USPS Informed Visibility® Mail Tracking

LetterTrack makes USPS Informed Visibility Mail Tracking available for small to mid-sized companies sending mass letter mailings and online sellers shipping items in letter sized envelopes, flat sized envelopes, and bubble mailers. This provides the ability to track first class mail via our cloud software.  LetterTrack adds a USPS intelligent mail barcode above the address block of the recipient on your mailpiece. As your mail travels through the postal system to its destination, the intelligent mail barcodes on your mailpieces are scanned at each facility. When a mailpiece reaches the destination post office to be placed on a USPS postal truck for delivery, the mailpiece is marked as Out for Delivery.

Searchable tracking screen
