as long as each is tied to a unique number. With a virtual second number, you can use one for friends and family, and the other for handling enquiries, orders, and support.

On Android, some devices even support app cloning, letting you run multiple versions of WhatsApp Business for different numbers. iOS is more limited, but you can still run one personal and one business version side by side. For desktop or web, WhatsApp lets you log into your business account separately, ensuring you can keep your communications organised.

How to set up WhatsApp Business with a second number

Setting up on Android

1. Download the WhatsApp Business app from Google Play.
2. Launch the app and select Agree and Continue.
3. Enter your second number (e.g. your gosimless UK virtual number).
4. Choose SMS or voice call to receive the verification code.
5. Once verified, set up your business profile with logo, description, and opening hours.

Setting up on iOS

1. Install WhatsApp Business from the App Store.
2. Open the app and accept the terms.
3. Input your second number and wait for the OTP to arrive.
4. Verify and then customise your business profile.
5. Enable quick replies, labels, and automated greetings.

Using WhatsApp Web or Desktop

While you cannot verify a new WhatsApp account directly on the web version, you can manage your account once it is active on mobile. Simply visit web.whatsapp.com or open the desktop app, scan the QR code from within your Business app, and you'll have full access on your computer.

Why a second number adds professionalism to your business

Customers feel more comfortable when they see a dedicated number for business. It signals that you take your company seriously and separates your shopfront from your personal identity. This also makes it easier to delegate communications to colleagues without risking exposure of your private mobile number.

A second number also improves trust. A UK virtual number gives your business a local presence, reassuring customers that you are genuine and accessible. This is especially important for service providers, online shops, and tradespeople operating across the country.

Keeping personal and professional life separate

Mixing personal and business messages often leads to missed opportunities and confusion. Imagine losing a customer enquiry in between family group chats or accidentally replying to a client with the wrong emoji. By maintaining two numbers, you avoid these risks entirely.

This division also supports work-life balance. When business messages only come through your second number, you can mute or schedule notifications without affecting your personal interactions. It helps create boundaries, ensuring you are responsive to customers but not overwhelmed.

Enhanced privacy and security with a second number

Using your personal mobile number for business puts your privacy at risk. Once it is public, anyone can share it, add you to spam groups, or misuse it. With a second number, you shield your personal identity while still offering a responsive customer channel.

From a security perspective, having a dedicated number for WhatsApp Business also reduces the chance of SIM-swap fraud or account compromise. Virtual numbers from providers like gosimless are not tied to physical SIM cards, adding another layer of protection.

Scaling your team with one business number

WhatsApp Business now supports multi-device access. That means multiple staff members can log into the same account using the second number, all without needing your personal phone present. This is invaluable for customer service teams who need to share the workload while keeping a consistent business identity.

With shared access, you can assign responsibilities, track responses, and make sure no customer message goes unanswered. This level of collaboration would be impossible if you only relied on your personal WhatsApp.

Managing customer expectations with automation

WhatsApp Business offers features that make customer communication smoother. With a second number, you can set up:

• Quick replies for FAQs
• Greeting messages for first-time contacts
• Away messages outside office hours
• Labels to organise chats by status (new lead, order placed, payment pending, etc.)

By automating part of the process, you free up time and still maintain professionalism. Customers get instant acknowledgement, even if you're not online.

Troubleshooting common issues when verifying with a second number

SMS code not received

• Double-check you entered the number in full UK format (+44).
• Wait a few minutes and request the code again.
• If SMS fails, use the voice call option.

Number already registered

If the number has previously been linked to a WhatsApp account, you may need to delete or migrate that account first. Virtual numbers from gosimless are issued fresh, so you avoid recycled number issues.

Switching devices

If you change phone, WhatsApp will re-verify your number. As long as your second number is active, you can re-register easily on the new device.

Is a virtual second number accepted by WhatsApp Business?

Yes, WhatsApp accepts virtual mobile numbers for Business verification, provided they can receive SMS or voice calls. gosimless numbers are designed for this exact purpose, making the verification process smooth and reliable. Unlike disposable numbers, gosimless ensures your line is stable, consistent, and exclusively yours.

Cost benefits of a second number compared to another SIM

Buying a new SIM or device means extra overheads. With a UK virtual number, you skip the hardware costs and only pay for the service. gosimless offers flexible plans, so you only invest in what you need. For businesses just starting out, this affordability can be the difference between growing online and staying invisible.
