About Us

The North American Numbering Plan used telephone number formats that included the name of the central office to which each telephone was connected. Traditionally, these names were often town names, village names, or other locally significant names, but larger communities that required more than one central office, may have used other names for each central office, such as Main, East, West, Central. Names were convenient to use and reduced errors when telephone numbers were exchanged verbally between subscribers and the operator.

North American Numbering Plan is a telephone numbering plan that encompasses 25 distinct regions in twenty countries primarily in North America, including the Caribbean and the U.S. territories. Not all North American countries participate in the NANP. Each participating country forms a regulatory authority that has plenary control over local numbering resources.

Of all states or territories, the U.S. state of California has the largest number of area codes assigned, followed by Texas, Florida and New York, while most countries of the Caribbean only use one. Many Caribbean codes were assigned based on alphabetic abbreviations of the territory name.

The goal of the North American Numbering Plan was a system by which telephone subscribers in the United States and Canada could themselves dial and establish a telephone call to any other subscriber without the assistance of switchboard operators. For this, each central office in the served territories was assigned a unique designation of similar form to all others.
