About Relay

Relay is a UK-focused ecommerce parcel delivery carrier and delivery-technology operator. Relay works in the carrier chain as a first-mile, sortation, line-haul and last-mile delivery network for merchants and recipients where a retailer has selected Relay for delivery or returns. Relay should not be confused with unrelated companies named Relay in payments, communications, staffing or software.

Carrier Entity Relationships

Entity

Relationship

Relay

Relay is the canonical carrier brand used for the UK ecommerce delivery network.

View all details for Relay

Entity type	Canonical carrier brand.
Why it matters to tracking	Use Relay only when the retailer, shipping notification or tracking event names Relay as the delivery carrier.
Official evidence	Relay official website identifies the Relay delivery brand and ecommerce delivery network.

Relay delivery services

Relay delivery services are operated for ecommerce merchants and may include outbound parcels and returns where the merchant offers them.

View all details for Relay delivery services

Entity type	Operated service entities.
Why it matters to tracking	Service availability, delivery promises and support options are normally controlled by the merchant contract and the recipient-facing tracking page.
Official evidence	Relay official website describes ecommerce delivery as its operating focus.

Retailer or marketplace

The retailer usually creates the order, issues the customer notification and controls refunds or replacement decisions.

View all details for retailer or marketplace

Entity type	Merchant and shipper.
Why it matters to tracking	A retailer order number is not always the same as a Relay tracking number, and the retailer is usually the party that can refund, reship or change commercial order details.
Official evidence	Relay positions its service for ecommerce businesses, so customer support often starts from the merchant notification.

17TRACK

17TRACK aggregates available tracking events from Relay and other carriers but does not transport parcels.

View all details for 17TRACK

Entity type	Independent multi-carrier tracking platform.
Why it matters to tracking	17TRACK can help identify the carrier and normalize statuses, but Relay or the merchant remains responsible for delivery operations and after-sales actions.
Official evidence	17TRACK API documentation describes multi-carrier registration and tracking workflows.

Quick Answer

To track a Relay package, enter the tracking number from your retailer dispatch email, SMS, app order page or Relay tracking link on the official Relay tracking experience or on 17TRACK. If the result is empty, first check whether you entered a shipment tracking number rather than an order number, whether the merchant has only created a label, and whether the first physical scan has happened.

Pro Tip: 17TRACK is an independent tracking platform. 17TRACK can show available Relay tracking events and carrier recognition results, but 17TRACK cannot change the delivery address, approve a refund, open a carrier claim or instruct a courier.

How to Track Relay Packages

Relay tracking starts with the identifier issued in the retailer shipment notification. The most reliable first source is the retailer’s “track my order” link because it may contain the exact Relay tracking reference and delivery-management options attached to that order.

Path	Steps
Official or retailer tracking	Open the retailer dispatch email, SMS or order page; select the Relay tracking link; verify the postcode or delivery details if requested; review the latest event and any delivery options.
17TRACK tracking	Copy the Relay tracking number; paste it into 17TRACK; let carrier auto-detection run or select Relay if available; compare the scan time, location and status with the retailer page.
No tracking number	Check spam folders, the retailer order page and shipment confirmation. If only an order number is available, ask the retailer for the carrier tracking number.
Number not active	Wait for the first physical acceptance or depot scan. A label-created record can exist before Relay has the parcel.

Tracking Number Formats and Examples

Relay has not publicly confirmed a complete universal tracking-number specification on the reviewed official pages. Treat any examples below as normalized, masked identifier families for recognition, not as proof that a parcel is carried by Relay. A number searchable on a Relay or retailer page may be issued by the merchant platform, Relay, or a partner system.

Tracking Number Format

Identifier family

Normalized pattern

Relay shipment tracking number

Masked alphanumeric or numeric reference such as RLY #### #### or #### #### ####; exact public rule not confirmed.

Who sees it and where	Recipients usually see it in the retailer dispatch email, SMS, order page or Relay tracking link.
Tracking scope	Pre-advice, acceptance, depot processing, out-for-delivery, delivery, exception and return events when shared.
Important caveat	Do not infer Relay service type from prefix alone because Relay has not published a full prefix-to-service map.

Retailer order number

Issued by	Retailer, marketplace or ecommerce platform.
Typical service/use	Customer-service lookup, invoice matching and order management.
Who sees it and where	Buyers see it on checkout confirmation, invoices and account order history.
Tracking scope	May not track directly unless the retailer page maps it to a Relay tracking number.
Important caveat	If 17TRACK returns no result, ask the retailer for the carrier tracking number rather than the order number.

Partner or upstream carrier reference

Partner-issued numeric or alphanumeric reference; pattern depends on the upstream network.

View all details for partner or upstream carrier reference

Length/structure	Not controlled by Relay where the parcel originates outside the Relay network.
Issued by	Origin carrier, fulfillment provider, consolidator or merchant logistics platform.

Tracking scope	Visibility may stop at handoff unless identifiers are linked by the merchant or tracking platform.
Important caveat	Relay being shown as last-mile carrier does not prove Relay issued the original number.

International Shipping, Customs and Carrier Handoffs

Relay is primarily described as a UK ecommerce delivery network. When a cross-border order shows Relay, Relay is most likely involved in the UK local delivery stage after an origin carrier, consolidator, customs broker or merchant logistics partner has moved the parcel toward the United Kingdom.

FAQ

1. How do I track my Relay package?

Enter the tracking number from your retailer dispatch message on the official Relay or retailer tracking link, or track it with 17TRACK to view available Relay shipment events.

2. Where can I find my Relay tracking number?

Your Relay tracking number is usually in the retailer dispatch email, SMS, app order page or tracking link; an order number alone may not work as a carrier tracking number.

3. What does a Relay tracking number look like?

Relay has not publicly confirmed a complete tracking-number format, so use the exact number or link provided by the retailer and avoid identifying the service from the prefix alone.

4. When will the first Relay tracking update appear?

The first meaningful Relay update usually appears after electronic shipment data is followed by physical acceptance or a depot scan; label creation alone may happen before Relay has the parcel.

5. Why is my Relay tracking not updating?

Relay tracking may pause because of missed scans, depot processing, route disruption, merchant handoff delay or a partner handoff; check the latest scan and the retailer delivery promise before escalating.

6. How long does Relay delivery take?

Relay delivery time varies by merchant service, dispatch timing, destination, address quality and operational conditions; use the delivery estimate shown at checkout or on the tracking page.

7. What should I do if Relay delivery failed?

Check the failure reason, postcode, flat number, access code and delivery instructions, then use the tracking-page option or contact the retailer if a correction or refund decision is needed.

8. What should I do if Relay says delivered but I did not receive the parcel?

Check safe places, household members, reception, neighbours and any proof of delivery first, then contact the retailer with screenshots and the Relay tracking number.

9. How do I report a lost or damaged Relay parcel?

Report a lost or damaged Relay parcel to the retailer as soon as possible, keep packaging and photos, and provide the tracking number, order number and item value evidence.

10. How do I contact Relay customer service?

Use the contact path shown on the Relay or retailer tracking page; for refunds, replacements, returns and order changes, the retailer is normally the correct first contact.

11. Is Relay the same as the retailer I bought from?

Relay is the delivery carrier or delivery-network operator, while the retailer is the seller that controls your order, payment, refund and replacement policy.

12. Can Relay track an international parcel from the origin country?

Relay may only show events after a parcel is handed to Relay or injected into its UK delivery network; origin-country events may remain under the origin carrier or merchant tracking page.

13. Why does my tracking show a partner handoff before Relay?

A partner handoff means another logistics party may have the parcel before Relay accepts it, so electronic pre-advice should not be treated as physical Relay possession.

14. Can a Relay tracking prefix prove the exact service?

No public Relay prefix-to-service map was confirmed, so the safest way to identify the service is the retailer shipping method and the live tracking result.

15. Can businesses track Relay shipments through an API?

A current public official Relay tracking API was not confirmed on the reviewed pages; businesses can use contracted Relay integrations if provided or use the 17TRACK API for multi-carrier tracking where Relay is supported.

16. Can 17TRACK change a Relay delivery address or open a claim?

No, 17TRACK can display available tracking events but cannot change a Relay delivery address, approve a refund, open a carrier claim or instruct a courier.
