There are many types of accounts that allow a customer to retrieve his account balance over the phone. Cell phone, bank, credit card and gift card account balances are a few of the various balances that can be obtained over the phone.
Many companies that offer balance inquiries over the phone provide a phone number to reach an automated service to provide the balance. The customer is then required to enter specific account information and prove his identity. Cell phone providers often have a speed dial or text option, such as #bal, pre-programmed into the phone to enable quick balance retrieval.
