Interested people always ask;

How many states are in USA now? and What are the all US states list?

The United States of America is comprised of 50 states, with a federal district Washington DC, five major territories, and various minor islands. Each state has its own state capital, traditions, and history.

Basically, the U.S. territories are scattered across the Pacific Ocean and the Caribbean Sea. So the USA stretching more than 3,000 miles from the Atlantic Ocean to the Pacific Ocean.

The 48 contiguous states and Washington DC, are in North America between Canada and Mexico, while Alaska is in the far northwestern part of North America and Hawaii is an archipelago in the mid-Pacific Ocean.

Each state and capital has its own constitution, based on the principles of the republic and the government, consisting of three branches: executive, legislative and judicial.

Under the United States Constitution, states have many powers and rights, such as controlling interstate trade, conducting elections, forming local governments, and approving constitutional amendments, but sovereignty is shared with larger federal governments.

Every US state is represented by two senators, while representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census.

In addition, each state has the right to select a number of voters to vote in the Electoral College, the body that elects the president of the United States, equal to the total of representatives and senators in Congress from that state.

The Constitution grants Congress the authority to admit new states into the Union. 

Since the establishment of the United States in 1776 by Thirteen British Colonies, the number of states has expanded from the original 13 to 50.

In table: list of 50 states and capitals

Note: USA State Postal Abbreviations are all two letters, and these two letters are always capitalized without any periods. These official state abbreviations have all been standardized by the United States Postal Service.

As an example, New York is shortened as NY and not as N.Y. with periods after each letter. Similarly, the Alabama abbreviation is AL (and not Al).

US Territories and Commonwealth

Outside of the 50 main states in the Union, the United States has several territories in different parts of the world too. These territories may not be official states, but they still adhere to the same formula of two capital letters for their official abbreviations.

Territories of the United States

In addition to the 50 states and the federal district, the United States has sovereignty over 14 territories. Five of them (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands) have a permanent, nonmilitary population, while nine of them do not.

With the exception of Navassa Island, Puerto Rico, and the U.S. Virgin Islands, which are located in the Caribbean, all territories are located in the Pacific Ocean. 

One territory, Palmyra Atoll, is considered to be incorporated, meaning the full body of the Constitution has been applied to it; the other territories are unincorporated, meaning the Constitution does not fully apply to them. 

Ten territories (the Minor Outlying Islands and American Samoa) are considered to be unorganized, meaning they have not had an Organic Act enacted by Congress; the four other territories are organized, meaning they have had an Organic Act that has been enacted by Congress.The five inhabited territories each have limited autonomy and a non-voting delegate in Congress, in addition to having territorial legislatures and governors, but residents cannot vote in federal elections.
