A1 Post Tracking. Free & Online.

A1 Post is a Bulgarian cross-border shipping company that sends ecommerce parcels from Bulgaria to customers worldwide. It works mainly with online sellers and connects to marketplaces and shop platforms such as Etsy, Amazon, eBay, Shopify and WooCommerce, so most people meet it as the shipper named in an order confirmation. A1 Post collects the parcel from the seller, exports it, and hands it to a postal or courier partner in the destination country for delivery. Its tracking is a simple list: each line has a date and time and one sentence describing what happened. There are no status codes to decode, and TrackParcel shows the lines as A1 Post writes them, newest first.

A1 Post tracking begins with the reference printed on the shipment label, booking receipt, or dispatch message. The registered format guidance for this integration is The A1 Post tracking number from the seller's shipping message; M1234567890 is an illustrative example rather than an active parcel. Enter the reference exactly as issued, including letters, leading zeroes, spaces, or punctuation when they form part of the number.

TrackParcel sends the lookup to the public tracking transport associated with A1 Post and normalises the response into a readable timeline. When the carrier supplies them, the result can include the current shipment state, event timestamps, processing locations, and carrier remarks. The carrier creates and controls those scans; TrackParcel cannot add a missing event or promise when the next scan will appear. A recent successful response may be returned from a short-lived cache to reduce repeat requests.

A1 Post uses its own shipment references and scan process. The safest source is the dispatch confirmation, label, or receipt issued for that shipment. Similar-looking numeric references can belong to other couriers, so selecting A1 Post explicitly avoids an ambiguous format match.

If A1 Post returns no shipment, first compare the reference with the original message and remove accidental surrounding spaces. A newly created label may not be searchable until the first physical scan. Delays between events can also occur while a shipment moves between facilities, crosses a border, clears customs, or waits for a partner-carrier handoff. Try again later, then use the official A1 Post tracking page linked below when the shipment is urgent or the result remains unavailable.
