The 1st digit specifies the number of Junction present, exampe you can easily say that 1N4001 devices is a Diode, because it only has 1 Junction.
2N4002 for example, means that the device has 2 Junctiona, so you can say it is a transistor.

2N4123. NPN General Purpose Amplifier. 2N4123. This device is designed for use as general purpose amplifiers and switches requiring collector currents to 100 mA. Absolute Maximum Ratings* TA = 25°C unless otherwise noted.
Note: These ratings are limiting values above which the serviceability of any semiconductor.

How can we suppose to say the type of transistor by seeing the number?

@Ricky G.
Generally it is hard to find the type of transistor from number, You can get datasheet from google through this number. From that datasheet you can get all the specification.
