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:

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.

Federal Records Center

Our Denver facility also serves as a Federal Records Center, storing and servicing records for more than 100 Federal agencies, including the courts. We offer "Pick-up and Delivery" and other special services, including tailored workshops.
