Dialing sequence, step by step

  1. 1

    Start with + on a mobile, or 011 when the United States network requires an all-digit access prefix.

  2. 2

    Add 91, the country calling code for India.

  3. 3

    Add the destination national significant number. Remove a domestic trunk 0 before a fixed-line area code. Do not add a 0 before a ten-digit mobile number in international format.

Use +91 for a saved Indian contact. When a US-origin network requires digits, use 011 before 91 and omit the Indian domestic trunk 0 from a fixed-line pattern.

Mobile and landline examples

X means a subscriber digit placeholder, so these patterns explain the transformation without publishing a private callable number. Save the + format; use the access-prefix format only for a call that starts in United States.

How the international format is built

Portable contact format

+ 91 + national significant number

The + represents international access. It is display notation, not one of the E.164 digits.

Digits-only call from United States

011 + 91 + national significant number

The first part routes out of the origin network and must not be stored as part of the destination.

E.164 limits the full international number to 15 digits and excludes international and national prefixes. See the E.164 and international-format guide for the reusable structure and regional exceptions.

Common mistakes for this route

  • Keeping a domestic fixed-line 0 after country code 91.
  • Assuming an Indian mobile number needs an extra area code before its ten-digit national number.
