There is no specific country with the area code 016 as a standalone international dialing code. International dialing codes (country codes) typically consist of 1-3 digits and do not include leading zeroes. For example, the U.S. and Canada use +1, the UK uses +44, and Germany uses +49.
Possible Interpretations:
If the leading zero is part of a local area code:
Some countries, like the UK, have area codes starting with 0 for domestic dialing, such as 016 in the UK, which is part of regional codes like 0161 for Manchester.
Check Context:
If you meant +16, this is not assigned as an international country code.
Ensure you’re not confusing an area code within a country with a full international dialing code.
