1ST, operated by 1ST Group in China, is an international express and cross-border logistics provider serving manufacturers, e-commerce sellers and businesses shipping goods overseas. The group was established in Shenzhen and has built logistics channels connecting China with major international markets, including the United States, Europe and the Middle East. Its network also includes a presence in Hong Kong and the United Arab Emirates, supporting cross-border movements through key trade and distribution hubs.
The company's services cover international express delivery, cross-border e-commerce small parcels, dedicated B2B and B2C lines, air and sea freight, customs declaration and warehousing. 1ST also works with major international express networks such as UPS, FedEx and DHL and operates dedicated routes for destinations including the United States, Europe and the Middle East. These options allow customers to choose between parcel-focused services and larger freight solutions according to shipment size, destination and required transit time.
For e-commerce logistics, 1ST provides dedicated parcel channels and logistics support for sellers shipping from China to overseas buyers. The group also has overseas warehousing capabilities, including facilities in the United States, which can support storage, customs handling and onward distribution. This makes the network relevant not only for one-off international parcels but also for merchants that need recurring fulfillment and delivery services in destination markets.
Shipment visibility is an important part of the service. 1ST states that shipments can be followed through its cargo tracking system, and its logistics channels support end-to-end tracking updates. Readers using 4Tracking can Track 1ST packages from the same universal package tracking page used for other carriers, making it easier to follow cross-border orders even when different logistics companies are involved during the journey.
How 1ST shipment tracking works
Each eligible 1ST shipment is assigned a tracking number that identifies the package in the carrier's logistics system. As the parcel moves through acceptance, processing, export transportation, customs procedures and destination delivery, Tracking events can be added to the shipment history. Some routes may also involve a local or last-mile carrier, so a second tracking number can appear later in the journey when the shipment is transferred for final delivery.
To Track a 1ST shipment with 4Tracking, enter the complete tracking number in the tracking field and start the search. 4Tracking can automatically detect many supported carriers, which means you normally do not need to choose a carrier first. If the shipment is not identified automatically, select 1ST manually and run the package tracking search again.
You can also check the shipment through 1ST's own cargo tracking service. The company's official guidance says customers can use its tracking website to enter the shipment number and view the transport status, or contact their 1ST business or customer-service representative for an update. If a newly created shipment does not show results immediately, allow time for the first operational scan to be uploaded and confirm the number with the sender before assuming the package is missing.
1ST tracking number formats
Common 1ST Express tracking numbers can appear in more than one format. A frequently seen format begins with 1S followed by about 8 to 10 digits. Another commonly used form is an all-numeric identifier containing about 12 to 14 digits. Illustrative pattern examples are 1S12345678 and 123456789012; these examples only demonstrate the format and are not real shipment numbers.
Because 1ST operates several logistics products and may use partner or last-mile networks, not every shipment is guaranteed to follow the same pattern. The group's official FAQ also refers to other channel-specific numbers, including AG-series numbers for certain postal-related services and later USPS numbers on some United States routes. For package tracking, always use the complete number supplied by the seller or shipper and avoid removing letters, leading zeros or other characters.
1ST delivery times
Delivery time depends on the selected route, service level, customs processing, available transport capacity and the destination country's final-mile network. Typical international express planning ranges for 1ST shipments are about 3–7 business days from China to the United States, about 5–12 business days from China to Europe and about 5–15 business days from China to the Middle East. These ranges should be treated as estimates rather than guaranteed delivery dates.
Different 1ST products can take longer. The company's official FAQ notes that an economy service may have an overall transit time of roughly 12–18 days, and some United States services can take several days before a USPS final-mile tracking number is returned. This is why two packages traveling to the same country may not arrive on the same schedule if they use different transport channels or customs arrangements.
For example, an express parcel moving from China to the United States may arrive within the typical 3–7 business-day range, while a European shipment may need around 5–12 business days and a Middle East shipment around 5–15 business days. Customs inspections, incomplete recipient information, restricted-goods checks, peak-season congestion and handoff to a destination carrier can extend these estimates. The latest Tracking event is therefore more useful than counting calendar days alone.

How to contact 1ST about shipment issues
If your 1ST package has not updated, appears delayed, is held during customs processing or has another delivery problem, first keep the full tracking number ready and review the latest package tracking event. 1ST's official guidance says customers can ask their business or customer-service contact to check a shipment's transport status in addition to using the online tracking system.
1ST Group publishes the telephone number 0755-29778100 and the general contact email akoli@1st56.com. Its headquarters contact address is Building 36, Zone 5, Huaide Cuigang Industrial Park, Fuyong Street, Bao'an District, Shenzhen, China. When contacting the company, provide the tracking number, sender and recipient details, shipment date and a short description of the problem so the shipment can be identified more quickly.
For customs delays, 1ST advises that the sender should help obtain the recipient's cooperation and provide handling instructions when necessary. If the shipment was purchased from an online seller or marketplace, contacting the seller is also useful because the shipper may have the commercial documents, service-channel details or account information required for an investigation.
