Global product coding and barcode services. Bangma International specializes in one-stop application and registration of domestic and international product barcodes — from China 69 codes to international EAN and UPC, ensuring products are correctly identified in every market.
From factory outbound, to supermarket checkout, to listing on cross-border platforms, the product must be machine-read at every step. The barcode is its sole identity credential along the way — printed on the packaging, written into the system.

GTIN is the numbering system, EAN is the international universal code, and UPC is the North American retail code — they are not three separate things, but the expression of the same global system in different markets.
In the GS1 system, product numbers are 8 / 12 / 13 / 14 digits long and are the overarching concept for all product codes. The same product can be expressed with GTINs of different lengths at different stages.
EAN-13 is the standard for retail checkout in Europe and most markets, with the widest global applicability. Prefixes such as 69 for China, 489 for Hong Kong, China, and 50 for the UK all fall within the EAN-13 system.
UPC-A is 12 digits and is commonly used for retail checkout in the United States and Canada, and is commonly required for listing on North American platforms such as Amazon. Technically it is equivalent to an EAN-13 with a leading 0.
Each GS1 prefix represents an assigned region. We render barcodes for common markets in their own dedicated colors — so you can see at a glance which market a product is headed to and which "ID card" it needs. Click any barcode to view the services and keywords carried on that page.

All tools are housed in the "Barcode Tools" section, with no scattered entries elsewhere. Let's start with the most commonly used one — barcode format validation.
Digit count and check digit validation for EAN-13 / UPC-A / ITF-14
Tool 02Real-time barcode graphic rendering according to international standards
Tool 03Validate an entire batch of barcodes at once, with results given line by line
Tool 04Enter a 3-digit prefix to look up the region to which the number range belongs
Tool 05GTIN-8 / 12 / 13 / 14 length expansion and compression
Tool 06Estimate the number of codes needed based on the number of brands and SKUs
Enter a 13-digit EAN-13 or 12-digit UPC-A to immediately check whether the check digit is correct.
Note: This ismathematical format validation, which can only determine whether the number composition is legal,and cannot be used to determine whether a product is genuine, nor can it determine whether the code has already been registered.
Different industries face different problems: e-commerce needs to consider platform rules, exports need to choose the correct number range, and supermarkets need to pass quality inspection. Choose your scenario to see the solution directly.
