Customer Reviews
Mostly good, one small issue
I purchased credits for the Real-time Phone Verification and overall, I'm satisfied. The accuracy was high, and the API was quick. Integration was pretty smooth, but the documentation could use a few more examples for less common use cases. Still, it definitely improved our user data quality, and the support team was helpful when I had a question.
So easy to use!
I used the Phone Validation API for my new project, and it was incredible! Integration was a breeze, and the documentation was super clear. It just worked perfectly right out of the box. I'm definitely coming back for more credits, and I've already told my dev friends about it!
Good for checking numbers
I tried out the Fake Number Checker for a small list of contacts I had. It was pretty straightforward to use. The results seemed accurate, and it helped me clean up some old data. Nothing fancy, but it got the job done without any fuss.
Great value for a startup
As a first-time buyer, I was looking for the most bang for my buck. The free API credits for signing up were a huge plus, letting me test things out without commitment. I then got an annual subscription for the Phone Validation API, which saved me about 15% compared to monthly. It felt like a smart investment for my budget-conscious startup.
Consistent performance, as usual
I've been using NumCheckr for a while now, mainly their VoIP Detection Service. This latest purchase of more credits for a new batch screening was just as reliable as my previous orders. The service consistently delivers fast and accurate results, which is why I keep coming back. It's a solid tool I can count on for my user onboarding verification.
Detailed breakdown of my experience
I decided to use the Batch Number Screening service for around 5,000 numbers. Ordering credits was simple through the dashboard, and I got the volume discount, which was nice. I uploaded my list, and the processing took about 3 hours, which felt reasonable for the size. The results were clear, identifying various numbers as VoIP or disposable, which was exactly what I needed for fraud prevention. I also tested their Carrier Lookup Service on a few numbers and it was spot on. The API documentation was comprehensive and easy to follow for integrating the Fraud Prevention API into our system. I didn't need customer support this time, but the overall user interface of the dashboard was intuitive. It's a solid tool for anyone needing to clean up phone data and prevent fake registrations.

is numcheckr better than ipqs for catching burner phones? trying to decide which one to use.
Got a promo code from an affiliate site. Where do I actually type that in when I'm paying?
How quickly can I actually get this integrated? Is it a pain or pretty straightforward?
hey, anyone know if numcheckr works outside the US? like for UK or Australia numbers?
