This transaction would contain information such as the employee’s name, address, Social Security Number, and the benefits being enrolled in, along with coverage’s start and end dates.

Standardized EDI Transaction Codes

EDI transaction codes are one of the most significant elements of EDI transactions. The data being exchanged is organized and formatted using these codes, called EDI standards.

EDI transaction codes list come in various forms, including ANSI X12, EDIFACT, TRADACOMS, and others. These code sets each has their own distinct syntax and structure and are created and maintained by various standard groups.

EDI (Electronic Data Interchange) transaction codes are standardized codes employed to specify the type of EDI document transmitted between trading partners. These codes, also known as “transaction sets,” select the EDI document’s intended use, such as a purchase order, invoice, or shipping notice.

ANSI X12 EDI transactions, widely used in the United States, is one of the most commonly employed EDI code standards. The first two digits of an ANSI X12 code determine the functional group, and the last two identify the transaction set. For example, Purchase Orders utilize the code “850,” while Invoices use the code “810”.

Another commonly used EDI code standard is UN/EDIFACT, used primarily in Europe and other international trading partners. UN/EDIFACT codes are composed of three letters, with the first letter indicating the functional group and the last two showing the transaction set. For example, the code “ORDERS” is used for purchase orders, while “INVOIC” is used for invoices.

The majority of TRADACOMS codes are used in the United Kingdom. Five digits make up TRADACOMS codes, the last three representing the transaction set, while the first two representing the functional group. Invoices, for instance, use the code “810,” while purchase orders use the code “650.”

It’s important to note that these codes and standards may vary depending on the industry and region. It’s crucial for trading partners to agree on the codes and standards to use for their EDI transactions for the data to be correctly translated and processed.


The American National Standards Institute for Electronic Data Interchange (ANSI X12) is the primary adopter of the EDI standard referred to as ANSI X12. The maintenance of the system is overseen by the Accredited Standards Committee (ASC) X12, an organization responsible for developing EDI standards. It was established by the Data Interchange Standards Association (DISA) to maintain and manage EDI standards.

The ANSI X12 standard comprises a number of transaction sets that are each given a four-digit code for identification. Each transaction set includes data elements used to communicate a specific collection of information, like the specifics of a purchase order or the total of an invoice. The first two digits of the transaction set code assist in identifying the functional groups into which the transaction sets and data elements are divided.

The standard design is hierarchical, with data segments being grouped into loops, which are subsequently grouped into functional groups. Data elements make up each segment and are divided by a delimiter. Carets are frequently used as delimiters in ANSI X12, though other delimiters like commas and pipes are also acceptable.

An example of an ANSI X12 transaction set is the Purchase Order (850). This set of transactions is utilized to convey purchase order details between a purchaser and a vendor. The 850 transaction set contains functional groups such as the “header” group, which contains information about the sender and receiver, and the “detail” group, which contains information about the ordered items. Within the detail, groups are loops for line item details and segments for product ID, quantity, and unit price.


This is a standard for electronic data interchange (EDI) used primarily in Europe and other international trading partners. It is a system established and continuously updated by the United Nations Economic Commission for Europe (UNECE).

The UN/EDIFACT standard comprises a series of message types identified by a three-letter code. Each message type comprises data elements employed to transmit specific information, such as purchase order information or invoice totals. Functional groups are formed by grouping the message types and data elements according to the first letter of the message type code.

The standard structure is hierarchical, with data segments being grouped into loops, which are subsequently grouped into functional groups. Data elements make up each segment and are divided by a delimiter. The plus (+) sign is typically used as a delimiter in UN/EDIFACT, but other delimiters, including commas and pipes, are also acceptable.

An example of a UN/EDIFACT message type is the Order message (ORDERS). This message type conveys purchase order information between a buyer and a seller. The ORDER message type contains functional groups such as the “header” group, which contains information about the sender and receiver, and the “detail” group, which contains information about the ordered items. Within the detail, groups are loops for line item details and segments for product ID, quantity, and unit price.

TRADACOMS (Trading Communications System)

Electronic data interchange (EDI) standard TRADACOMS (Trading Communications System) is primarily used in the UK. It was created by the UK grocery sector, and GS1 UK is now responsible for maintaining it.

There are various message types included in the TRADACOMS standard, each of which is designated by a five-digit code. Each message type includes data elements that are used to communicate certain information, such as the specifics of a purchase order or the total of an invoice. The first two digits of the message type code are used to identify the functional groups into which the message types and data elements are divided.

Additionally, the TRADACOMS standard has a particular syntax and structure that must be adhered to. The standard design is hierarchical, with data segments being grouped into loops, which are subsequently grouped into functional groups. Data elements make up each segment and are divided by a delimiter. The comma (,) and the space are commonly used as the delimiter in TRADACOMS ( ).

An example of a TRADACOMS type is the Order message (650). This message type conveys purchase order information between a buyer and a seller. The 650 message type contains functional groups such as the “header” group, which contains information about the sender and receiver, and the “detail” group, which contains information about the ordered items. Within the detail, groups are loops for line item details and segments for product ID, quantity, and unit price.

Comparison of codes and their use in different industries

Regarding EDI, other sectors may have specific needs that dictate the use of certain codes and standards. For example, the healthcare industry may use ANSI X12 codes to comply with regulations such as HIPAA for their healthcare EDI transactions, while the automotive sector may use UN/EDIFACT codes to comply with global regulations.

For example, the retail industry commonly uses ANSI X12 codes for EDI transactions such as purchase orders (850), invoices (810), and advance ship notices (856). The retail sector frequently employs ANSI X12 codes for EDI transactions such as purchase orders, invoices, and shipping notifications. Additionally, it utilizes EDI to communicate with its vendors and other business associates.

To communicate with its suppliers and business partners, the automotive industry, on the other hand, frequently uses UN/EDIFACT codes for EDI transactions like purchase orders (ORDERS) and invoices (INVOIC). The grocery retail industry commonly uses TRADACOMS codes for EDI transactions such as purchase orders (650) and invoices (810). The grocery retail industry also uses EDI to communicate with its suppliers and trading partners.

For their EDI transactions to be effective and accurate, businesses must understand the codes and standards in their particular industry and work closely with their trading partners. Additionally, it’s critical for companies to keep abreast of any updates to the codes and standards prevalent in their sector.


The structure and format of electronic business documents like purchase orders and invoices are governed by a set of guidelines and regulations known as EDI standards when exchanged between trading partners. These standards ensure that the documents are traded in a consistent and uniform manner. These standards provide that electronic documents can be accurately translated and processed by the sender and receiver computer systems.

Several common EDI standards are frequently utilized for electronic business document exchange, including ANSI X12, UN/EDIFACT, and TRADACOMS.

These standards define the syntax, structure, and codes used for EDI transactions, including the format and content of electronic documents, the data elements that must be included, and the delimiters used to separate data elements. They also define the process for validating and testing EDI transactions to ensure they are accurate and complete.
