The Complete Guide to GLS Tracking: Everything You Need to Know About Shipping with GLS

If you’ve ever ordered a package that was shipped through GLS, you’ve probably found yourself wondering how to track it, what to expect during delivery, and what to do if something goes wrong. GLS is one of Europe’s largest parcel delivery networks, operating in more than 40 countries and handling hundreds of millions of shipments every year. Whether you’re a business owner choosing a logistics partner or a customer waiting on a delivery, understanding how GLS works can save you a significant amount of time, frustration, and money.

This guide covers everything from the basics of GLS tracking to tips for businesses looking to integrate GLS into their shipping workflow. By the end, you’ll have a thorough understanding of the service, its strengths, its limitations, and how to get the most out of it.

What Is GLS and How Did It Get Started?

GLS stands for General Logistics Systems. It began as a subsidiary of Royal Mail, the British postal service, and over the decades it grew into a powerful, independent logistics network that now spans most of Europe and has partnerships that extend its reach into North America and Asia. The company was eventually acquired by the American parcel delivery group GeoPost, a subsidiary of La Poste, the French national postal service.

What makes GLS distinctive is its hub-and-spoke model combined with a network of independent depot partners. Unlike courier services that own every piece of infrastructure themselves, GLS works with local and regional partners who operate under the GLS brand. This gives the company remarkable geographic reach without requiring the enormous capital investment that complete self-ownership would demand. It also means that the quality of service can vary slightly depending on which local partner is handling your shipment, something worth keeping in mind if you’re evaluating GLS as a business shipping solution.

How GLS Tracking Works

One of the most frequently searched topics related to GLS is tracking. Customers want to know where their package is, when it will arrive, and whether they need to be home to receive it. The GLS tracking system is built around a unique parcel number that is generated when a shipment is registered in the system.

When you receive a shipping confirmation from a retailer or sender that has used GLS, you’ll typically be given a tracking number that looks something like a string of digits, often preceded by a prefix identifying the country or service type. You can enter this number on the GLS website for your country — for example, gls-group.com, gls-germany.de, or the relevant national portal — and you’ll see a timeline of events showing where your package has been and where it is now.

The tracking events you’ll typically see follow a logical progression. First, a “data received” or “label created” status appears, which simply means the sender has registered the shipment but hasn’t handed it over to GLS yet. Once the parcel is physically collected or dropped off, it enters the GLS network and you’ll start seeing active scan events. These include arrival and departure at sorting depots, transfer between hubs, and eventually a “parcel out for delivery” notification, which means it’s on a delivery vehicle heading to your address.

GLS also offers a service called FlexDeliveryService in many markets. If you’re signed up for this (often through a notification email or SMS), you can redirect a parcel to a GLS ParcShop, change the delivery date, or authorize the driver to leave the package in a safe place without a signature. This kind of flexibility has become increasingly important to customers who aren’t always home during working hours.

Understanding GLS Delivery Attempts and What Happens Next

One of the most common points of confusion — and frustration — with parcel delivery in general is what happens when a delivery attempt fails. With GLS, if no one is home and you haven’t pre-authorized an alternative delivery option, the driver will typically leave a delivery notification card and return the parcel to the local depot. In most cases, GLS will make a second delivery attempt on the following working day.

If two or three delivery attempts fail (the exact number depends on the country and the specific service type), GLS will either leave the parcel at a GLS ParcShop for you to collect or return it to the sender. The parcel is usually held at the ParcShop for seven business days, after which it’s sent back if uncollected.

It’s worth noting that GLS ParcShops are not GLS-operated stores. They’re typically existing retail locations — newsagents, petrol stations, small supermarkets — that have signed up to act as collection and drop-off points. The network is extensive, with tens of thousands of ParcShops across Europe, so there’s usually one within reasonable distance of most addresses.

If you’ve missed a delivery and received a card or notification, the fastest way to arrange collection or rebooking is through the GLS tracking portal or by calling the local GLS customer service line. Trying to intercept a parcel mid-route is generally not possible for security reasons, but rerouting to a ParcShop before a second attempt is often an option.

GLS Services for Businesses: What’s Available?

GLS isn’t just a consumer-facing delivery service. A large portion of its business comes from e-commerce retailers, manufacturers, and distributors who ship high volumes of parcels on a regular basis. For these customers, GLS offers a range of tailored services.

The standard GLS Business Parcel service is designed for B2B deliveries — packages sent from one business to another. These shipments are typically addressed to commercial premises where someone is reliably available during business hours, which makes the delivery process more straightforward than residential deliveries.

For e-commerce companies shipping to consumers, GLS offers its ShopDeliveryService, which routes parcels to ParcShops near the recipient’s address rather than attempting home delivery. This is particularly useful for businesses whose customers are frequently not home during the day. It reduces failed delivery attempts, which cost money, and it gives customers the convenience of picking up their parcel when it suits them.

GLS also offers guaranteed delivery services with specific time windows. The ExpressService and Business ExpressService offer next-day or time-specific delivery, which carries a premium but is essential for certain types of shipments. There are also options for evening delivery in select markets, which addresses the recurring problem of residential customers being unavailable during standard delivery hours.

For businesses shipping high-value goods, GLS offers enhanced insurance options, and for shipments requiring proof of delivery beyond a standard scan, there are services with e-signature capture.

International shipping is a major part of the GLS offering. Through its European network and partnerships, GLS can deliver across most of the continent with relatively competitive transit times. The EuroBusinessParcel service, for example, provides coverage across a large number of European countries, with tracking throughout. For businesses that export regularly across borders, this kind of integrated cross-border service is considerably more convenient than piecing together shipments through multiple national carriers.

How GLS Compares to Other Parcel Carriers

When businesses are evaluating logistics partners, they inevitably compare GLS to DHL, DPD, UPS, FedEx, and other major players. Each carrier has its strengths and weaknesses, and the best choice depends heavily on your specific situation.

GLS tends to be competitive on price, particularly for European cross-border shipments. Its extensive ParcShop network is a genuine differentiator, especially for e-commerce businesses whose customers value flexible pickup options. The company’s integration with national postal services in some markets also gives it broader reach in rural or hard-to-access areas.

Where GLS sometimes falls short, at least in the perception of some customers and businesses, is in the consistency of its service. Because the network relies on independent depot partners, the experience can vary from one region to another. A business shipping from a major German city might have an excellent experience, while one shipping from a smaller market might encounter slower transit times or less reliable tracking updates.

Tracking granularity is another area where GLS has historically lagged behind some competitors. DHL, for example, offers very detailed real-time tracking with frequent updates, while GLS tracking can sometimes show large gaps between scan events. The company has been investing in improving this, including through the expansion of its digital notification systems, but it’s worth being aware of if granular tracking is important to your business or your customers.

Customer service accessibility is also a common talking point. GLS operates primarily through its national subsidiaries, and the quality and responsiveness of customer service varies by country. In general, businesses with volume contracts tend to have access to dedicated account management, while individual consumers may find it harder to get direct support.

Tips for Getting the Best Experience with GLS

Whether you’re a business integrating GLS into your fulfilment operation or an individual tracking a single parcel, a few practical habits can make the experience significantly smoother.

If you’re a business, invest time in your API integration. GLS offers developer APIs in most markets that allow you to automate label creation, tracking updates, and returns management. Setting this up properly from the start eliminates a lot of manual work and reduces errors. Many e-commerce platforms — Shopify, WooCommerce, Magento, and others — have existing GLS plugins that can simplify this process.

Make sure your shipping addresses are clean and accurate. Address errors are one of the leading causes of delivery failures and delays, and they’re almost entirely preventable. GLS, like all carriers, relies on the address data you provide. An incorrect postcode or a missing apartment number can result in a parcel sitting in a depot while the carrier tries to figure out where it should go.

For businesses, take advantage of the returns infrastructure GLS offers. Returns management is increasingly important in e-commerce, and GLS has invested in making it easier for businesses to offer prepaid returns labels, drop-off returns at ParcShops, and consolidated returns shipping. A smooth returns process is a meaningful part of the customer experience and can directly affect repeat purchase rates.

For consumers waiting on a parcel, register for GLS notifications if the retailer hasn’t already set them up on your behalf. Many national GLS portals allow you to enter your tracking number and sign up for email or SMS updates. This means you’ll know as soon as the parcel is out for delivery, giving you time to make arrangements if you won’t be home.

If your parcel appears to be delayed or stuck at a depot for an unusual amount of time, the first step is to check the GLS tracking page for any status messages. Sometimes a parcel is held due to a customs issue, an address query, or a weather or operational disruption. If the tracking shows no movement after several business days, contact GLS customer service or reach out to the sender, who often has more leverage and access to resolve issues through their business account.

GLS Sustainability Efforts: What the Company Is Doing About Its Environmental Impact

Logistics is an industry with a significant environmental footprint. The movement of parcels across thousands of kilometres, using diesel vans for last-mile delivery, is a major source of carbon emissions. GLS has acknowledged this and has been making moves to reduce its environmental impact, though the scale and ambition of these efforts are still evolving.

The company has been expanding its fleet of electric delivery vehicles, particularly for urban last-mile deliveries where EVs are most practical. In several European cities, GLS has also been piloting cargo bike delivery for the final leg of the journey — a zero-emission option that also avoids traffic congestion and the complications of parking that can affect van-based delivery in dense urban areas.

GLS has committed to targets around reducing its carbon emissions and has published sustainability reports outlining its progress. Like most logistics companies, it also offers carbon-neutral shipping options for businesses that want to offset the emissions from their shipments.

Whether these efforts are sufficient in the context of the broader climate challenge is a legitimate question, and the logistics industry as a whole faces scrutiny on this front. But for businesses that have sustainability commitments of their own, GLS’s direction of travel is relevant to consider when choosing a carrier partner.

Common Questions About GLS

Many people arrive at the GLS tracking portal or customer service with the same questions, so it’s worth addressing a few of the most common ones directly.

Can I change the delivery address after a parcel has been shipped? In most cases, no. Once a parcel is in the GLS network, the delivery address is fixed for operational reasons. What you can sometimes do is redirect it to a ParcShop near the original delivery address, using the FlexDeliveryService options if they’ve been activated for your shipment.

What happens if my parcel is damaged? You should document the damage with photographs as soon as possible and report it to the sender. It’s the sender who has the contract with GLS and who can file a damage claim. If you purchased additional insurance through the retailer or through GLS directly, this will influence the compensation process.

How long does GLS take to deliver? Domestic delivery within most European countries takes one to two business days. Cross-border European deliveries typically take two to five business days depending on the countries involved and the service level chosen. These are standard transit times and don’t account for delays caused by customs, public holidays, or operational disruptions.

Is GLS available outside Europe? GLS has a limited but growing presence outside Europe, primarily through partnerships rather than owned infrastructure. In the United States, GLS acquired a US-based regional carrier, and it has partnerships in other markets. However, its core strength remains European parcel delivery.

Final Thoughts

GLS has earned its place as one of Europe’s major logistics players through a combination of competitive pricing, a strong ParcShop network, and solid cross-border coverage. It’s not perfect — no carrier is — and the quality of experience can depend on the specific depot and local partner handling your shipment. But for businesses looking for a capable European parcel carrier, and for consumers trying to understand and manage their deliveries, GLS offers a solid foundation.

The key to a good experience with GLS, as with any carrier, is knowing how the system works, using the available digital tools, and acting quickly when something doesn’t go as expected. With the information in this guide, you’re well equipped to do exactly that.
