What is a bulk barcode generator?

A bulk barcode generator creates many barcodes from one input list. Instead of making a barcode for each value separately, you import or paste a list and get a matching barcode image for every row.

How do I create barcodes in bulk from an Excel file?

Click Import Excel and select your file (.xlsx or .xls), and each row becomes one barcode. If you prefer, copy your values in Excel or Google Sheets and paste them into the input box. Remove empty rows first so you do not get blank entries.

Can I paste two columns from Excel — value and display text?

Yes. Copy two columns and paste them into the input box: the Tab between them separates the two, the first column is encoded into the barcode, and the second is shown as the text under it. So a barcode holding the value 1234567890 can display 1234 567 890 underneath. If you do not want extra text, paste a single column.

Can I import a CSV file?

Yes. Click Import CSV, choose your file, and each row is turned into a barcode. This works well for exports from inventory, e-commerce, or accounting systems. Make sure the column you want to encode contains only the values you need.

Can I generate a sequence of numbers automatically?

Yes. Open Create sequence and set a prefix and suffix if you need one, the start value, the step between values, and the minimum number of digits. You can generate by quantity, or by end value and let the tool calculate how many barcodes that takes. The preview shows the first and last value before you add the sequence to the input box.

Can I download all barcodes as a ZIP file?

Yes. A single barcode downloads directly as an image. When you generate more than one, they are packed into one ZIP file in the format you selected (PNG, SVG, or JPG), with each file named after the barcode format and its position in the list, such as barcode-Code128_1.png.

Is my data uploaded to a server?

For the web tool, no. Barcodes are generated entirely in your browser and imported files are read locally, so your SKU lists, inventory IDs, and serial numbers are never uploaded. This makes it suitable for internal or sensitive lists. The image API works differently: it generates the barcode on the server, so the value you send appears in the request URL. The API is designed for automation and large volumes — use the browser tool when the data should stay on your machine.

Which barcode format is best for bulk labels?

For internal use such as inventory, asset tags, and serial numbers, Code 128 is the usual choice. For retail products use EAN-13 or UPC-A. For cartons use ITF-14, and for small labels or longer data use QR Code or Data Matrix.

How do I print the barcodes on labels?

Switch to the print layout, choose a grid such as 3 × 4, and the barcodes are arranged as labels on A4 pages that print straight from the browser. For sheets that must line up with Avery label stock, use our barcode label print tool, which prints a full sheet of labels at the correct physical size. For fully custom label designs, download SVG or PNG files and place them in your label software. Either way, print at 100% scale with fit-to-page scaling turned off and keep the white margin around each barcode.

Why did one of my lines not generate a barcode?

Each line must be valid for the format you chose. Common causes are letters in a numeric-only format such as EAN-13 or UPC-A, the wrong number of digits, an odd number of digits in Code 128C, or lowercase and special characters in Code 39. Switch to a format that accepts your data, or correct the line.

How many barcodes can I generate at once?

The web tool handles very large lists — imports of up to 3,000,000 rows are accepted. If you are generating tens of thousands of barcodes, SVG downloads are much faster than PNG because SVG is vector data. For unattended generation from your own software, scheduled jobs, or server-side workflows, use the API or CLI instead of the browser.

Is the bulk barcode generator free?

Yes. You can generate barcodes for free without creating an account. If you need to generate barcodes automatically from your own software or in very large volumes, use the API and CLI, which are designed for that.

Are these barcodes valid for retail or Amazon?

The generator encodes exactly the number you enter. For products sold in stores or on marketplaces, the EAN or UPC number itself must be a valid, unique number issued through GS1. A correctly drawn barcode does not make an unregistered number valid.

How can I check that my barcodes scan correctly?

Print one label and scan it with a phone or scanner before printing the whole batch. You can also upload an image of the barcode to our free online barcode scanner to confirm that it decodes to the value you expect.

Free Bulk Barcode Generator from Excel, CSV, or a List

Import an Excel or CSV file, paste a list (one column, or two columns copied straight from Excel), or generate a number sequence, and get a barcode for every row in real time. Choose Code 128, EAN-13, UPC-A, QR Code, Data Matrix and 30+ other formats, then download PNG, SVG, or JPG files, save the whole batch as a ZIP, or print labels. Free, no signup, and processed entirely in your browser.

Generate Barcodes in Bulk from Any List

A bulk barcode generator turns a list of values into many barcode images in one go. If you already have SKUs, inventory IDs, serial numbers, or product codes in a spreadsheet, import the file and every row becomes its own barcode, with no need to create them one at a time. Code 128 is a good default for inventory and internal labels, and you can switch to any other supported format at any time.

Import Excel or CSV, or Paste Two Columns
Upload an Excel spreadsheet or a CSV file and every row becomes a barcode. You can also paste straight from Excel or Google Sheets: copy one column for values only, or copy two columns and the Tab between them is used automatically, with the second column shown as the text under the barcode. Or type values one per line.
Create a Number Sequence Automatically
No list yet? Generate a numbered sequence, such as ABC-1001, ABC-1002, ABC-1003, and so on, and get a barcode for each number. It is a quick way to label bins, shelves, tickets, or a run of serial numbers.
Download a Whole Batch as a ZIP
Export a single barcode as an image, or save a full batch in one ZIP file instead of downloading files one by one. Choose PNG, SVG, or JPG depending on how you will use them.
Print Labels with a Print Layout
Switch to the print layout to arrange your barcodes as labels, then print them straight from the page. It saves a round trip through Word or a label design tool for simple label jobs.
30+ Formats, Processed in Your Browser
Switch between Code 128 (A, B, C), GS1-128, EAN-13, EAN-8, UPC-A, ITF-14, Code 39, GS1 DataBar, ISBN, QR Code, Data Matrix, PDF417, Aztec, and more. Everything is generated locally in your browser, so your list of SKUs or serial numbers is never uploaded.

How to Generate Barcodes in Bulk — Step by Step

Making a batch of barcodes takes a few minutes. Here is the workflow from spreadsheet to printed labels:

Choose a Barcode Format

Pick the format that matches how the labels will be used. Code 128 suits inventory, SKUs, serial numbers, and shipping. EAN-13 and UPC-A are for retail products and need valid numbers. QR Code and Data Matrix fit small labels or longer data. ITF-14 is common on shipping cartons.

Add Your Data

Import an Excel or CSV file, paste one or two columns from a spreadsheet, type values one per line, or create a number sequence. When you paste two columns, the first is encoded and the second is shown as the text under the barcode. Every line or row creates one barcode, so remove blank rows and make sure each value is valid for the format you chose.

Review and Adjust the Barcodes

Scroll through the preview and check that every barcode was created. Then adjust size, colors, and margins to fit your label. If a line does not generate, check that it follows the rules of the chosen format.

Download or Print

Download barcodes as PNG, SVG, or JPG, or save the whole batch as a ZIP. Use SVG when print quality matters. To print directly, switch to the print layout. Print at 100% scale without fit-to-page shrinking, then scan one printed label with our free online barcode scanner before printing the whole batch.

Which Barcode Format Should You Use for a Batch?

The right format depends on where the barcodes will be scanned. These are the most common choices for bulk label jobs.

Code 128 — Inventory, SKUs, and Serial Numbers

Code 128 encodes the full ASCII character set in a compact width, which makes it the usual choice for internal labels, asset IDs, and shipping. It is the best default for a bulk job when you control the numbering.

EAN-13 and UPC-A — Retail Products

Retail packaging uses EAN-13 (13 digits) or UPC-A (12 digits). These formats only accept digits, so a line containing letters will not generate.

ITF-14 and GS1-128 — Cartons and Logistics

ITF-14 is printed on outer cartons and GS1-128 carries structured shipping data such as batch numbers and expiry dates. Both are common in warehouse and supply chain workflows.

QR Code and Data Matrix — Small Labels and Longer Data

2D codes fit more data into less space and can be read from any angle. Data Matrix is popular for small parts and equipment, and QR Code for links and general use.
