The US Postal Service is testing an electronic notification system that would allow customers to receive images of their mail every morning:
Participate in this new USPS service enhancement test and get images of the mail that will be placed in your mailbox each day. Black and white images of your actual letter-sized mail pieces, processed by USPS sorting equipment, will be provided to you each morning. Flat-sized pieces, such as catalogues or magazines, may be added in the future.
In the Fall of 2015 the service will be available in the New York City metro area, including the following three digit zip code locations: NY: 100-119; CT: 066 & 069. The service has been available in select zip code locations in Northern Virginia since 2014 starting with the following three digits: 201, 220, 221, 222, 223, 226, 227. Expansion to other areas is being considered for 2016.
