Discord Username Checker · Bulk, CSV & Sheets [No Login]

Discord Username Checker

Find out which Discord usernames are free to claim, in bulk. Paste a list or link a CSV, TXT or Google Sheet, and get one row per name: available, taken or invalid, with Discord's own reason for every refused name and the exact time it was checked.

Why Use This Scraper?

• Bulk in one run. Thousands of names per run, from a pasted list, a CSV, a TXT, a JSON list or a Google Sheet link.
• Discord's own verdict. Every answer comes from Discord's sign-up check, so "available" means Discord would accept the name right now.
• Reasons, not just "no". Refused names come back with Discord's reason code and message: too short or long, a character Discord does not allow, repeated dots, or a word Discord reserves (discord, nitro, clyde and others).
• A free alternative for every miss. Turn on suggestions and each taken or invalid name gets the name Discord itself offers in its place.
• Only answers are billed. A name Discord did not answer comes back with status unknown and costs nothing. Names that break Discord's basic rules are answered on the spot and cost nothing either.
• No account, no token, no setup. Nothing to log in to and nothing to configure besides the list.

Overview

Discord moved every account to unique usernames in 2023, and good names went fast. This actor tells you which of your candidate names can still be registered, so you can pick a handle for yourself, a brand, a bot or a community before someone else does.

Every unique name on your list becomes one dataset row. The row says whether Discord would accept the name today, why it would refuse it, how long the name is, where it sat in your list, and when it was checked. Rows are written as answers arrive, so a large list fills the dataset steadily and you can sort by position to get your original order back.

The actor checks names, nothing else. It does not look up who owns a taken name, and it never registers or reserves anything.

Supported Inputs

Name forms

You enter	Checked as	Note
coolname	coolname	Plain names
CoolName	coolname	Upper case is folded to lower case, as Discord does
@coolname	coolname	Mentions
coolname#1234	coolname	Pre-2023 tags; the number is not part of a username
alpha, beta; gamma	alpha, beta, gamma	Commas and semicolons separate names in the list field
cool gamer	cool gamer	Stays one entry and comes back invalid (spaces are not allowed), with a suggested valid name if suggestions are on

Repeated names (after folding case and removing @ and tags) are checked once.

File links

File	How names are read
TXT	One name per line
CSV or TSV with a header	The column named username, user name, name, handle or tag (any case)
CSV without a matching header	The first column of each line
A single comma-separated line	Every value on the line
JSON	An array of strings, or of objects with a username, name or handle field

Share links work as they are: a Google Sheet shared as "anyone with the link" (the tab in the link is the one read), a GitHub file page, a Pastebin page and a Dropbox share link are turned into their download form for you.

Unsupported inputs

• Discord user IDs and profile links (discord.com/users/123...). The actor checks names, not accounts.
• Server names, server invites and channel names. For servers, see the Discord Server Scraper below.
• Private files that need a login to download. Share the file publicly or paste the names.

Use Cases

Who	What they do with it
Gamers and streamers	Shortlist a handle across dozens of spellings and grab the first free one
Brands and agencies	Check brand, product and campaign names before a launch, and spot names that are already taken
Handle hunters	Scan generated lists of short or dictionary names for free ones
Community and bot builders	Make sure the bot, mod and staff names you plan to use can be registered
Developers	Add an availability check to a sign-up flow, a name generator or a Discord tool through the API
Researchers	Measure how crowded the namespace is for a word list or a naming pattern

How It Works

1. Give it names. Paste them into "Usernames", link one or more files, or both.
2. Names are cleaned. Case is folded, @ and old #1234 tags are dropped, repeats are removed.
3. Discord's basic rules are applied first. Names Discord would refuse for length, characters or repeated dots are marked invalid straight away, free of charge.
4. Every other name is checked with Discord. The answer is available, taken, or invalid with Discord's reason (reserved words are Discord's list, so those are always asked).
5. One row per name lands in the dataset, with the optional suggested free name and the check time. Export as JSON, CSV, Excel or through the API.

Input Configuration

Input fields

Field	Type	Default	What it does
usernames	array of strings	-	Names to check, one per line. Commas and semicolons also separate names. Accepts name, @name, name#1234.
usernameFileUrls	array of strings	-	Links to TXT, CSV, TSV or JSON files with more names, including Google Sheets, GitHub, Pastebin and Dropbox share links.
suggestAlternatives	boolean	false	For each taken or invalid name, add the name Discord offers in its place at sign-up.
maxUsernames	integer	all	Stop after this many unique names.

At least one name, from the list or a file, is needed.

Example: a short list

{
    "usernames": ["jason", "gamer", "pixel.fox.2026"]
}

Example: a Google Sheet plus suggestions

{
    "usernameFileUrls": ["https://docs.google.com/spreadsheets/d/YOUR_SHEET_ID/edit#gid=0"],
    "suggestAlternatives": true
}

Example: the first 500 names of a large file

{
    "usernameFileUrls": ["https://example.com/names.txt"],
    "maxUsernames": 500
}

Output Overview

Each row is one unique name. status is the field to filter on:

• available: Discord would accept the name right now.
• taken: someone already has it.
• invalid: Discord would refuse it. reasonCode and reason say why.
• unknown: Discord gave no answer for this name during the run. The row is free; run the name again later.

available repeats the verdict as true / false (null for unknown), which is handy for spreadsheet filters.

FAQ

How accurate is "available"?

It is Discord's own answer at checkedAt. Names change hands all the time, so a name that is free now can be taken minutes later. Claim the ones you want soon after the run.

Why is a name marked invalid when nobody has it?

Discord refuses some names whoever asks: fewer than 2 or more than 32 characters, anything other than a-z, 0-9, _ and ., two dots in a row, or a reserved word such as discord, nitro, clyde, wumpus, hypesquad or snowsgiving. The row's reason says which rule applies.

What does unknown mean, and am I charged for it?

Discord did not give an answer for that name during the run, after several tries. It is rare (none in test runs of 200 and 545 names), the row is free, and running the name again later normally answers it.

Why is suggestedUsername empty for some taken names?

Discord sometimes has no offer, mostly for very short, common names such as john or mike. The field is then empty, as it is when suggestions are off. Discord's offers change from one request to the next, so a later run may fill it.

Is a suggested name guaranteed to be free?

It is the name Discord itself offers at sign-up for that input, so it was free when offered. It is not checked a second time; run it through the checker if you want a separate row for it.

Can I check names with upper-case letters?

Yes. Discord folds usernames to lower case, so CoolName and coolname are the same name. The row shows both: input as you typed it and username as Discord stores it.

Does it work with old name#1234 tags?

Yes. The #1234 part is dropped and the name is checked as a new-style username.

How many names can I check in one run?

There is no fixed cap on paid plans. Test runs on Apify checked 200 names in 17 seconds and about 11 names a second on a 10,000-word list, so 10,000 names take roughly 15 minutes. Free Apify plans check the first 100 names per run.

What happens when my spending limit is reached?

The run stops starting new checks, keeps every row it already wrote, and the log says how many names were left unchecked. Unchecked names cost nothing.

Can it tell me who owns a taken name?

No. The actor reports whether a name can be registered. It does not look up accounts or profiles.

How am I billed?

One event per name Discord answered: available, taken, or invalid with Discord's reason. Names that break Discord's basic length, character and dot rules are answered without asking Discord and are free. unknown rows are free. Suggestions add no charge.
