Updated Per Diem Names in DTS

As a reminder, nine Army installations are undergoing name changes through the end of 2023. Eight installation names have been officially changed, and one more is scheduled before the end of the calendar year.

Regardless of the actual effective date of the new Army installation name, in the Defense Travel System (DTS) the new per diem location name changes have already taken effect. These are actions that must be taken for travel documents to these nine installations:

• Trips entered in DTS after October 1, 2023: select the new installation name for the per diem location.
• Trips that began prior to October 1, 2023 that continued into October 2023: a second per diem location must be added to the itinerary using the new Army installation name for the travel dates of October 1, 2023 forward.
• Trips created prior to October 1, 2023 with travel dates beginning on or after October 1, 2023: must be updated to reflect the new per diem location Army installation name.

To update the per diem location travelers can amend their Authorization to change the per diem location before or during travel or update the per diem location upon return from TDY when the Voucher is created.

• Trips created prior to October 1, 2023 that ended by September 30, 2023 do not need to be updated.

Failure to update the Army installation per diem location for trips that occur on or after October 1, 2023 may result in DTS updating the per diem amount to $0. Per Diem location changes may also affect ILP rates, adjust other lodging rates, and add pre-audits. Review your document after making the per diem location change and contact your local Defense Travel Administrator if further assistance is necessary.
