⚠️ THE HIDDEN PROBLEM

Sending WhatsApp Messages to Dead Numbers?
You're Burning Money Every Day.

Every invalid number in your list costs you money, hurts your sender reputation, and wastes precious campaign time. Here's what's really happening behind the scenes...

💸

Wasted Marketing Budget

Up to 35% of bulk WhatsApp lists contain inactive numbers. That's ₹35 wasted for every ₹100 you spend on campaigns — money that goes straight down the drain.

📉

Low Response & Conversion Rates

When 1 in 3 messages never reaches a real person, your campaign metrics collapse. You think the offer is bad — but really, it's your list that's broken.

🚫

Risk of Getting Your Number Banned

Sending bulk messages to invalid numbers raises red flags. WhatsApp's detection systems can ban your business number — permanently killing your channel.

⏰

Hours Wasted on Manual Verification

Manually checking thousands of numbers? That's days of work that could be spent closing deals and growing your business.

🏆 WHY TRUST US

Built By Marketers, For Marketers

NUMBERCHECK was born out of frustration. Our founding team ran a digital marketing agency in India that relied heavily on WhatsApp campaigns for clients across e-commerce, real estate, education, and local businesses.

We were spending lakhs on WhatsApp marketing tools and bulk messaging — but up to 35% of our messages were going to dead numbers. Campaigns underperformed. Clients were unhappy. Our business numbers got banned twice.

We searched for a reliable WhatsApp number verification tool in the Indian market and found nothing that was fast, accurate, affordable, AND privacy-focused. So we built one ourselves.

Today, NUMBERCHECK serves 1,000+ marketers and agencies across India who have collectively verified over 5 million numbers. Our tool has helped businesses save crores in wasted marketing spend and achieve record-breaking campaign results.

We're not a faceless software company. We're marketers who understand your challenges — because we face them too. That's why every feature in NUMBERCHECK is designed to solve real problems that real Indian marketers deal with every day.

❓ GOT QUESTIONS?

Frequently Asked Questions

We've answered every question our users commonly ask. If you still have doubts, our support team is just a WhatsApp message away.

How accurate is NUMBERCHECK's verification?▼
NUMBERCHECK delivers 99.2% accuracy by checking numbers against WhatsApp's live database in real-time. Our verification engine is continuously updated to ensure you get the most accurate results possible. The small margin accounts for numbers that may change status between verification and your campaign launch — which is why we recommend verifying your lists right before each campaign.
Will using NUMBERCHECK get my WhatsApp number banned?▼
No — in fact, it does the opposite. NUMBERCHECK is designed with minimum ban risk technology. The verification process uses safe, non-intrusive methods that don't trigger WhatsApp's spam detection systems. Additionally, by helping you send messages ONLY to active WhatsApp users, it actually reduces your ban risk dramatically compared to sending blindly to unverified lists.
Is my data safe? Do you store my contact lists?▼
Absolutely not. We have a strict zero data storage policy. Your uploaded numbers are processed through our encrypted verification engine, and once you download your results, all data is permanently deleted from our servers. We never retain, sell, share, or use your contact data for any purpose. Your privacy is our top priority.
How many numbers can I verify?▼
With the annual license at ₹4,999, you get UNLIMITED verifications for the entire year. There's no cap on the number of numbers you can verify. Whether you need to check 100 numbers or 100,000 numbers — you're covered. Upload as many lists as you need, as often as you need.
How fast is the verification process?▼
NUMBERCHECK is built for speed. A list of 5,000 numbers typically completes in 3-5 minutes. Larger lists of 25,000+ numbers finish in under 10 minutes. Our optimized infrastructure processes multiple numbers simultaneously, so you're never waiting long — even for massive lists.
Does it work with international numbers or only Indian (+91)?▼
NUMBERCHECK works with numbers from any country. While it's optimized for Indian marketers and handles +91 numbers with the highest speed, you can verify numbers from any country code. This makes it perfect for agencies handling international clients or businesses targeting global audiences.
What file formats are supported for upload and download?▼
You can upload your number lists in CSV, Excel (.xlsx), or TXT format. You can also paste numbers directly into the tool. For downloads, you can export your verified results in CSV, Excel, or TXT — ready to import directly into your WhatsApp marketing tool, CRM, or automation platform.
₹4,999 per year — is it really worth it?▼
Let's do the math: If you send 10,000 WhatsApp messages per month and 35% go to inactive numbers, that's 3,500 wasted messages. At even ₹0.50 per message, you're losing ₹1,750/month — that's ₹21,000/year in wasted spend. NUMBERCHECK costs just ₹4,999/year and saves you ₹21,000+ annually. That's a 4x return on investment minimum. For agencies handling multiple clients, the savings multiply exponentially.
What happens when my annual license expires?▼
You'll receive renewal reminders before your license expires. Simply renew  annual rate to continue enjoying unlimited verifications. There are no auto-charges — you decide when and if you want to renew. We're confident you'll want to because of the value you'll experience throughout the year.
