Availability checking

Domain checker: what to verify before you buy

Availability is only one part of a domain decision. A good checker helps you compare names in batches, avoid wasted provider calls, and understand when a result still needs manual verification before money, branding, or launch plans depend on it.

Search workflow Registrar decision path

Availability states

Available

The provider or preview source says the domain can be checked for registration. Still verify price, renewal, premium status, and restrictions at checkout.

Taken

The domain appears registered or unavailable. Test nearby variants, a cleaner modifier, or a different TLD instead of adding random hyphens.

Unknown

The checker cannot make a confident call. Treat this as a prompt to verify with a registrar or authoritative provider.

Provider confirmation

A checker result is informational. Final registration availability, premium status, pricing, renewal terms, and restrictions are confirmed by the registrar or provider.

Why batch checks matter

Domain search tools can waste provider quota if they check every keystroke. RunNames is built around submitted searches, capped TLD selections, result limits, caching, and filters that run locally after the batch returns. That keeps the search experience useful without encouraging throwaway mass checks.

Use the domain search workflow to generate a small set first, then use checker results to decide which finalists deserve manual review.

What to verify outside the checker

How to handle an available result

  1. Open the registrar checkout only after the name passes the readability and fit checks.
  2. Confirm the first-year price, renewal price, privacy options, and transfer rules.
  3. Search for similar businesses before using the name in logos, packaging, ads, or email templates.
  4. Register only the names you have a real plan to use, redirect, or protect.

Check the shortlist, not just one name

Generate several alternatives, filter them, then verify the finalists with a registrar. Future registrar CTAs may be paid links and should carry clear disclosure plus sponsored nofollow attributes.
