An availability checker answers one question: can this string be registered right now. That is a useful question and it is not the only one. Several kinds of name pass that test and still can't be used.
Reserved and blocked words
Every platform keeps a list of handles it won't hand out. The lists are not published, which is why you find out at the point of signup rather than before.
They typically cover the platform's own product names, words like admin, support, help and login, anything that could impersonate an official account, and a rotating set of terms tied to abuse. A handle can come back as free from every angle and still be refused when you press the button.
There is no way to test this from outside without attempting a registration, so we don't pretend otherwise. If a name matters to you, sign up for it rather than assuming it will still behave the way a check suggested.
Dormant accounts that aren't free
A handle held by an account with no posts, no photo and no activity since 2014 is still held. Every major platform has an inactivity policy on paper. In practice, released handles are rare and unpredictable, and none of the platforms will tell you when or whether a specific one will come back.
Reporting an inactive account to get its handle is not a route either. The policies exist for the platform's benefit, not yours, and the process is not a queue you can join.
Held deliberately
Some names are taken by people who took them precisely because someone would eventually want them. On domains this is decades old and well understood. On handles it is quieter but real, particularly for short names and common words.
Buying from a holder is a normal transaction on domains, with escrow services built for it. On social handles it is murkier: most platforms' terms prohibit selling accounts, so a purchase can end with the handle reclaimed and both parties penalised. Weigh that before money moves.
Free everywhere, and still not yours
This is the big one, and it is the reason we are careful about what this site claims.
A name being technically registrable tells you nothing about whether someone else already has rights in it. A trading name, a registered trademark, or an established business in your sector can all exist without occupying the handle you are looking at. A checker cannot see any of that.
BRANDZLI reports technical availability only. It is not trademark clearance and it is not legal advice. If you are about to spend real money on a name — a rebrand, packaging, a product launch — the search that matters is a trademark search in the classes and countries you'll trade in, and that is work for someone qualified to do it.
Names that will fight you later
Some names are available for a reason. Worth noticing before you commit:
- A name one letter from a much bigger company's. You will spend forever being mistaken for them, and they may take an interest in that.
- A word that means something unfortunate in another language, if you plan to sell in one.
- Something that reads badly when the spaces come out — the classic handle failure, and it has genuinely ended real brands.
- A word with an existing meaning so strong that search results will never be yours.
How to read our results with this in mind
Available means the platform's public signals say the handle can be taken. Taken means they say it can't. Not confirmed means we couldn't get a trustworthy answer and we would rather say so than guess — several platforms deliberately make anonymous checking unreliable, and we won't turn that into a green light.
None of the three is a statement about your right to use the name. That question sits outside anything a checker can see.
