Why it Matters

Phone numbers arrive in a dozen messy shapes — with +91, a leading zero, spaces, dashes, or brackets. Storing them inconsistently breaks lookups, deduplication, and SMS delivery. Normalising Indian numbers to a canonical format like E.164 makes data clean and reliable, and validating the mobile rule catches typos before they cause failed messages.

What this tool does

The Indian Phone Formatter cleans up messy Indian phone numbers and formats them into five canonical styles — E.164, international, national, RFC 3966, and plain — while detecting whether each is a mobile, landline, or toll-free number.

How it works

It strips the country code (+91 or 0091), a leading STD 0, and any spaces, dashes, or brackets, then validates the result against the Indian mobile rule (10 digits starting 6–9) and classifies the number. You can paste up to 50 numbers at once. All processing is a pure function that runs fully offline.

Privacy

Everything runs locally in your browser. No phone numbers are uploaded, logged, or stored.

Frequently Asked Questions

What makes an Indian mobile number valid?
An Indian mobile number is exactly 10 digits and starts with 6, 7, 8, or 9. The tool strips any country code (+91 or 0091), a leading STD 0, and formatting characters, then checks the remaining 10 digits against this rule. Numbers that fail are still formatted but flagged so you can review them.
What is E.164 format and why use it?
E.164 is the international standard for phone numbers: a plus sign, the country code, and the national number with no spaces — for example +919876543210. It's the safest way to store numbers in databases and send them to SMS gateways and APIs, because it's unambiguous worldwide.
Does it detect landline and toll-free numbers?
Yes. Numbers beginning 1800 or 1860 are classified as toll-free, 10-digit numbers starting 6–9 as mobile, and other 8–11 digit numbers as landline. The classification is heuristic and based on format, not a live carrier or directory lookup.
Can I format many numbers at once?
Yes. Paste up to 50 numbers, one per line or separated by commas, and each is cleaned, classified, and formatted independently. Nothing is uploaded — it all happens in your browser.
Is my data stored anywhere?
No. All parsing and formatting runs locally in your browser. The numbers you enter are never uploaded, logged, or stored — refreshing the page clears everything.
