The History & Meaning Behind US Government Agency Flags

The DVA seal also features a bald eagle; however, it holds flags in its talons instead of arrows. On the left is the Betsy Ross flag, the first official flag of the United States, while on the right is the modern American flag. These two flags represent the country's development and its history. Above the eagle are five gold stars in a pentagon shape, symbolizing the branches of the US military at the time of the seal’s creation: the Army, Navy, Air Force, Marine Corps, and Coast Guard.

Just like the flags of the DoD and DVA, DHS flags consist of the agency’s seal centered on a blue background. The current seal and flag were adopted on June 19, 2003.

The Department of Homeland Security was created in November 2002, replacing the Office of Homeland Security, which itself had only been established in October 2001. Until 2003, the agency had been represented by a modified version of the United States Great Seal. The department’s unique seal, adopted in June 2003, was the result of a collaborative effort involving DHS leaders and employees, the US Commission on Fine Arts, the Ad Council, and Landor Associates. 

The seal on the DHS flag depicts a blue and white bald eagle with its wings outstretched, holding an olive branch with 13 leaves in its left talon and 13 arrows in its right talon. On the eagle’s chest is a shield divided between a sky, mountainous landscape, and water, representing the United States' land and oceans. Inside the upper sky portion are 22 white stars, symbolizing the 22 bureaus that were merged to form the modern Department of Homeland Security. 

The US Department of State flag is very similar to the Department of Homeland Security's, as they are both based on the Great Seal of the US. This flag also depicts an eagle holding an olive branch with 13 leaves, and 13 arrows in either of its talons. Above the eagle is a ring containing 13 white stars, which also symbolize the original colonies.

The DHHS flag features the agency’s symbol, drawn in gold, circled by the department's name. The symbol itself is a stylized drawing of a bald eagle, with the innermost lines mimicking human faces. This represents the agency’s mission and responsibility for the welfare of the American people. The seal was formally adopted on May 14, 2014. 

In the center of the dark green flag is a bald eagle holding a shield that contains an anchor, a scale, 13 stars, and a key. The scales on top of the anchor represent justice, while the key is in honor of the Treasury key, a traditional symbol of the department. The 13 white stars symbolize the original 13 colonies.

On the left of the shield is an oak branch for strength, and an olive branch on the right for peace. Below the shield is a banner bearing the year “1789”, which marks the founding of the Department of the Treasury.

The seal depicts a shield flanked by two laurel branches, representing honor and distinction. The branches have 46 leaves in total, in reference to the number of US states that existed at the time of the FBI’s founding in 1908. Inside the shield is a set of scales, symbolizing justice. Below the scales are five vertical red and white stripes, mimicking the national flag of the United States. The shield and laurels are surrounded by 13 gold stars, representing unity and the original 13 colonies.

The US Border Patrol flag has the agency’s emblem in the center, surrounded by 23 gold stars. The stars represent the number of subdivisions that make up the Border Patrol. Below the emblem is the date “May 28, 1924”, the day on which the agency was established. Inside the emblem is the name of the agency on top of a map of the continental US.

The National Security Agency was established in 1952 and used the Department of Defense’s seal. A design competition for a unique agency seal was proposed in 1955, but was not carried out. A new seal was adopted in 1963, yet the NSA claims that no information about its origin remains today. The NSA’s first flag was created in 1964 and bore the same seal.

In 1965, NSA Director Marshall Carter summoned Richard Nachman, who worked in the agency's graphic design branch. He was tasked with redesigning the agency’s seal, which he submitted the following year. In September of 1966, the new seal was officially adopted, with the agency’s flag updated to bear the new emblem. 

The NSA flag depicts the agency’s heraldic insignia on a light blue field, which displays a bald eagle with its wings outstretched and an American flag shield on its chest. The eagle is holding a large key within its talons, which symbolizes security and the key of Saint Peter, one of Jesus’ apostles. 

The CIA flag features the organization’s seal on a dark blue background. The seal has a large white shield in the center, representing defense. In the center of the shield is a compass rose, symbolizing the gathering of information from all over the world in one central location. The bald eagle on top of the shield indicates that the agency is always on alert.

Despite having existed for over 100 years, the Food and Drug Administration didn’t have an official agency seal or flag until very recently. The FDA’s first official seal and its corresponding flag were adopted in 2026 to commemorate the 120th anniversary of June 30, 1906, when the agency was founded. In fact, these 120 years of service are represented by the 120 small gold triangles which line the inside of the seal’s outer rim.

The central emblems of the FDA flag and seal include a large white shield, representing virtue and transparency, with a snake coiled around a staff in the center. The snake-and-staff icon is known as the Staff of Asclepius, a widely used symbol from ancient Greece that represents the practice of medicine. The Staff of Asclepius is on top of an open book, which stands for knowledge. Around the snake is a circle of eight stars, each representing a product area under FDA regulation.

The flag of the Food and Drug Administration shares similarities with other government flags, including the portrayal of a bald eagle, the agency's name printed inside the seal’s rim, its motto, and the date of its founding. However, the FDA flag has some wholly unique design elements, such as the double-helix DNA strand to the left of the white shield, complemented on the right by sheaves of grain. The DNA strand symbolizes scientific progress and medical technology, while the grain stands for the FDA’s protection of the American food system.
