Warehouse labelling is a foundational element of efficient warehouse management. By assigning clear identifiers to every aisle, rack, shelf, and item, companies ensure tracking and retrieving goods is faster than a morning coffee run.
In the UK’s manufacturing and logistics sectors, effective labelling systems have been linked to better inventory control, higher order accuracy, and faster picking processes. They’re the tiny fix that solves massive problems.
In this Beaverswood® industry insight report, we’ll explain the stats behind proper warehouse labelling, industry trends and best practices, plus a labelling success story from RAJA UK.

Impact of Labelling on Inventory Management and Order Accuracy
A well-implemented labelling system greatly simplifies inventory management and tracking processes, reducing the likelihood of lost or misplaced stock. This precision directly affects order accuracy. Fewer mis-picks and shipping errors occur when locations and products are marked, as workers can verify they have the right item via the label.
And it’s not just theory – real warehouses see real results.
One UK distribution centre (RAJA UK) cut picking errors just by upgrading their aisle signs and rack labels. Faster order processing, fewer mistakes. Easy win.
On the flip side, bad labelling hurts. Like £65,000 per year kind of hurts. A whopping 76% of manufacturers admit at least 10% of their goods get mislabelled annually. That means costly shipment errors, returns, and re-labelling nightmares. Worse yet, a single picking mistake can slash an order’s profitability by 13%. Yikes.
But here’s the good news: when warehouses maintain high pick accuracy (often through labelling and scanning), order accuracy skyrockets. Modern fulfilment centres with advanced systems hit 99.9% accuracy rates, underscoring how technology and labelling virtually eliminate errors.
Bottom line? Accurate labelling = fewer returns, happier customers, and a rock-solid reputation for reliability. It’s a small change with big payoffs.
Role of Barcode Labels, QR Codes, and Visual Cues in Efficiency
Barcode and QR Codes
Modern warehouses rely on various label types and designs to streamline operations, but barcodes are the most widely used method to label warehouse goods.
- 1D barcodes - The classic lines and numbers. They hold basic info (like an item code) and can be scanned quickly, even from a distance.
- 2D barcodes – E.g. QR codes. These use square patterns to store much more data – including text, links, or serial numbers – and have error correction so they can still scan if partially damaged. QR codes are gaining popularity because workers can scan them with ordinary smartphones (no special scanner needed), making them more flexible and easier to set up than regular barcodes.
Scanning barcodes is far faster and more accurate than manual data entry. It allows instant logging of inventory moves and eliminates transcription errors. Industry experts in the UK note that barcodes provide a cost-effective way to boost warehouse speed and accuracy, and their use has significantly increased as companies realise these benefits.
Visual Cues in Labelling
Colour-Coded Labels
Introducing colour cues on labels is a simple but powerful way to improve navigation and accuracy in a warehouse.
Colours can denote specific zones, aisles, or racking levels, allowing staff to distinguish sections at a glance. In daily life, we rely on standard colour coding (think of traffic lights or airport signage) to make quick decisions; similarly, in warehouses, communicating information using colour helps us make decisions quickly and more efficiently.
For example, a warehouse might print labels for Level 1 in yellow, Level 2 in green, Level 3 in blue, etc.
🟡 Level 1 = Yellow
🟢 Level 2 = Green
🔵 Level 3 = Blue
A picker looking for an item on Level 3 can immediately confirm they’re at the correct level by the label’s blue colour. In fact, full-colour summary labels placed on the first beam of a rack serve as an instant cross-check that the picker is at the right spot at the right level – preventing mistakes like retrieving stock from the wrong shelf.
Colour-coded labels effectively communicate without words, reducing confusion and training time. They allow workers to interpret label information clearly and without misunderstanding, speeding up the picking process and reducing errors.
Directional Arrow Labels
Ever looked at a rack label and thought, “Wait… is this stock here, or above… or below?” Yeah, not ideal.
That’s why directional arrow labels exist - to remove all doubt and keep picking mistakes out of the equation.
These arrow stickers (often high visibility, e.g., black on yellow) point upward or downward to show if the product is stored above or below that label on the rack. This removes any ambiguity about which shelf or pallet the code refers to. By using arrow labels, warehouses eliminate doubt in locating stock.
For instance, an arrow pointing up with the code means the item is on the shelf above that point. UK suppliers note that such directional labels help confirm that the stock location is above or below the beam, which helps eliminate picking errors.
🔼 Arrow Up? The stock’s on the shelf above the label.
🔽 Arrow Down? It’s chilling below.
In essence, arrows act as a simple visual guide so pickers don’t grab from the wrong level. This can save time and prevent errors that result from misreading location codes, especially in fast-paced operations.
Upright Labels and Summary Labels
These are specialised label designs for identifying multiple locations in one view.
🔢 Upright Labels (a.k.a Multi-Level or Totem Labels)
These are long vertical labels affixed to the rack’s upright frame. They display codes for each shelf level on that section of the rack.
They often incorporate colour bands or arrows for each level on a single vertical strip. This way, a worker standing in one spot can read all the rack’s levels without needing to climb or strain to see individual beam labels.
📜 Summary Labels (a.k.a. Split Beam or Step Labels)
These are a horizontal equivalent – a single label placed at a convenient height that lists multiple location codes (e.g. all locations in a bay or the positions above and below).
Both designs aim to make multi-level racking easier to scan and understand at a glance. They summarise multiple locations on a single label for easier identification.
By consolidating information, upright/summary labels reduce scanning errors (often, the barcodes are staggered in position to prevent a scanner from reading the wrong one) and speed up the picker’s ability to find the correct slot.
For example, a double-level label might indicate the shelf above and below in one tag, explicitly highlighting both positions. This kind of design enhances accuracy and picking efficiency by clearly showing all relevant locations.
Overall, using upright and summary labels is a best practice in tall warehouses. It improves the visibility of location codes, minimises confusion in high racking, and ensures that staff reliably pick from the intended level.
Check Digits and Verification Codes
Many UK warehouses incorporate small check digits on location labels as an extra safety step. A check digit is typically a 1-2 digit number (or letter) printed on the label that workers must confirm (by keying it in or verbally calling it) after scanning the main barcode.
This double-check ensures they are at the correct location. The logic is that if a worker scans the wrong barcode (say, an adjacent slot) by mistake, the check digit won’t match what the system expects and will alert them.
As such, check digits can be used as a double check that the correct item has been picked or put away.
This significantly lowers the chance of an error, especially in dense storage areas where barcodes are close together. Check digits add a layer of verification to the warehouse management process and are considered a best practice for high-volume operations where even a tiny error rate can have a big impact.
By combining barcodes (for automation) with visual cues like colours, arrows, and human-friendly label designs, warehouses create a robust system that boosts picking efficiency. Labels that are clear and precise mean every shelf, rack, and storage location is instantly identifiable.
This clarity translates into speed: workers spend less time searching and more time fulfilling orders. In effect, a thoughtfully designed labelling system eliminates confusion, speeds up order picking, and enhances inventory tracking.
The result is a safer, more organised warehouse where people and automated systems can operate at peak accuracy and productivity.
Industry Trends and Best Practices in UK Warehouse Labelling
Warehouses are evolving fast thanks to booming e-commerce and increasingly complex supply chains. But no matter how advanced things get, effective labelling remains at the core of warehouse best practices, and several trends are shaping how labels are used.
Standardised Location Codes and Logical Schemes
Companies invest time in designing clear location numbering systems (for aisles, bays, and levels) and labelling everything in the facility.
A correctly labelled warehouse – from floor locations to high racks – is easier for workers to identify (and therefore pick, put away or organise) stock quickly and accurately.
Best practices include labelling aisles and zones with signage, marking floor pallet spots, and ensuring every rack beam has a visible code. UK warehouses often follow a consistent format (e.g. Aisle A, Bay 01, Level 02 might be coded as A-01-02) and use that in all systems and labels. This consistency helps new staff get up to speed and reduces misplacement. For example:
📍 Aisle A, Bay 01, Level 02 ➡️ A-01-02
It is also recommended that an updated map of location codes and auditing labels be maintained periodically to replace any damaged or missing ones.
Use of Colour and Signs for Navigation
Colour coding is widely embraced as a best practice. Many UK facilities assign colours to warehouse zones or levels to create a visual map. For example, you could apply light green labels for picking areas and light blue labels for bulk storage to differentiate sections.
🟩 Light Green = Picking zones
🔷 Light Blue = Bulk storage
The consensus is that “clearly defined areas” with consistent signage and labelling will reduce picking errors and the time it takes to pick during peak periods, yielding gains in productivity.
Large, well-placed aisle markers (often end-of-rack signs) are another best practice so that workers and forklift drivers can see where they are from a distance. In short, visual management through labels and signs is key to an orderly, efficient warehouse.
Durable, Scan-Friendly Labels
A label is only useful if it remains legible and scannable. Therefore, best practices in the UK include choosing the right label materials for the environment.
❄️ Magnetic or specialised freezer-grade labels are used in cold storage or unheated warehouses, so they won’t peel off in low temperatures.
💪 Laminate or polyester labels resist wear in dirty or abrasive environments. Investing in these hard-wearing labels pays off by avoiding the need for frequent relabelling.
🧲 Frequently moving locations? Magnetic labels can be repositioned at any time.
UK labelling providers emphasise that a hardwearing solution will last longer and save money in the long run with fewer replacements required.
It’s also important to print labels with high contrast for readability - typically black text/barcode on a white or yellow background. Another consideration is ensuring barcodes are scannable from the intended distance and angle (sometimes using larger font or codes for higher placements).
The goal is to ensure nothing impedes a quick scan or visual read of the label when needed.
Integration with Warehouse Management Systems (WMS)
Labelling strategies work best when tied into digital systems. Each location label’s code is recorded in a WMS, and each product’s barcode is linked to its database record. Real-time scanning of these labels during picks, put-aways, or cycle counts keeps the WMS accurate.
Many UK warehouses are equipping staff with mobile devices or scanners – in fact, about 73% of surveyed companies plan to equip staff with advanced visibility and barcode scanning technologies.
This reflects a trend toward technology-driven warehouses where scanning a label instantly triggers inventory updates, pick confirmations, and so on.
Overall, good labelling and WMS software synergy lead to highly efficient operations. For example, Black Bear Fulfilment (a UK 3PL) credits its 99.97% order accuracy to such a system where robust labelling and software guide the process.
Automation and Futureproofing
Warehouses aren’t just for people anymore – robots, automated guided vehicles, (AGV), and automated systems are moving in. And guess what? They need consistent and exact labels/codes to find their way.
If a robot is tasked with picking items, it might use barcodes and QR code labels on racks to orient itself. Thus, the need for precise and reliable labelling becomes even more critical with automation.
UK warehouses are increasingly planning for this by standardising labels (so automation can read them) and sometimes adding machine-readable signage (like QR codes that AGVs can scan).
Another emerging trend is the use of RFID tags and electronic labels (e-ink displays). RFID labels allow entirely scan-free identification (a reader can sense the tag from a distance without a direct line of sight), enabling faster inventory checks and even automated tracking of goods moving through portals. They also carry more data. However, RFID is still a bigger investment and not as widely adopted, partly due to cost.
Electronic shelf labels (using e-ink screens), already popular in retail, are being tested in warehousing. These digital labels can update wirelessly (for example, to reflect a new product SKU or updated stock info) and promise fewer labelling errors and extremely fast reorganisation of inventory slots. They also support sustainability by reducing paper use. While not yet common, such technologies represent the future of warehouse labelling – flexible, instantly updateable location markers that keep pace with dynamic inventory.
UK companies focused on innovation are keeping an eye on these trends to stay ahead.
Regulatory and Safety Labelling
In manufacturing warehouses, especially for food, pharmaceuticals, or chemicals, labelling carries an extra weight for compliance.
Marking batch numbers, expiry dates, and hazardous materials is not just best practice but often a legal requirement. Barcode and QR code labels play a big role by linking to traceability data. Modern label systems in the UK often incorporate fields for these details (and scanning a code can pull up safety instructions or provenance info).
Additionally, warehouses are labelling for health and safety - for example, load capacities on racking, “drive-in” lanes, or floor labels to mark pedestrian paths and forklift lanes. These practices ensure safety and efficiency go hand in hand. A well-labelled warehouse will indicate not only where items are but also how to handle them (e.g., “Fragile” or “This Way Up” labels on packages, etc.).
The trend in UK operations is toward comprehensive labelling covering operational info, safety, and quality data, thereby supporting overall organisational performance and compliance.
In summary, UK industry best practices encourage a holistic labelling strategy: durable, standardised labels on every storage location; colour and signage to simplify navigation; verification mechanisms like check digits; and integration with technology for real-time management.
By following these practices, warehouses can significantly increase productivity and achieve near-error-free operations, even at scale.
UK Case Study: Labelling Success Story
Want proof that good labelling = big results? Here’s a real-world example from the UK illustrating how improved labelling translates to operational gains.
🚀 The Challenge
RAJA, a leading packaging supplier, opened a 260,000 sq ft distribution centre in England – a massive space with tons of inventory, and a team of 60+ pickers needing to work fast and efficiently.
🔍 The Fix
They invested in clear aisle signage, rack location labels, and document holders throughout the facility from day one.
🎯 The Results?
According to RAJA UK’s Purchasing Director, these improvements “have...contributed to making our workplace more productive for order picking and processing”, as “pickers can see easier where they need to be in the warehouse and identify quickly where they should be working.”
In other words, clear labels and signs help direct the 60+ pickers so they spend minimal time searching. RAJA also reported a measurable drop in picking errors after implementing the labelling system.
This case underlines that workers are empowered to be faster and more accurate when a warehouse is well-labelled and organised. The benefits RAJA saw – higher productivity and fewer errors – were directly tied to their investment in “visual and organisational aids” to “maximise productivity”, among which labelling was critical.
This case study demonstrates that better labelling yields real operational improvements. The impact is evident, from time savings to error reduction. It isn’t just about putting up stickers - it’s about engineering an information system in the physical space of the warehouse that guides both people and technology.
For RAJA, this meant scaling up a new facility with high efficiency. Many other UK businesses have similar stories where barcoding and labelling initiatives led to gains in accuracy, throughput, and even safety (for example, reducing chaos and collisions by having clear signs and thus less wandering).
Summary
In conclusion, warehouse labelling is a critical enabler of efficiency in the UK’s manufacturing and logistics sectors. A good labelling system reduces mistakes and accelerates operations by improving inventory visibility and guiding order pickers. It creates a warehouse environment where anyone can find what they need in seconds by following the labels – making the warehouse self-explanatory.
As the above research and example show, investing in proper labelling (from barcodes and QR codes to colour codes and arrows) pays dividends in accuracy, speed, and cost savings. In an era of high customer expectations and tight supply chain schedules, picking efficiency and inventory management improvements give companies a competitive edge.
Warehouses that adopt modern labelling best practices and evolve with new labelling technologies are well-positioned to handle growing volumes while maintaining stellar accuracy and service levels.
