# Why did verifying my WhatsApp number fail?

> What to do if verifying a WhatsApp number for on-call notifications fails.

Most of the time this is a quick fix. Try these steps in order before getting in touch.

1. **Update to the latest version of WhatsApp.** Most verification failures come from an out-of-date app. Update WhatsApp from the [App Store](https://apps.apple.com/app/whatsapp-messenger/id310633997) or [Google Play](https://play.google.com/store/apps/details?id=com.whatsapp), reopen it, and try verifying again.

2. **Check we can message each other.** If you're on the latest version and it still won't verify, send a hello message to **+44 7576 586600** on WhatsApp. This confirms WhatsApp will let our number reach you.

If you've done both and still can't receive a verification message, [reach out to us](mailto:support@incident.io) and we'll take a look.
