STD codes of Karnataka

How to use these codes

• From a mobile or a landline in India: dial the STD code with its 0, then the landline number. For Bangalore that is 080 and the number.
• From another country: dial +91, then the code without the 0, then the number: +91 80 and the number.
• Mobile numbers have no STD code. Dial the 10 digits as they are.

The STD code and the landline number together always make 10 digits, so a shorter code leaves room for a longer number. The shortest codes in this list: Bangalore (080), Tumkur (0816), Udupi (0820), Mysore (0821), Mangalore (0824).
