At what location are passport applications accepted?

The correct answer highlights that designated post offices are official locations where passport applications are accepted. In the United States, many post offices have been authorized by the U.S. Department of State to process passport applications. This includes assistance in filling out the application forms, collecting necessary documentation, and submitting the applications on behalf of applicants.

Designated post offices provide a convenient option for individuals to apply for passports, often with extended hours and locations that may be more accessible than other facilities. While other governmental or community institutions like public libraries, courthouses, or Department of Motor Vehicles may offer various services, they usually do not have the same authorization specifically to accept passport applications, which makes designated post offices the correct and most relevant choice for this question.
