Let us help you with Amazon’s compliance guidelines…

Amazon: A barcode is a symbol that allows an optical scanning tool to identify the product or book title.	Amazon requires that all non-book products carry a UPC barcode (Universal Product Code). We are the most visited and preferred site to safely buy official and legal UPC barcodes. You can order your UPC number(s) without the barcode graphic here Book products to be sold on Amazon should carry an ISBN barcode (International Standard Book Number).
Amazon: The barcode of product type must scan to an original ISBN or UPC number. If you get a new ISBN or UPC number, you must get a new ISBN or UPC barcode.	Amazon, in order to properly identify your products in their inventory management system, requires a different UPC barcode for each product. Example: You produce and sell picture frames and want to offer your frames for sale on Amazon. You carry two colors dark walnut and cherry, and both frames come in three sizes including small, medium and large. How many unique UPC codes are required? The answer: Six Why? Product One: Dark Walnut Frame Small Product Two: Dark Walnut Frame Medium Product Three: Dark Walnut Frame Large Product Four: Cherry Frame Small Product Five: Cherry Frame Medium Product Six: Cherry Frame Large
Amazon: To ensure proper scanning, bar codes should be tested with a full ANSI-certified verifier.	We use ANSI-certified Motorola Symbol equipment to test-scan all barcode label orders. Simply Barcodes strongly recommends test-scanning any UPC code prototype produced by your manufacturing facility before going into mass production.
Amazon: If you print your own UPC barcodes, be aware that defects may reduce scannability.	We are barcode experts. Most local print shops have no experience with the unique requirements of barcode printing and trying to do it yourself may not produce a scannable barcode.
Amazon: Bar codes should be printed with black ink on a white background, and there must be 1/4-inch of white space on the left and right sides of your bar code.	We know the requirements and our years of experience offer you peace of mind.
Amazon: If your bar code does not scan, you will be liable for non-compliance charges.	Avoid this costly problem! Our barcode labels conform to the recommended specifications of the barcode equipment manufacturers, and we test-scan to verify usability. We also offer test-scanning of barcodes and encourage you to use this service before going into mass production.
Amazon: New CDs and DVDs should always be shrink-wrapped differentiating them from used copies. Bar code must scan through any protective packaging.	Is your barcode’s scannability in question due to the thickness, quality or other reasons? We offer a variety of solutions including: 1. Label the outside of your product. 2. Order high-quality, retail-ready CD or DVDs
Amazon: The validity of a Product ID is checked against the GS1 GEPIR and ISBN.org databases. If your Product ID is not registered with GS1 then the linked ASIN will be suppressed and it may result in removal of your product creation privileges.	You will encounter this message when first listing a product on Amazon. All of our UPC Codes (Product IDs) originate from GS1 and are properly registered. You can check the “Don’t show this again” box and click “Got it.”
