Tool to verify the existence of a phone number on Whatsapp. Updated and optimized version for checking large list of numbers without ban(Checked with 2500 numbers ≈ 12hrs).

Uses Whatsapp Web to verify if the number has an associated Whatsapp account without sending a message.

1. Install dependencies

npm run bootstrap

2. Login (All user data is stored only in project folder './profileData')

npm run login

Check one Phone Number:

npm run check 919898989898

Check large list of numbers:

Place your list in src/numbers/txt.

Note Each number must be on a new line. There are two acceptable formats:

919898989898
919398489898
919892349898

OR

Adam Smith: +38(055)333-22-22
James Brows: 919398489898
Neo: +919892349898

Run check script:

npm run check:list

Note You can specify number length in 'utils/checkNumberBulk.js line 20'.

Note If process was failed for some reasons - the last checked number index will be loged in console. You can use it to set start position for the next check to skip already validated numbers.

 const VS = new WhatsAppVerificationService(browser, {
      currentPosition: 0, // Start position
      validateLength: 11, // Required number length
    });

Note You can find all results in 'logs' folder.

• "logs.txt" is a log file.
• "tempResults.json" updating every successful check. Can be used to retrieve results when the process is not finished or exited with an error.
• "results.json" final results with only valid numbers.

Caution Using method to verify numbers in bulk can result in the logged in number being banned by WhatsApp
