IsValid is a validation API service for developers who need to quickly verify data formats without building their own validators. It offers 40+ endpoints covering financial identifiers (IBAN, BIC, ISIN, CUSIP), international standards (ISBN, ISSN), technology formats (UUID, JWT, QR codes), regional codes (PESEL, REGON, VAT), and more.

The service works on a freemium model โ€” 100 free API calls per day, no credit card required. Users manage API keys through a dashboard with usage analytics showing daily call volume and per-endpoint breakdowns.

Veriphone features and specs

  • Comprehensive Data Coverage
    Veriphone provides an extensive database that covers a wide range of phone numbers globally, allowing users to validate numbers from numerous countries.
  • Real-time Validation
    The service offers quick, real-time phone number validation, which is beneficial for applications requiring immediate verification.
  • Detailed Response
    Veriphone's API returns detailed information about each phone number, including carrier, country, and line type, which can enhance user data quality.
  • Easy Integration
    The API is straightforward to integrate into various systems and applications, supported by comprehensive documentation and examples.
  • Scalability
    Veriphone handles small to large volume requests, making it suitable for businesses of different sizes.

Possible disadvantages of Veriphone

  • Cost
    While Veriphone offers a free tier, extensive use, especially for high volume requests, requires a paid plan which might be expensive for small businesses or individual developers.
  • Dependency on Third-Party Service
    Relying on an external service for phone number validation can introduce a point of failure and may affect system availability if Veriphone experiences downtime.
  • Privacy Concerns
    Using a third-party service to validate phone numbers could raise privacy issues, especially if sensitive user data is involved.
  • Limited for Non-Phone Data
    While excellent for phone number validation, Veriphone is not designed for validating other types of data, limiting its utility to this specific function.

Questions & Answers

As answered by people managing Veriphone and IsValid.dev.

What makes your product unique?

IsValid.dev's answer:

IsValid offers 70+ validators in a single API โ€” covering financial identifiers (IBAN, BIC, ISIN, LEI), international standards (ISBN, ISSN), technology formats (UUID, JWT, QR codes), tax numbers (VAT, REGON, PESEL), credit cards, phone numbers, and more. No need to integrate multiple services for different data types.

Why should a person choose your product over its competitors?

IsValid.dev's answer:

How would you describe the primary audience of your product?

IsValid.dev's answer:

Developers and software teams building applications that handle user input, financial data, or international identifiers โ€” particularly in fintech, e-commerce, and SaaS products.

What's the story behind your product?

IsValid.dev's answer:

Which are the primary technologies used for building your product?

IsValid.dev's answer:

Next.js, Fastify, PostgreSQL, Docker
