How to write a India number in E.164
- Remove spaces, dashes, dots and brackets so only digits are left.
- If the number starts with the trunk prefix 0, remove it. It is only used when dialling inside India.
- Put +91 in front. The result has 10 digits after the country code for a mobile.
So 081234 56789 becomes +918123456789. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.
Mobile or landline?
India allocates separate number ranges to mobiles and landlines, so a numbering-plan check reads the line type straight from the digits, for free. That type describes the range the number came from. It doesn’t prove the number is connected today.

Common questions
- What is the country code for India?
- The country calling code for India is +91. When you call India from abroad, dial your international prefix (or +) followed by 91 and the number without its leading 0.
- How many digits is a India phone number?
- A India mobile number has 10 digits after the country code +91, the same as a landline. Written for dialling inside India, a number gains the trunk prefix 0 in front.
- How do I write a India number in international format?
- Start with +91, drop the leading 0, then add the rest of the number. The mobile number 081234 56789 becomes +91 81234 56789, or +918123456789 in E.164, the form most CRMs and SMS tools expect.
- Can you tell if a India number is a mobile?
- Usually, yes. India numbers come from ranges allocated separately to mobiles and landlines, so a numbering-plan check reads the line type from the digits. It tells you what the range is for, not whether the number is in service.
