The rule for Italy

Italy is the common exception to the drop-the-zero rule — but only for landlines, which keep their leading 0 even internationally. Italian mobile numbers never had one to begin with, so they pass through unchanged. Do not add a 0 to an Italian mobile.

  1. Start with the local number. 312 345 6789
  2. Apply the Italian rule. There is no prefix to remove, so the digits stay as they are.
  3. Add the country code. Put 39 in front, giving 393123456789.
  4. Build the link. Append the digits to https://wa.me/ with nothing between them, or use the generator and let it handle the formatting.

Does a valid number mean the person is on WhatsApp?

No. Everything above concerns format, which is a separate question from whether an account exists. A correctly formatted Italian number can belong to a landline, to a newly issued SIM, or to someone who has deleted their WhatsApp account, and in each case the link will open and report that the number is not on WhatsApp.

To find out, open a chat link for the number and see whether WhatsApp starts a conversation.

How do I write an Italian number for WhatsApp?
