Doesn't seem like a valid format. I cannot find a country for which ZL stands for. – chempatent1981 Mar 28 '17 at 7:41

I have had a guess at what the underlying question is, and tried to make this explicit in the question. But please feel free to re-clarify. – Maca Mar 28 '17 at 21:30
This is likely Chinese utility model CN203999849. The number you refer to is the application number.
ZL (zhuānlì) refers to the granted version of an application number. So ZL 201420446264 is the granted utility model of application number 201420446264, which is utility model 203999849.

@ASHUVERMA I have had some occasion in the past to work with Chinese applications, so I just happened to recognise the format of the number. The utility model number was just a Google Patents search based on the application number. – Maca Mar 29 '17 at 5:56
