WhatsApp Number Validator
Check phone numbers for WhatsApp-friendly international format. Paste one number or upload a CSV (first column = number). Export valid rows as CSV.
This tool checks format only (E.164-style, 8–15 digits with country code). It does not verify whether a number is registered on WhatsApp.
Single number
CSV upload
One number per line. Uses the first column if the line contains commas.
