Quick Answer
Use the shipment or waybill number supplied by the seller or GSC, then try it in 17TRACK. Check the underlying express carrier named on the label before treating a result as a GSC scan. An order number, invoice number or merchant reference usually cannot replace a shipment identifier. 17TRACK is an independent tracking platform and does not transport parcels, change addresses, issue refunds or approve claims.
How to Track GSC Packages
Start with the number on the freight receipt, shipping label or seller’s dispatch message. Because GSC is a forwarding agency, the number may belong to an underlying express, postal or airline-linked service rather than to GSC itself.
| Route | Action |
|---|---|
| Official GSC route | Contact GSC using the published phone number and provide the shipment number, origin, destination, shipping date and seller reference. |
| 17TRACK route | Enter the complete shipment number in 17TRACK and allow carrier auto-detection; try the named UPS, DHL, FedEx, USPS or EMS service separately when the number identifies that operator. |
| No result | Recheck letters and digits, remove accidental punctuation, confirm that the label has been physically handed over, and ask the seller or GSC which partner issued the number. |
Tracking Number Formats and Examples
GSC’s official company profile does not publish one universal tracking-number grammar. The practical identifier is therefore service-specific. A partner-issued number can be visible in GSC communications without being issued by GSC.

Tracking Statuses and Meanings
| Status | What it means |
|---|---|
| Shipment information received | A booking or label record exists; physical acceptance has not necessarily occurred. |
| Accepted / picked up | A named transport operator has recorded possession or an acceptance scan. |
| In transit | The shipment is moving between facilities or transport legs. |
| Customs processing | Documents or goods are being reviewed; arrival at customs is not proof of release. |
| Out for delivery | The destination delivery operator has assigned the shipment to a delivery route. |
| Delivered / exception / returned | Check the delivery evidence or exception instruction; the shipper should begin a carrier inquiry when the parcel cannot be located. |
Services and Delivery Times
GSC lists international express, air freight, ocean freight, land transport, import logistics, FBA lines, sensitive-cargo transport and Europe/Americas small-parcel solutions. The supplied official pages do not publish route-by-route delivery standards, so a quoted transit time must be checked against the selected service, origin, destination and handoff plan.
Service Comparison
| Service | Best fit |
|---|---|
| International express | Time-sensitive documents and parcels arranged through an express partner. |
| International air freight | Commercial cargo requiring air transport and forwarding coordination. |
| International ocean freight | Larger or less time-sensitive consignments. |
| FBA and small-parcel lines | E-commerce replenishment and cross-border parcel programs. |
Delivery Time
| Service | Published delivery information |
|---|---|
| International services | Route-specific timing is quoted according to origin, destination, mode, customs and partner selection; the supplied pages do not state a universal day count or money-back guarantee. |
| Promotional routes | News pages mention United States, Australia and Europe route promotions, but do not establish a general delivery commitment. |
Destination Country Delivery Times
| Destination region | Planning guidance |
|---|---|
| United States | GSC publishes a United States line promotion, but the supplied official material does not state a destination-specific delivery range, average or named last-mile carrier. |
| Australia | GSC publishes an Australia line promotion, but the supplied official material does not state a destination-specific delivery range, average or named last-mile carrier. |
| Europe | GSC publishes a Europe truck-delivery promotion, but the supplied official material does not state country-level delivery ranges, averages or customs thresholds. |
| Other international destinations | Request a route quotation before dispatch; timing depends on mode, handoff, customs and final-mile arrangements. |
An estimated delivery window is a planning estimate, not a guarantee. Customs review, peak demand, weather, address quality, remote-area delivery and missing handoff scans can extend the visible transit period.
Common Tracking Problems and Solutions
| Problem or status | First action |
|---|---|
| Invalid number | Compare the label with the seller message and ask which partner issued the number. |
| No events | A label or booking may exist before physical acceptance; ask the shipper to verify handoff. |
| Long gap in transit | Check customs, line-haul and partner handoff; the shipper should request an inquiry from GSC or the issuing carrier. |
| Delivery exception or address issue | Use the destination carrier shown in tracking and contact the seller promptly; do not assume GSC can change the address. |
| Delivered but missing | Check the entrance, reception desk, neighbors and delivery evidence, then contact the local carrier and seller. |
| Lost or damaged | The shipper should preserve packaging, photographs, invoice and value evidence and ask GSC which underlying carrier claim process applies. |
International Shipping, Customs and Carrier Handoffs
GSC’s international forwarding role can connect an origin pickup, export processing, line-haul, customs handling and destination delivery partner. An electronic pre-alert is not the same as physical possession, and arrival at customs is not customs release.
| Stage | Tracking interpretation |
|---|---|
| Origin pickup and export preparation | GSC or an appointed origin operator receives shipment data and prepares consolidation, documents and transport. |
| Export customs and security | Authorities or handling facilities review export documentation; the number may remain unchanged. |
| Line-haul | Air, ocean or land transport occurs, often with fewer public scans. |
| Destination customs and handoff | The destination authority and appointed carrier handle import requirements and last-mile acceptance. |
| Final delivery | The destination delivery operator records delivery, pickup, exception or return events. |
Lost, Damaged, Claims and Refunds
| Process | Use when |
|---|---|
| Tracking inquiry | Events are missing or contradictory; provide the shipment number and recent scan. |
| Carrier investigation or claim | The shipper needs a formal loss or damage review; eligibility, filing window and compensation depend on the underlying service contract. |
| Seller refund | A buyer seeks commercial reimbursement; the seller or marketplace controls that decision, not 17TRACK. |
The shipper should retain the label, packaging, contents photographs, invoice and proof of value. Ask GSC whether the claim must be filed with GSC or with the partner whose waybill records the shipment.
Shipping Restrictions and Special Handling
| Category | Operational guidance |
|---|---|
| Dangerous or sensitive goods | Declare goods before booking and obtain route-specific acceptance guidance; air and express restrictions can differ. |
| Batteries, liquids and perishables | Packaging, documentation and destination rules may affect acceptance, routing and customs processing. |
| Prohibited imports | Check the current GSC quotation and destination-country rules before payment or dispatch. |
Customer Service
| Channel | Verified contact |
|---|---|
| Telephone | 020-86263835; the supplied official pages do not state business hours or time zone. |
| Official website | GSC contact page; use it for business, service and complaint routing. |
| Information to prepare | Shipment or waybill number, sender and destination, dispatch date, service, latest scan, contents description and value evidence. |
Ecommerce and Business Tracking
A merchant should store both the GSC booking reference and the underlying partner waybill. That separation helps customer-service teams distinguish booking creation, physical acceptance, customs events and final-mile delivery.

FAQ
Basic FAQs
Enter the shipment or waybill number in 17TRACK, then verify the underlying partner shown in the result.
Look on the freight receipt, shipping label or seller’s dispatch message and distinguish it from the order number.
GSC does not publish one universal format; the number may follow the format of the selected express or postal partner.
The first event normally appears after the issuing operator receives and scans the shipment, not merely when a booking is created.
A handoff, line-haul or customs stage may have limited scanning; ask the shipper to identify the responsible partner.
Transit time depends on route, mode, customs and final-mile partner, and the supplied official pages do not publish one universal delivery period.
Read the exception event, check the destination carrier and ask the seller or shipper about redelivery or collection.
Check entrances, reception, household members and neighbors, then request delivery evidence and contact the local delivery operator.
The shipper should preserve packaging and evidence and ask GSC which partner claim channel applies to the booked service.
Call 020-86263835 or use the contact page on the official GSC website.
Expert FAQs
No. GSC describes agency relationships with those operators, so the partner may perform scans and issue the waybill while GSC coordinates the forwarding service.
No. A GSC-arranged shipment can carry a partner-issued express or postal identifier.
No. Customs arrival indicates presentation or processing; a separate release or clearance event is needed before import delivery can proceed.
Consolidation, airline or ocean transport, customs and partner handoff stages may generate fewer public events than parcel sorting.
The supplied GSC pages do not publish a public tracking API; businesses can evaluate 17TRACK’s documented multi-carrier API after confirming the applicable carrier code.
