What Is a Barcode Generator?

A barcode generator is a tool that turns numbers, product codes, SKUs or text into a scannable barcode. Businesses use barcodes to label products, cartons, shelves, inventory locations, delivery documents and order forms.

For wholesalers, distributors and retailers, barcodes help make daily operations faster and more accurate. Instead of typing product codes manually, your team can scan a barcode to identify the correct product, carton or order.

A barcode generator is useful when you need to create product labels, warehouse labels, carton labels or internal tracking codes quickly.

Common Barcode Types for Business

Different barcode types are used for different business purposes. Choosing the right barcode type depends on whether you are creating labels for internal use, retail products, cartons or QR-based information.

• Code 128

Code 128 is one of the most flexible barcode types for business use. It can support numbers, letters and special characters, making it suitable for SKU codes, product labels, warehouse labels and internal inventory tracking.

Many businesses use Code 128 for internal product codes because it is easy to generate and works well for stock control.

• EAN-13

EAN-13 is commonly used for retail products. It is a 13-digit barcode format often seen on product packaging in supermarkets, retail stores and distribution channels.

If you are selling products through retail stores, marketplaces or large distributors, you may need a valid EAN-13 barcode assigned to your product.

• UPC-A

UPC-A is another common retail barcode format, especially for products sold in markets that use UPC barcodes. It is often used on retail packaging and product labels.

• ITF-14

ITF-14 is commonly used for cartons, outer cases and logistics packaging. It is useful when businesses need to label carton-level packaging instead of individual product units.

Wholesalers and distributors may use ITF-14 for carton tracking, warehouse receiving and bulk shipment identification.

• QR Code

A QR code can store more information than a normal barcode. It can be used for website links, product pages, warranty forms, digital catalogs, order information or customer service links.

QR codes are useful when you want customers, sales teams or warehouse staff to access extra information by scanning the code with a phone.

How to Generate a Barcode

To generate a barcode, enter your barcode data, choose the barcode type and customize the size. After the barcode is generated, you can download it and use it on labels, packaging, documents or internal systems.

For internal product labels, Code 128 is usually a good option because it supports letters and numbers.

For retail product packaging, EAN-13 or UPC-A may be more suitable, depending on your market and product requirements.

For carton labels and outer case labels, ITF-14 is commonly used.

For links, product pages or digital information, QR code is usually the better choice.

Before printing barcodes for retail use, make sure the barcode number is valid and assigned correctly to your product or business.

Barcode Generator for Wholesalers and Distributors

Wholesalers and distributors often manage many products, customers and orders at the same time. A barcode generator can help create simple product labels and carton labels so the team can identify items more quickly.

This is especially useful when a business has many SKUs, similar product names, different carton sizes or repeat B2B orders from multiple customers.

Barcodes can support daily workflows such as stock receiving, order picking, packing, stock take and delivery preparation.

When product codes are clear and scannable, your team can reduce manual errors and work faster.

Barcode Generator for Inventory and Warehouse Teams

Inventory and warehouse teams can use barcodes to improve product identification and stock movement.

For example, a warehouse can place barcodes on products, cartons, bins or shelf locations. When stock is received, moved, picked or counted, the team can scan the barcode instead of manually typing the product code.

This helps reduce mistakes, especially when products have long SKU numbers, similar names or multiple variations.

A barcode generator is a simple starting point for creating barcode labels. For full inventory control, businesses usually combine barcode labels with an order management, inventory or warehouse system.

Barcode Generator for Product Labels

Product labels usually need clear and scannable barcodes so the product can be identified quickly. This is useful for retail sales, inventory tracking, picking, packing and stock take.

When creating barcode labels, make sure the barcode is large enough to scan clearly. The printed label should not be too small, blurry or stretched.

For internal product labels, you can use your own SKU or product code. For retail product labels, make sure the barcode number follows the required format and is valid for your product.

Barcode Generator for Carton Labels

Carton labels are useful for businesses that sell, store or ship products in bulk. Instead of scanning individual products, your team can scan the carton barcode to identify the carton or shipment.

This is helpful for wholesalers, distributors, importers and warehouse teams that handle many cartons every day.

Carton barcodes can be used for receiving goods, checking stock, preparing deliveries and tracking bulk orders.

PNG vs SVG Barcode Download

PNG and SVG are both useful barcode download formats, but they are used for different purposes.

PNG is suitable for quick printing, documents, product sheets and basic label usage. It is easy to open and use in most design or office tools.

SVG is better when you need high-quality printing or resizing. Because SVG is a vector format, it can be resized without losing quality. This makes it useful for packaging design, label design and professional printing.

If you are not sure which format to use, PNG is usually fine for simple labels. SVG is better for design or printing work that needs sharper quality.

From Barcode Labels to Faster B2B Ordering

A barcode generator helps you create product and carton labels. But after the labels are created, your team still needs to manage orders, stock availability, customer pricing and accounting updates.

SalesHero helps wholesalers and distributors move beyond manual order taking. Your sales team can create orders from mobile, check product information, view stock availability and sync orders to accounting.

This helps your team reduce manual work, avoid repeated data entry and process B2B orders faster.
