National Archives at Denver


We Moved:
The National Archives at Denver is open to the public at our new location:

  • 17101 Huron Street, Broomfield, CO 80023
  • The main number for the Archives is 303-604-4740
  • E-mail:

Our research room hours for both genealogy and research of our historical textual records is 8:30-4:00 p.m., Monday-Friday, except public holidays.

Take I-25 North to Exit 229 (Lafayette/Brighton), go up the ramp. Turn left at the stop light, cross over the interstate and turn right at the first opportunity (Huron Street, approximately 1/8 mile from the interstate). We are the blue and white building to the northwest. The road narrows right after you cross I-25, and then there is a Right Turn only lane; this is Huron St. and where you need to turn. There is no sign that points to our facility. If you go past Children's Hospital, you have gone too far.

We have a number of ways that we can assist you:

  • Learn about our Archival Holdings
    Our archival holdings are comprised of Federal records that date from the mid-1800s to the late 1900s received from over 100 Federal agencies and courts.
  • Learn about our Records Center
    We maintain non-current records from Federal agencies and courts and provide temporary storage of retired Federal records.

Archives Division

Our Regional Archives has both a Microfilm Research Room and an Archival Research Room. We have extensive microfilm holdings for genealogy research and general historical interest.
