# How to Connect Your Number to ChatSyncs
> The easiest way to connect a phone number to ChatSyncs — Embedded Signup turns any number into a WhatsApp Business number automatically, with no technical setup needed.
**First, pick your path:**
* If you want to keep using WhatsApp on your phone (the Business App) **and** ChatSyncs at the
same time, see [How to Connect Your WhatsApp Business App
to ChatSyncs](/learn/chatsyncs-overview/connect-your-whatsapp-business-app-to-chatsyncs) instead.
* If your number is already active on the WhatsApp app and you want to move it onto ChatSyncs
instead of keeping both, see [How to Migrate from WhatsApp App to a ChatSyncs Business
Account](/learn/chatsyncs-setup-and-configuration/migrate-from-whatsapp-app-to-a-chatsyncs-business-account) instead.
* If you want a brand-new number used **only** on ChatSyncs, not on your phone, keep reading —
this page covers that path.
## Before you start
* A Facebook account with access to the business.
* A phone number not already active on WhatsApp or WhatsApp Business (if it was, delete that number from WhatsApp permanently and wait a few hours first).
* A **Meta Business Portfolio** — the account container that holds your business's WhatsApp setup. Embedded signup can create one for you on the spot if you don't have one yet (just a name, your first/last name, and a website).
## Connect a brand-new number (Cloud API)
Go to **Connect Account**, under **Business Accounts** click **Connect WhatsApp**, then pick the green **Embedded Onboarding (One Click)** card and click **Connect with Embed Onboarding** (the blue **Create Your Own API Connection** card is the manual path — see [How to Connect Your WhatsApp Account Manually (Alternative Method)](/learn/chatsyncs-setup-and-configuration/connect-your-whatsapp-account-manually-alternative-method-in-chatsyncs)).
If you've already set up a product catalog and want to share its permissions, click **Connect With Catalog** — otherwise click **Connect Without Catalog**. Either opens Meta's popup.
Meta's popup opens. Log in if you aren't already, then click **Continue**.
Pick an existing portfolio from the dropdown, or click **Create a Business Portfolio** if you don't have one — it only asks for a portfolio name, your first/last name, and a website.
With the portfolio selected, open the **WhatsApp Business account** dropdown — you'll see two options:
* **Create a WhatsApp Business account** (first option) → a brand-new number, usable only on ChatSyncs, not on your phone. **Pick this one.**
* **Connect a WhatsApp Business App** (second option) → this is the [How to Connect Your WhatsApp Business App to ChatSyncs](/learn/chatsyncs-overview/connect-your-whatsapp-business-app-to-chatsyncs) path instead, for keeping a number on your phone too — don't pick this here.
Any number shown crossed out is already connected somewhere else and can't be picked.
Click **Next**, then fill in the **Name**, **Category**, and **Website** for the new asset (Country and Time zone are carried over from your portfolio).
Choose **Add a new number** (the alternative, **Use a display name only**, uses a shared Meta test number where people only ever see your display name — not a real number).
Enter your country and **phone number**, then the **WhatsApp Business display name** — this is what customers see at the top of the chat on every message, so get it right. Choose **Text message** or **Phone call** to receive your verification code, click **Next**, then enter the code you receive.
Meta confirms the connection — click **Finish** to return to ChatSyncs, where the number shows up under your connected Business Accounts.
Once a number is connected via Cloud API, it can no longer be used in the standard WhatsApp or WhatsApp Business app on a phone. Use a dedicated business number — or use [How to Connect Your WhatsApp Business App to ChatSyncs](/learn/chatsyncs-overview/connect-your-whatsapp-business-app-to-chatsyncs) instead if you need to keep using the app.
## Frequently asked
**Cloud API** connects a brand-new virtual number dedicated to ChatSyncs — once connected, that number can't be used in the regular WhatsApp app anymore. **Coexistence** links your *existing* WhatsApp Business App number instead, so you keep using the app on your phone while ChatSyncs automates on the same number. See [How to Connect Your WhatsApp Business App to ChatSyncs](/learn/chatsyncs-overview/connect-your-whatsapp-business-app-to-chatsyncs) for that path.
Your number is already linked to a different platform/partner. See [How to Disconnect Another Partner From Your WhatsApp Number](/learn/chatsyncs-setup-and-configuration/disconnect-another-partner-from-your-whatsapp-number-in-chatsyncs) for the full steps, then re-enter your number.
No — embedded signup can create one for you inline during the flow. It only asks for a portfolio name, your first/last name, and a website. See [How to Create a Facebook Business Manager Account for ChatSyncs](/learn/chatsyncs-setup-and-configuration/create-a-facebook-business-manager-account-for-chatsyncs) if you'd rather set it up ahead of time.
Use [How to Connect Your WhatsApp Account Manually (Alternative Method)](/learn/chatsyncs-setup-and-configuration/connect-your-whatsapp-account-manually-alternative-method-in-chatsyncs) instead — it takes more steps but gives full visibility into every credential.
