Whatsapp Support wroteHi,
Sorry to hear you are having problems verifying. First, try the "Call Me" button.
If that doesn't work, please follow these steps to get your verification code:
1. Delete the WhatsApp application from your iPhone by tapping and holding the WhatsApp icon
until it vibrates. Then, select the WhatsApp icon again to delete. (NOTE your messages will also
be deleted when you delete WhatsApp).
2. Reboot your iPhone: turn your iPhone OFF, wait 30 seconds, turn it back ON
3. Download a fresh copy of version 2.6.10 by opening the
http://itunes.com/app/whatsapp link
from your iPhone (NOTE: you will NOT get charged again if you use the same iTunes account
as iTunes is pretty smart - we promise:)
If you don't get your code, please wait for the 5 minute verification process to end. Then you can use the fallback option "Call Me".
If you are not using an iPhone, please follow these steps to get your code:
1) Delete WhatsApp
2) Reboot your phone (turn off the phone, take out battery if possible. Wait 30 seconds. Then put back the battery and turn your phone on)
3) Download a new version of WhatsApp:

Please note that we cannot send you a code via email.
Please be aware that BlackBerry users must have a full BIS (BlackBerry Internet Service) plan to use WhatsApp. Nokia users must have a data plan with no restrictions or blocks.
