Verifying WhatsApp Business with a virtual number involves, in practice, the same steps as verifying it with any other number. The difference is where the code comes from: instead of landing in the SMS inbox of a physical phone, it arrives at the virtual number you've activated on your account. Here's the full process.
Before you start
You need the virtual number already active — that is, purchased and visible in your account. If you don't have one yet, you can pick a country and number in the virtual numbers store; the purchase takes a couple of minutes and the number is available instantly.
Step 1: start the verification process in WhatsApp Business
From the InBoxIA panel, when setting up a new WhatsApp Business line, you enter the virtual number you just activated. The system submits it to Meta to start verifying that line.
Step 2: choose how to receive the code
Meta gives you two ways to receive the verification code:
- By SMS, if the number's country supports it for this purpose (WhatsApp verification works by SMS in every country in the catalog, regardless of whether that country has general-purpose SMS enabled — those are two different things).
- By automated voice call, which reads the code out loud. It's the more reliable option if SMS is slow or doesn't arrive, and it works in every available country.
If you're not sure which to pick, the voice call tends to be the lower-friction option, especially in countries where SMS can get filtered as spam.
Step 3: enter the 6-digit code
You'll receive a 6-digit code. Enter it in the setup assistant within the next few minutes — codes expire after a short window, so it helps to have the number handy (visible from the panel) when you request it.
Step 4: complete the business profile
Once the number is verified, you set up the public profile your customers will see: business name, category, description, hours, and photo. This step isn't technical, but it matters — it's the first thing someone sees when they message you for the first time.
Step 5: connect your AI agent (optional, but this is where the value is)
With the number verified, you can now set up an AI agent to automatically answer FAQs, book appointments, or qualify leads, without having to watch the chat all day. It's the natural next step once the number is live — verifying the line is the means, not the end goal.
If something fails: most common causes
- The code doesn't arrive: wait a minute and try the alternate channel (if you tried SMS, try voice call, and vice versa).
- "This number is already in use": this can happen if the number was previously linked to another WhatsApp Business account that wasn't properly closed. InBoxIA support can resolve this by checking the number's status.
- The code arrives but throws an error: check it hasn't expired (they usually last only a few minutes) and request a new one if needed.
None of these cases require buying the number again — they're incidents of Meta's own verification process, not the line itself.
FAQ
How long does the verification code take to arrive? Usually under a minute, whether by SMS or voice call. If it takes more than a few minutes, try requesting it through the other available channel.
Can I verify the number before buying it? No, the number needs to be active in your account so it can receive Meta's code on it.
What happens if the number was previously used on another WhatsApp Business account? Meta may ask for extra verification steps. With InBoxIA numbers this is rare since they're freshly assigned, but if it happens, support walks you through it.
Do I need the WhatsApp Business app on a phone to do this? Not necessarily — you can verify and manage the number directly from the InBoxIA panel without installing the app on a handset.
Next step
If you don't have a number yet, start by choosing a country and checking availability in the virtual numbers store. And if it's already verified and you want it to reply on its own from the very first message, try InBoxIA free.
