How much does it cost to create a barcode?

Two parts: the number and the image. If you need an official UPC for retail, GS1 charges $250 initial + $50/year for up to 10 numbers. Generating the barcode image from your number is free using any online generator. For internal tracking only, both the number and the image are free — no registration.

Can I create a barcode for free?

Yes. For internal inventory tracking (warehouse, library, asset management), you can create both the number and the barcode image for free using Code 128 format. For retail products, you can generate the barcode image free, but you need to purchase the UPC number from GS1.

How do I add a barcode to my product label?

Generate the barcode, download as PNG, then add it to your label design in any tool — Canva, Adobe Illustrator, Word, Google Docs. Position the barcode where it will be scannable: flat surface, not wrapped around a curve, with white space on both sides.

What size should my barcode be?

Standard UPC-A barcode is 1.469" x 1.02" at 100% magnification. You can reduce to 80% minimum (1.175" x 0.816") for small packages. Below 80%, scanners may have trouble reading it. Always test with a scanner before printing your full label run.

Do I need a different barcode for each product variation?

Yes. Each unique product variation (different size, color, flavor, scent) needs its own UPC number. A medium blue shirt and a large blue shirt are different UPCs. This is why GS1 offers bulk pricing — 10 numbers for $250, 100 for $750, 1,000 for $2,500.

Can I create a barcode from my phone?

Yes. Browser-based barcode generators work in mobile browsers (Safari, Chrome). Enter your data, generate the barcode, download the PNG. Useful for creating quick labels on the go, though for print quality you may want to generate on a desktop.

How long does it take to get a barcode?

Generating the barcode image takes seconds. If you need official UPC numbers from GS1, their online registration is usually processed within 1-2 business days. The bottleneck is deciding which format you need and obtaining your numbers, not generating the image.

What is a check digit and do I need to calculate it?

The check digit is the last digit of a UPC or EAN number, calculated from the other digits using a specific formula. It prevents scanning errors. The barcode generator calculates this automatically — enter your base digits and the tool adds the correct check digit.

How to Create a Barcode for Your Products — Step by Step Guide

Last updated: April 20267 min readGenerator Tools

Creating a barcode for your product has two steps that most guides confuse: getting the number and generating the image. The number is the identity. The barcode is just a visual encoding of that number. Here is exactly how to do both.

Step 1: Decide — Official UPC or Internal Tracking?

Selling Where?	Need Official UPC?	Registration Required?	Cost
Amazon, Walmart, Target, grocery stores	Yes — UPC-A	GS1 registration	$250 initial + $50/year (10 numbers)
Shopify POS (in-store scanning)	Recommended — UPC-A	GS1 registration	$250 initial + $50/year
Shopify online only	Optional (needed for Google Shopping)	GS1 if you want it	$0-250
Etsy	Not required	None	$0
Your own retail store only	Your choice	GS1 or internal system	$0-250
Warehouse / inventory tracking	No — use Code 128	None	$0
Library / asset management	No — use Code 39 or Codabar	None	$0
Farmers market / craft fair	Not needed	None	$0

Step 2: Get Your Number (If Retail)

If you need an official UPC number:

Go to gs1.org and register as a company
Choose your capacity: 10 numbers ($250), 100 ($750), or 1,000 ($2,500)
GS1 assigns your company prefix — a unique set of starting digits
You assign the remaining digits to each product variation
The check digit (last digit) is calculated automatically

For internal tracking, skip this entirely. Create your own numbering system — "WH-001", "PROD-2026-A", whatever makes sense for your operation.

Step 3: Generate the Barcode Image

Open Barcode Generator
Select your format:
- UPC-A for US retail (12 digits)
- EAN-13 for international retail (13 digits)
- Code 128 for shipping, logistics, internal tracking
- Code 39 for warehouse, government, military
Enter your number
Download the barcode as PNG

Step 4: Add to Your Product Label

The barcode is now a PNG image. Add it to your label using any design tool:

Canva: Upload the PNG, drag onto your label template
Adobe Illustrator: Place the PNG in your packaging design
Word/Google Docs: Insert image into your label template
Avery labels: Import the PNG into Avery's label template tool

Need to adjust the barcode size first? Use our Image Resizer. Need to compress the image for web use? We have that too.
