California Civil Code
(a) A credit card issuer that mails an offer or solicitation to receive a credit card and, in response, receives a completed application for a credit card that lists an address that is different from the address on the offer or solicitation shall verify the change of address by contacting the person to whom the solicitation or offer was mailed.
(b) Notwithstanding any other provision of law, a person to whom an offer or solicitation to receive a credit card is made shall not be liable for the unauthorized use of a credit card issued in response to that offer or solicitation if the credit card issuer does not verify the change of address pursuant to subdivision (a) prior to the issuance of the credit card, unless the credit card issuer proves that this person actually incurred the charge on the credit card.
(c) When a credit card issuer receives a written or oral request for a change of the cardholder’s billing address and then receives a written or oral request for an additional credit card within 10 days after the requested address change, the credit card issuer shall not mail the requested additional credit card to the new address or, alternatively, activate the requested additional credit card, unless the credit card issuer has verified the change of address.
(d) This section shall become operative on July 1, 2000.
