One Line provides cross-border logistics, warehousing and customs-clearance solutions for ecommerce customers.

View all relationship details for One Line

Operated services	One Line lists dedicated small-parcel lines, postal small parcels, air lines and sea lines among its logistics products.
Tracking product	The official website provides a tracking-number entry described as a tracking service.
Network facilities	One Line identifies distribution centers in Wuxi, Hangzhou, Humen, Zhongshan, Shanghai and Quanzhou.
API relationship	One Line publishes an API-support page covering login, shipment import, label files, tracking queries, deletion and receiving-channel queries.
17TRACK relationship	17TRACK is an independent tracking platform that may aggregate available events; it does not operate One Line transportation or resolve One Line claims.

Quick Answer

Enter the shipment identifier supplied by the seller or One Line in the official tracking area, or submit it to 17TRACK for available events. If no result appears, first check whether you entered a customer shipment number rather than an order number, remove spaces or hyphens, and allow time for the first operational scan. 17TRACK is independent and cannot change an address, issue a refund or approve a claim.

How to Track One Line Packages

Copy the shipment or customer number from the seller’s dispatch message, label or One Line transaction record.
Open the official One Line tracking page and submit the identifier.
If the official result is unavailable, try 17TRACK with the same identifier and review the latest location and event time.
For an ecommerce order, contact the seller when the identifier is only an order or reference number; the seller can provide the shipment number or investigate the dispatch record.

Pro Tip: One Line’s API documentation uses customer shipment numbers for tracking queries. A marketplace order number may therefore need to be mapped to the logistics identifier by the seller.

Tracking Number Formats and Examples

The published API examples show customer shipment identifiers in numeric and alphanumeric forms. The official evidence does not establish one universal public prefix or length rule, so the identifier should be validated through the official tracking page or automatic carrier recognition.

Tracking Number Format

Identifier family

Example pattern

Customer shipment number

10–14 digit-style placeholder: ########## or ##############

View all format details for customer shipment numbers

Issued by	The ecommerce customer or logistics workflow may create the customer shipment identifier; the published examples do not establish a universal issuing rule.
Typical use	Used in the documented batch-import and tracking-query API examples.
Where seen	May appear in a seller system, dispatch record, label workflow or tracking result.
Tracking scope	One Line’s API tracking endpoint accepts a list of customer shipment numbers and returns track events where records exist.
Caveat	Do not infer a service, destination or partner solely from digits; submit the complete identifier without accidental punctuation.

Partner or transfer number

Alphanumeric placeholder: ABCD123

View all format details for partner or transfer numbers

Issued by	The API example labels this as an additional number and does not identify a fixed carrier or postal standard.
Typical use	May link a seller record with another logistics identifier during fulfillment.
Who sees it	Usually the merchant or logistics operator; a buyer may see it in a dispatch notification.
Validation	Use the number associated with the One Line tracking record rather than an unrelated marketplace reference.

FAQ

Basic FAQs

1. How do I track my One Line package?

Enter the shipment number on the official One Line tracking page or use 17TRACK to view available events.

2. Where can I find my One Line tracking number?

Check the seller’s dispatch message, logistics label or shipment record, and ask the seller if only an order number is shown.

3. What does a One Line tracking number look like?

Published API examples include numeric-style customer shipment numbers and an alphanumeric additional number; One Line does not publish one universal public format in the supplied material.

4. When will the first One Line tracking event appear?

The first event appears when a shipment record or operational scan is available, so label creation may precede physical acceptance.

5. Why is my One Line tracking not updating?

A handoff, transport interval or missing scan can delay visibility; ask the seller to verify the shipment record when the promised delivery window passes.

6. How long does One Line delivery take?

Delivery depends on the selected parcel, postal, air or sea route, origin, destination, customs and final-mile processing.

7. What should I do after a One Line delivery attempt fails?

Check the latest event and contact the seller or delivery operator shown there for redelivery or pickup instructions.

8. What should I do if One Line says delivered but I have not received the parcel?

Check the delivery address, household members, reception desk and safe place, then ask the seller to request proof of delivery or an investigation.

9. How do I report a lost or damaged One Line shipment?

Preserve packaging and evidence, then contact the seller or eligible shipping-account holder so the appropriate carrier inquiry or claim can be started.

10. How can I contact One Line?

Use the official tracking or support entry and the published telephone number 13823642553; prepare the shipment number and latest event.

Expert FAQs

11. Does One Line tracking prove physical acceptance?

No; a draft or pre-advice record can exist before a physical station scan, so acceptance should be established by an operational event.

12. Which identifier should a business send to One Line’s tracking API?

The published tracking example uses customer shipment numbers in a list, while unrelated marketplace order references require merchant-side mapping.

13. Can One Line import shipments in batches?

Yes, the published batch-import example states that one import request supports up to 100 waybills.

14. Does One Line provide air and sea logistics products?

Yes, the official navigation lists air dedicated lines and sea dedicated-line products alongside parcel services.

15. Can a destination carrier receive a One Line shipment?

Yes, cross-border shipments can involve destination operators, but the supplied pages do not establish one universal partner for every route.

16. Does arrival in the destination country mean customs is complete?

No; destination arrival and customs release are separate events, and import processing may still require documents or payment.

17. Can 17TRACK change a One Line delivery address?

No; 17TRACK displays available tracking data and cannot authorize address changes, redelivery, refunds or claims.
