How did the three numbers 911 change America?

Created in 1968, the 911 system is more than just three numbers, it's a modern rescue platform that saves millions of lives each year in the United States.

Before 1968, Americans had to call individual numbers for each agency such as police, fire or medical , causing delays in the event of an incident.

On July 1, 1968, the 911 telephone number officially launched, starting in the state of Alabama as a turning point in emergency telecommunications.

The three digits "911" were chosen because they are easy to remember, easy to dial, and do not overlap with any area or postal code in the country.

Just a few months later, the first 911 call in US history was made in the city of Haleyville on February 16, 1968.

The 911 system quickly spread across the United States, accompanied by reception centers, locating maps, and specialized dispatcher training.

Thanks to the integration of GPS technology, cell phones and digital maps, 911 callers can be accurately located in seconds.

Since the early 2000s, the United States has upgraded to E911 and NG911, allowing messages, photos, and data to be sent directly to the operator.

Today, more than 240 million calls to 911 each year are a clear testament to the importance of these three life-saving numbers to the American people.
