Why do different places have diferent area codes?

for like the phone number..?Why do different places have diferent area codes?
Because

the more people

that have phone numbers

the more unique numbers

you will need to cover all of them.
SO people don't end up with the same phone number, plus phone calls have right place. Or peolpe would never get the place!Why do different places have diferent area codes?
So they will be different. You wouldn't want to share a line with someone... Ever see an I Love Lucy or other 50's television show? Hehe.. It was common to share a line with someone during that time in the United States.Why do different places have diferent area codes?
To state it simply, there would not be enough numbers available for all of the telephones in the world with only seven digits in a telephone number. Area Codes increase the number of numbers available by a thousand times over seven digit numbers.
Use your head.
The reason is simple.

Due to the high demand for phones.

Before everyone had phones... they just had the simple seven digit number.

However, more and more people wanted and bought phones.

Well eventually... they ran out of numbers to give to people.

I know what your saying.. 111-111 to 999-999 is ALOT of numbers.

But half of those numbers cant be used. For example: you cant begin any phone number with 911 because you would go straight to the police. And cities with 311 as a city help line (like chicago) you cant use any numbers beginning with 311 for that reason.



So in order to give more numbers Area Codes were installed

So now the same number might be in 2 seperate cities of the same state, or two diffrent states.



312-744-1752 CHICAGO- south

773-774-1752 Chicago -north

630-774-1752 - Wisconsin

Hope this helps :)
Just to make money. Also controls system overload
they have to divide the area code if the area is too large for one place. like texas 915 was divide to 6 different area codes now.
to distinguish them
