hi! nice website, tho at least for Hungary, it has some invalid area codes (for example: 06 07 408 3945 is invalid because there's no 7 area code here). also dont forget to patch your next.js version if u havent did it yet :) (there are 2 new vulnerabilities since react2shell was disclosed)

limaodev123•1mo ago

Thanks for the great feedback!

1. You are totally right about the Hungarian area codes. I relied on some generic regex patterns, but I will refine the Hungary logic to exclude the '07' prefix.

2. And thanks for the heads-up on the Next.js security patch! I'll check my dependencies and update the version today.

Really appreciate you taking the time to test it out!

Hi HN! I'm the creator of this tool.

I built this because I was frustrated that most "random number generators" create invalid phone numbers (e.g., US area codes starting with 0 or 1) which kept breaking my QA validation logic.

Key features:

- Validates Area Codes & Exchange Codes (US, UK, CN, etc.)

- 100% Client-side (Privacy focused, no data sent to server)

- Bulk Export to CSV, JSON, and TXT

It's built with Next.js. I'm actively looking to improve the validation rules for more countries (as noted by quadVision below!), so any feedback is welcome!
