011 is the international calling code from North America. 44 is the country code for the United Kindom. 20 (or 020 when dialling within the UK) is the area code for London. So, a number like 011 44 20 3890 1234 would be a telephone number in London, UK.
This is the UK code. If you're calling from within the UK the 0 is kept, 020, then the number. If calling from outside the UK, you use the international access code, then DROP the 0, and enter the 20 and then the number. Good luck.
