# What is a Lottery Number?

A lottery number is a unique sequence of 32 characters in hexadecimal format. These numbers are used by the DOE to match studentsâ€™ lottery numbers with their school preferences.

The first eight characters provide 168, or over 4 billion, possible combinations of lottery numbers, so the chances that two students will have the same numbers are low. In addition, the system will never use any numbers beyond these initials to compare studentsâ€™ lottery numbers; thus, any duplication is unlikely to have any significant impact on student outcomes.

#### Good Numbers

A good lottery number is one that is in the first quartile of all ordered numbers. Specifically, a number that starts with 0 is in the first 1/16th of all lottery numbers (6.25%), and one that begins with F in the last 1/16th.

A bad lottery number is one that is in the second quartile of all ordered numbers. Similarly, a number that starts with 3 is in the first quartile of all lottery numbers.

#### Overdue Numbers

Overdue numbers are those that havenâ€™t been drawn in recent weeks. These numbers are typically considered unlucky because they havenâ€™t been drawn much recently.

#### Hot Numbers

Hot numbers are those that have been drawn the most frequently over the course of a few draws. The likelihood that these numbers will be drawn again is greater than other numbers, and you can therefore feel more confident playing them.

However, this is not an automatic strategy that can guarantee you will win. You need to make calculated guesses about what combination will win in each draw. The best strategy is to play with a mathematically sound combination.
