They refer to a specific variant of the basic model (including freighter versions) and, in Boeing's case, also indicate the customer operator.

There are different versions of certain aircraft such as the 737-200/300/400/500/600/700/800/900. The second number shows which version it is, for example: the 737-900 has the longest fuselage of the 737's and the 737-500 is the smallest. In some cases, letters are used with the numbers: 767-300ER, or without the numbers: 747SP or C-130J.
Hope this helps.

The first number after the aircraft type shows which model of aircraft it is eg 757-200/757-300. The last 2 numbers are the customers numbers. Every customer has it's own number from a manufacturer, eg BAs customer number for Boeing is 36 so every Boeing aircraft they ordered them selves have 36 after them. eg 747-436, 757-236, 777-236 etc.

Somebody on here can proberbly give a better explanation.

...and since there are also other manufacturers than Boeing:
Airbus does not differ between airlines; There's for example the Basic model A319-100; And the two different variants -11X and -13X, for the CFM and IAE engine versions. The third number (which I named X) shows different variants of each model I believe.
Why is 10 afraid of 7? Because 7 8 9.
