How to use a phone number bought in Elooo System as your WhatsApp number

Buy the number in Settings › Phone System › Phone Numbers, turn on call forwarding to a cell phone you own, then go to Settings › WhatsApp and connect WhatsApp with that number. The verification code arrives by phone call or as an SMS in Conversations.

Updated on

Before you start

  • You need permission to buy numbers and to change WhatsApp settings in your account.
  • You need a Facebook account with access to your company's Meta business portfolio (if there is none, one is created during the process).
  • Keep a personal cell phone handy to receive a call with the code, in case the number you bought only supports voice.
  • If the number supports SMS, the code arrives as an incoming message in Conversations.
  • A2P registration (for SMS in the US) is not required to connect the number to WhatsApp, but it is recommended if you also use it for SMS.
Where to find it

Settings › Phone System › Phone Numbers › Add Number · then Settings › WhatsApp › Connect WhatsApp

Step by step

Buy the number and set up forwarding

  1. Open Settings › Phone System and go to the Phone Numbers tab.
  2. Click Add Number, pick the country and a number from the list, and confirm the purchase.
  3. Open that number's settings and set up Call Forwarding to a cell phone you can answer. That is how you get the code if you choose verification by phone call.

Connect the number to WhatsApp

  1. Open Settings › WhatsApp and click the button to connect WhatsApp.
  2. Click Sign in with Facebook and log in with the account linked to your company's business portfolio.
  3. Click Get Started and fill in your business details: portfolio, name, website or page, and country.
  4. Pick your existing WhatsApp Business account or create a new one.
  5. Create the profile: account name, display name, and business category.
  6. Enter the number you bought in Elooo System and choose the verification method:
    • Phone call, if the number is voice-only (forwarding must be on);
    • SMS, if the number supports text messages.
  7. Get the code: by call on the forwarding phone, or in Conversations as an incoming message from Meta (on desktop or in the mobile app).
  8. Enter the code, review the requested permissions, and authorize the connection.
  9. When the confirmation appears, send a test message from Conversations.

Tips

  • Use a number dedicated to WhatsApp: it avoids mixing the SMS channel and the WhatsApp channel in the same conversation.
  • Keep call forwarding on: Meta may ask you to verify again later.

Common problems

  • The call with the code never comes → Call forwarding is off or points to the wrong number. Fix it in Phone Numbers and request the code again.
  • I chose SMS and don't see the code → Open Conversations and look for an incoming message on the number you bought. If the number doesn't support SMS, repeat the process with the phone call option.
  • "This number is already registered to an existing WhatsApp account" → Either a personal WhatsApp exists on that number (delete it in the app: Settings › Account › Delete my account; chat history will not carry over), or the number is with another WhatsApp provider: create a new WhatsApp Business account and migrate the number to it.
  • "Message undeliverable" right after connecting → The customer has no WhatsApp on that number, or you are sending an authentication template to an India (+91) number, which is not allowed.

Frequently asked questions

Do I need to finish A2P registration first?

No. The number can be connected to WhatsApp without A2P registration. Still complete it if you also send SMS to the US.
