Do you know how many numbers there are in your cellphone number? Your cellphone number has 11 digits(数字). You may sometimes find it hard to remember your number. China has the longest cellphone numbers in the world, longer than the US or Australia. Why is that?

The 11 digits can be divided into three parts. Each part has a different meaning. The first three numbers tell you which mobile phone service provider you are using. For example, 135 is for the China Mobile Communications Corporation and 186 is for China Unicom. The fourth to the seventh digits tell you which area the number is registered (注册) in. And the last four digits are random. You may get the last numbers that you like or not.

The main reason for using 11 digits is that we have the largest population in the world. We once had 10 numbers. But as our population grew, there were not enough numbers for us to use. So we began to use 11 digits starting from 1999.

Cellphone numbers can be recycled. Usually, the service provider will reuse a canceled number after three to six months. If you call a number that you haven't contacted (联系) for a long time , you may find its owner has changed.

Besides China, Britain and Japan also use 11-digit cellphone numbers. But their numbers always start with 0. So they cannot create as many numbers as we can. Countries like the US, Australia and India use cellphone numbers with 10 digits, Canada's cellphone number are perhaps the world ' s shortest. They use seven digits.
