STD codes of Bihar and Jharkhand

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 Dhanbad that is 0326 and the number.
• From another country: dial +91, then the code without the 0, then the number: +91 326 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: Dhanbad (0326), Patna (0612), Muzaffarpur (0621), Gaya (0631), Bhagalpur (0641).

This list keeps the grouping of the telecom numbering plan, which is why two states or territories share this page.
