What makes an Indian mobile number valid?

An Indian mobile number is exactly 10 digits and must begin with 6, 7, 8 or 9. After dialling codes are removed, anything outside that pattern is not a valid mobile number under the National Numbering Plan.

Do I include +91 or a leading 0?

Both are accepted as input. The country code +91 and the trunk prefix 0 are dialling prefixes, not part of the 10-digit subscriber number, so the tool strips them before checking.

Can this tell me the operator or circle?

No. Mobile number portability means the first digits no longer reliably map to a fixed operator or telecom circle. This tool validates format only and does not perform a network lookup.

Why does my number fail validation?

The most common reasons are too few or too many digits, a leading digit of 0–5 (reserved for landlines and services), or stray characters. Re-check that the subscriber number is exactly 10 digits starting 6–9.

Is my number sent anywhere?

No. All checks run locally in your browser using JavaScript. The number never leaves your device and nothing is logged or transmitted.

India Mobile Number Validator

An Indian mobile number is a 10-digit subscriber number that, under India’s National Numbering Plan, must begin with 6, 7, 8 or 9. This free validator confirms a number is well-formed before you store it in a CRM, trigger an OTP, or attempt a delivery SMS — saving failed sends and bounced messages.

How it works

The validator normalises and checks the number in a few deterministic steps:

Strip every non-digit character (spaces, dashes, brackets, the +).
Remove a leading country code 91 or a trunk-access 0 if present, leaving the bare subscriber number.
Require the result to be exactly 10 digits.
Require the first digit to be one of 6, 7, 8, 9 — the ranges allocated to mobile services. Landlines and special services start with other digits and are rejected.

If all four pass, the number is a valid Indian mobile number, and the tool shows it in clean E.164 form (+91XXXXXXXXXX).

Notes and example

Mobile Number Portability (MNP) means you cannot reliably infer the operator or telecom circle from the leading digits any more, so this tool deliberately reports format validity only — not network ownership.

Example: input +91 98765 43210 normalises to 9876543210, which is 10 digits starting with 9, so it is valid and the E.164 form is +919876543210. Input 091234567 fails because, after stripping the leading 0, it is only 8 digits.

Everything runs locally in your browser — the number never leaves your device.
