Why short wins

Short domains, on demand.

Build invite-code-style domains from raw character sets — numbers, letters or alphanumeric — at any length, with every candidate checked for live availability.

Three character sets

Generate from numbers only, letters only, or a mix of both. Pure numeric for codes and shorteners, alphanumeric for punchy, pronounceable shorts.

Any length you set

Dial in 4-letter, 5-letter or longer builds for invite codes, referral links and URL shorteners — the generator constructs candidates to your exact length.

Live availability on every roll

Short names are scarce, so the filter does the heavy lifting: each candidate is checked against the registry, and only available domains are shown.

Built for codes and shorteners

The natural home for numeric and short domains — referral codes, promo links, QR landing pages and test environments where brevity beats branding.

Random, explained.

Yes. Every candidate the generator builds — whether numbers-only, letters-only or alphanumeric — is checked for live availability against the registry as it's created. Only available names appear in your results, so anything you see can be registered immediately through your preferred registrar.
Numeric and short alphanumeric domains shine where brevity matters: invite and referral codes, URL shorteners, promo links, QR landing pages and test environments. They're easy to type on mobile and memorable in the moment, even if they carry less brand meaning than a word-based name.
Yes — set the character length to 4, 5 or anything else and the generator builds candidates to that exact size. Fair warning: most 4-letter .coms are long taken, so the live availability filter is doing the real work here; it surfaces the short names that are actually still free.
Both. Choose numbers-only for pure numeric domains, letters-only for short alpha names, or alphanumeric to mix the two. You can also combine the character set with your length setting — for example, 5-character alphanumeric for invite-code-style domains. Every batch is availability-checked, so what you see is registerable.
Yes, completely free with no signup or account required. Generate as many batches as you like, re-roll freely, and register any name you love through your preferred registrar — Nomlen never charges for the generator or the availability checks. No paywall, no trial, no usage cap.
The random word generator builds brandable names from dictionary words — best for businesses and brands. This one builds from raw character sets, making it the right tool for short, punchy, often numeric domains like codes and shorteners. Use each where its strength lies.
