🪪 National ID Generator
Generate national identification numbers with built-in checksum logic for the US, UK, India, Canada, and Spain.
National ID Generator
Create dummy national identifiers that satisfy length, prefix, and checksum rules. Perfect for QA environments, form validation, and prototyping workflows that rely on structured ID numbers.
873-37-9825Generates US Social Security Numbers with valid area, group, and serial ranges. Area numbers avoid 000, 666, and 900–999.
SSNs are formatted with dashes. Use only for testing systems that require a valid length and structure.
How to use this tool
- Choose a country profile to load the correct format and checksum rules.
- Generate as many sample IDs as needed, copying them without spaces for system tests.
- Swap between countries to confirm your validation logic supports multiple formats.
QA playbook
- Seed staging databases with realistic identifiers that won’t collide with production data.
- Automate regression suites by calling the generator before submitting signup forms.
- Stress-test masking and redaction features to ensure formatted IDs stay legible.
Validation insights
- SSN generation enforces disallowed area codes like 000 and 666 to mimic SSA rules.
- NINO prefixes skip restricted letters per HMRC guidance—useful for front-end autocomplete.
- Checksums rely on the official Luhn or Verhoeff algorithms, catching logic bugs early.
FAQ
- Are these real identities?
- No. Outputs are synthetic and should only be used in development or demo environments.
- Can I add my own country format?
- Clone an existing generator in code and adjust the pattern or checksum to match your requirements.
- Why are some characters excluded?
- Many jurisdictions reserve or forbid certain prefixes. The generator mirrors those official constraints.
