The Postal Service has extended the cut-off date to support Confirm-based Pre-shipment Notification, (Electronic Mailing Data or EMD files) from March 14th to May 14th, 2010.
After May 14th, the USPS plans that EMD files will no longer be used, and Intelligent Mail Full-Service "Start the Clock" or Facility Access and Shipment Tracking (FAST) system appointment closeout information for shipments will be used instead.
In the time between March 14th and May 14th, the Postal Service is planning to conduct a series of webinars to inform customers how to utilize FAST to create appointments and to obtain appointment closeout information for shipments.
To contact the USPS concerning the webinars, email confirm@usps.gov
