Standard for order
Although the first 13 states can be considered to have been members of the United States from the date of the Declaration of Independence – July 4, 1776 – or from the date on which they ratified the Articles of Confederation, they are presented here as being "admitted" on the date each ratified the present United States Constitution; most other such lists, including the 50 State Quarters program, do the same.
The admission dates for later states were set by either the act of admission or a later resolution issued under that act, except for Ohio, whose date of admission was determined by act of Congress in 1953 as March 1, 1803, when its legislature first met because of a clerical error of omission—the original act omitted setting a date that the act took effect.[note 1]
This list does not account for the secession of 11 states during the American Civil War to form the Confederate States of America, the subsequent restoration of those states to representation in Congress (sometimes called "readmission") between 1866 and 1870, or the end of Reconstruction in those states. Since their secession was declared illegal by the U.S. Supreme Court in the case of Texas v. White, the federal government does not give legal recognition to their having left the Union. The list also does not account for secessionist governments formed in two other states, as their Unionist governments generally remained in control.

- Congress recognized the state of Ohio on February 19, 1803 ("An act to provide for the due execution of the laws of the United States, within the state of Ohio", Seventh Congress, Session II, Chapter VII), but no formal date of statehood was set by the act of admission or a later resolution, as occurred with all other new states. On August 7, 1953, Congress passed a law retroactively setting the date of Ohio's statehood at March 1, 1803, the date when Ohio's first legislature convened.
- Unlike most later instances, this was not really a separate entity. When a state is formed within a territory and encompasses less than the whole territory, then the state is a new entity. When a whole territory becomes a state, the state is a new entity whose constitution, governor, legislature, are distinct from those of the territory that preceded it. However, the state of Vermont simply continued to exist as a state under the same state constitution that it had already, with the same governor and legislators continuing their terms of office. Rather than being a new entity, it was a state whose status changed to one that was admitted to the Union.
- Although the Republic of California, also known as the Bear Flag Republic, was declared on June 14, 1846 by Anglo-American settlers in Sonoma, that lasted only for 26 days, and never achieved internal or external recognition.
- The actual statehood proclamations for North and South Dakota were intentionally shuffled so it is unknown which state was admitted first. President Benjamin Harrison always refused to tell the order in which he had signed the two statehood bills. However, North Dakota's proclamation was published first in the "Statutes at Large", since it is first in alphabetical order.
