Why do we dial 911 for emergencies? The number 911 was chosen because it’s short, easy to remember, and can be dialed quickly. Before 911, people had to call local police or fire departments directly, which took longer and could be confusing. The first 911 call was made in 1968 in Haleyville, Alabama. Since then, it has become the standard emergency number in the United States and many other countries. This system saves lives by connecting callers to emergency services like police, fire, and medical help. Knowing how and when to dial 911 is crucial for everyone.

Dialing a phone number is something many of us do daily without much thought. However, the history behind this simple action is quite fascinating.
- 01
The first rotary dial was invented in 1891 by Almon Brown Strowger. This invention revolutionized how people made phone calls.

How Dialing Works
