About YL

YL(YLExp or YiLong Express or 颐龙快递) is the English display name used for this tracking page. The supplied official website identifies the Chinese business as 颐龙快递 and presents YL as an international express and postal-service agency operating from China. The site lists international postal products, major express services, sea and air transport, and regional dedicated lines.

Verified field	Information
Official name shown on the site	颐龙快递
Official website	http://www.ylexp.com/
Carrier type	China-based international express and postal-service agency.
Primary region	International shipments originating through China, with listed services covering Asia, Europe, North America and other global destinations.
Official tracking entry	The YL homepage contains a “快递跟踪” tracking function accepting up to 30 query numbers, one per line.
Parent organization	The supplied pages identify YL as an independent brand and agency; a parent organization is not stated.

Carrier Entity Relationships

Entity	Relationship summary
Canonical carrier	YL is the display entity for the international logistics business presented on the supplied official website.
Operated or arranged services	YL lists EMS, E邮宝, E特快, 中速TNT, major express services, postal small packets, air and sea services, and regional dedicated lines.
Postal products	YL states that it acts as a first-level postal agent for several listed postal products; the underlying postal operator issues or processes the relevant postal shipment.
International partners	The service pages identify postal and express partners including EMS, TNT, DHL, UPS and FedEx, depending on the selected service. A partner scan does not by itself prove that YL physically accepted the parcel.
Tracking relationship	YL provides a tracking entry on its website, while 17TRACK independently aggregates available events from supported carriers and postal operators.

Quick Answer

Enter the shipment identifier supplied by the seller or shown on the YL receipt into the tracking tool on the official YL website or into 17TRACK. If no event appears, first check whether the number is a tracking number rather than an order number, whether every character was copied correctly, and whether the postal or express partner has created the first physical scan.

Pro Tip: 17TRACK is an independent tracking platform. It does not transport parcels, change addresses, approve refunds, open claims or control customs decisions.

How to Track YL Packages

Use the official YL tracking entry for a shipment arranged through YL, or use 17TRACK when the underlying postal or express carrier is supported. The seller is normally the best first contact for a missing identifier or a service-selection question.

Path	Steps
Official YL tracking	Open the official website, choose 快递跟踪, enter the number, and submit the query. The homepage states that up to 30 numbers can be entered, one per line.
17TRACK	Open 17TRACK, paste the number, allow carrier recognition or select the supported carrier, and review the latest event and handoff information.
Where to find the number	Check the seller’s dispatch notice, shipping label, postal receipt, YL order record or partner-carrier receipt. An order number and a reference number are not automatically tracking numbers.
No result	Remove spaces or punctuation only when the tracking page requires it, compare each character, wait for the first carrier scan, and ask the seller which underlying service issued the number.

Tracking Number Formats and Examples

YL arranges multiple postal and express products, so there is no single universal YL number pattern. The issuer may be YL, a postal operator, an express partner or a destination last-mile operator. Prefixes alone should not be treated as conclusive proof of service.

Tracking Number Format

Identifier family

Normalized pattern

International postal S10-style identifier

Two letters + nine digits + two-letter origin code, such as AA#########CN or AA#########US.

View all details for international postal identifiers

Issued by	The origin postal operator or postal network normally issues the identifier.
Typical use	Registered, tracked small-packet or parcel services may use this structure.
Who sees it	A marketplace buyer may see it in a dispatch email or order page; a destination postal operator may continue using the same number after handoff.
Caveat	The service indicator and origin code require carrier-system interpretation; the pattern alone does not prove that YL issued the number.

Express-partner number

An alphanumeric or numeric identifier supplied by the selected express network; use the exact number printed on the partner label.

View all details for express-partner numbers

Partners listed by YL	The official service pages list EMS, TNT, DHL, UPS and FedEx in relevant service descriptions.
Where it appears	The number can appear on a commercial label, receipt, seller dispatch notice or partner tracking page.
Tracking scope	Events may be richer on the underlying partner’s website than on an intermediary page.
Caveat	Ask the seller which partner is carrying the shipment when automatic recognition selects the wrong carrier.

Merchant order or reference ID

A seller-generated order, reference or transaction identifier; no universal format is confirmed for YL.

View all details for merchant references

Function	A merchant reference identifies a sale or internal shipment record rather than a carrier scan record.
Action	Request the carrier tracking number from the seller if the reference cannot be found on the tracking page.
API submission	Submit the carrier tracking identifier, not an unverified marketplace order number.

Tracking Statuses and Meanings

A tracking event describes the latest recorded scan, not necessarily the exact physical location at the moment of viewing. “Label created” or a partner pre-advice event does not prove that the parcel has been physically accepted.

Common Tracking Problems and Solutions

The correct escalation path depends on the latest physical scan and the product selected. For a marketplace order, the seller or shipper can often obtain information that a recipient cannot request directly.

Problem & Solution

Problem or status

Check first

Invalid number

Compare the number with the label or seller notice and confirm the underlying postal or express service.

View all details for an invalid YL number

Likely cause	An order ID, reference ID or incomplete label may have been entered instead of a tracking number.
Immediate action	Ask the seller for the exact carrier identifier and selected service.
Escalation	Escalate to the seller or shipper if the label information conflicts with the dispatch notice.

No update after dispatch

Check whether the first postal or partner acceptance scan has occurred.

Long international gap

Check export, airline, customs and destination-postal pages; postal small packets can have limited event visibility.

Delivered but not received

Check the delivery location, household members, reception desk, neighbors and any proof-of-delivery information.

Customs hold

Contact the seller or responsible destination operator about documents, duties or import instructions.

Return to sender

Ask the seller or shipper why delivery failed and whether a new shipment or return arrangement is available.

International Shipping, Customs and Carrier Handoffs

For cross-border shipments, YL may arrange a postal or express product whose physical custody changes during export, line-haul, customs and last-mile delivery. A destination-country scan does not by itself prove customs release or final delivery.

International Flow

Stage

Typical event

Origin preparation

Label or electronic shipment data is prepared; physical acceptance may still be pending.

View all details for origin preparation

Responsible entity	The sender and YL or the selected origin partner prepare the shipment.
Visibility gap	Tracking may remain unchanged until the first acceptance or processing scan.
Customer action	Confirm the address, item description and declared value with the sender.

Export and line-haul

Origin processing, export security, departure and international transit events.

Destination handoff

A postal or express partner may receive electronic pre-advice before the physical parcel is scanned.

Import customs

The parcel may await examination, documents, duties or release.

Destination last mile

The destination operator sorts, attempts delivery, delivers, holds or returns the shipment.

The supplied YL pages do not publish a universal customs timeline, tax policy or destination-partner list. Do not treat “arrived in destination country” as “released by customs,” and do not assume that the number was issued by YL merely because YL arranged the shipment.

Lost, Damaged, Claims and Refunds

Tracking inquiries, missing-mail searches, insurance claims, postage refunds and marketplace refunds are separate processes. The available remedy depends on the product and the contracting shipper.

Process

Use when

YL or shipper inquiry

Use when tracking is contradictory, stalled or missing; the shipper should provide the label, dispatch date and latest scan.

View evidence and outcome for an inquiry

Who files	The sender or account holder should initiate the inquiry with YL or the underlying operator.
Evidence	Tracking number, receipt, shipment date, addresses, contents description, declared value and recent events.
Outcome	An explanation, trace request, additional information request or carrier response may follow.

E邮宝 loss or damage

The supplied E邮宝 page states that loss, delay and damage compensation is not provided.

Sweden Post small packet

The supplied page describes compensation limits and a 90-day no-response condition after a query is opened; the terms apply to that product and should be confirmed with YL before filing.

Marketplace refund

Request a seller or marketplace remedy separately; 17TRACK cannot approve or issue it.

Shipping Restrictions and Special Handling

The YL product pages prohibit or restrict several categories. Rules vary by route and partner, so the current YL acceptance decision should control before tendering a shipment.

Category	Published treatment
Liquids, powders and pastes	Listed as prohibited for several YL-arranged postal services; rejection or confiscation may affect tracking.
Batteries and dangerous goods	Restrictions vary by product; E邮宝 and EMS pages list batteries among prohibited items, while the Sweden Post page separately describes acceptance conditions for some battery goods.
Weapons, drugs and prohibited exports	Listed as prohibited; the sender should check applicable postal, customs and aviation rules before dispatch.
Brand or intellectual-property goods	Brand products require YL confirmation for E邮宝, and the EMS page prohibits infringement-related goods.
Perishable goods and live plants	The China Post small-packet page lists live plants, animals and perishable products as prohibited.

Customer Service

Use the official YL website’s contact and tracking navigation for current assistance. The supplied evidence does not include a verified telephone number, email address, live-chat schedule or regional opening hours, so those details are not reproduced here.

Ecommerce and Business Tracking

YL’s homepage supports multi-number tracking and lists online ordering and member functions. For merchants, the practical distinction is between a YL account workflow, an underlying carrier’s system and a multi-carrier aggregation API.

FAQ

Basic FAQs

1. How do I track my YL package?

Enter the tracking number on the official YL website or use 17TRACK to view available shipment events.

2. Where can I find my YL tracking number?

Look in the seller’s dispatch message, shipping label, postal receipt or YL order record; an order number may not be trackable.

3. What does a YL tracking number look like?

YL handles multiple services, so formats vary from postal identifiers to express-partner numbers; use the complete identifier and do not infer service from a prefix alone.

4. When will the first YL tracking event appear?

The first event normally appears after the responsible postal or express operator records acceptance or processing; label creation alone does not prove physical handover.

5. Why is my YL tracking not updating?

International sorting, airline movement, customs and destination handoff can create gaps; verify the number and ask the seller which operator currently holds the parcel.

6. How long does YL delivery take?

The published E特快 ranges are 2–4, 5–7 or 7–10 business days by destination group, while China Post small packets are described with broader ranges; these are estimates, not guarantees.

7. What should I do after a failed delivery?

Read the latest exception, check the address and contact the seller or destination operator promptly about redelivery, collection or return options.

8. What should I do if YL shows delivered but I have not received the parcel?

Check the delivery location, household members, reception desk and neighbors, then request proof of delivery and ask the seller to open a carrier inquiry.

9. Can I claim for a lost or damaged YL parcel?

The answer depends on the selected product; the supplied E邮宝 page states that loss, delay and damage compensation is not provided, so confirm the product terms with the shipper.

10. How do I contact YL?

Use the contact and tracking navigation on the official YL website and prepare the tracking number, shipment date, service type, addresses and latest scan.

Expert FAQs

11. Is YL the same as the postal operator shown in tracking?

No; YL may arrange or act as an agent for a postal product while the underlying postal operator issues scans and controls physical processing.

12. What does YL’s E特快 tracking relationship with EMS mean?

The E特快 page states that the service uses the EMS transport method and can be tracked on the EMS website, so an EMS event does not mean EMS was replaced by YL as the operating postal network.

13. Why can a partner number be trackable even if YL did not issue it?

YL can arrange a shipment using a postal or express partner, and that partner may issue the operational label and tracking identifier.

14. What happens during an international YL handoff?

Electronic pre-advice may appear before physical acceptance, followed by export processing, international transport, customs and destination delivery; the same identifier may continue across a postal handoff.

15. Does arrival in the destination country mean customs has released the shipment?

No; arrival, exchange-office processing and customs release are separate events, and the recipient may still need to provide documents or pay assessed charges.

16. Can businesses track YL shipments in bulk?

The official homepage states that up to 30 numbers can be queried one per line; a current public YL developer API is not established by the supplied official evidence.

17. Can 17TRACK change a YL delivery address or approve a claim?

No; 17TRACK displays available tracking data but cannot change delivery instructions, make customs decisions, approve claims or issue refunds.
