Customer Reviews
pretty good for checking numbers
got a sweet discount on my credit top-up, NumCheckr's Virtual Number Detector is solid, though wish updates were clearer.
Solid API, minor documentation issue
I recently implemented the VoIP Detection Service. Overall, the API performance was excellent and it accurately identified VoIP numbers in real-time, which is exactly what I needed. Integration was mostly smooth, but I found a small section in the API Documentation Access that was a bit vague regarding error handling, took me an extra hour to figure out. Customer service was responsive when I contacted them about it, though. The pricing is fair for what you get, and it definitely improved my user onboarding verification process.
Great value on annual plan
I was looking for a cost-effective way to validate phone numbers for my small business. The free API credits let me test it out, which was helpful. I decided to go with an annual subscription for the Phone Validation API and got the 20% discount. It made a real difference in the overall cost compared to monthly billing. The service itself is quick and reliable. Definitely felt like a smart purchase for the money, especially with that discount.
Good tool for fraud prevention
I used the Fraud Prevention API for my latest project. Setup was straightforward. It did what I needed it to do without any issues. Data was accurate. Saved me time.
Reliable as always, consistent service
This isn't my first time using NumCheckr; I've been a customer for about a year now. I needed the Real-time Phone Verification for a new rollout. Just like before, it integrated smoothly with my existing systems. The data quality was consistent with my previous experiences. I appreciate that they keep their database updated. It's why I keep coming back for my fraud detection and verification needs. Never had a major hiccup, which is crucial for my operations.
