Reference/Order ID Generator - Configurable Unique IDs
Generate configurable reference numbers, order IDs, token numbers, or serial numbers with a custom prefix, length, character set, and optional embedded date.

How to Use the Reference/Order ID Generator
Set an optional prefix, choose how long the random portion should be, pick a character set (Numeric Only or Alphanumeric), and optionally toggle in today's date as a component. Enter how many IDs you need at once and click Generate. This one flexible, configurable tool covers what would otherwise be several near-identical generators — token numbers, serial numbers, reference numbers, and order IDs are all really the same underlying pattern with different formatting preferences.
Example
With prefix "ORD", date embedding on, an 8-character alphanumeric random portion, and a count of 3, the tool might generate IDs like "ORD-20260905-7K3M9QXZ" — a readable, sortable order ID format combining a prefix, date, and unique random suffix.
Common Use Cases
- Generating order IDs or reference numbers for an e-commerce or invoicing system mockup.
- Creating unique serial numbers for a batch of test records or sample data.
- Producing token or ticket numbers that combine a readable prefix with a random unique suffix.
FAQs
- How random is the generated portion? It uses the Web Crypto API's crypto.getRandomValues(), giving cryptographically strong randomness rather than a predictable pseudo-random sequence.
- Could two generated IDs ever collide? It's possible but extremely unlikely with a reasonably long random portion (8+ characters) — for guaranteed uniqueness in a production system, still check new IDs against your existing records.
- What's the difference between this and a UUID generator? A UUID follows a strict, universally standardized 36-character format. This tool instead lets you fully customize the prefix, length, character set, and date component to match your own business ID conventions.
