WhatsApp verification code not arriving
WhatsApp's SMS flow fails in a handful of known ways, each with a different fix.

Why is my WhatsApp code not coming?
Most often because WhatsApp silently refuses the number range (VoIP or over-used prefix) while still showing the timer. Wait two minutes, then cancel the number in your dashboard (not charged), take one from a physical-SIM country with a high success rate for WhatsApp, and request the SMS once.
The five cases
- Timer runs, nothing arrives: WhatsApp dropped the number range. Change country.
- 'Wait 1 hour before requesting': you hit the resend limit. Use a different number.
- Code arrives but 'invalid': you typed an old code; use the latest SMS.
- Number marked 'not valid': VoIP rejection; physical SIM needed.
- Call verification offered: SMS Nitro numbers receive SMS only; stick with SMS.
Countries with the best WhatsApp rates
Indonesia, the Philippines, the UK and several EU countries lead most weeks in the catalog; the WhatsApp page shows the live ranking.

Frequently asked questions
Do I pay for the number that received nothing?
No. Cancel it or let it expire; the amount returns to your balance.
Can I get the WhatsApp code by call instead?
Not on SMS Nitro numbers; choose SMS. If WhatsApp only offers a call, take another number.
Why does WhatsApp say 'wait 1 hour'?
You requested the code too many times. Use a different number rather than waiting.
Is the failed number charged?
No. Cancel it or let it expire and the amount returns to your balance.
