“Behind the large boxes” is a location that works until the boxes move. Small stockrooms often begin with this kind of informal geography because everyone knows the room. As more products arrive, however, familiar landmarks become unreliable and an ordinary stock search turns into a tour of several shelves.
A bin address gives a physical place a stable name. It does not need to describe the product stored there, and it should not depend on remembering who last rearranged the room. Its job is to make a recorded location lead another person to the correct place.
Name places independently of products
Start by dividing the room into obvious sections that can be identified from the entrance. A section might be a shelving run or a separate storage cabinet. Give each section a short, distinct identifier that is easy to read and say aloud.
Within each section, number shelves and positions in a consistent direction. Decide whether shelves are counted from the bottom or the top and use that rule throughout. A label that combines section, shelf, and position should point to one place rather than several similar possibilities.
Avoid product names in the permanent address. “Large blue folders” stops being useful when that bin holds envelopes. The address should remain attached to the place, while the stock record describes which product currently occupies it.

Make the physical labels unambiguous
Place labels consistently so people know whether a label refers to the space above, below, or beside it. A row of labels at irregular positions can produce mistakes even when every code is technically unique. Show the relationship between label and storage position clearly.
Use lettering that can be read from the normal picking position. Test it under the room’s usual lighting, including shadows cast by stocked shelves. Avoid combinations that are hard to distinguish quickly, such as nearly identical letters and numerals in a decorative typeface.
Do not use color as the only identifier. Color can reinforce a section, but the written address should remain sufficient on its own. Replace labels that become hidden behind overhanging cartons instead of expecting people to infer the location from its neighbors.
Keep physical capacity separate from naming. A bin address is not permission to overload a shelf or store heavy goods at an unsuitable height. You can also visit Colourpop for more reading.
Connect the address to everyday stock movements
A location system becomes useful only when product movements update the record. Begin with a manageable part of the stockroom, assign addresses, and verify the products in those positions. Avoid creating a beautifully labeled room whose stock records still describe the old landmarks.
For each stocked position, maintain a short practical record:
- The bin address exactly as it appears on the shelf.
- The product identifier and variant assigned to that position.
- Any additional location holding the same product.
- Any restriction that affects picking from that stock.
If a product occupies more than one bin, record all active locations. Do not squeeze extra cartons into an unrecorded gap and rely on someone remembering the overflow. A separate overflow address is more reliable than a note saying “more nearby.”
When moving goods, update the destination and the source as one movement. Leaving the old address active can send the next picker to an empty shelf. If the move must pause, use an identified temporary location rather than allowing unplaced stock to disappear between two accurate-looking records.
Prove the system with unfamiliar searches
Give someone who did not design the scheme a product reference and its recorded address. Let them find it without hints. Notice whether they can identify the correct section, understand the shelf numbering, and distinguish the intended bin from the adjacent space.
Then test a product that has overflow stock. The person should be able to find the additional quantity without opening unrelated cartons or asking who received the last delivery. Difficulty at this stage usually points to an unclear record or label rather than a need for more elaborate codes.

When the room is rearranged, decide whether physical addresses will move with shelving or be reassigned to fixed positions, and apply that decision consistently. Update affected records before normal picking resumes. A brief check after the move prevents the old room from surviving invisibly in the stock list.
