How does this domain checker work?
Type a name and Postlia checks the .com against the domain registry (RDAP) in real time to see whether it's already registered. If the registry is unreachable, we tell you and link you out to confirm — we never guess.
Which domain extension does it check?
This tool checks the .com — the extension most people want for a brand or personal site. Enter just the name (or paste a full URL and we'll strip the scheme, www, and any typed extension before checking .com).
Is an available domain guaranteed?
Availability is a point-in-time signal and can change at any moment as others register names. Always confirm and complete registration with a registrar to lock it in.
What makes a good domain name?
Short, easy to spell, easy to say out loud, and closely tied to your brand or handle. Matching your social usernames to your domain makes you easier to find everywhere.
