Bin Location Label Generator

Generate the scheme and the labels in one place

A bin location label generator is most useful when it understands the warehouse behind the label. Generic barcode tools ask for one value at a time or expect a finished spreadsheet. Here, the inputs describe the physical grid: aisle, bay, level and position. The generator expands those ranges, shows the total number of locations and previews the same field order that will appear on the printed output.

Start with one representative aisle. Set the lowest and highest bay, the level count and the number of pick faces per level. The default A01-B01-L01-P01 format is explicit enough for a new picker to understand and compact enough for common rack labels. Change the delimiter or padding only if an existing WMS or site standard requires it.

CSV is ungated; production print output is delivered by email

Download CSV gives you the complete generated code list immediately. It includes the combined location code and each component in a separate column, which matches the practical free use case: review the scheme, import it into a spreadsheet, or hand it to a WMS administrator. No account or email is required for that file.

The email gate begins at the print-ready output. Submit a work email to receive an imposed PDF with real Code 128 or QR symbols, plus the warehouse template pack. The pack contains an Excel location master, Avery sheet geometry, a naming cheat sheet and the six pre-print checks. That exchange is visible before submission: the free code data stays free, while the artifact intended for the printer arrives in your inbox.

What makes a bin code usable on the floor

Good location codes answer a route question quickly. The first field should get a person to the right zone or aisle; the next should locate the bay; the final fields should identify height and position. Keep the order consistent across every area. If a mezzanine or freezer needs a prefix, document it as a zone rather than inventing an unrelated format for that room.

Use fixed widths so A02 sorts before A10. Avoid O, I and lowercase l if you use letters, because the printed shapes are ambiguous from a forklift. Reserve unused numbers between expansion areas. A warehouse that fills every possible aisle and bay value on day one often discovers that the next extension forces an ugly suffix or, worse, a building-wide renumbering.

• Name the physical slot, not the product stored there.
• Use one delimiter and one field order across signs, labels, maps and imports.
• Keep codes short enough to read, but never so compressed that a new picker must memorise them.
• Document whether travel follows standard or serpentine order before assigning numbers.

Code 128, QR and print testing

Code 128 is the default for warehouse scanning because it is compact, widely supported and works well for structured alphanumeric codes. QR can be useful when a phone is the scanner or when future workflows need more data, but a QR symbol often needs more square area. Choose the symbology your actual devices read, not the one that looks newer.

Always test the received PDF, not a screenshot. Print at 100% scale, place a label on the rack, and scan it from the normal working angle. Check the darkest aisle and the highest level. If the printed code and decoded barcode do not match exactly, stop the run. Fifty correct labels are a useful floor test; five thousand incorrect labels are a relabelling project.
