Which is better Code 39 or 128?
Capacity. A Code 39 barcode encodes 39 characters in total. However, in its most recent version, the character set has been increased to 43. A Code 128 barcode is more powerful because it can encode a full 128 ASCII character set.
How do I read a Code 128 barcode?
Overall Structure. A Code 128 barcode begins with a START character, followed by the DATA characters, followed by the CHECK character, and finally a STOP character. The whole barcode symbol must also include a quiet zone of white space both before the START character and after the STOP character.
How long can a Code 128 barcode be?
48 characters
The standard definition of Code 128 does not limit the number of characters that can be encoded, however GS1-128 (the formal application of Code 128 to the supply chain industry) limits it to 48 characters.
How do you calculate 128 checksum?
Each character of the Code 128 character set has a numeric value. To calculate the checksum the values of all characters (including the start character) are multiplied by a weight factor, then summed up. The result is integer divided by 103, the remainder is the checksum (that’s a basic Modulo 103 operation).
What is a GS1-128 number?
The GS1-128 barcode (data carrier) was developed to provide a global standard for exchanging data between different companies. GS1-128 not only encodes the data, but it also provides a method of defining the meaning of the data by defining a list of “Application Identifiers” (AI’s).

Is Code 128 the same as GS1 128?
Code 128 Symbology
Code 128 is a very common and popular linear symbology. It has been adapted for use with the GS1 system and barcodes utilizing the GS1 format of Code 128 are known as either UCC/EAN-128 or now GS1-128.
Is GS1-128 same as Code 128?
GS1-128 is by itself not a bar code language (symbology). It is a standard that defines both the kind of data and the data format. In essence, GS1-128 is a derivative language of the Code 128 symbology, utilizing a flagging character (Function Code 1 (FNC1)) and application identifiers.
How much does GS1 cost?
The one-time cost for licensing a single GS1 US GTIN is $30, with no annual renewal fee. The initial cost of licensing a GS1 Company Prefix ranges from $250 to $10,500 which enables you to uniquely identify from 10 to 100,000 products, locations or assets.
