What linking a sub means in Discord
Linking a sub in Discord means mentioning another Discord server (called a "server" or "guild") inside a message so that people can click it and join. When you type a server invite link into chat, Discord turns it into a clickable button or text that takes people directly to that server. This is different from linking a regular website — Discord recognizes its own invite codes and formats them specially.
The most common reason to link a sub is to direct members to a related community, a backup server, or a sister community. You can share an invite link in any channel where you have permission to post messages, and anyone who sees it can click through if the invite is still active.
Key Takeaways
- You need an active invite link from the server you want to share, which the server owner or a moderator must generate first.
- Paste the full invite link (starting with discord.gg or discord.com/invite) directly into your message and Discord will format it automatically.
- The person who created the invite link controls whether it expires, how many people can use it, and whether it's one-time only.
- Some servers block invite links in their channels, so check the channel rules before posting one.
Getting an invite link from the server you want to share
Before you can link a sub, you need the actual invite link. If you're the owner or moderator of the server you want to share, you create this yourself. If you're a regular member, you need to ask the owner or a moderator to generate one for you.
To create an invite link if you have permission: Open the server, click the server name at the top left, select "Invite People," and Discord will show you an invite link. You can customize it — set an expiration date, limit how many people can use it, or make it one-time only. Copy the link (it looks like discord.gg/abc123def or discord.com/invite/abc123def) and you're ready to share it.
Pasting the link into chat
Once you have the invite link, paste it directly into the message box in any channel where you can post. You don't need to do anything special — just paste the full link and hit send. Discord automatically recognizes it and turns it into a formatted invite button or preview that shows the server name and icon.
The link must be complete and start with either discord.gg/ or discord.com/invite/ for Discord to recognize it. If you paste only part of the link or modify it, Discord won't format it as a clickable invite. Type or paste the entire link exactly as it was given to you.
What happens after you post the link
Once the link is in chat, anyone who can see that message can click it. Discord will show them a preview of the server (the name, icon, and number of members) and a button to join. They don't need to be invited by you personally — the link itself is the invitation.
The person who created the invite link controls what happens next. If they set an expiration date, the link stops working after that time. If they set a member limit, the link stops working once that many people have joined. If they made it a one-time link, it works only for the first person who clicks it. After that, the link is dead and no one else can use it.
When servers block invite links
Some servers have rules that prevent members from posting invite links to other servers in their channels. This is a moderation choice — the server owner or moderators set it up to keep the focus on their own community. If you try to post an invite link in a channel with this rule, Discord will either delete your message or prevent you from sending it in the first place.
If you need to share a server invite and the channel blocks it, ask a moderator if there's a specific channel where links are allowed, or send the link as a direct message instead. Direct messages between users are not subject to channel rules, so you can always share an invite that way.
Troubleshooting a link that doesn't work
If someone clicks your link and gets an error, the most common reason is that the link has expired. Check with whoever created it — they may need to generate a new one. Another reason is that the server reached its member limit if one was set. A third reason is that the person clicking the link was already banned from that server, which prevents them from joining even with a valid link.
If the link looks broken in chat (it's not formatted as a clickable button), you may have pasted it incorrectly or it got cut off. Copy and paste it again, making sure the entire link is included and nothing is missing. If Discord still doesn't recognize it, ask the server owner to generate a fresh invite link and try again.
Frequently Asked Questions
Can I see who joined through my invite link?
If you created the invite link, you can see how many people have used it by going back to the invite settings. However, Discord doesn't show you the names of individual people who joined through that specific link — only the total count. You can see who joined the server overall, but not which link they used.
What's the difference between a permanent link and one that expires?
A permanent link never stops working and can be used by unlimited people. An expiring link works only until the date you set, then becomes invalid. One-time links work only for the first person who clicks them. Choose based on what you need — permanent for ongoing recruitment, expiring to limit access to a specific event or period.
Can I change an invite link after I've shared it?
You can't edit a link that's already been created, but you can revoke it (make it stop working) and create a new one. If you revoke a link, anyone who tries to use it will get an error. This is useful if you shared a link by mistake or want to stop people from joining through that specific invite.
Do I need permission to post invite links in a channel?
You need general permission to post messages in that channel. Some channels have additional rules that block invite links specifically, even if you can post other messages. Check the channel description or ask a moderator if you're unsure whether links are allowed.
What happens if the server I'm linking to gets deleted?
If the server is deleted, the invite link becomes invalid immediately. Anyone who clicks it will see an error saying the server doesn't exist. There's no way to recover the link or the server — deletion is permanent.
