AWB and LRN

Bigship uses two types of tracking identifiers depending on the shipment category: AWB for B2C and LRN for B2B.

AWB (Air Waybill)

An AWB is the tracking number assigned to B2C shipments after manifestation. It uniquely identifies a parcel in the courier’s network and is used for tracking and label generation.

const manifest = await client.manifestSingle({ order_id: 'ORD-123' });
const awb = await client.getAWB({ order_id: 'ORD-123' });

// Track by AWB
const tracking = await client.trackShipment(awb.data, 'awb');

LRN (Lorry Receipt Number)

An LRN is the tracking number assigned to B2B shipments after manifestation. It serves the same purpose as an AWB but for heavy/bulk shipments transported by road.

const manifest = await client.manifestHeavy({ order_id: 'ORD-456' });

// Track by LRN
const tracking = await client.trackShipment('LRN-789', 'lrn');

Comparison

Aspect	AWB	LRN
Shipment type	B2C	B2B
Assigned by	manifestSingle	manifestHeavy
Retrieve with	getAWB	getShipmentData
Track with	trackShipment(id, 'awb')	trackShipment(id, 'lrn')
Transport mode	Air / surface (last-mile)	Road (heavy freight)

Tracking

The trackShipment method accepts the identifier type as its second argument:

// B2C tracking
const b2cStatus = await client.trackShipment('1234567890', 'awb');

// B2B tracking
const b2bStatus = await client.trackShipment('LRN-789', 'lrn');

Passing the wrong type will result in a tracking error — always match the identifier to the shipment category.
