WhatsApp username checker
Type a handle to check it against WhatsApp’s username format rules, and see whether it is currently listed for sale on wausernames. We cannot query WhatsApp for availability — there is no public API — so a “not listed” result means it is not on this marketplace, not that WhatsApp has it free.
Format: 3-30 characters, lowercase letters + digits + . _, must contain a letter.
