The text

As prescribed in 4.607(c), insert the following clause:

Unique Entity Identifier Maintenance (OCT 2016)

(a) Definition. Unique entity identifier, as used in this clause, means a number or other identifier used to identify a specific commercial, nonprofit, or Government entity. See www.sam.gov for the designated entity for establishing unique entity identifiers.

(b) The Contractor shall ensure that the unique entity identifier is maintained with the entity designated at the System for Award Management (SAM) for establishment of the unique entity identifier throughout the life of the contract. The Contractor shall communicate any change to the unique entity identifier to the Contracting Officer within 30 days after the change, so an appropriate modification can be issued to update the data on the contract. A change in the unique entity identifier does not necessarily require a novation be accomplished.
