Character mistake: When Neal tells Rebecca about an Indian Idol and describes the idol to her, she tells him it's the Hindu Idol of Seeta, the goddess of wealth. Actually the idol is of Goddess Laxmi.
Continuity mistake: In the scene explaining the history of the missing jade elephants, they are described as being given to ambassadors by the emperor Zhu Di of China when the Forbidden City (in China) was first opened to foreigners in 1421. When the elephants are all brought together, the representative Daichi Yoshida from the Japanese embassy comes to pick them up, describing them as "a priceless piece of our history."
Point Blank - S2-E9
Factual error: In the scene where Mozzy is using a synthesizer to try and figure out the musical code, he starts playing random chords in frustration. Since the synthesizer is a Minimoog (a monophonic instrument) this is impossible. (00:12:45)
Shot Through the Heart - S5-E11
Continuity mistake: Near the end of the episode, when Peter and Elie are drinking champagne to celebrate going to Washington, the amount of champagne in Elle's glass changes several times between shots without her having had any. (01:01:20)
Continuity mistake: Neal chats with the publicist while Burke goes to meet the journalist. Her hair is either tucked behind her right ear in shots from the left, or not in shots from the right.
Power Play - S2-E15
Factual error: In this episode they mention the heat wave affecting NY, but when Neal talks to Sara he asks her how Argentina was and she says it was hot. But if it's Summer in NY (Northern hemisphere) it should be Winter in Argentina (Southern hemisphere).
Other mistake: Burke shows Elle business class tickets, but says they have coach seats.
Withdrawal - S2-E1
Revealing mistake: At 46:24, Peter and Mozzie are sat on a bench. Peter's paper has the exact same wording on back pages as well as the front page. (00:46:24)
Other mistake: When Neil is in prison and has time on his hands, he puts pieces together that were shredded. Neil's name in the file is CAFFERTY, not CAFFERY. Also, in the same scene, the words "e've" can be seen with the W missing. Yet, later on, when Neil shows Burke the final photocopied piece, the W that wasn't there is now visible.
Factual error: Mozzy plugs a laptop into a PBX switch in what can be assumed to be a server room. Somehow, this remarkably grants immediate access to security cameras and elevator controls without so much as an internal IP address or any administrator login access. This is ridiculously erroneous as no security camera or elevator control would even be accessible from a PBX data line, as these are only able to pass voice/phone data and nothing more. (00:27:40)
Character mistake: When talking to Felix at the planetarium, he correctly states that Tycho Brahe's birthday is December 14, 1546. Later inside the planetarium, Felix says they are looking at the sky on Tycho's birthday, but then says in 1592. (00:18:20 - 00:19:05)
Character mistake: If you look at the piece of paper Neil takes from Agent Matthews the word "warrant" is misspelled as "warreant". (00:21:20)
As You Were - S3-E8
Continuity mistake: When Sarah has been looking at Neil's laptop, the order of the books she places on top changes from when she first sorts them to when Neil pushes them off. (00:03:00 - 00:04:00)
Withdrawal - S2-E1
Continuity mistake: In the final bank vault scene when Peter and Neil are being held at gunpoint. Neil explodes dye packs over Renee covering her and her gun in purple dye. However, when Peter grabs her gun it has no dye on it. (00:45:00)
Withdrawal - S2-E1
Factual error: When Neil figures out how much the bank robbers took they say that each of the 4 robbers are carrying 2 briefcases which means they have 8 in total. If you multiply the $960,000 in each case by 8 you get $7,680,000 which is $520,000 off the $8,200,000 the robbers supposedly got away with, not the $1,500,000 Peter says the difference is. (00:41:45)
Factual error: Neil and Mozzi are trying to date an image of the Chrysler building painting. In the process Neil tells Mozzi to scratch off a bit of titanium white paint from the Rembrandt. Titanium white wasn't discovered and made available for artists until 1921.
