What format does WhatsApp need?

Country code followed by the number, with no spaces, dashes, brackets or leading zero – for example 919876543210.

What happens to numbers that already have a country code?

If a number is longer than 10 digits and starts with your country code, it is kept as it is.

A full number with country code should have 8 to 15 digits. Shorter or longer entries are listed separately so you can check them.

No. Everything happens in your browser. Nothing is sent to a server.
