Not working for Indian zip code

[Rajjat]

SOme countires has zip code greater than 5. I tried to change the code with zip code limit 6. But still it gives an error " File "/usr/local/lib/python2.7/dist-packages/pyzipcode/init.py", line 167, in getitem
raise IndexError("Couldn't find zipcode: '%s'" % zipcode)". Is it build for only specific zip codes?- Thanks
