Supplier Frequently Asked Questions

Please complete the supplier registration form found on the website.


Review the buyer list and contact the appropriate buyer and schedule a meeting or introduction regarding your company offerings.


Please be aware that registration does not automatically place your company on Union Pacific's Bid list. Registration allows the buyer to view all companies potentially capable of providing the related goods or services. Some products or services may require approval and/or testing by Union Pacific.

Please view our Suppliers Code of Conduct.

Bids are closed, and are issued by invitation only. Timing of bid releases may vary.

You should contact the appropriate category manager with questions concerning upcoming bids. However, please be aware that this does not mean your company will be included in the bid process.

Union Pacific uses an invitation-only closed bid process, except as may be required with government programs. Therefore, invitations are determined based on:

  • the product and/or services being bid;
  • the strategy as developed by the category manager; and/or
  • the suppliers capabilities as understood.


It is the responsibility of the Supplier to ensure that Union Pacific is fully aware of Supplier capabilities through the supplier registration process. However, this does not guarantee inclusion in the bid process.

As a courtesy, Union Pacific will its make best efforts to notify suppliers regarding bid status, but it is not required do so. The successful bidder will be notified. Reasons for not being awarded are based on the bid criteria. Union Pacific uses a Total Cost of Ownership process which does not warrant that the lowest price supplier always will be awarded the business.
