Issue with Kuwait number

[MagdEldinr]

I'm trying to validate this number +96557558430 and i'm sure it's a valid Kuwaiti number, however the validation returns False

Works with current code.

Python 3.7.6 (default, Jan  8 2020, 13:42:34) 
>>> import phonenumbers
>>> x = phonenumbers.parse("+96557558430", "")
>>> phonenumbers.is_valid_number(x)
True
>>> x
PhoneNumber(country_code=965, national_number=57558430, extension=None, italian_leading_zero=None, number_of_leading_zeros=None, country_code_source=0, preferred_domestic_carrier_code=None)
>>> phonenumbers.__version__
'8.13.18'
