Quick checks, in order
Verify the full international number
Select the correct country and enter the number without an extra leading zero where applicable.
Confirm the SIM works
Ask someone to call and text the same number.
Wait for the timer
Do not repeatedly request codes while the on-screen timer is active.
Try the call option
Use the automated voice call only when WhatsApp offers it.
Where is the verification failing?
Check number formatting, signal, blocked senders, spam filtering, and carrier restrictions.
Complete verification on the new phone using the code sent to the registered number; linked-device prompts are not a replacement for number verification.
Stop requesting codes and wait for the displayed period. Repeated attempts can extend the delay.

Frequently asked questions
Can WhatsApp send the code by email?
Phone-number verification normally uses SMS or an automated call. Do not trust unofficial code-delivery offers.
Should I share the code with support?
No. Verification codes should never be shared with another person.
