Frequently Asked Questions
Find clear answers for tracking scan gaps, customs delays, carrier handoffs, and parcel visibility questions.
Which carriers are supported on 9Tracking?
Carriers
9Tracking supports major postal and express carriers across multiple countries. The system attempts to auto-detect the carrier from the tracking number format and route behavior.
Can one tracking number change carriers during delivery?
Carriers
Yes. Cross-border shipments often move between an origin carrier, an airline or line-haul partner, customs processing, and a destination last-mile carrier. 9Tracking groups these handoffs into one timeline whenever the providers expose enough tracking data.
