Working with unique identifiers is a fundamental part of modern software development. Whether you’re building distributed systems, mobile applications, or payment processing software, having reliable tools to generate and validate various ID formats is essential.
In this article, we’ll explore 5 powerful ID and identifier tools from ElysiaTools that every developer should have in their toolkit.
1. UUID Generator
UUID Generator is your go-to tool for creating universally unique identifiers. It supports all three commonly used UUID versions:
- UUID v1 – Time-based UUIDs that combine timestamp and node information
- UUID v4 – Random UUIDs, the most commonly used variant
- UUID v5 – Namespace-based UUIDs for deterministic generation
Generate up to 100 UUIDs at once, perfect for bulk database seeding, API testing, or distributed system development.
2. UUID Validator
UUID Validator helps you verify and analyze UUID strings. It goes beyond simple format checking by:
- Detecting the UUID version (v1-v5)
- Validating the variant according to RFC 4122
- Extracting timestamp information from v1 UUIDs
- Providing detailed validation reports
This tool is invaluable when debugging API responses or validating user input in your applications.
3. IMEI Generator
IMEI Generator creates valid 15-digit IMEI numbers for mobile device testing. Each generated IMEI:
- Passes the Luhn checksum validation
- Can use custom TAC (Type Allocation Code) prefixes
- Follows proper IMEI structure conventions
Generate up to 100 IMEIs at once for mobile app development, device simulation, or QA testing scenarios.
4. IMEI Validator
IMEI Validator verifies IMEI numbers using the Luhn algorithm. Simply enter any 15-digit IMEI and get instant feedback on:
- Format validity
- Checksum correctness
- Type detection (IMEI vs IMEISV)
Perfect for validating user-reported device identifiers or checking IMEI data quality in your systems.
5. Credit Card Generator
Credit Card Generator creates test credit card numbers for development and testing purposes. It supports:
- Visa – 13 and 16 digit variants
- MasterCard – Multiple prefixes
- American Express – 15-digit format
- Discover, JCB, China UnionPay
All generated numbers pass Luhn checksum validation but are NOT real cards – they’re designed specifically for testing payment flows, form validation, and UI development.
Why These Tools Matter
These identifier tools serve critical functions in modern development:
- Data integrity – Valid IDs prevent data corruption and duplicate entries
- Testing efficiency – Generate realistic test data quickly
- Compliance – Proper ID formats meet industry standards
- Debugging – Validate IDs when troubleshooting systems
