How do I activate my card online?

The specific requirements to activate a credit card online vary by provider, but the first step is to follow a card activation link or phone number normally provided on a sticker on the card, according to CreditCards.com. Banks often allow the option to activate through an existing online bank account.

Discover allows users to activate new cards by logging into their Discover accounts or by entering personal details as guests, such as birthdates, Social Security numbers and card numbers. Bank of America also indicates on its website that new cardholders can log in and verify account information or register for a new account before verifying.
