EDI Purchase Order Number (Reference Number for Union Pacific)
EDI Purchase Order Number is the key reference number for Union Pacific. It ties together all EDI communications about a purchase, including payment. It is the Supply Department’s responsibility to furnish the supplier with a purchase order number for EDI all purchases. It is the Supplier’s responsibility to use that number in all EDI communications with Union Pacific.
Consequently, Union Pacific requests that the purchase order number be clearly shown on all:
- Order acknowledgments
- Shipping notices
- Delivery documents
- Packing lists
- Credit memos
- Any other purchase order-related documents
The number on a Union Pacific purchase order has been designed specifically to provide information about the order. There are several different types of supply purchase orders, each with its own particular number configuration, depending on the item(s) being ordered.
