Consolidator & Cross-Border Handoffs
Over 40% of e-commerce parcels—and nearly 100% of economy cross-border orders—change physical hands between an origin consolidator and a final-mile carrier. When you query only the final-mile carrier, your tracking UI shows "Shipping Label Created, USPS Currently Awaiting Package" or "We're expecting your parcel" for 3 to 10 days while the parcel is actively moving through middle-mile sort hubs.
lastscanned lets you query both the consolidator and the final-mile carrier synchronously via GET /v1/track/{number}?carrier={slug}.
Domestic USPS Consolidator Handoffs (926129… / 927489… / 93…)
USPS Electronic Verification System (eVS) and IMpb barcodes beginning with 92 (92001…, 926129…, 927489…) or 93 are shared barcodes. Because usps is checked first in auto-detection order, pass ?carrier= to query the middle-mile consolidator directly during transit:
