Numverify API Coupon Codes November 2026 – 32 Verified Offers

Super easy to use!

I signed up for the Professional Plan and it was fantastic! The real-time validation worked perfectly for my app, and the API Key Management dashboard is so clear. I'm definitely going to keep using this and tell all my developer friends. So glad I found Numverify!

Good for quick checks

I used the Free Tier for validating some US numbers. It worked fine for basic checks. Getting the API key was quick. Wish it had more requests though.

Solid service, few hiccups

I opted for the Professional Plus Plan for its advanced features. The carrier detection and location lookup were quite accurate, which was a big plus for my needs. The API documentation was mostly clear, though I did find a couple of sections a bit vague, leading to some trial and error. Customer service was responsive when I had a question about rate limits, which was reassuring. Overall, a reliable service that performs well, but there's always room for minor improvements in documentation clarity.

Decent service, some issues

I signed up for the Basic Plan to use the Phone Number Validation API in my app. Integration was fairly straightforward with the API Documentation, and the real-time validation is definitely a plus. However, the accuracy for some international numbers wasn't always perfect, which meant I still had to do some manual cleaning. The usage statistics dashboard is useful for keeping track of my calls. Overall, it's a solid tool for the price, but there's room for improvement on global data consistency. I'd consider upgrading to the Professional Plan if those issues were tightened up a bit.

Professional Plan setup was smooth

I signed up for the Professional Plan last month to integrate their Phone Number Validation API into our system. The API documentation was clear, which made the integration fairly straightforward for our dev team. I appreciated the Developer Sandbox for testing before going live. We received our API Key almost instantly after signup. Data accuracy has been good so far for both national and international lookups. Their usage statistics dashboard is also helpful for monitoring calls. Delivery of the API key was immediate, and integrating took about a day.

Good value, some delays

I bought the Basic Plan. The service itself was good for phone number validation. However, setting up the API key took longer than expected to activate. Once active, it worked well. Decent value for the price.

Good for basic checks

Needed a quick way to check some numbers for a personal project. Grabbed the Basic Plan. It was alright. The JSON API Access worked, though setting it up was a little less intuitive than I hoped. Took me a bit to figure out the exact endpoint. Overall it does what it says. Just wish the instructions were a tiny bit simpler.

API key worked fine

Got the API key for the Phone Number Validation API a few days ago. Was pretty easy to set up and start using. The documentation helped out a lot, didn't have any major issues getting it to work in my project. Overall, it was a smooth experience.
