Quick answer

It depends mostly on Meta's reviews

Meta does not publish one total setup time. The times it does publish: business verification — a decision can take up to 14 business days; message templates — review can take up to 24 hours; higher messaging limits — up one step within 6 hours once you qualify. You can start messaging within the starting limits before verification is finished. Our team helps you through each step for free.

Stage by stage

The six stages of setup and how long each takes

Times below are only what Meta officially states. Where Meta gives no time, we say so.

Connect through Meta's Embedded Signup

On the Lead Pattern Home dashboard, choose Connect with WhatsApp. A Meta pop-up opens where you log in with Facebook and pick or create your business portfolio and WhatsApp Business Account. Time: varies — Meta doesn't publish a fixed time.

Add and verify your phone number

Enter the number and type in the code Meta sends by SMS or voice call. Time: varies — Meta doesn't publish a fixed time.

Display name review

Meta checks the business name customers will see. Its status shows as pending review, approved or declined. Time: varies — Meta doesn't publish a fixed time.

Business verification

You submit your legal business details in Meta Business Suite. Meta says a decision can take up to 14 business days. You can start messaging within the starting limits while you wait.

First template approval

Submit your first message template. Meta says review can take up to 24 hours, and an appeal is decided within 24 hours.

Messaging limit increases

New business portfolios start at 250 customers a day. After you verify, Meta raises the limit to 2,000 straight away once your quality passes review. Higher steps come within 6 hours when the rules are met.

What makes setup faster

Keep your business details ready. Business verification usually takes the longest. Meta asks for your legal business details and, if it can't match them to a record, documents such as a business licence. If you change the details later, you have to verify again. Documents you need →
Use a number that is ready. It must be a number you own that can receive an SMS or a voice call. A number active on WhatsApp must be deleted from the app first — or, if it is on the WhatsApp Business app, connect it with *Connect Existing WhatsApp Business App*. Which number to use →
Choose a display name that matches your business. A declined name can be edited and resubmitted, but each change goes back for review. Number and name errors →
Write templates that follow Meta's rules. A clear category and real sample values avoid a rejection and a second wait. Why templates get rejected →

How messaging limits grow

Meta limits how many different customers your business can start conversations with in a moving 24-hour period. Limits are set for your whole business portfolio, so all your numbers share one limit. The steps are 250, 2,000, 10,000, 100,000 and unlimited.

To reach 2,000 you verify your business — or deliver 2,000 high-quality template messages to different customers in 30 days. Meta then checks your quality and raises the limit straight away if it is approved. After that, your limit goes up one step within 6 hours when your messages are high quality and you used at least half of your current limit in the last 7 days. Messaging limits explained →
