Chapter Two: A Touch of Evil - S1-E2
Continuity mistake: During the pep rally it is raining hard and everyone on the football field is soaking wet, but when Cheryl runs from the field into the locker room followed by Veronica and Betty, they are all completely dry and their hair is perfectly styled.
Chapter Four: The Last Picture Show - S1-E4
Continuity mistake: Archie and Betty are shown as living in houses next to each other, but in shots of their houses, Betty's address number is 111, while Archie's is 2037.
Chapter Four: The Last Picture Show - S1-E4
Continuity mistake: When Ms. Grundy and Archie are watching a movie, her hair switches between shots from behind her ear to in front. (00:14:40)
Chapter Eighty: Purgatorio - S5-E4
Continuity mistake: In Season 4, Archie visits his father's grave. On the grave it says May 21, 1970 - July 3, 2019, but in season 5, Veronica says "It's 2021" Veronica says this seven years after Archie visits the grave, so how has it been 7 years from 2019 to 2021?
Chapter Twenty-Six: The Tell-Tale Heart - S2-E13
Continuity mistake: As someone knocks on the door, Betty drops her bowl of cereal leaving a mess consisting of milk, "Fruity Munch" cereal, and shattered ceramic on the floor. When Betty walks forward to open the door, the floor behind her, where there should be a huge mess, is totally clean. (00:08:01 - 00:08:27)
Chapter Sixty-Eight: Quiz Show - S4-E11
Other mistake: Archie's uncle Frank tells Archie during an argument with him that he is 40 years old, with seven years in combat while in the military. But in a previous episode when explaining why he let Fred take the blame for his DUI, he claimed that he was a Desert Storm veteran in between tours at the time. Either the show got the wars wrong and meant to say he was an Operation Enduring Freedom or Iraqi Freedom veteran (no actual veteran uses "Desert Storm" when referring to combat in the Middle East after 9/11) or they're saying that he was only 10-11 years old when he went to Desert Storm. (00:29:30)
Chapter Seven: In a Lonely Place - S1-E7
Other mistake: Marisol Nichols is listed twice in the opening credits, while Madelaine Petsch isn't listed at all.

Chapter Seventy-Nine: Graduation - S5-E3
Factual error: Archie revealed that he joined the Army to avoid repeating his senior year and was shipping to Basic Combat Training the following morning. Before leaving he would need to wait for his background and medical checks to be completed (including getting his dropped murder charge reviewed for suitability), which could take weeks. Also, the Army usually requires a diploma or GED to ship to basic. There were brief periods when the Army was accepting dropouts but it was not when this episode took place.
Chapter Two: A Touch of Evil - S1-E2
Continuity mistake: At the pep rally everyone says it is raining - on stage mayor McCoy is holding a soaked umbrella while around her no-one is wet, and we see all the cheerleaders completely dry at that moment.
Continuity mistake: When Josie looks at the folder with Archie's songs, and starts singing them, the folder cover is hanging, while she holds it. The cover then ends up tucked into Josie's hand without her moving it.

Chapter Eighteen: When a Stranger Calls - S2-E5
Other mistake: When Betty receives the call from the unknown number, her iPhone rings audibly. When the program shows a closeup of her iPhone, the mute switch is down, meaning the phone is on silent. (00:15:25)
Chapter Twenty-Seven: The Hills Have Eyes - S2-E14
Continuity mistake: When Betty and Jughead are fighting in front of Archie and Veronica, Jughead is holding his drink when the argument first starts. When the camera switches to show Archie and Veronica's reactions, the drink is sitting on the table.
