WhatsApp finally begins rolling out username support

WhatsApp has started a phased rollout of username support, making the feature available to some users.

Users can create a new username or import their Facebook or Instagram username from Settings.

Usernames must be 3–30 characters, include at least one letter, and use only lowercase letters, numbers, periods, and underscores.

Created usernames can be shared instead of phone numbers when exchanging contact details.
