A system and method is provided for transmitting mail verification data over a wide area network, such as the Internet, in response to receiving and authenticating at least a portion of mail identification (ID) data. In one embodiment of the present invention, a mail verification application is adapted to store at least a verifying portion (e.g., an identifiable code portion, a shipping portion, a recipient portion, etc.) of mail ID data in memory. The mail ID data is then affixed to a mail object. The mail object is then manually delivered to a recipient. At least an authenticating portion of the mail ID data is then provided to a reception device. The reception device, which communicates with the mail ID device over a wide area network, transmits at least the authenticating portion of the mail ID data to the mail verification application operating on the mail ID device. The mail verification application then compares the authenticating portion of the mail ID data with the verifying portion stored in memory. If the authenticating portion of the mail ID data is authenticated, mail verification data is sent to the reception device. In one embodiment of the present invention, at least a portion of the mail verification data includes authenticating data, securing data, sender data, recipient data, mail-content data, downloadable-product data, sender-web-page data, and/or third-party-web-page data.
