POST Luxembourg Tracking

POST Luxembourg tracking lets you follow a parcel, registered letter, or EMS shipment from the moment it is accepted at a Luxembourg post office until it reaches your door or a PackUp pickup point. POST Luxembourg, the national postal operator of the Grand Duchy, handles domestic mail, inbound e-commerce parcels, and outbound international items under the Universal Postal Union framework it has belonged to since 1874. Paste your tracking number into the tracker at the top of this page to see the latest scan, the current status, and the estimated stage of delivery.

This guide explains exactly what a POST Luxembourg tracking number looks like, what each tracking status means, how long delivery takes inside Luxembourg and abroad, how PackUp lockers and post offices fit in, and which marketplaces hand parcels to POST for the last mile. Every number format and figure below is drawn from POST Luxembourg and Universal Postal Union sources.

POST Luxembourg Tracking Number Format

A POST Luxembourg international tracking number is a 13-character code that follows the Universal Postal Union S10 standard: two letters, nine digits, and the country code LU at the end. A typical example is RR123456789LU, where "RR" is the service indicator, the nine digits are the serial number plus a check digit, and "LU" identifies Luxembourg as the country of origin.

The two opening letters tell you the service class. The first letter signals the product family (for example, R for registered items, C for ordinary parcels, E for EMS express, L for some letter-post products), and the second letter is usually a sequence character within that family. The final "LU" is fixed for any item that originates with POST Luxembourg, which is why it is the quickest way to confirm a number really belongs to the Luxembourg post rather than a foreign carrier.

Not every POST Luxembourg shipment carries an S10 number. Purely domestic parcels and PackUp items can move under a longer internal barcode that does not end in "LU" and does not follow the 2-9-2 pattern. If your number was issued by the online shop rather than by POST, it may be an order reference, not a trackable AWB; the order ID identifies your purchase in the retailer's system, while the tracking number identifies the physical parcel in the postal network. When in doubt, the trackable number is the one printed on the postage label or shown in the shipping confirmation email, usually 13 characters ending in LU for international items.

You can verify any POST Luxembourg number on the official Track and Trace tool at post.lu as well as in the tracker on this page, which also follows the item once it is handed to a partner carrier abroad.

POST Luxembourg Tracking Number Example

The table below shows the number formats you are most likely to see on POST Luxembourg items. The service-indicator meanings follow the UPU S10 standard, which assigns letter ranges to product families. Treat the first-letter groupings as the common convention: a prefix points to a product family but does not, on its own, guarantee a specific premium service.

Only the S10 numbers ending in LU are guaranteed to resolve on the international tracking network. If your small-packet item shows no movement on the POST system, it may still be travelling under the origin carrier's number until it is handed to POST inside Luxembourg.

POST Luxembourg Tracking Status Guide

POST Luxembourg tracking statuses describe each scan event from acceptance to final delivery, and the same vocabulary applies whether your item is domestic registered mail or an inbound international parcel. The table below maps the statuses you will most often see to what is actually happening to your parcel.

What to Do If a POST Luxembourg Parcel Is Delayed or Not Updating

A POST Luxembourg tracking number that has not updated for several days is usually waiting at customs or between carrier systems, not lost. International parcels can sit at an office of exchange or in customs clearance for a few working days, and inbound e-commerce small packets often show no POST scan at all until the item physically reaches Luxembourg, because they travel under the origin carrier's number first.

Before contacting support, give a domestic item 2 to 3 working days and an international item the full delivery window for its destination. If the status still has not moved, check that you are using the correct number (the 13-character LU code, not the shop's order ID), and confirm whether the parcel has switched to a partner carrier such as DHL Express tracking for the express leg. Items addressed to a PackUp locker only show "available for pickup" once they have been deposited, so a parcel marked out for delivery may simply not have reached the locker yet.

If a registered or EMS item is genuinely overdue, POST Luxembourg can open an inquiry; you can reach customer service on 8002 8004 from inside Luxembourg or +352 2424 8004 from abroad, Monday to Friday. Keep your posting receipt, because the barcode on it is what an inquiry or a lost-item claim is based on.

POST Luxembourg Services and Delivery Times Compared

POST Luxembourg offers a tiered range of mail and parcel products, from economy letter post to next-day EMS and DHL Express, all trackable through the same Track and Trace tool. The table summarises the main services and their realistic delivery windows; treat all times as estimates, since only DHL Express carries a guaranteed delivery commitment.

For sending abroad, POST positions EMS as its fastest in-house option and resells DHL Express Easy for time-critical shipments, so a parcel to a neighbouring market such as Belgium, served domestically by Bpost tracking, can move in a couple of days by standard parcel or overnight by express.

POST Luxembourg Delivery and Transit Times by Destination

Inside Luxembourg, POST Luxembourg reaches every commune in the country, and national parcels generally arrive within 2 to 3 working days. Delivery covers Luxembourg City and the surrounding cantons including Esch-sur-Alzette, Differdange, Dudelange, Ettelbruck, Diekirch, Wiltz, and Echternach, with PackUp lockers and post offices filling the gaps where home delivery is missed.

Cross-border transit times depend heavily on the destination and on customs. Parcels to the immediate neighbours, France via Colissimo tracking, Germany via Deutsche Post tracking, and Belgium, usually take about 2 to 3 working days. Shipments to the rest of Europe typically take 3 to 6 working days, while destinations in North America, Asia, and the southern hemisphere range from roughly 5 to 10 working days for standard parcels, faster with EMS. POST Luxembourg states there are no guaranteed transit times for ordinary international items; only DHL Express carries a delivery commitment.

POST Luxembourg Returns, PackUp Pickup, and Import Forwarding

POST Luxembourg's PackUp network is the backbone of its parcel pickup, drop-off, and returns service, with 184 lockers available to Amazon Prime members in 2026 and over a hundred staffed and self-service stations nationwide. More than 90% of PackUp lockers are accessible 24 hours a day, seven days a week, which makes them the default choice for receiving and returning e-commerce parcels in Luxembourg.

With PackUp you can have a parcel delivered to a locker or collection point with flexible hours instead of your home address, and you can drop off prepaid returns at the same stations. A complementary service, PackUp Import, assigns you a delivery address in France or Germany that you give to retailers who do not ship directly to Luxembourg; POST then collects the parcel abroad and forwards it to the PackUp station or collection point of your choice. This is especially useful for orders from retailers that quote French or German delivery only.

For lost or damaged items, keep the posting receipt and packaging, and lodge an inquiry with POST Luxembourg; registered and insured items qualify for a claim based on the service conditions and the declared value.

Which Countries Does POST Luxembourg Deliver To?

POST Luxembourg delivers to virtually every country through the Universal Postal Union network and its EMS cooperative links, reaching more than 170 countries with express service and the wider UPU membership with standard mail and parcels. Domestically it covers the entire Grand Duchy, from Luxembourg City and the industrial south around Esch-sur-Alzette to the rural north around Wiltz and Clervaux.

Because Luxembourg sits inside the European Union and the Schengen area, parcels to other EU members move without customs formalities, which keeps transit fast across the bloc. Outside the EU, items pass through Luxembourg's office of exchange, are handed to the destination postal operator, and clear customs in the receiving country.

Representative destinations grouped by region include:

• Domestic: all communes of Luxembourg, including Luxembourg City, Esch-sur-Alzette, Differdange, Dudelange, Ettelbruck, and Echternach.
• Europe (EU and neighbours): France, Germany, Belgium, the Netherlands, Spain, Italy, Portugal, Austria, Poland, and Ireland.
• Wider Europe (non-EU): the United Kingdom, Switzerland, Norway, Iceland, Serbia, Ukraine, and Turkey.
• North America: the United States and Canada.
• Asia Pacific and beyond: China, Japan, Australia, and other EMS-linked markets.

POST Luxembourg Cross-Border Customs and International Handoff

Customs declarations are not required for parcels sent between European Union member states, but any item leaving the EU needs a CN22 or CN23 customs form. POST Luxembourg explains the rule plainly:

"Customs declarations are not required for letters or parcels sent between EU member states." (POST Luxembourg, Customs duties and formalities, 2025.)

For shipments outside the EU, the form depends on weight and value: a CN22 is the simplified declaration for lighter, lower-value items, while a CN23 is the detailed declaration required for heavier parcels or those above the value threshold (about 250 euros). The declaration lists the contents, value, and origin so customs in the destination country can assess any duty or VAT, which is normally paid by the recipient before release.

On the tracking side, an outbound parcel is scanned as it leaves Luxembourg's outward office of exchange, then again when it arrives at the destination country's inward office of exchange, at which point the local postal operator takes over the last mile. This handoff is why an international POST Luxembourg number sometimes stops updating on the POST system and continues on the partner carrier's tracking instead. The Universal Postal Union frames the S10 number as the key that links these scans together:

"S10 specifies a thirteen-character identifier for use in the accounting and tracking of international postal items." (Universal Postal Union, S10 standard.)

What Is POST Luxembourg?

POST Luxembourg is the national postal and telecommunications operator of the Grand Duchy of Luxembourg, tracing its roots to the state postal administration founded in 1842. It issued its first postage stamp in 1852 and became a founding member of the Universal Postal Union in 1874, giving it more than 150 years of continuous international postal cooperation.

The modern enterprise was created on 10 August 1992, when a Luxembourg law established the Entreprise des Postes et Telecommunications (EPT) as a publicly owned company with administrative and financial autonomy, separating day-to-day operations from direct state administration while keeping the state as full owner. Today POST Luxembourg operates as a group spanning postal, courier, financial, and telecom services.

Its physical network includes more than 100 sales outlets such as post offices and partner counters, alongside roughly 1,108 public yellow letterboxes for posting mail as of 2023. For parcels, the PackUp locker and pickup network extends that reach with 24/7 self-service points across the country, positioning POST as the dominant last-mile parcel operator inside Luxembourg.

POST Luxembourg Marketplace Collaborations

POST Luxembourg is the delivery and pickup partner behind most online shopping in the Grand Duchy, handling parcels from both the national marketplace and the big international platforms. The clearest example is the government-backed national marketplace Letzshop, launched in September 2018 and run by GIE Luxembourg for Shopping, which gathers hundreds of local retailers and more than 387,000 items in one catalogue and integrates POST Luxembourg delivery, including PackUp pickup, for orders placed on the platform.

International marketplaces lean on the same network for the last mile. Amazon (through Amazon.fr and Amazon.de) ships extensively into Luxembourg, and in 2026 Amazon Prime members gained the option to receive orders at 184 PackUp lockers across the country, a direct POST Luxembourg collaboration. Shoppers tracking those deliveries can follow them with Amazon tracking until the parcel lands in a PackUp locker. Fashion platform Zalando is another heavy shipper into Luxembourg, and its parcels can be followed with Zalando tracking once a number is issued.

Because many Luxembourg shoppers also buy from China-based marketplaces, POST handles a steady flow of inbound small packets from AliExpress, Temu, and Shein, which arrive under an origin-carrier number and are scanned into the POST system on entry for final delivery or PackUp pickup. Where a cross-border order is shipped express, it may be completed by a partner such as DHL Express rather than by POST's own carriers, which is why the tracking sometimes switches networks mid-journey.

For everyday domestic and EU orders, POST Luxembourg remains the operator that physically brings the parcel to your letterbox, your post office, or your nearest PackUp locker, with the same 13-character tracking number tying the whole journey together.
