Code 128 is a high-density linear symbology that encodes text, numbers, numerous functions and the entire 128 ASCII character set (from ASCII 0 to ASCII 128.) It is commonly used for several implementations; and is also referred to as ISBT-128, GS1-128, UCC-128, EAN-128 and USS Code 128. Code 128 contains 106 different printed barcode patterns. Each printed barcode may have one of three different meanings depending upon which of the character sets are being used, with the availability of three different Code 128 start characters to program the initial character set. Functions are also provided in the barcode symbology to switch between character sets and encode Application Identifiers. Code 128 may be complex to use because of the different character sets, which is the primary reason IDAutomation provides the Code 128 auto function, "Code128( )", in several of their Font Tools, Components and Applications.The complete Code 128 barcode consists of a start character, data digits, a modulo 103 check digit and a stop character.Start Character Data Digits Check Character Stop Character

The above symbol was created with the IDAutomation Image Generator.Various Standards for the Code 128 Symbology
Several standards exist that dictate how Code 128 barcodes should be generated for certain implementations; a few of these include:GS1-128 (previously known as UCC-128 and EAN-128) is used to create several types of barcode symbols that include Application Identifiers. Application Identifiers (AIs) define the purpose of the data in the symbol and how it is to be used.
ISBT-128 is specifically designed for the purpose of printing blood product labels. It was developed by the International Society of Blood Transfusion (ISBT) and the Working Party on Automation and Data Processing (WPADP).
USS Code 128 (Uniform Symbology Specification Code 128) is the published specification for Code 128.
ISS Code 128 (International Symbology Specification Code 128) is the USS Code 128 symbology with a new feature that allows the encoding of extended ASCII characters for non-English languages.
The Global Trade Item Number (GTIN), or previously known as EAN14, is the product identification structure in the GS1 (EAN/UCC) system. The GTIN is a 14 digit fixed length numeric string, including the indicator digit (or logistic variant), the EAN/UCC company prefix, item reference and check digit. When using the EAN128 symbology, the data will need to be appended with the Fnc1 character and an Application Identifier of 01. The GTIN should always be stored in databases as a 14-digit number. When the GTIN is represented in UPC-A, UPC-E, GTIN-8 and GTIN-13, as 8, 12, or 13 digits, it should be stored as a 14-digit number by appending zeros to the beginning of the data.
Products for Printing Code 128
Several Barcode Integration Guides are available that suggest one or more barcode printing options. These integration options should be examined to determine whether to use barcode components, applications or fonts for the printing of barcodes. A few of the Barcode Integration Guides offered include the following:Access
Crystal Reports
Excel
FileMaker
Open Office & Star Office
Oracle Reports
Reporting Services
C++
C# .NET
Visual Basic 6 and VB.NET
Web Barcode Implementation
Featured Product:IDAutomation's Universal Barcode Font Advantage Package is a unique product that excels at generating Code-128 barcodes on multiple operating systems and locales, including Double Byte versions of Windows. This package overcomes the obstacles that sometimes occur when printing Code 128 as a barcode font outside of the Unites States.Reading & Scanning Code 128 Barcodes
The most common method of reading barcodes is with a barcode scanner. Most of the barcode scanners recommended by IDAutomation perform keyboard emulation and receive power from the USB port, so that no external power supply is required. When a barcode is scanned using keyboard emulation, the data scanned appears at the cursor as if it had been typed in from the keyboard.Most barcode scanners have the ability to read Code 128 barcodes by default, such as the IDAutomation SC5 USB CCD Scanner. This scanner dependably reads IDAutomation抯 Code 128 Font and Universal Barcode Font when printed as small as 6 points, which is an X dimension of 4 mils.
Creating GS1-128 (UCC/EAN 128) Compliant Barcodes Notice: GS1 recently renamed several barcode standards built on Code 128 such as EAN-128 and UCC-128 to GS1-128. The name change does not change the barcode standards, therefore documentation referring to EAN-128 and UCC-128 is the same as GS1-128. GS1 also recently renamed the RSS Symbology to GS1 DataBar to avoid confusion with RSS feed technology.The Code 128 symbology is used to create GS1-128 (formerly UCC128 or EAN128) barcodes such as the GS1-128 symbols and data structure for SSCC18 and SCC14. When using Code 128 to create GS1-128, every barcode must begin with a Start C character followed by a (FNC1) "function code one" and an Application Identifier (AI) number directly after each FNC1. Additional FNC1 codes may be applied to a barcode to encode additional information. Below are some of the requirements for GS1-128 and how to use them.Symbol Size:
According to GS1-128 specifications, the height of the bar code should be 15% of the length or 0.50 inch (1.3 CM), whichever is greater. The X dimension may range from 10 mils (.025 cm) to 40 mils (.1 cm). When the X dimension used is between 10 and 16 mils, the symbol should be 0.50" tall. When the X dimension used is between 16 and 40 mils, the symbol should be 1.25" tall. The X dimension of 10 mils (0.10") is recommended for use with most hand-held scanners. IDAutomation's Code 128 Font IDAutomationC128M and Universal Font IDAutomation Uni M are specifically designed for this purpose. They are exactly 0.50" tall with an X dimension of 10 mils when printed at 12 points.
GS1 FNC1 and the Application Identifier (AI):
The Application Identifier (AI) defines the barcode data fields in the GS1-128 barcode. Each AI uniquely identifies the meaning and format of the data following it. The AI has parentheses around it in the human readable form of the information. However, the parentheses are not encoded in the barcode.
In some situations, the parentheses may not appear in the text portion of the barcode. If the ASCII 202 character is included in the Code 128 Auto function and the parentheses are not around the correct number of digits for the AI or do not exist, the FNC1 is still encoded in the barcode and the barcode is accurate except for the human readable representation. To make the human-readable digits accurate as well, enter the following extended ASCII character as the FNC1 for the correct number of digits in the AI with the ApplyTilde property enabled:
~212 = 2 digits ~213 = 3 digits ~214 = 4 digits
~215 = 5 digits ~216 = 6 digits ~ 217 = 7 digits
For example, to encode 77(1234)0128, the data of 77~21412340128 would be used.
A few examples of encoding GS1-128 (UCC-128 or EAN-128) barcodes using IDAutomation products are included in Fig 1.
FNC2:
The FNC2 character may be inserted as ASCII 197 in IDAutomation's products, for example: ~19780-128-4991 encodes [FNC2]80-128-4991. IDAutomation抯 SC5USB Scanner may be programmed to hold the barcode starting with the FNC2 in memory and only transmit data after scanning a second barcode, which allows a continuous text string to be encoded in two barcodes.

A GS1 MOD 10 check digit is often required when implementing GS1-128 barcodes for various specifications; the AI is usually not included in the MOD 10 calculation. If a MOD 10 check digit is needed, it may be either pre-calculated or calculated in the barcode component at the time the barcode is created. To enable IDAutomation's products to calculate the MOD 10 when the barcode is created, the ApplyTilde property must be enabled and the format ~m?? must be used where ?? is a 2 digit number representing the number of characters preceding the tilde on which to base the Mod 10 calculation. For example, entering the data of ~2140000801234999999999~m17 creates a barcode encoding the FNC1 character followed by an AI of (00) and the number of 008012349999999997. This MOD 10 calculation may be checked online with IDAutomation's Online Barcode Font Encoder by entering the number of 00801234999999999 in the "Data To Encode" field and choosing the "MOD 10" option.
Fig. 1: Examples of Encoding GS1-128 (UCC/EAN-128) with IDAutomation ProductsIn all examples below, the ASCII 202 character ?/font> may be used in place of ~??? for any IDAutomation products that do not support ApplyTilde.
The ~m?? option is only used to calculate the MOD 10 check digit. If the check digit is pre-calculated and appended to the data by another process, this option should not be used.
Only the data in normal text color needs to be produced to create the desired result. For example, the SSCC-18 barcode may be produced in the Crystal Reports Native Barcode Generator by including a field named SSCC18 in the following formula:
DataToEncode = "~212" & {Table1_.SSCC18} & "~m17" according to the tutorial.

* Many bar code scanners do not decode FNC1 codes. However, when the "format" option of IDAutomation's SC5USB Scanner is set to "UCC/EAN-128", FNC1 codes are decoded as ]C1 for the first FNC1 and ASCII 29 (The [GS] character) for additional FNC1 codes as required by GS1.Decoding and Reading GS1-128 (UCC/EAN128) FNC codes
Most scanners with built-in decoders do not decode FNC1 codes in GS1-128 (UCC/EAN-128) barcodes. However, when the "format" option of IDAutomation抯 SC5USB Scanner is set to "UCC/EAN-128", the scanner decodes FNC1 codes according to the UCC/EAN Application Identifier Standard. According to this standard, the first FNC1 should be translated to the three text characters of ]C1, and next FNC1 codes should be translated to a field separator ASCII code 29 (The [GS] character) as demonstrated in Fig. 2.

Decoded result from the IDAutomation SC5 USB Scanner:
]C1 8100712345 [GS]* 2112345678 * The [GS] character is the group separator which is ASCII 29. This character cannot be viewed or printed and therefore it may not appear to be present. If the SC5 USB Barcode Scanner is being used, the GS character can be reassigned to any ASCII character by changing the "field separator code" referred to in the manual. This may be changed to the "|" character to make troubleshooting easier. After making that change, the scanner would decode the symbol in Fig. 2 as follows:
]C18100712345|2112345678.USPS EAN128 Barcodes
The United States Postal Service uses Code 128 barcodes for many special services such as delivery confirmation; which is formatted as follows:Start C character
FNC1 character
2 digit AI (Application Identifier, which is usually 91)
2 digit service code
9 digit customer ID
8 digit sequential package ID
Mod 10 check digit
Mod 103 symbology check digit
Stop character
The start, stop and mod 103 check digits are automatically added in all of IDAutomation barcode products. To create the required Code128 bar-code, use Code 128 Auto with ApplyTilde enabled and add in the appropriate ASCII 202 and AI抯 (as documented in the GS1-128 (EAN/UCC 128) information section of this FAQ). A MOD 10 Check Digit is also required at the end of the data encoded. This may be easily generated in IDAutomation's products with the ~m command as demonstrated in Fig 3.When printed at 16 points, the IDAutomationC128L font will produce the exact dimensions for GS1-128 (UCC/EAN Code128) required by the USPS special services, which is a height of .75" and an X dimension of .013". For more information, refer to the USPS specifications. More information about formatting GS1-128 barcodes with IDAutomation products is provided in the GS1-128 section of this FAQ.Fig. 3: Example of Encoding USPS BarcodesIn the example below, the ASCII 202 character (? may be used in place of ~??? for products that do not support ApplyTilde.USPS Compliant GS1-128 (UCC/EAN) for Special Services

The human-readable characters below the barcode may be easily generated with IDAutomation's products by utilizing the SpliceText option with the Sans Serif Bold or equivalent type font.In the event the human-readable characters below the barcode need to be created from code, the Sans Serif Bold font should be used and spaces should be inserted between every 4 digits. The following Visual Basic VBA code accomplishes this purpose:
Mid(DataToEncode, 1, 4) & " " & Mid(DataToEncode, 5, 4) & " " & Mid(DataToEncode, 9, 4) & " " & Mid(DataToEncode, 13, 4) & " " & Mid(DataToEncode, 17, 4) & " " & Mid(DataToEncode, 21, 2)Several other combinations are possible. For more information, refer to the USPS specifications. The USPS has also standardized on a newer 4-state barcode type defined as Intelligent Mail, which encodes delivery and tracking information in a single symbol.

]的C1 8100712345 [人] * 2112345678 * [人]性格是该集团分离器是ASCII码29 。这个字不能观看或打印，因此，它可能似乎没有出席。如果sc5的USB条码扫描器是被利用，成为GS性格可以重新分配给任何的ASCII字符，通过改变"场分离器代码" ，是指在手册中。这可能会改为" | "性格，使故障排除更加容易。经过这一变化，扫描器将解码符号图。二如下：
] c18100712345 | 2112345678 。 美国邮政ean128条形码
美国邮政服务使用代码128条码，为许多特殊服务，如发货确认哪一个是格式化如下： 开始c字符
fnc1性格
二位数字的爱（应用标识符，它通常是91 ）
第2位数字代码服务
第9位顾客身份证
第8位数字的顺序一揽子身份证
英国国防部10个校验数位
按付款当日价格计算103符号校验数位
停止性格
一开始，停止和国防部103核对数字自动添加在所有idautomation条码产品。创造所需code128条码，使用代码128自动applytilde启用并加上适当的ASCII 202和AI抯（如记录在加入GS1 - 128 （环境评估及噪音/条UCC 128 ） ，信息科的此FAQ ） 。一英国国防部10个校验数位，还需要在去年底的数据编码。这可能是很容易产生idautomation的产品与〜米指挥表现为图3 。 打印时16分， idautomationc128l字体将产生的确切尺寸的GS1 - 128 （条UCC / EAN统一code128 ）必须由美国邮政的特殊服务，这是一个身高0.75 "和一个X维的0.013 " 。欲了解更多信息，是指以USPS的规格。更多有关格式化的GS1 - 128条形码idautomation产品是在加入GS1 - 128条的这一常见问题。 图。 3 ：例如编码USPS的条形码在下面的例子中， ASCII的202个字符（ ？可用于代替〜 ？ ？ ？产品不支持applytilde 。 美国邮政兼容的GS1 - 128 （条UCC /噪音） ，为特殊服务
理想的结果是： [ fnc1 ]四二○一二三四五[ fnc1 ]九一○一一二三四五六七八九一二三四五六七八[ mod10 ]

数据扫描条码： * ] c1420123459101123456789123456789 * USPS的字下面条码
人类可读的字下面条码，可很容易产生与idautomation的产品，利用splicetext选择与无衬粗体或同等类型的字体。 在发生人类可读的字下面条码需要创造，从典，无衬线字体大胆应使用位应插间，每4位数字。以下Visual Basic中VBA的代码完成这一目的：
中期（ datatoencode ， 1 ， 4 ） ＆ " " ＆中旬（ datatoencode ， 5 ， 4 ） ＆ " " ＆中旬（ datatoencode ， 9 ， 4 ） ＆ " " ＆中旬（ datatoencode ， 13日， 4 ） ＆ " " ＆中旬（ datatoencode ， 17 ， 4 ） ＆ " " ＆中旬（ datatoencode ， 21日， 2 ） 其他几个组合都是可能的。欲了解更多信息，是指以USPS的规格。美国邮政局也规范对一个新的四国条码类型定义为智能邮件，编码交付和跟踪信息，在一个单一的象征。
asp.net论坛居然出现这种东西，难怪别人搜索帖子都找不到正确结果
