ShipBots automatically generates a random barcode for you if you dont have one!
Barcoding may seem complicated and difficult - but its just a scannable piece of text or numbers (can even be your SKU in scannable format).
Almost anything scannable will work and our system can easily generate a barcode for you (if your shopping cart doesnt already have an associated barcode. )
Every product page has the following:

I. Introduction

You are undoubtedly familiar with barcodes, and you likely interact with barcoded products regularly.  Do you know what a barcode is, why it is essential, and how to add it to your products? We’ll cover all of this in detail below.

II. What is a Barcode?

By definition, a barcode is a method of representing data in a visual, machine-readable form. Traditionally, barcodes represented data by varying the widths and spacings of parallel lines. More recently, some variants utilize rectangles, dots, hexagons, and other patterns.
Simply put, a barcode is a visual representation of a series of letters, numbers, and symbols that a barcode reader can scan to identify the information presented. Some examples of different barcodes are below:
At ShipBots, we support a wide variety of 1D and 2D barcodes, including UPC/EAN versions UPC-A, UPC-E, EAN-8, EAN-13, Code 128-A, Code 128-B, Code 128-C, GS1-128, Code 39, ASIN, and FNSKU.

III. Why are Barcodes Important?

The most common application of barcodes is labeling products for identification and tracking purposes. At ShipBots, we use product barcodes throughout our processes to verify products in our warehouse and prevent human error. Some examples of this include:
  • Receiving- During receiving, barcoded products are scanned for verification against your ASN to ensure that the correct products are being received.
  • Returns- If the product is barcoded, we use it to identify the product returned to us by scanning its barcode during Returns Processing.
  • Movement of Inventory- Every time a barcoded product is moved within the warehouse, the barcode must be scanned to ensure the correct product is being moved.
  • Picking- When picking a product for an order, the picker must scan all barcoded products before proceeding to the next step.
  • Packing- For orders that fail our automated quality control process, the barcodes of the order’s contents must be scanned at the packing station.

IV. ShipBots’s Barcode Requirements & Recommendations

Requirements
  • Each barcode must be unique for each SKU.
  • All units of the same SKU must have the same barcode; if you have a product with a barcode that changes, the newly barcoded units must be a different SKU. Similarly, SKUs cannot have both non-barcoded and barcoded units in inventory; they must be stored under a separate SKU.
  • If you plan to sell Mastercases, Inner Cartons, and Eaches separately, they will each need their own unique barcode.
  • The barcode must be readable.
  • Do not print barcodes too small; this can make them difficult to scan. We recommend a minimum of 1.4" Wide by 1" Long.
  • Include some whitespace around the barcode on the label. We recommend at least 1/8 inch of blank space on each side of the barcode.
  • Do not print barcodes on a glossy or reflective material, as this can prevent the barcode scanner from being able to scan the barcodes.
  • Quiet Zones: This is the blank area around a barcode or a QR code.
    • Barcodes: 10 times the width of the narrowest bar (aka the "X" dimension) in a barcode or 1/8 inch, whichever is greater.
    • QR Codes: The quiet zone is recommended to be a minimum of 4 times the width of a single data square in the QR code image.
  • Barcode colors have to be contrasted for the laser to pick them up. Here are the barcodes that are contrast colors on a light-reflecting spectrum and will work on:

Recommendations
  • Keep the barcodes for inner cartons and eaches to 12 characters or less.
  • Avoid using an overly short or simple barcode that is likely to be repeated (001, 002, or 003, for example).
  • If creating your own barcodes, use the product’s SKU Name and the Product ID from your eCommerce platform.
  • Have your supplier apply barcodes before being shipped to us.

V. So I need barcodes….Now, what do I do?

ShipBots generates a random barcode for you if you dont have one!
If you decide that you don’t want to invest in your own set of barcodes today, that's not a problem; at ShipBots, we do not require that your barcodes be registered. You can create your barcodes by coming up with a series of letters, numbers, and symbols; unique for each of your products. You can take this unique code and utilize an online barcode generator to create barcodes. An example of a barcode generator is available here. We recommend using the UPC-A format. A couple of options to consider when coming up with your barcodes are your product’s SKU Name and the Product ID from your eCommerce platform.

VI. Barcode Locations

The best place for a barcode is on the packaging of the product. In a general sense, you would place the barcode in the lower right-hand section of the back of the package; we highly recommend avoiding any edge of the product and allowing some blank space around the barcode to help ensure a clean scan. Recommendation for Barcode Placement
  • The barcode should ideally be at least .25 inches and at most 4 inches from any of the edges of the product packaging.
  • The barcode should be located on the lower half of the back of the product packaging, preferably on the right-hand side.
  • Avoid placing the product on the bottom of the packaging.
  • Cylinders should have the barcode going up and down along the curve, otherwise the curve may make the barcode unreadable.

VII. Suggestions for Products that Don’t Come in Boxes

Whatever your brand, you may have some products for which how to barcode the product is complicated. We’ve listed some options below of packaging or barcode label types that you can add to your product to make barcoding a reality.
  • Poly Bags The addition of a polybag as packaging around your products makes barcoding incredibly easy. It also provides additional protection for the goods during transit and storage.
  • Belly Bands - A Belly Band can provide you with additional marketing space for your product as well as a location to add your barcode.
  • Jewelry Barcode Labels - Designed to wrap around a variety of jewelry without damaging the jewelry but still allow the barcodes to be effective.
  • Hang Tags - Print important information or utilize it for additional marketing while adding your barcodes using hang tags.
