Bin Locations and Labelling: A Practical Guide for Any Warehouse

If staff cannot find stock quickly, or cannot describe exactly where it is, almost every warehouse task suffers. Picks take longer, putaway becomes guesswork, and counts produce confusion instead of answers. Bin locations and labelling fix that. They give every storage place a name and every product a recorded home, so anyone on the team can find, check, and count stock the same way.

This guide explains how to design a simple location system, label it clearly, and keep it accurate over time. It works for a single stockroom with shelving just as well as for a larger warehouse with racking and pallet positions. You do not need software to start, although software makes good labelling even more powerful.

What Is a Bin Location?

A bin location is a named storage position: one shelf section, one bay level, one pallet space, or one drawer or tote. Bin here does not mean a physical container. It means the smallest place you want to identify in your records. Each bin location gets a unique code, and your inventory records show which products and quantities are held in which code.

The right size for a bin location depends on how you work. For small parts and retail stock, a single shelf section for one product is often ideal. For pallet storage, one pallet position is the natural unit. For mixed shelving, a location might hold a few related products, but the more products share one location, the harder picking and counting become. As a rule, if staff regularly have to hunt inside a location, the location is too big and should be split. Good bin locations underpin almost everything else in warehouse organisation, including the zone layout described in warehouse layout basics.

Designing a Location Code That Makes Sense

A good location code tells a new starter where to walk. The most readable format builds from large to small: zone or area, then aisle or row, then bay, then level, then position. For example, a code like A-03-02-2 can be read as Area A, aisle 03, bay 02, level 2. Someone holding that code can walk straight to the spot with no local knowledge.

Keep codes short, consistent, and free of confusing characters. Avoid using both the letter O and the number 0 in the same system, and avoid codes that rely on product names, because products move and locations should not have to be renamed when they do. Use leading zeros so codes sort correctly in spreadsheets and systems: 02 sorts properly, while 2 may not. Decide your format once, write it down, and apply it everywhere, including overflow and floor locations. Even a pallet space on the floor deserves a code if stock is recorded as being there. Uncoded informal storage is where inventory accuracy goes to die.

If you also create your own product codes, keep the two systems separate in your mind: location codes describe places, product codes describe items. The principles for clean product codes are covered in the guide to how to create SKU numbers, and the two systems work together every time a picker reads a pick list line: product, quantity, location.

Labelling Locations Clearly

Every location code must appear physically on the racking or shelving, at the location itself, where a person standing there can read it without crouching or climbing. Place shelf and bay labels at a consistent height and position so the eye learns where to look. For pallet racking, labels on the beam at eye level work well. For shelving, labels on the shelf edge or upright both work, as long as they are consistent.

Label materials should match the environment. Printed paper labels in plastic sleeves are fine for dry indoor shelving. Busier or colder areas need tougher laminated or plastic labels. Whatever you choose, plan for replacement: labels get knocked, faded, and peeled. Keep a small stock of blanks and a way to print or write replacements the same day, because a missing label quickly becomes a wrong putaway.

Where you use barcodes, the location label can carry a barcode of the location code so putaway and picking can be confirmed by scanning. That step, combined with product barcodes, is where accuracy jumps significantly, and it is worth reading the barcode basics for warehouses before you print anything in quantity. Badly printed or poorly placed barcodes create their own problems, as the common barcode labelling mistakes show.

Labelling Products and Inner Locations

Location labels tell staff where they are. Product labels tell them what they are looking at. Ideally every product on a shelf is identifiable without picking it up: a shelf-edge ticket with the product code and short description, or a clear label on the outer packaging facing out. When several products share a location, dividers, small totes, or separate labelled sections inside the location prevent gradual mixing.

Face labels outward and keep them current. A shelf ticket for a product that moved last month actively misleads staff. When a product is relocated, move its ticket the same day as part of the task, not as a later tidy-up. For cases and pallets, label at least two sides so the identity is visible from whichever direction staff approach.

One Product, One Home: Fixed vs Flexible Locations

Small warehouses often use fixed locations: each product has one home location, and it is always put away and picked there. Fixed locations are easy to learn, make counting simple, and suit smaller ranges well. Their weakness is wasted space when a product is out of stock and inefficient use when quantities vary a lot.

Larger or fast-changing operations often use flexible or random locations, where stock is put wherever space exists and the system records where it went. This uses space better but depends completely on disciplined recording or scanning at putaway. Without that discipline, stock is simply lost. Many small warehouses use a hybrid: fixed pick locations replenished from flexible bulk storage. Choose the model your team can actually maintain, because an ambitious system followed loosely is worse than a simple system followed exactly.

How Bin Locations Transform Counting and Picking

With coded locations, a stocktake becomes a location-by-location exercise. Count sheets can be issued by location range, each location is marked when counted, and any variance can be rechecked by sending someone to one named place. Compare that with counting by product across a whole building, where nobody can say which shelves have been covered. The location structure is what makes an organised stocktake day and routine cycle counting practical at all.

Picking improves just as much. A pick list sorted in location order becomes a walking route instead of a random tour, which directly supports better warehouse slotting decisions over time. New staff become useful on day one because the code, not memory, tells them where to go. And when a customer order cannot be fulfilled, you can distinguish quickly between stock that is truly gone and stock that is simply not where it should be, by checking the recorded location and its neighbours.

Keeping the System Accurate Over Time

Labelling is not a one-off project. Locations change, racking moves, and products come and go. Build small maintenance habits. When a location is created, moved, or removed, update the labels and the records together. During regular counts or tidies, check for missing or damaged labels and replace them on the spot. Periodically print a list of locations from your records and walk it: every code should exist physically, and every physical position should exist in the records. Empty locations are fine and should stay in the system ready for use.

Train everyone who puts stock away in one non-negotiable rule: stock goes in its recorded location, or the record is updated at the time by the agreed process, never later from memory. Most location accuracy problems come from the phrase I will update it in a minute. A minute later, the update is forgotten and the stock is effectively missing. If your process makes updating easy, on paper at the aisle end or by scanner, people will do it. If it requires a trip to the office, they often will not, so design the process for the aisle, not the office.

Getting Started in a Weekend

If your warehouse has no location system today, you can still start simply. First, divide the space into named areas and number the aisles or shelf rows. Second, number the bays and levels within each row and write your code format down. Third, label one aisle completely and record the products in those locations. Fourth, use that aisle for a week for all picking and counting, fix the annoyances you find in the format or label placement, then roll the system out row by row. Starting small proves the design before you label the whole building, and the team learns the system gradually instead of facing a warehouse-wide change in one day.

Conclusion

Bin locations and clear labelling turn a warehouse from a memory test into a system. Give every storage position a short, logical code, label it where staff can read it, identify every product clearly, and keep labels and records updated together as part of the daily work. The payoff appears everywhere: faster picking, reliable putaway, easier training, and counts that produce answers instead of arguments. It is one of the highest-return improvements any warehouse can make, and it costs mainly care and consistency.
