Many Chinese believe in lucky numbers. Mostly base on the pronunciation of number itself. These numbers can be anything, day of the year, house or apartment numbers. Phone or license plate even serial numbers on money bills. This is way beyond the fact most of the price tags end with 98 or 88. Such number are not FengShui based but people just love them. Here are some examples: 

168: a road of prosperity or be prosper together. Many areas in China, charged telephone service numbers starts with 168 (similar to 900 number in America but has nothing to do with sex), the company who provides the serve are definitely getting a road of prosperity when you call them. 
289: Easy long-term prosperity, mostly in south east China and Hong Kong 
5: me, myself
518: I will prosper 
5189: I will prosper for a long time 
516289: I will get on a long, smooth prosperous road 
5918: I will soon prosper 
6: easy and smooth 
7: together
8: sudden fortune, prosperity 
9: long in time  

Some times not so attractive numbers can become attractive when form a phrase: 
48: 4 sounds like 'death', when placed in front of the prosperous 8 becomes 'determined to prosper'. Not bad at all for a new year's resolution.
