    FAR 42.504—Postaward letters.

    Plain-English Summary

    FAR 42.504 addresses when a postaward orientation can be handled by a letter or other written communication instead of a formal conference. It explains that this approach is appropriate in some circumstances and that the written communication should identify the Government representative responsible for contract administration and call out any unusual or significant contract requirements. The section also ties postaward letters to the contract-change rules in FAR 42.503-2, making clear that the letter cannot be used to alter the contract or bypass proper change procedures. In practice, this provision gives agencies a simpler way to orient contractors after award when a meeting is unnecessary, while still ensuring the contractor knows who to contact and what special requirements matter most. It is mainly about efficient communication, clear administration, and avoiding confusion about contract terms or authority.

    Key Rules

    Letter may replace conference

    In some circumstances, the Government may use a letter or other written communication as postaward orientation instead of holding a conference. This is a discretionary alternative, not a universal requirement, and should be used when a written format is sufficient to convey the needed information.

    Identify administering representative

    The letter should identify the Government representative responsible for administering the contract. This helps the contractor know who will handle day-to-day administration, questions, and coordination after award.

    Highlight unusual requirements

    The written communication should cite any unusual or significant contract requirements. The purpose is to draw attention to items that may need special contractor attention, such as unique reporting, delivery, inspection, security, or coordination obligations.

    No unauthorized changes

    The rules on changes to the contract in FAR 42.503-2 also apply to postaward letters. The letter may explain or orient, but it cannot modify contract terms or create obligations outside the contract without proper authority and procedures.

    Responsibilities

    Contracting Officer / Government representative

    Decide whether a written postaward orientation is adequate in lieu of a conference, prepare the letter or other written communication, identify the contract administration representative, and ensure any unusual or significant requirements are clearly noted without making unauthorized contract changes.

    Contractor

    Review the postaward letter carefully, note the designated Government contact for administration, and pay close attention to any unusual or significant requirements identified in the communication. The contractor should also recognize that the letter does not itself change the contract.

    Agency

    Use postaward letters as an efficient orientation tool when appropriate, maintain consistency with contract-change rules, and ensure personnel understand the limits of written communications so that administrative convenience does not lead to improper contract modification.

    Practical Implications

    1

    A postaward letter can speed up onboarding when a meeting is unnecessary, but it must still give the contractor enough information to start performance smoothly.

    2

    The biggest risk is treating the letter like a vehicle for changing the contract; any substantive change still has to follow the proper change authority and procedures.

    3

    Contractors should not assume that every item mentioned in the letter is a new requirement unless it is already in the contract; the letter is primarily informational.

    4

    Identifying the contract administrator early reduces confusion about who can answer questions and coordinate performance issues.

    5

    If the contract has unusual or high-risk requirements, failing to highlight them in the letter can lead to missed obligations, performance problems, and avoidable disputes.

    Official Regulatory Text

    In some circumstances, a letter or other written form of communication to the contractor may be adequate postaward orientation (in lieu of a conference). The letter should identify the Government representative responsible for administering the contract and cite any unusual or significant contract requirements. The rules on changes to the contract in 42.503-2 also apply here.
