Cainiao tracking status codes explained

Tracking pages and API responses sometimes show raw codes such as GTMS_SIGNED or CC_IM_START. Here are the 115 codes listed in the official AliExpress tracking API, grouped by stage, with what each means and what to do.

Stages

How to read a code

The prefix is the stage: PU pickup, GWMS warehouse, SC sorting center, CC customs (EX export, IM import, TRANS transit country), LH the international leg, GTMS delivery in the destination country, GSTA and STA pickup points, RT returns.
SUCCESS, or no suffix, is a normal scan. FAILURE, FAIL, EXCEPTION or REJECT marks a problem at that stage.
Long gaps between scans are common on the international leg and in customs. A FAILURE code matters more than a quiet stretch.

CONSIGN, OM, ASN

Shipment created

The seller has created the shipment and sent its details. The parcel may not be handed over yet; if nothing else appears for several days, ask the seller.

Code	Meaning
`CONSIGN`	Shipment declared
`OM_CONSIGN`	Shipped by seller
`GTMS_ASN`	Electronic shipment notice received

Pickup

The parcel is being collected from the seller. A FAILURE code means the pickup did not happen; ask the seller to arrange it again.

Code	Meaning
`PU_PICKUP_SUCCESS`	Picked up
`PU_PICKUP_FAILURE`	Pickup exception
`PU_SIGN_IN_SUCCESS`	Received at collection point
`PU_SIGN_IN_FAILURE`	Collection point receipt exception

GWMS

Warehouse

Scans from the warehouse handling the order: accepted, picked, packed and shipped out. GWMS_REJECT or GWMS_EXCEPTION means the warehouse hit a problem; contact the seller or Cainiao support.

`CC_EX_FAILURE`	Export customs clearance exception

Codes that name a shipping service

Strings that start with CAINIAO_, such as CAINIAO_STANDARD_HEAVY, are AliExpress logistics line codes. They name the shipping service, not where the parcel is. AliExpress's API documentation shows, for example, CAINIAO_OVERSEA_STD_SERVICE_ES displayed as “Euro-business Parcel”. If a line code is unclear, ask the seller which service it is.

Sources

Codes and their Chinese descriptions come from the action_code field of the AliExpress Open Platform tracking API (aliexpress.logistics.redefining.querytrackingresult), read on November 4, 2026. The documentation presents them as examples, so a code not listed here can still appear. Translations and the advice for each stage are this site's.
