Different Parties in X12 Name (N1) Segment

N1 (Name) segment is used to identify parties involved in a transaction.

Each party is designated by a qualifier in the N101 data element, which specifies the type of entity being referenced. 

N1 Segment Structure

The N1 segment typically includes the following data elements:

Element	Description
N101	Entity Identifier Code (e.g., BY, ST).
N102	Name of the party (e.g., company name).
N103	Identification Code Qualifier (e.g., 92).
N104	Identification Code (e.g., DUNS, GLN, etc.).

Example:

N1*BY*Acme Corporation*92*123456789~

N1*ST*Warehouse A*92*987654321~

X12 – Name Segment Key Considerations

• Mandatory or Optional: The use of specific N1 segments depends on the EDI transaction set (e.g., 850, 856, 810) and business requirements.
• Qualifiers Consistency: Ensure that the correct qualifier is used for each party to avoid processing errors.
• Multiple N1 Segments: A single transaction can include multiple N1 segments to identify different parties (e.g., Buyer, Seller, Ship To).
