As of October 31, 2026, the United States Postal Service discontinued the printing and distribution of several tracking labels, 888, 889, 891, and 892. Legacy tracking and special-service labels added after postage-meter processing are being phased out because the tracking number is not electronically linked to the delivery address. These legacy labels are incompatible with updated processing equipment. Electronic labels improve tracking visibility and processing. Integrated labels combine address, postage, and barcode. Tracking, Signature Confirmation, and insurance remain available.
