Part Number Barcode Generator

Create a barcode for internal part numbers, repair labels, warehouse bins, product components, assemblies, kits, and small shop inventory. Code 128 is usually the best first choice because it supports letters, numbers, hyphens, and mixed part-number patterns.

The generator opens with a sample value and creates the barcode automatically. Replace the sample with your real part number before downloading.

When to use a part number barcode

Use part number barcodes when the label needs to identify a stock item, component, spare part, assembly, kit, or repair item quickly. A barcode helps reduce typing errors when receiving parts, picking from bins, checking out tools, or matching a physical item to an internal system.

Good part number barcode examples

PN-A04-001 for an internal part number.
PART-4472-B for a stocked component or spare.
ASM-2026-018 for an assembly or kit.
RPR-PUMP-12 for repair-shop or maintenance labels.

If your part numbers are also used as SKUs, see the SKU barcode generator. For wider warehouse workflows, see the inventory barcode generator.

Part number label workflow

Use the exact part number format your system expects.
Choose Code 128 for most part labels, or Data Matrix when the label must be very small.
Generate one real barcode and download SVG for label design software or PNG/BMP for quick printing.
Print a proof at the final label size.
Scan the proof into the same inventory, purchasing, or repair workflow that will use the label.

Label size starting points

Short part numbers: start around 45-55 mm wide for Code 128 values like PN-A04-001.
Long manufacturer numbers: use a wider label, shorten the internal ID, or test a Data Matrix code.
Small component bags: keep the barcode, human-readable text, and quiet zones clear of seams and folds.
Reusable templates: download SVG when placing barcodes into label design software.

Common part number barcode mistakes

Encoding a long description instead of a short part ID.
Changing punctuation or spacing from what the receiving system expects.
Using UPC-A for an internal part number that is not a real 12-digit retail UPC.
Cropping the blank quiet zone beside the bars.
Printing on glossy, curved, or wrinkled material without a scan test.

Frequently asked questions

What barcode type should I use for part numbers?

Code 128 is usually the best first choice for internal part number barcodes because it supports letters, numbers, hyphens, and compact values that most scanners can read.

Can I barcode a manufacturer part number?

Yes, if your workflow only needs to identify that text internally. Keep the encoded value exactly as your inventory, repair, or purchasing system expects it.

How long can a part number barcode be?

Code 128 can encode long values, but the printed barcode gets wider as the part number gets longer. For small labels, use the shortest reliable part ID or switch to a 2D code such as Data Matrix.

Should part number barcodes include spaces?

Avoid spaces unless the system that scans the label expects them. Hyphens are often easier for people to read while still keeping the encoded value predictable.
