DD Form 1610, the Request and Authorization for TDY Travel of DoD Personnel, is the document that requests and approves a temporary duty trip before it happens. It states who is traveling, where, for how long, and at what estimated cost, and it carries the funding and approval signatures that make the travel official.
Because the 1610 becomes the basis for your orders and your later travel voucher, clean and complete entries save trouble downstream. You can prepare the form in the Universal PDF editor, adjust details as the trip firms up, and download a finished PDF for routing and signature.
What is DD Form 1610 used for
TDY travel needs written authorization before departure. The 1610 documents the official purpose of the trip, the itinerary, the authorized modes of travel, any special entitlements or variations, the estimated cost, and the appropriation that pays for it.
Today most routine TDY is authorized inside the Defense Travel System, so the paper or PDF 1610 is used mainly when travel runs outside DTS, for organizations or trip types that DTS does not handle, or where local procedure still calls for the form.
Who prepares and approves DD Form 1610
The traveler or an administrative section drafts the request, a resource or budget office adds the fund cite, and the designated approving official signs the authorization. The traveler carries copies during the trip, since the authorization number ties the eventual voucher back to the approved travel.
Both military members and DoD civilian employees travel on the 1610 when their organization uses it.
How to fill out DD Form 1610
Coordinate the trip details with your approving chain before completing the form. The key blocks cover:
- Traveler identification, grade or rank, organization, and duty station
- The purpose of the TDY, stated specifically enough to justify the trip
- Itinerary: the TDY location or locations, and the beginning and ending dates including travel time
- Authorized transportation modes and any special authorizations, such as rental vehicles or excess baggage, when approved
- Estimated costs for per diem, transportation, and other expenses
- The accounting citation from the funding office and the approving official's signature
Where the form goes
The signed 1610 is filed with the issuing organization and travels with you as your authority for the trip. After you return, it supports your DD Form 1351-2 travel voucher, and the finance office matches your claimed itinerary and expenses against what was authorized.
Follow your unit's routing procedures for signatures, and verify the current edition of the form with your administrative office or the official DoD forms site.
Frequently asked questions
The 1610 comes before the trip: it requests and authorizes the travel and estimates the cost. The 1351-2 comes after: it claims reimbursement for what you actually spent. The voucher is settled against the authorization.
Usually not. DTS generates travel authorizations electronically for the travel it covers. The 1610 remains in use where DTS is not used or not available, and some organizations require it for particular trip types.
Official travel should not begin without an approved authorization. Traveling first and seeking approval later puts your reimbursement at risk, so get the signed authorization before departure.
Significant changes to the itinerary, duration, or cost need an amendment through the same approval chain. Keep the amended authorization with your records so your voucher matches what was approved.
Yes. Open the PDF in the Universal PDF editor, type the request details, and download the completed file to route for the fund cite and approving signature.
