What is an A1 Express Tracking Number?
An A1 Express tracking number is a unique alphanumeric identifier assigned to every parcel processed through the A1 Express / Asendia USA network. This code ties your shipment to its electronic record in the carrier's system, allowing you and the recipient to monitor the parcel's journey from pickup through final delivery. A1 Express is a cross-border postal and e-commerce delivery service operated by Asendia USA, a joint venture between La Poste (France) and Swiss Post, focused primarily on lightweight international parcels and direct mail flowing into the United States.
Your A1 Express tracking number appears in several places. If you purchased goods online, the retailer or marketplace will include the tracking number in the shipping confirmation email. It is also printed on the physical label affixed to your parcel. Merchants who use Asendia USA's platform can find all tracking numbers inside their Asendia USA shipper portal. Third-party tracking aggregators such as 17TRACK and AfterShip also accept A1 Express tracking numbers if you prefer a single dashboard for multiple carriers.
A1 Express tracking numbers are typically 8 to 13 alphanumeric characters. Common formats include a two-letter prefix (indicating service type or origin) followed by nine digits and a two-letter country suffix — for example, US123456789US. Some domestic labels may use purely numeric strings of 10 to 12 digits. Because A1 Express / Asendia USA handles a variety of product lines (ePacket, economy air, tracked letter post), the exact format varies by service tier. When in doubt, enter your full tracking code at a1.asendiausa.com/tracking to verify it is recognized.
Common A1 Express Tracking Statuses and Their Meanings
| Original Status | Translated Status | Description | Action Required |

| Accepted / Picked Up | The parcel has been collected from the sender or dropped off at an A1 Express facility and scanned for the first time. | None. Your package is now in the system. | |
| In Transit | The shipment is actively moving between A1 Express / Asendia USA hubs or between the origin country and the destination country. | None. Monitor for updates. | |
