Feature Guide: WhatsApp Number Validator

Welcome to WA Work Flow! We’re excited to introduce one of our most powerful and time-saving tools — the WhatsApp Number Validator.

This new feature allows you to check whether a phone number is valid and available on WhatsApp before you send a broadcast message. It ensures your campaigns are more accurate, efficient, and cost-effective.


🔧 Step-by-Step Guide

Step 1:

Open the WA Work Flow Extension.

Step 2:

Go to the Advanced Feature section. A pop-up window will appear.

Step 3:

Click on WhatsApp Number Validator from the pop-up menu.


Step 4:

You’ll now see an option to upload an Excel file containing the phone numbers you want to validate.

Right below that, you’ll also find a link labeled “Excel (sample)” — click it to download a sample format. This sample will help you correctly organize your numbers for validation.


Step 5:

After preparing your Excel file, upload it into the validator. Then click on “Validate & Download.” The system will begin processing and verifying your numbers.


📊 After Validation

Once the validation is complete, your report file will be downloaded automatically. This report will clearly show: ✅ Valid numbers available on WhatsApp ❌ Invalid or inactive numbers


⚙️ Performance Tip

To get the best speed and accuracy:

  • Validate small batches of 400–500 numbers for faster results (within minutes).

  • If you upload 1,000–3,000 numbers, processing may take 1–3 hours, depending on system load and network speed.


💡 Benefits of Using WhatsApp Number Validator

  • Save Time: Avoid sending messages to inactive or invalid numbers.

  • Save Cost: Reduce wasted message credits on unreachable users.

  • Improve Accuracy: Ensure all messages reach genuine WhatsApp users.
