Overview

Check whether authorized contact numbers are available on WhatsApp.

TheDualWeb helps teams check contact-number availability before reaching out. Features: - Pair an authorized WhatsApp device using a time-limited QR code. - Enter authorized phone numbers directly. - Select a local TXT or single-column CSV file with one number per line. - Review availability results inside the extension. - Disconnect the paired session at any time. Submitted numbers are sent to TheDualWeb's API only when you start a check. Selected files are read and validated locally; file contents and file names are not uploaded. Pairing and session credentials are stored in browser local storage so the authorized connection can continue across extension openings. Only check numbers you own or have permission to contact. TheDualWeb is not affiliated with, endorsed by, or sponsored by WhatsApp or Meta.
