Advanced Random Data Generator

In the digital world, uniqueness is paramount. Universally Unique Identifiers (UUIDs) and Globally Unique Identifiers (GUIDs) are the backbone of modern software systems, ensuring that every piece of data, every transaction, and every entity can be distinctly identified across distributed environments. These 128-bit numbers are essential for databases, APIs, microservices, and any application where collision avoidance is critical.

Our powerful generator puts various UUID versions at your fingertips. Need a purely random identifier? UUID v4 is your go-to. Working with time-based sequences? Our (simulated) UUID v1 offers a timestamp-based structure. Need to generate an ID based on a name and namespace? UUID v3 (MD5-hashed) provides deterministic uniqueness. We also offer the standard Microsoft GUID format, typically a v4 UUID enclosed in braces, for seamless integration with Windows environments.

Stop worrying about ID collisions and focus on building robust applications. With our intuitive UUID/GUID generator, you can instantly create compliant and reliable unique identifiers for all your development and testing needs. Select your desired version, provide necessary inputs for v3, and get your unique ID in a flash. It's an indispensable tool for developers who demand precision and reliability.

From secure passwords and unique API tokens to placeholder data and test inputs, the need for random strings is ubiquitous in software development and data management. Manually creating truly random and diverse strings can be tedious and error-prone.

Developing or testing applications for the Polish market often involves handling PESEL numbers, the 11-digit national identification number. Ensuring your system correctly validates and processes these numbers is crucial. Our PESEL Generator creates syntactically correct, FAKE PESEL numbers that adhere to the official encoding rules, including birth date, gender information, and a valid checksum digit.

This tool is an essential asset for developers and QA engineers who need reliable test data. You can generate PESELs for specific birth dates and genders, or create completely random ones. Each generated number will pass standard validation algorithms, allowing you to rigorously test your input fields, database constraints, and processing logic without using real individuals' sensitive data. This ensures compliance and robust testing in a safe, controlled manner.

Streamline your testing for Polish applications with confidence. Our generator provides an unlimited supply of structurally valid PESEL numbers, saving you the time and risk associated with sourcing or creating test data manually. **Remember: All generated PESEL numbers are FAKE and intended solely for development and testing purposes. Do not use them for any official or fraudulent activities.**

When building financial, e-commerce, or administrative applications targeting Poland, correct handling of NIP (Numer Identyfikacji Podatkowej – Tax Identification Number) is essential. This 10-digit number is crucial for tax purposes, and your systems must be able to validate its structure. Our NIP Generator creates FAKE NIP numbers that are structurally sound and include a valid checksum control digit.

Empower your development and testing phases with an unlimited supply of correctly formatted NIP numbers. Using our tool, you can ensure your input validation, database storage, and business logic accurately process NIPs according to their defined algorithm. This helps prevent errors and ensures your application meets the necessary data integrity standards for Polish tax identification, all without using real, sensitive tax information.

Save time and mitigate risk by using our generated NIPs for all your testing scenarios. It's a vital utility for developers and QA teams working on Polish-centric systems. **Crucially, please remember that these NIP numbers are entirely FAKE and designed for testing and development environments only. They hold no real-world validity and should never be used for actual tax or official purposes.**

Need placeholder data for fields that might store driving license numbers, but don't require adherence to a specific country's complex format? Our Generic Driving License Number generator creates random strings that mimic the appearance of a structured identifier. This is useful for basic UI mockups or testing systems where the exact format isn't critical, but some structured data is preferred over a simple random string.

This tool produces a FAKE license number in a very generic format (e.g., `LLLNN/YY/NNNNN`). It's important to understand that this format is arbitrary and does **not** represent any official driving license standard from any country or region. It's purely for illustrative and placeholder purposes in non-critical testing environments.

Use these generated strings to quickly populate forms or database fields during early development stages when you need data that "looks like" an ID. **Please be aware that these are entirely FAKE, hold no real-world meaning, and should never be used in any context suggesting they are genuine driving license numbers. They are for superficial testing and mockups only.**

Testing payment gateways, e-commerce checkouts, and credit card validation forms is a critical part of software development. However, using real credit card numbers for testing is highly risky and strictly prohibited. Our Credit Card Number Generator provides FAKE card numbers for various major brands (Visa, Mastercard, Amex, Discover) that are mathematically valid according to the Luhn algorithm (checksum validation).

These generated numbers will pass initial client-side and server-side validation checks that rely on the Luhn algorithm and prefix/length rules for different card types. This allows you to thoroughly test your form logic, error handling, and data processing flows without ever exposing real financial data. It's an indispensable tool for developers and QA engineers building secure and reliable payment systems.

Ensure your payment integrations are robust and user-friendly by testing with our Luhn-valid fake card numbers. **EXTREMELY IMPORTANT: These credit card numbers are 100% FAKE, NOT VALID for any actual transactions, and carry NO MONETARY VALUE. They are solely for development and testing purposes. Attempting to use them for real purchases is fraudulent and illegal.**
