To friend FlexCodesUGCS on Roblox, search for that username, open the profile, and tap Add Friend or Add Connection if the option appears. Roblox’s help page says to find the person by typing the username in the top search bar and switching the search category to People before sending the request.

Fast steps

  1. Open Roblox and log in.
  2. Use the search bar at the top.
  3. Type FlexCodesUGCS exactly.
  4. Change the search to People if needed.
  5. Open the profile.
  6. Click Add Friend / Add Connection.

If it does not work

  • The account may have privacy settings that block friend requests.
  • You may already be connected, so the button may not show.
  • The username may be spelled differently, so double-check capitalization and numbers.

On mobile

The same idea works in the app: search for the username, open the profile, then tap the add-friend icon or button. A Roblox tutorial also notes that the request usually shows as pending after you send it.

If you want to join them in a game instead of friending them, Roblox also supports Join Experience when that player allows it.

TL;DR: search FlexCodesUGCS under People , open the profile, and hit Add Friend if the button is there.
