How the phone number cleaner works
2. Country codes are added
Indian numbers become 91XXXXXXXXXX from +91, 091, 0091, 0 or 10-digit formats. Numbers with + or 00 keep their own country code, like 971, 44 or 1.
3. Landlines and duplicates removed
Landline, toll-free and premium numbers are detected and removed. The same number written in different formats is kept only once.
4. Export a clean list
Copy the result or download CSV or TXT, for all numbers or one country at a time. A full report shows what was merged, removed or rejected.
Phone number formats we clean

Frequently asked questions
Is the phone number cleaner free?
Yes. The Smart Number Filter is free to use and needs no sign-up.
Are my numbers uploaded anywhere?
No. Cleaning runs inside your browser, so your numbers are not sent to our servers.
How do I add 91 to Indian mobile numbers in bulk?
Paste the list and click Clean Numbers. Every valid Indian mobile is converted to the 91XXXXXXXXXX format, ready for WhatsApp and SMS tools.
Can it remove duplicate numbers?
Yes. Numbers are compared after normalization, so +91 80778 46151 and 08077846151 count as the same number and appear only once.
Can it remove landline numbers?
Yes. Landline, toll-free and premium-rate numbers are detected and removed. You can turn this off if you want to keep them.
Does it work for numbers outside India?
Yes. Numbers written with + or 00 are detected for every country. For numbers without a country code, choose their country from the dropdown.
