Detailed instructions

1. Set the Digits selector to 3 (CVV/CVC format) or 4 (Amex CID format) depending on your testing needs.
2. Enter the number of codes you want in the Count field — use a higher number to seed a database or CSV file.
3. Click Generate to produce a fresh batch of random numeric codes instantly.
4. Copy the output list and paste it directly into your test harness, spreadsheet, or design file.

Use Cases

• •Seeding a Stripe sandbox test run with 50 fake CVV values paired with documented test card numbers
• •Populating Figma payment form components with realistic-looking CVC and CID fields
• •Stress-testing input validation logic for 3- and 4-digit numeric fields in a Jest or Cypress test suite
• •Generating bulk OTP mockup values to demonstrate two-factor authentication UI flow in a prototype
• •Creating a CSV of sample card security codes to train data-entry staff without using real cardholder data

Tips

• →For Stripe sandbox tests, pair 3-digit codes from this tool with the test card number 4242 4242 4242 4242 and any future expiry.
• →When building input validation, generate codes that start with 0 (like 007) to confirm your form handles leading zeros correctly.
• →Generate a mix of 3-digit and 4-digit codes in separate runs if your checkout form must support both Visa and Amex card types simultaneously.
• →Paste a large batch into a spreadsheet column and use it alongside generated names and expiry dates to build a complete fake card dataset for load testing.
• →If your test suite requires unique codes only, generate more than you need then remove duplicates — the 3-digit range has just 1,000 possible values, so overlap is common above ~100 codes.
