Gmail Availability Checker
A Gmail availability checker answers one narrow question: is this Gmail name still free, or has somebody already taken it? Type the address you have in mind and the answer comes back in a second or two. If the result is Unregistered, no Google account exists on that address, and in almost every case the name is still open. If the result is Live, Disabled or Verify, an account already sits on that name and you will need a different one.
This page explains how the check works and the few cases where an address that looks free still cannot be registered. Those exceptions are the part most guides leave out.
How to check if a Gmail address is available
- Open the checker. It is on the home page. A free account is needed to run a check, which is a username and a password, with no card.
- Type the whole address. Write it as
name@gmail.com, not just the username on its own. - Leave Fast Check switched off. Normal mode is the one that separates Unregistered from the other results, and that distinction is the entire value of the answer.
- Press Check and read the status in the results row.
- Read it this way: Unregistered means nobody holds the name. Anything else means somebody does.
Nothing is sent to the address during the check, so nobody is notified that you looked at their name, and no message lands in any mailbox. The tool asks Google about the address and reports what Google says.
Available to register is not the same as live and deliverable
These are two different questions, and mixing them up is the single most common mistake people make with an availability check.
- Available to register means no account exists on the address, so the name is free for a new signup.
- Live and deliverable means an account does exist and its mailbox accepts mail today.
They are opposites, and an address cannot be both. A name you can register receives no mail, because there is no mailbox behind it yet. The same check answers both questions, and only the result you are hoping for changes.
| Result | Does an account exist? | Can you register this name? |
|---|---|---|
| Unregistered | No account was found | Almost always yes |
| Live | Yes, active, accepts mail | No |
| Disabled | Yes, but Google has suspended it | No |
| Verify | Yes, waiting on phone verification | No |
| Deleted (Premium option) | It existed and was removed, and Google still holds the name | No, the name is retired |
| Die (Fast Check only) | Not answered | Cannot tell, run it again in Normal mode |
| Error | Not answered this time | Check again before deciding |
That is why Fast Check is the wrong mode here. It folds Disabled, Verify and Unregistered into one result called Die, and a suspended account is very much taken, so Die cannot tell you whether a name is free. Keep Fast Check off.
Where the answer is reliable, and where it is not
There are four situations in which a name reads as Unregistered and still cannot be claimed. Knowing them is more useful than a confident answer that fails at the signup form.
Google keeps some names permanently reserved
Every mail system holds back a short list of names. Addresses such as abuse, postmaster and support, and names that look too much like a Google service, are never handed out. No account sits on them, so a check reports Unregistered, yet the signup form will refuse them.
A deleted account does not release the name
This one surprises people. When somebody deletes a Google account, the address is retired rather than recycled. Nobody can register it again afterwards, not even the person who owned it. A plain check finds no account and reports Unregistered, which is technically correct and practically misleading. If this matters to you, the Check Deleted option, which is part of Premium, reports those names separately as Deleted so you do not mistake a retired name for a free one.
Dots do not create a new name
Gmail ignores full stops in the username. john.smith@gmail.com, j.o.h.n.smith@gmail.com and johnsmith@gmail.com are the same mailbox. So if the plain form is taken, no dotted variant of it is free, and a check on any of them returns the same status. The same goes for anything after a plus sign, which Gmail treats as a label on the same address, and for googlemail.com, which is another spelling of the same domain.
Name rules can make a name unusable even when it is empty
A Gmail username has to be between 6 and 30 characters and may contain only letters, numbers and full stops. Hyphens, underscores and other symbols are not allowed, and the name cannot start or end with a full stop. A name that breaks those rules comes back as Unregistered, because no account could ever exist on it, but it cannot be registered either.
So the honest reading is this. Unregistered means nobody is using the name today, which rules out the usual reason a signup fails. The last word belongs to the Google signup form, and the checker is there to save you from typing twenty candidate names into it one at a time.
Google Workspace addresses on a custom domain
An address such as you@yourcompany.com follows different rules. Availability is decided by the administrator of that domain, not by Google, so a name that is free on one company domain may be taken on another. The checker can report whether a Workspace address accepts mail, which tells you a mailbox exists, but only a domain administrator can create a new one. Workspace support is a Premium feature.
Checking a list of Gmail names at once
Picking a name is rarely one guess. Most people write down fifteen or twenty variants, and checking them one by one is slow. Paste the whole list into the bulk Gmail checker instead, one address per line, run it once, then filter the table down to Unregistered. What remains is your shortlist.
A free account checks up to 500 addresses per run, far more than a naming session needs. Premium raises that to 50,000 per run, which suits people cleaning mailing lists. Results can be copied by status or exported as TXT or CSV.
Why people check Gmail availability
- Choosing a new address. Personal, or a clean name for a brand or a project, without trial and error inside the signup form.
- Protecting a name. Checking whether the obvious variants of a business name are still open before somebody else registers them.
- Cleaning a mailing list. An Unregistered result on a list you already own usually means a typo or an address that never existed. Removing those before a send protects your sender reputation.
- Checking a contact. Confirming that an address somebody gave you is a real, working account rather than a slip of the keyboard.
Whichever brought you here, remember that a status reflects what Google reports at the moment of the check, not a permanent fact. Accounts are created, suspended and deleted every day, so a name you checked last month is worth checking again.
Gmail availability checker FAQ
How do I check if a Gmail address is available?
Type the full address into the checker on the home page and press Check, with Fast Check switched off. A result of Unregistered means no account exists on that name, so it is almost certainly free. Live, Disabled and Verify all mean the name is already taken.
Can I check whether a Gmail username is available without opening the signup form?
Yes, and that is the point of this tool. The signup form only tells you a name is taken after you have filled in your details, and it gives you no way to test a list of candidates.
Is the Gmail availability checker free?
Yes. You need a free account, a username and a password with no card, and after that there is no charge per address up to 500 per run. Premium changes the per-run limit, the speed and API access, not the accuracy of a single answer.
Does Unregistered mean the name is definitely free?
It means no account was found on that address at the moment of the check, which is the reason most signups fail. Four exceptions remain: names Google reserves permanently, names retired after an account was deleted, names that differ from a taken one only by full stops, and names that break the 6 to 30 character rule. Outside those, Unregistered means free.
If a Gmail account was deleted, can I take the address?
No. Google retires the address rather than releasing it, and nobody can register it again, including the original owner. A basic check shows Unregistered for these because no account is there any more. The Check Deleted option, which needs Premium, flags them separately as Deleted.
Does adding a dot make a Gmail name different?
No. Gmail ignores full stops inside the username, so a dotted version of a taken name is the same mailbox and is equally unavailable. Anything after a plus sign is ignored in the same way, and googlemail.com is simply another spelling of gmail.com.
Can I check a Gmail address without sending an email to it?
Yes. No message is sent at any point. The check asks Google about the address and reports the answer, so the person behind an existing account is never notified that somebody looked.
Can I check availability for a Google Workspace address on a custom domain?
You can check whether such an address currently accepts mail, which tells you whether a mailbox exists. You cannot register a new one unless you administer that domain, because availability on a custom domain is controlled by its administrator and not by Google. Workspace domain checks are a Premium feature.
