Important Notes:

Carnival advises that the emergency contact number (1-855-732-4023) is strictly for true family emergencies.
The standard customer service line (855-732-4023) has limited hours.
If you're calling about an upcoming cruise and it's urgent, you can call 1-855-732-4023 ext. 80062 during regular business hours.
If you've already sailed and have urgent post-cruise questions, it's best to use the appropriate contact method mentioned in the search results, such as the post-cruise inquiries page.
Carnival does not offer a direct dialing service to their ships, so the emergency contact numbers are for shore-to-ship communication 44-289-708-0062.
