Random Code Generator

Random Code Generator: a free, instant online tool for random code — no sign-up, no limits, right in your browser. Fast, accurate, and easy to use.

Need a quick random code for a giveaway, a test account, a coupon, or a placeholder ID? The Random Code Generator creates unique alphanumeric codes instantly, right in your browser, with the length and format you choose.

What it's used for

Promo and discount codes, invite codes, test data for development, raffle and giveaway entries, temporary access codes, and any situation where you need a batch of unique-looking identifiers fast.

Format options

Choose the length and whether to include letters, numbers, or both, and generate as many codes as you need in one go — useful for bulk-generating giveaway codes or seed data for testing.

A quick note on real security use

This tool is built for speed and convenience, not cryptographic security — for anything protecting real accounts or payments (like password reset tokens), use a proper cryptographically secure generator on the backend, not a client-side tool.

Frequently asked questions

Are the codes guaranteed unique?

Each generation run produces randomized codes with a very low collision chance at typical lengths, but for large batches where uniqueness is critical, deduplicate the output yourself before use.

Can I set a custom length?

Yes — pick the length and character set that fits your use case, from short 4-character codes to longer secure-looking strings.

Is this safe to use for real password resets?

No — use this for placeholders, test data, and promo codes, not for anything securing real user accounts.
