Serial Number Generator
Generate unique serial numbers for products, equipment and assets. Supports custom prefixes for product line identification. Everything is generated in your browser using the Web Crypto API (crypto.getRandomValues), so nothing you create is sent to a server.
Frequently Asked Questions
Should serial numbers be sequential or random?
Sequential serials are easier to track and audit but reveal production volumes. Random serials hide this information and are harder to forge. Use our Sequential Generator for ordered serial numbers.
How do I add product line prefixes to serial numbers?
Use the Prefix field. For example, prefix LAPTOP- for laptops and PHONE- for phones so support teams can immediately identify the product from the serial number alone.
Can I use serial numbers for warranty tracking?
Yes — export serial numbers to CSV and import them into your warranty management system. Record the manufacture date alongside each serial for warranty period calculations.
