What is my self service password?
Your self service PIN is the last 4 digits of your customer number, unless you've changed it. You can find your customer number on any of your Vodafone bills.
If you don't know your customer number or have access to a previous bill, you can use the Forgot your PIN link to send it to your mobile.
If you're on a business account and not the account contact you won't be able to use this service. You should contact your Vodafone account manager for more information.
