DND Filter is a leading platform offering free and efficient DND (Do Not Disturb) number filtering services to ensure businesses comply with TRAI (Telecom Regulatory Authority of India) guidelines. Our easy-to-use online tool helps businesses, marketers, and service providers remove DND-registered numbers from their contact lists before launching SMS or voice call campaigns.

At dndfilter.com, users can upload mobile number lists (up to 50,000 numbers at once) and instantly check which numbers are registered on the National Do Not Call (NDNC) registry. This process protects your brand from penalties, maintains customer trust, and improves the success rate of your outreach campaigns.

We serve various industries, including marketing agencies, e-commerce, real estate, healthcare, financial services, education, and more. In addition to DND filtering, we also offer support for Bulk SMS services, DLT registration guidance, and verified WhatsApp messaging.
