About Byt

Byt is the customer-facing carrier name used for 上海佰邮通物流有限公司, also described on its company page as 佰邮通国际物流. The company provides cross-border logistics solutions for e-commerce, including international express forwarding, international small packets, overseas warehousing, delivery and value-added services. Byt operates as a logistics solution provider and forwarding coordinator rather than as a national postal operator.

Field	Verified information
Official name	上海佰邮通物流有限公司.
Official website	https://www.byt56.com.cn/
Carrier type	Cross-border e-commerce logistics provider and forwarding coordinator.
Primary region	China-origin international logistics with global destination coverage shown in the official destination selector.

Carrier Entity Relationships

Entity	Entity type
上海佰邮通物流有限公司	This is the company identified in the official footer as the legal operating entity behind Byt.
International EMS and international express	These are logistics products described by Byt; the official page says international express may transit through mainland China, Hong Kong, Macao and Malaysia.
International small packet	Byt describes this product as directly interfacing with overseas postal operators, so the destination postal operator may provide later-mile events.
Overseas warehouses	Byt describes overseas warehousing as including storage, delivery, value-added and e-commerce services.
17TRACK	17TRACK is an independent platform that may aggregate available events for a Byt shipment; 17TRACK does not operate the shipment.

Quick Answer

Enter the shipment identifier supplied by the seller, shipping label or Byt account into the official Byt tracking entry or into 17TRACK. If no result appears, check whether the number is an order number rather than a tracking number, remove spaces or punctuation, confirm the characters, and allow time for the first carrier scan. 17TRACK is independent of Byt and cannot change an address, approve a refund or decide a claim.

How to Track Byt Packages

The official Byt website provides the primary tracking entry. 17TRACK provides a separate multi-carrier view when events from Byt or a connected postal or delivery operator are available.

Path	Steps
Official Byt tracking	Open the Byt website, choose the “轨迹查询” entry, enter the shipment number supplied by the sender, and review the latest event and route information.
17TRACK	Open 17TRACK, paste the shipment number, allow automatic carrier recognition, and compare the event timeline with the seller’s shipping notice.
No number or no result	Ask the seller for the carrier-issued or partner-issued shipment identifier. An order number, merchant reference, quote number or warehouse number may not be trackable.

Tracking Number Formats and Examples

The supplied Byt pages do not publish one universal Byt number pattern. Byt’s products include international express, international small packets, China EMS, Hong Kong EMS, China Post small packets and postal or dedicated-line products. The identifier may therefore be issued by Byt, an origin postal operator or a downstream partner.

Tracking Number Format

Identifier family	Normalized pattern
Byt shipment identifier	Carrier-specific alphanumeric or numeric identifier; use the exact value supplied on the label or shipping notice.
International postal S10	Two letters, eight serial digits, one check digit and a two-letter origin country code, shown in a redacted form such as AA#########CN.
EMS or postal partner number	The origin postal operator may issue the identifier. A Byt result does not by itself prove that Byt issued the number.
Merchant order or reference	Seller-generated reference used for order management; it may not produce transport scans.
Last-mile identifier	A destination delivery operator may assign a separate local number after handoff. The original number can continue to show events where systems are linked.

Pro Tip: Do not infer the service solely from a prefix. Preserve the complete identifier, including letters and country suffixes, and let the official Byt tracker or 17TRACK identify the available carrier.

Tracking Statuses and Meanings

Tracking events describe the latest reported scan, not necessarily the physical position at the exact moment of viewing. Responsibility can move between Byt, a postal operator, customs and a destination delivery partner.

Status Quick Lookup

Status	Lifecycle stage
Label created or pre-advice	Pre-shipment: shipment data exists, while physical acceptance may still be pending.
Accepted or received	Acceptance: a participating operator has recorded possession or intake.
In transit	Sorting or line-haul: the shipment is moving through the declared route.
Customs or handover	Cross-border processing: customs or another carrier may be responsible for the next event.
Out for delivery	Last mile: the destination delivery operator has assigned the shipment to a delivery round.
Delivered	A delivery scan has been recorded; check the delivery location and proof details if the parcel is missing.
Exception or return	An address, access, customs, damage or routing issue requires the sender, recipient or delivery operator to act.

Services and Delivery Times

Byt’s official pages identify product categories and a destination-based price calculator, but the supplied pages do not publish a single delivery promise for every route. Delivery depends on product, origin, destination, handoff and customs processing.

Service Comparison

Service	Service type
International EMS	Express postal product described by Byt as an important South China partner.
International express	Cross-border forwarding through mainland China, Hong Kong, Macao or Malaysia to global destinations.
International small packet	Postal-connected cross-border product with tracking support described by Byt.
Overseas warehousing	Storage, delivery, value-added and e-commerce logistics services.

Delivery Time

Service	Published delivery standard
International EMS	Route quotation and service selection should be checked with Byt for the origin and destination.
International small packet	Route-dependent postal transit; customs and destination delivery scans can affect the visible timeline.
Overseas warehousing	Domestic destination delivery timing depends on the warehouse route and selected delivery service.

Destination Country Delivery Times

Destination country or region	Route planning note
United States, Canada and Mexico	Byt’s official destination selector includes these markets; confirm the selected postal, express or dedicated-line route before dispatch.
United Kingdom, Germany, France, Spain and Italy	Byt’s selector includes these European markets; import processing and local delivery scans form part of the end-to-end timeline.
Japan, South Korea, Australia and New Zealand	These markets appear in Byt’s destination list; route and service should be verified through the quote process.
Singapore, Malaysia, Thailand, India, Philippines and Indonesia	These markets appear in Byt’s destination list; customs documentation and destination postal handoff may affect visibility.
Brazil, Chile, United Arab Emirates, Saudi Arabia and South Africa	These markets appear in Byt’s destination list; customs requirements and local delivery arrangements should be checked before shipment.

Common Tracking Problems and Solutions

Problem or status	Check first and immediate action
Invalid number	Compare the number with the seller’s notice, remove spaces, and distinguish it from an order or reference number.
No tracking events	The label may have been created before physical acceptance. Ask the sender to confirm handover and the correct product.
Long gap or stuck in transit	Cross-border transport, customs, weekends, peak periods and missed scans can create gaps. Ask the sender to open a carrier inquiry when the route warrants escalation.
Shipping partner handoff	Electronic pre-advice does not necessarily mean the next operator has received the parcel. Check for a physical acceptance scan.
Address, delivery failure or return	Contact the seller and the destination delivery operator promptly; the sender may need to correct commercial shipping data or request an inquiry.
Customs hold	Review the destination authority’s request, taxes and import documents. Do not treat arrival at an exchange facility as customs release.
Delivered but not received	Check the mailbox, safe place, household members, reception desk and neighbors; then request proof of delivery and contact the local delivery operator and seller.
Lost or damaged parcel	Preserve packaging, photographs, invoice and shipment records. The sender should begin the transport inquiry or claim with the party that purchased the service.

International Shipping, Customs and Carrier Handoffs

For an international Byt shipment, the physical custodian can change during export, line-haul, customs and final delivery. Byt’s official description specifically refers to overseas postal connections and transit through several Asian logistics gateways.

Stage	Responsible entity and customer action
Shipment creation	Byt or a forwarding channel records shipment data; the sender should verify the address, contents and declaration.
Origin acceptance and export processing	Byt, an origin warehouse or a postal/express operator handles intake and export preparation.
Export customs and security	Authorities and transport operators review the shipment; accurate item descriptions and values reduce avoidable queries.
Line-haul and gateway transit	The shipment moves through the selected route, which may include mainland China, Hong Kong, Macao or Malaysia.
Destination customs	The destination authority controls import release; arrival does not equal release and taxes may be payable by the importer.
Partner handoff and last mile	An overseas postal or delivery partner may receive the parcel and issue the next scan. The original number may remain linked, or a local identifier may appear.

Delivery Management and Post-shipment Options

The supplied Byt pages describe logistics handling, warehousing and customer contact, but do not describe a public self-service interception, redirection or delivery-preference tool. For a change after dispatch, the buyer should contact the seller first because the sender or contracting account generally controls the transport request.

Claims and Shipping Restrictions

Claims and Refunds

Process	Use when
Tracking inquiry	Use when an event is missing or the shipment needs route clarification; provide the complete identifier and latest scan.
Loss or damage request	Byt’s homepage states that lost and damaged shipments receive 100% compensation under its displayed service commitment; retain packaging, contents evidence, value records and shipment documents and confirm the applicable terms with Byt.
Seller refund	A marketplace seller decides the buyer refund under the sales contract; 17TRACK cannot approve it.

Shipping Restrictions

Category	Official handling principle
Dangerous and prohibited goods	The China EMS information on Byt’s service page excludes explosives, flammable, corrosive, radioactive, toxic, perishable and other legally prohibited items.
Cash, narcotics and unlawful publications	The same page identifies cash, narcotics, psychotropic substances and prohibited publications or materials as excluded categories.
Packaging and declarations	Use postal-compliant packaging and provide accurate English or French descriptions, quantities, declared value and origin for goods intended for international clearance.
Address and barcodes	Provide a detailed address and telephone number where possible. Byt’s China EMS instructions warn that unrelated extra barcodes can cause handling and online-scan delays.

Ecommerce and Business Tracking

For e-commerce operations, separate the seller’s order reference from the transport identifier. Merchants can use the Byt account and contact channels for shipment follow-up, while 17TRACK can provide a multi-carrier tracking workflow when the relevant carrier data is supported.

FAQ

Basic FAQs

1. How do I track my Byt package?

Enter the shipment identifier on the official Byt tracking entry or on 17TRACK, then review the latest reported event.

2. Where can I find my Byt tracking number?

Look on the seller’s dispatch email, shipping label, warehouse notice or Byt shipment record.

3. What does a Byt tracking number look like?

Byt uses multiple logistics products, so there is no single pattern shown across the supplied official pages; a postal partner may issue an S10-style identifier.

4. Why has my Byt tracking number produced no event?

The label may exist before physical acceptance. Check the characters and ask the sender to confirm handover.

5. How long does a Byt shipment take?

Timing depends on product, route, destination, customs and last-mile handling; use Byt’s quotation process for the selected origin and destination.

6. What should I do if my Byt package is not updating?

Check the last scan, allow for transport or handoff gaps, and ask the sender to contact Byt when the shipment requires an inquiry.

7. What should I do after a Byt delivery failure?

Check the address and delivery notice, then contact the seller and the destination delivery operator promptly.

8. Why does my Byt shipment say delivered but I cannot find it?

Check the safe place, mailbox, household members, reception desk and neighbors, then request proof of delivery and seller assistance.

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

Preserve packaging and evidence and ask the sender or contracting account to start the appropriate Byt transport inquiry or claim.

10. How can I contact Byt?

Use the official website or call 021-67766171 with the shipment identifier and latest tracking event ready.

Expert FAQs

11. Is Byt the same as the destination postal operator?

No. Byt describes itself as a cross-border logistics provider, while an overseas postal or delivery partner may handle destination processing and final delivery.

12. Does a Byt tracking result prove that Byt issued the number?

No. A result can be associated with an origin postal operator, Byt channel or destination partner; issuance and tracking visibility are separate relationships.

13. Does arrival in the destination country mean customs has released my Byt package?

No. Arrival, exchange-office processing and customs release are separate events, and the destination authority may request documents or payment.

14. Why can a Byt international shipment have a tracking gap?

The parcel may be between export processing, line-haul, customs, postal exchange and last-mile scans; the original identifier may continue after handoff.

15. What information should a business give Byt about a shipment problem?

Provide the complete identifier, service, dispatch date, origin and destination, address, latest scan, contents and value, plus packaging or damage photographs when applicable.
