Why is my WhatsApp Business verification code not arriving?

Wait for the timer to finish, then ask for a phone call: an automated voice reads the six-digit code aloud. Enter your full international number, because VoIP and toll-free numbers cannot be registered.

• Enter the full international number with country code and no leading zeros or exit codes.
• Check mobile data or Wi-Fi, and turn off call-blocking apps and task killers.
• VoIP, toll-free, paid premium and universal access numbers cannot be registered.
• Wrong codes entered again and again can lock you out. You must wait the stated time, and it cannot be sped up.
