32665 is a short code Facebook uses for texts in the US, including login codes and alerts. The number spells FBOOK on a phone keypad.
Short codes are 5 or 6 digit numbers that companies lease for bulk messages in a country. Outside the US, Facebook uses other numbers, so the sender you see depends on where you are and on your carrier.
Change your notification settings in Facebook, or remove your phone number in Accounts Center › Personal details › Contact info. Replying STOP to a short code usually stops non-essential messages, but keep a sign-in method that still works first.
The sender ID can be imitated in some cases, so judge the content, not just the number. Facebook codes never ask you to tap a link to keep your account, and no one at Facebook will ask you for a code.
Facebook can send alerts as texts or as app notifications. App notifications are free, faster and do not depend on your carrier, so many people turn text alerts off and keep only security texts. Check Settings › Notifications in the app to choose which ones still come by SMS.
