The three ways to add someone on Snapchat

You can add someone on Snapchat by searching their username, scanning their Snapcode (a unique QR code), or letting the app suggest friends from your phone contacts. The method you choose affects what information Snapchat learns about your network — and what the other person learns about you.

When you search by username, only Snapchat's servers see the search. When you use the contacts method, Snapchat uploads your phone's contact list to match it against existing accounts. When you scan a Snapcode, you're just exchanging usernames in person, which tells Snapchat nothing new about your relationship.

After you add someone, they see your username, profile picture, and display name. They can message you, call you, or view your public story — depending on your privacy settings. You control whether they can see your location through Snap Map and whether they can contact you at all.

Key Takeaways

  • Searching by username or scanning a Snapcode tells Snapchat you know this person, which the company uses to build a map of your social network.
  • Using the "Add Friends" feature that syncs your phone contacts uploads your entire contact list to Snapchat's servers, even for people who don't use the app.
  • Once someone is added, they can see your username, profile picture, and story unless you change your privacy settings in the Friends section.
  • You can block someone after adding them, remove them from your friends list, or change what they can see about you without them knowing.
  • Snapchat keeps a record of your friend connections and uses this data for advertising and to suggest new friends to you and to others.

Adding someone by username or Snapcode

To add by username, open Snapchat and tap the add-friends icon (usually a person with a plus sign). Type their username and tap their profile. Hit "Add Friend" and they'll get a notification that you've sent a request. They have to accept before you're officially connected.

A Snapcode is a square QR-like image unique to each account. You can find yours in your profile settings. To add someone via Snapcode, tap the camera icon in the add-friends screen, point your phone at their Snapcode, and hold. Snapchat will open their profile so you can send the request. This method is faster in person and doesn't require either of you to remember a username.

Both methods tell Snapchat that you and this person know each other. The company uses this information to build what's called a "social graph" — a record of who is connected to whom. Snapchat uses this data to suggest new friends to you, to show you targeted ads, and to understand your interests based on your network.

Using the contacts sync feature and what it costs

Snapchat's "Add Friends" feature can scan your phone's contact list and show you which of those people have Snapchat accounts. To use it, go to your profile, tap "Add Friends," and select "Contacts." Snapchat will ask permission to access your phone's contacts. If you allow it, the app uploads your entire contact list — names, phone numbers, and email addresses — to Snapchat's servers.

This happens even for contacts who don't use Snapchat. Snapchat stores this data and uses it to match your contacts against other users' contact lists. The company says it deletes contact information after a certain period, but the exact timeline and what happens to the data during that window is not fully transparent in their public privacy policy.

If you've already used this feature, you can limit future uploads by going to Settings, then Permissions, and turning off Snapchat's access to your contacts. This won't delete data Snapchat already has, but it stops new uploads. Many privacy advocates recommend never using the contacts sync feature if you want to limit what Snapchat knows about your broader social network.

What happens after you add someone

Once someone accepts your friend request, they can see your username, profile picture, and display name by default. They can also view your public story — the photos and videos you post to your story that are visible to all your friends. They cannot see your location on Snap Map unless you specifically share it with them.

The other person can send you messages and call you through Snapchat. If you don't want this, you can block them (they won't know) or change your privacy settings so only certain friends can message you. Go to Settings, then Who Can, then Contact Me, and choose "Friends" or "My Friends" to limit who can reach out.

Snapchat also begins tracking your interaction with this person — whether you message them, how often, what you send, and when. This data is stored on Snapchat's servers and used to improve the app's recommendations and advertising.

Controlling what someone can see about you

After adding someone, you can change what they see without removing them as a friend. Open your profile, tap the three-line menu, and go to Friends. Find the person's name, tap and hold it, and select "View Friendship." From here you can block them, remove them, or change their privacy settings.

You can prevent someone from seeing your story by going to Settings, then Who Can, then View My Story. Choose "Custom" and toggle off the people you want to hide it from. You can also hide your location from specific people in Snap Map settings. These changes are silent — the other person won't get a notification that you've restricted them.

If you want to stop someone from contacting you without blocking them entirely, you can mute their messages. Go to the chat, swipe left on their name, and tap the speaker icon. They can still send messages, but you won't get notifications and the chat won't appear at the top of your list.

Why Snapchat wants to know who you're connected to

Every friend you add tells Snapchat something about your interests, your location (based on who you know), and your age group. The company uses this social graph to build a profile of you that's separate from what you post. This profile is used to show you ads from companies that want to reach people like you and your friends.

Snapchat also uses your friend list to suggest new people you might want to add. If you and another user have many mutual friends, Snapchat will suggest that you connect. This keeps people on the platform longer and gives Snapchat more data about your network.

Your friend list is also used by Snapchat's parent company, Meta (which owns Facebook and Instagram), if you've linked your accounts. Meta can see your Snapchat connections and use that information across its other platforms for advertising purposes.

Removing someone and what that does

If you want to stop being friends with someone, go to your Friends list, tap and hold their name, and select "Remove Friend." They won't get a notification, but they'll notice they can no longer see your story or message you (unless your privacy settings allow non-friends to contact you). If they try to view your profile, they'll see that you're not friends anymore.

Removing someone is different from blocking. When you block someone, they can't find you, message you, or see your story. When you remove them, they can still search for you and send a new friend request. Blocking is more complete but also more obvious if they try to contact you and get an error.

Snapchat keeps a record that you were once friends with this person. This historical data is used for analytics and may affect what ads you see or what friends are suggested to you in the future.

Frequently Asked Questions

Can someone tell if I've added them on Snapchat?

Yes, they get a notification that you've sent a friend request. If they accept, they'll see you in their friends list. If you remove them later, they won't get a notification, but they'll notice you're no longer friends if they try to view your story or message you.

What if I don't want Snapchat to upload my contacts?

Don't use the "Add Friends" feature that syncs your contacts. Instead, add people by username or Snapcode. If you've already uploaded your contacts, go to Settings, then Permissions, and turn off Snapchat's access to your phone's contacts. This stops future uploads but doesn't delete data already stored.

Can I add someone without them knowing?

No. When you send a friend request, they get a notification. They have to accept before you're officially friends. You can view someone's profile without adding them, but once you send the request, they know you're interested in connecting.

Does Snapchat share my friend list with other apps?

Snapchat shares data with its parent company Meta, which owns Facebook and Instagram. If you've linked your accounts, Meta can see your Snapchat connections. Third-party apps you've given permission to access Snapchat may also see limited friend information depending on what permissions you've granted.

What's the difference between removing and blocking someone?

Removing someone stops them from seeing your story and messaging you, but they can still search for you and send a new request. Blocking prevents them from finding you, messaging you, or seeing your profile at all. Blocking is more complete but they may notice if they try to contact you.
