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.
Open the WA Work Flow Extension.
Go to the Advanced Feature section. A pop-up window will appear.
Click on WhatsApp Number Validator from the pop-up menu.
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.
After preparing your Excel file, upload it into the validator. Then click on “Validate & Download.” The system will begin processing and verifying your numbers.
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
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.
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.
Boost Performance: Clean your contact list before broadcasting.
