Continuity mistake: When Jim is talking to his dad at the start about being embarrassed, his arm moves depending on the shot. (00:03:20)
Visible crew/equipment: When the guys arrive at the beach house, there is a shot of the pick up going by the house. If you look, you can see the film crew reflected in the paintwork of the blue pickup. (00:23:50)
Continuity mistake: At the start of the movie, where Jim's father comes into the dorm room after that guy unlocks the door for him, he comes in, and drops the six-back of beer then sees what Jim is doing, at an angle. When it drops to the floor, it is standing. Wouldn't it be on its side? (00:03:00)

Continuity mistake: In the scene when the guys are painting their first house, you see Stifler talking to Finch, and Stifler is holding a bottle by the cap. In the very next shot, he is holding it by the bottle itself. You never see him change his grip on the bottle. (00:25:20)
Continuity mistake: In the scene where Jim meets Michelle at band camp and he guesses that a bear came, when she is saying "It's like you can read my mind," there is a side shot of her, and you can see that the hair down her right side is one big group followed by a few obvious strands just in front. When the shot changes back to a front view of Michelle there are no extra strands visible. (00:27:40)
Continuity mistake: When Michelle gets into her car after the splitting up scene she's not wearing her seatbelt then it's cuts to a different angle and she is. (01:20:20)

The top photo, Stifler's mom is not wearing the graduation cap, the bottom one, she is.

Continuity mistake: In the scene where Jim, Oz and Finch are sitting in front of Dog Years after the call from Nadia, you can see some people in the back. When Kevin shows up the people disappear. The camera moves away for a moment and after it comes back, the people have reappeared. (00:21:35)
Factual error: Jim looks at a postcard sent to him from Nadia and it's addressed to 7 Beach Way, Grand Harbor, MI 49456. There is no Grand Harbor in Michigan. 49456 is a real ZIP (postal) code for Spring Lake, Michigan. (01:00:40)
Continuity mistake: In one of the first scenes of the movie when Stifler is talking to Oz in a classroom, you can see clearly that Stifler has a cold sore on his left side of the bottom lip. The camera changes to Oz and later on when shows Stifler again the sore is gone. (00:05:10)

Factual error: The movie is supposed to take place in Michigan, but you can often see the southern CA mountains in the background in the beach scenes. There are no mountains in Michigan that look like those.
Continuity mistake: In the scene where Jim makes a fool of himself by trying to play the trombone, he yells into the microphone and turns to Michelle ( who is sitting towards the left of the row of seats).

Continuity mistake: When Jim's dad mentions the webcam thing from the PTA meeting, he turns his head away from Jim. In the next shot, his head is suddenly facing Jim. (00:06:40)
Factual error: The end credits to the movie, which features the Harvey Danger song "Flagpole Sitta" (1997), incorrectly credits it as "I'm Not Sick But I'm Not Well" by LIT. No such song exists, nor have LIT or any other group ever officially recorded covers of "Flagpole Sitta."
Suggested correction: Please indicate which version you saw this on (and possible screenshot). All the versions I've seen, including IMDB, don't even list this song (or it's incorrect title) in the credits. LIT is only credited for 2 songs; "Last Time Again" and "Place in the Sun" for "American Pie 2." The song "Flagpole Sitta" by Harvey Danger does appear in the first "American Pie" film, however the credits I've seen, including IMDB, gives the correct title and correct performed by credit.
Continuity mistake: Jim's mom drops the Tupperware of food with the top facing up, and when it lands, the top is facing down instantly. (00:03:30)
Factual error: The movie takes place in Michigan, however when the boys first arrive in town, a sign reading "United States Post Office Seal Beach, California 90740" can be seen in the background. (00:21:55)
