“Bidder number assignment” refers to the software-supported process of systematically allocating unique identification numbers (bidder numbers) to participating companies or individuals within the framework of tenders, procurement procedures, or auctions. These numbers serve to manage bids in an anonymized and traceable manner and to structure communication and documentation throughout the procurement process.
The bidder number acts as an internal identifier in many electronic procurement systems, ensuring anonymity during the bidding phase. This supports transparency, fairness, and data protection—especially important in public procurement.
Automatic Number Assignment: System-generated assignment of unique bidder numbers during registration or qualification.
Bidder Identification: Linking the bidder number to company master data in the background without disclosure during the process.
Bid Anonymization: Bids are internally linked to bidder numbers without showing the bidder's name.
Access Control: Managing access to tender documents or bidding platforms based on bidder numbers.
Duplicate Check: System validation to prevent duplicate bidder number assignments.
Export and Reporting: Generating lists and reports on assigned bidder numbers for procedural documentation.
Archiving and Traceability: Secure storage and version history of bidder number assignments for later audits or reviews.
A municipal e-procurement portal automatically assigns a bidder number to every company registering for a tender.
During an online auction for industrial equipment, each bidder receives a number to submit bids anonymously.
A hospital procures medical equipment via an e-tendering system, where bids are evaluated only using bidder numbers.
An IT service provider maintains a complete list of all bidder numbers and corresponding registration data in its procurement tool for audit purposes.
