Every apostille in the state comes from one place: the Colorado Secretary of State, headquartered in downtown Denver. Since April 2018, the office has issued a single combined certificate that serves as an apostille in Hague Convention countries and as an authentication everywhere else. Knowing the Colorado apostille requirements before you submit is what keeps a request on schedule, and our apostille and legalization services handle that groundwork for you.
In-Person Submission in Downtown Denver
The department allows you to drop off your Denver apostille paperwork in person at the office in the city’s downtown area. This service has an additional fee, and you must submit it before the 4:30 p.m. cut-off.
Mail Requests and Return Envelopes
The office also allows mail requests, which are cheaper and more convenient than walk-ins but have longer turnaround times. For faster, more secure delivery of your Denver apostille, include a prepaid, trackable return envelope with your submission.
Colorado Documents Only
The Colorado Secretary of State in Denver can apostille only documents issued within the state. It cannot authenticate out-of-state paperwork or federal records.
