How_to_Find_Supplier_Number.pdf

This instructional document from the Washington Suburban Sanitary Commission (WSSC) in Maryland provides guidance on locating supplier identification numbers required for participation in the agency's procurement processes. The document outlines a single method for suppliers to access their assigned Supplier Number through the WSSC Supplier Portal by logging into their account, navigating to the Supplier Details section within the WSSC Supplier Profile & User Manager, and locating the Supplier Number in the General header section of their profile. This supplier number is essential for submitting responses to WSSC contract solicitations, including the Water Treatment Services for HVAC and Biosolids for Eleven Locations opportunity, which requires sealed responses submitted via the WSSC eProcurement Portal at https://procurement.opengov.com/portal/wsscwater prior to 2:00 pm on Monday, August 3, 2026.

No additional pricing terms, set-asides, incumbency information, funding sources, or other salient contracting details are provided in this instructional file, as its primary purpose is to serve as a reference guide for suppliers seeking to identify and verify their account credentials within the WSSC procurement system.
