DD Form 254 (DD254): Contract security requirements, explained

December 30, 2025What a DD254 is, when you’ll see one, and how to avoid common mismatches.

What is a DD Form 254?

The DD Form 254 (Contract Security Classification Specification) is the document that communicates security requirements from the government to a contractor (or from a prime contractor to a subcontractor). It specifies requirements like classification level, safeguarding, access to classified systems, and special programs.

Every classified contract should have an associated DD254 (including flow-down for relevant subcontracts).

When is a DD254 issued?

  1. Solicitation: so bidders understand security requirements
  2. Contract award: reflecting final requirements
  3. Revisions: when security requirements, addresses, or key details change
  4. Final: when the contract is complete and retention is requested for a continuing need

What happens if my DD254 doesn’t match my FCL?

Mismatches between DD254 requirements and your FCL can prevent you from performing. Common issues include:

  • DD254 requires a higher clearance level than your FCL
  • DD254 requires safeguarding capability you don’t have
  • DD254 requires access to systems not authorized for your facility

The key is speed: review every DD254 immediately upon receipt to identify gaps and resolve them before they block program execution.

How does FCL Simple help with DD254 management?

  • Digital DD254 repository: searchable storage for all DD254s
  • Validation: error checking to catch incomplete or inconsistent information
  • Contract lifecycle tracking: active contracts, expirations, revision history
  • Clearance requirements visibility: identify personnel clearance needs based on DD254 requirements
  • Subcontract flow-down tracking: manage downstream DD254 issuance
