EDI X12 vs UN/EDIFACT

The table below highlights the difference between the EDI X12 standard and EDIFACT standard. Topic ANSI X12 UN/EDIFACT Application - Mostly  used in U.S and North America - Mostly used in Europe and Asia Terminologies Equivalence  - Transaction Sets - Messages      - Loops     - Groups      - Terminators     - Separators Interchange Header/Trailer Segments  - ISA/IEA - UNB/UNZ Group Header/Trailer Segments  - GS/GE - UNG/UNE (optional) Transaction Set, (Message)  Header/Trailer Segments  - ST/SE - UNH/UNT Separators Specification Segment   - None -  UNA (optional) Commonly used Terminators, (Separators) Segment ~ ' Element * + Composite > : Release Indicator   - Not supported - Supported     Composite Elements      - Rarely used     - Commonly Used Acknowledgment   - TA1 and 997 - CONTRL Binary support  - BIN, BDS segments -  ISO 9735-8 - Associated data in EDI ? Security  - ASC X12.58 - Security Structures -  ISO 9735-5 - Security rules for batch EDI (authenticity, integrity and non-repudiation of origin) -  ISO 9735-6 - Secure authentication and acknowledgement message (message type - AUTACK) -  ISO 9735-7 - Security rules for batch EDI (confidentiality) -  ISO 9735-9 - Security key and certificate management message (message type - KEYMAN) The main difference between EDIFACT and X12 are 1.EDIFACT uses composite data elements 2.Looping and nesting procedures are different 3.There are 6 data elements types are defined in ANSI X12 while only three are defined in EDIFACT 4.There is no provision in EDIFACT for optional fields 5.EDIFACT allows for two levels of syntax 6.And ofcourse the message structure in both standards is different for different messages.
