Where to find your blocked numbers in Zoom

Your blocked contacts list in Zoom lives in your account settings, not in the main meeting interface. Open Zoom on your computer or phone, sign in, and go to Settings (the gear icon). From there, select Privacy or Contacts depending on your device — the exact name varies between desktop and mobile. You will see a section labeled Blocked Contacts or Blocked Users that shows everyone you have blocked.

On a computer, the path is usually Settings > Privacy > Blocked Contacts. On an iPhone or Android phone, it is Settings > Contacts > Blocked Contacts. If you do not see this option, your account may not have blocking enabled, or you may be using an older version of the Zoom app — updating to the latest version usually fixes this.

Key Takeaways

  • Blocked contacts appear in your account Settings under Privacy or Contacts, depending on whether you use a computer or phone.
  • Blocking someone in Zoom prevents them from calling you, messaging you, or seeing your online status, but does not prevent them from joining a meeting you host if they have the link.
  • You can unblock a contact at any time by finding their name in the blocked list and selecting the unblock option.
  • Blocking is personal to your account — it does not affect other users or prevent the blocked person from using Zoom.

How blocking works in Zoom

When you block someone in Zoom, that person cannot call you directly, send you messages, or see whether you are online. However, blocking does not prevent them from joining a meeting you host if they already have the meeting link or ID. Blocking only stops direct contact — it does not remove them from shared meetings or group chats they were already part of before the block.

The blocked person will not receive a notification that you have blocked them, but they may notice they cannot reach you by phone or chat. If they try to call you, the call will fail silently on their end. This is useful if you want to avoid unwanted contact without creating conflict.

Unblocking a contact

To unblock someone, return to your blocked contacts list in Settings. Find the person's name and select the option to unblock — usually a button or menu option next to their name. Once you unblock them, they can call and message you again immediately. You do not need to confirm the unblock or send them a notification.

Unblocking is reversible, so if you block the same person again later, you can do so without any penalty or special steps. Your block history is not visible to anyone else.

Blocking someone you have not contacted before

You can only block contacts who are already in your Zoom contact list or who have contacted you. You cannot block a random phone number or email address that has never reached out to you. If someone is harassing you through Zoom and they are not in your contacts, you can report them to Zoom support instead — go to Settings > Help > Contact Zoom Support and describe the issue.

If a stranger joins one of your meetings and disrupts it, you can remove them from that meeting by right-clicking their name and selecting Remove. You can also lock your meeting so no one else can join once it has started.

Differences between blocking and muting

Blocking and muting are not the same thing. Muting someone means you will not hear their audio during a meeting — they can still speak, but you cannot hear them. Blocking prevents them from contacting you at all outside of meetings. If you are in a meeting with someone and want to silence them, mute their audio. If you want to stop them from calling or messaging you entirely, block them.

You can also mute notifications from a specific contact without blocking them. This stops you from receiving alerts when they message or call, but they can still reach you if they try.

What happens to group chats when you block someone

If you block someone who is in a group chat with you, they will remain in that chat and can still see messages and participate. Blocking only prevents one-on-one contact. If you want to remove someone from a group chat entirely, you must leave the chat or ask the chat owner to remove them — blocking alone will not do this.

If a blocked person sends a message in a group chat, you will still see it. Blocking does not hide their messages in shared spaces, only prevents them from reaching you privately.

Frequently Asked Questions

Can someone tell if I have blocked them?

No, Zoom does not notify the blocked person that you have blocked them. However, if they try to call you repeatedly and the calls keep failing, they may suspect you have blocked them. There is no way for them to see your blocked contacts list or confirm the block.

Will blocking someone remove them from my meetings?

No. Blocking prevents direct contact only. If a blocked person has the meeting link or ID, they can still join your meeting. If you do not want them in a specific meeting, remove them manually during the meeting or lock the meeting so no one else can join.

Can I block someone on Zoom if they are not in my contacts?

No. You can only block people who have already contacted you or who are in your contact list. If a stranger is harassing you, report them to Zoom support instead. You can also remove them from your meetings if they join.

Does blocking someone on Zoom affect other apps or services?

No. Blocking in Zoom only affects Zoom. It does not block them on email, phone, text, or any other platform. If you want to block someone across multiple services, you will need to block them separately in each one.

Can I see who I have blocked on my phone and computer?

Yes. Your blocked contacts list syncs across all your devices. If you block someone on your computer, they will also be blocked on your phone, and vice versa. The list appears in Settings on both platforms.
