Batch Barcode
Bulk Barcode Generator
Create multiple barcode labels at once with our bulk barcode generator. Import Excel or CSV, paste an existing list, or generate a numbered sequence. Preview your labels, check the source values, then print online or download the batch as a ZIP. Start with your existing product, inventory or asset IDs.

Production guide
How to use the bulk barcode generator
A bulk barcode generator turns a collection of identifiers into separate barcode labels in one workflow. Each source value becomes the data encoded in a barcode, so preparing the list correctly matters as much as choosing the label layout. Begin with a small sample, confirm that the scanned values match your records, and then prepare the remaining labels. Keep the original source file so you can check the output or reproduce the batch later.
Choose your bulk barcode input
- Excel or CSV for existing product catalogs and asset registers.
- Pasted lists for short jobs with one identifier per line.
- Numbered sequences for new ranges of internal IDs.

Import barcode data from Excel or CSV
Prepare a spreadsheet with one barcode value per row. Keep identifiers such as 000123 as text so spreadsheet software does not remove leading zeroes or convert long numbers into scientific notation. The downloadable import template includes Barcode Data, Top Note and Bottom Note columns. Put the encoded values in the Barcode Data column of the template so the importer can identify them reliably. Product names and label notes should stay separate unless they are intentionally part of that value. Compare several imported records with the source spreadsheet, including the longest identifier and values containing punctuation.

Paste a list or create sequential barcodes
For a short list, paste one identifier per line. The generator trims surrounding spaces, skips empty entries and removes duplicate values. Review the resulting count before generation; repeated input rows will not produce extra copies of a label. For new internal identifiers, use a numbered sequence such as ASSET-0001 through ASSET-0100. Set the prefix, starting number, count and padding to match your register. Review the first and last values and confirm that the range does not overlap with IDs already in use. Sequential values are useful for internal asset tracking, but they should not replace product identifiers assigned by another system.

Choose a format and review your barcode labels
Select the barcode format required by the system that will read the labels. Code 128 can suit internal identifiers containing letters and numbers, while other workflows require different formats. Follow the receiving system’s requirements rather than choosing a format only because its preview looks compact. Review validation messages and correct the affected source values. Check short and long identifiers: a layout that fits a brief SKU may need adjustment for a longer value. Optional label text should remain readable and separate from the bars.

Print your labels or download a ZIP
Once the sample is correct, choose the output that fits your workflow. Print online when you are ready to produce labels, or download a ZIP to organize and hand off the barcode files. Before a full print run, test a small selection at the final label size. Match the printer’s media settings to the label dimensions and avoid scaling that distorts the barcode. Scan printed samples with the device you will actually use, compare decoded values with source records, and check the final output count before distribution.
Generate barcodes in bulk for inventory and assets
Use the bulk barcode generator when you have a list of records that need consistent labels. For inventory, start with the SKUs or stock IDs used in your catalog so each scan can be matched to a record. For equipment tracking, use the asset IDs maintained in your register. Decide whether a label represents a product type or an individual item: several units may share a SKU, while individually tracked equipment needs a distinct asset ID. The batch barcode generator renders the values you supply; it does not create the inventory records that connect those values to your products. Keep that mapping in your business system.
Avoid common bulk barcode generation errors
Missing leading zeroes usually begin in the source spreadsheet. If 000123 has already become 123, changing the barcode appearance will not restore the identifier; correct the source data and import it again. Unexpected scan results can come from the wrong column, altered values or an unsuitable format. Compare the decoded value with the source record instead of relying only on the printed text. If a label looks clear on screen but fails after printing, check the final size, contrast, blank space around the barcode and printer settings. Resolve sample failures before printing the rest of the batch.
Before you print or export your barcode batch
- Confirm that the source column contains the intended barcode values.
- Preserve leading zeroes and review long numeric identifiers.
- Account for duplicate values being removed from the input list.
- Resolve validation errors before preparing the final output.
- Scan sample labels at their final printed size.
- Compare the output count with the number of records you intended to label.
Bulk barcode generator FAQ
Can I generate barcodes from Excel or CSV?
Yes. Use the import template and place your identifiers in the Barcode Data column, then import the file. Use one value per row and keep identifiers as text when leading zeroes matter. The template’s optional Top Note and Bottom Note columns add label text without changing the encoded value. Check the imported sample before exporting.
How many barcodes can I generate in one batch?
The limit depends on your plan. Check the limit shown in the generator before importing a large file or creating a sequence. Start with a small sample to validate your data and layout, then keep the complete job within your plan’s batch allowance.
Can I print the batch or download all the barcodes?
You can print labels online or export valid barcodes as a ZIP. Review invalid rows before delivery so the exported set matches your intended records. A downloaded barcode image still needs to be placed and printed at an appropriate size for your scanner and label stock.
Why do some rows fail barcode validation?
The selected format may not accept the value’s characters or digit count. Check the format requirements and correct source errors before trying again. Do not alter an otherwise valid business identifier simply to make it fit an unsuitable barcode format.
Is spreadsheet data uploaded to a server?
Standard spreadsheet parsing and barcode rendering happen in your browser. If you choose AI-assisted setup, relevant input such as your prompt and spreadsheet sample is sent for AI processing. You can use the manual, import and sequence tools without requesting an AI plan.
