# Embedded Signup
The **Embedded Signup** is a streamlined onboarding process offered by Meta that enables businesses to sign up for the WhatsApp Business Platform directly through 360dialog. Rather than navigating multiple portals and completing manual verification steps, the entire process occurs within a single secure flow.
The Embedded Signup flow is primarily used to create WhatsApp Business Accounts (WABAs) and **register phone numbers** for use on the WhatsApp Business Platform.
{% hint style="info" %}
**Is the phone number already using the WhatsApp Business app?**
If the phone number is currently active on the WhatsApp Business App, a separate registration process via Embedded Signup is available. This process, called [Coexistence](https://docs.360dialog.com/docs/hub/embedded-signup/coexistence-onboarding), allows the number to be connected to both the WhatsApp Business Platform and the WhatsApp Business App at the same time.
If Coexistence is not required and the number should be registered exclusively on the WhatsApp Business Platform, proceed with the standard registration process below.

{% hint style="info" %}
**Is the phone number already on the WhatsApp Business Platform?**
If the number is already registered on the WhatsApp Business Platform through another Business Solution Provider, please review the available migration paths to transfer and register the number with 360dialog.
{% endhint %}
### **Prerequisites**
To launch the Embedded Signup flow and register a phone number, you must have the following:
* 360dialog Account
* A valid business [phone number](https://docs.360dialog.com/docs/resources/phone-numbers)
* Meta Business Portfolio
* While not an explicit requirement, we having a Meta Business Portfolio with the required permission before navigating the Embedded Signup Flow. It is possible to create a Business Portfolio using the ES flow, but it will take longer to get the required approvals before starting messaging.
* Ensure the [Business Info](https://www.facebook.com/business/help/257957338156440?id=180505742745347) section of the Meta business Portfolio is completed:
* Businesses must input their legal name, address, **website**, and business phone number in this page**.** Having an incomplete Business Info section with any of this information missing will trigger the WABA to be restricted, which may take some time.
* Live business website
* The Business website is reviewed by the WhatsApp Integrity team to ensure compliance with the WhatsApp Business Messaging Policy. To avoid immediate blocking, your website must:
* Be live and publicly accessible.
* Be secured with SSL (HTTPS).
* Clearly describe the company’s business.
### Embedded Signup Flow
Follow these steps to launch the Embedded Signup.
**Note:** The Embedded Signup uses Facebook Login, so only the owner or administrator of the Business Portfolio can start and complete the flow. Third-party providers are not allowed to navigate the Embedded Signup on behalf of the business.

## FAQ
Can I register a number that’s connected to an IVR system?
Yes, but the number **must be able to receive the WhatsApp verification code**.
WhatsApp only supports two verification methods:
* **Voice call** – An automated English call with a 6-digit PIN code.
* **SMS** – A text message with a 6-digit PIN (available only for mobile numbers or numbers that can receive SMS).
**Important:**
* The number must be able to receive **international calls or SMS**.
* Voice and SMS are the **only** supported registration methods.
* There are **no workarounds.**
What if my IVR system blocks the verification call?
You have two options:
**Option 1: Whitelist or Redirect Sender IDs**
If your IVR blocks incoming registration calls:
1. Contact Support to request the IVR Sender IDs (typically +1 US or +44 UK numbers).
2. Add these numbers to your IVR whitelist or redirect rules.
3. Capture the OTP when the call comes from one of these sender IDs.
**Option 2: Temporarily Disable IVR**
If possible:
1. Request a 15-minute registration window from Support.
2. Disable IVR during that time.
3. Receive the registration call directly.
I don’t receive the SMS or call, and no error appears. What should I do?
* Call the business phone number and ensure no IVR or redirect is happening
* Re-try the verification
* Try an alternate verification method
* Contact 360dialog Support
Why am I seeing a registration timeout?
Meta enforces cooldown limits during registration:
* You must wait 2 minutes between attempts.
* After 3 failed attempts, a 2-hour lock is automatically applied.
If you’re locked out, wait for the cooldown period before trying again.
Why can’t I select my Business Portfolio?
This usually happens if:
* You are not an **Admin** of the Business Portfolio.
* The Business Manager is restricted.
* The Business Manager hasn’t completed verification.
**How to fix it:**
* Confirm you have **Admin access** in Business Manager.
* Ask an existing Admin to grant you full permissions.
* Check if the Business Manager has any restrictions in Account Quality.
* Ensure business verification has been completed (if required).
You must use a Business Manager where you have full admin rights to complete Embedded Signup.
Why is my account under review after completing Embedded Signup?
After signup, Meta may automatically review:
* Your business information.
* Your website.
* Your display name.
* Commerce Policy compliance.
During review:
* Messaging may be limited.
* The account could appear temporarily restricted.
Check **Account Quality** in Business Manager for updates. If information is missing (especially website details), update it and request a review.
