Choose the country first. Numbers that start with + are read with their own country code.

- Adding spaces or brackets inside the country code: write +91, not +9 1.
Frequently asked questions
What is E.164?
E.164 is the international format: a plus sign, the country code and the number with no spaces, for example +447700900123. Apps and APIs usually want this form.
Which Indian numbers are valid?
Mobile numbers have 10 digits and start with 6, 7, 8 or 9. A leading 0 or +91 is accepted.
How is the WhatsApp link made?
The link is https://wa.me/ followed by the E.164 number without the plus sign.
Is anything uploaded?
No. This tool runs in your browser and nothing you enter is sent to a server.
