At present, there are only three kinds of internationally used and recognized logistics barcode codes: ITF-14 barcode, EAN-13 barcode, UCC/EAN-128 (also known as EAN/UCC128) barcode. When choosing logistics barcodes, it is necessary to choose different types of barcode codes according to the different goods and different commodity packaging.
For example, the packaging box of a single large product, such as a TV, refrigerator, washing machine and other goods, often uses the EAN-13 barcode type; ITF-14 barcodes or UCC/EAN-128 barcodes are often used in storage and transportation boxes, and the boxes can contain a single product, different products, or small packages of multi-head goods.
Next, let's briefly understand the basic information of these three logistics barcode symbolosystems.
1. ITF-14 barcode
The ITF-14 barcode is a cross-25 barcode that can encode 14-digit data with a fixed length (the last digit is the check digit, which can be generated by the barcode printing software). ITF-14 barcode can only be used in logistics warehousing, and the barcode printing accuracy is not high, and it can be directly printed on the outer packaging of logistics packaging boxes. ITF-14 barcode and ordinary barcode, the general ITF-14 barcode is surrounded by a rectangular frame, or only two supporting lines.
So which software can make ITF-14 barcodes? You can refer to the article: Which barcode printing software can make ITF-14 barcodes?
二、UCC/EAN-128条码（EAN/UCC128）
UCC/EAN-128 barcode is a continuous, non-fixed-length barcode, which can identify more information to be represented in the trade unit, such as product lot number, quantity, specification, production date, expiration date, delivery place, etc.
EAN/UCC128 barcode can represent variable-length data, the length of the barcode symbol varies according to the number of characters, type, and magnification factor, and can encode several information in a barcode symbol. The maximum number of data words that can be encoded by this symbol barcode is 48, and the physical length, including the blank space, cannot exceed 165mm.
三、EAN-13条码
The EAN-13 barcode is the most common type of barcode. EAN-13 is not only a product barcode, but also a barcode on the packaging of the goods.
