Detective Jacob "Jake" Peralta is a good enough cop that he's never had to work that hard or follow the rules too closely. Perhaps because he has the best arrest record among his colleagues, he's been enabled - if not indulged - throughout his entire career. That is, until the precinct gets a new commanding officer, Captain Ray Holt, who reminds this hotshot cop to respect the badge.
Detective Peralta's shield number is 9544.
Jake is a white male with dark brown hair and brown eyes.
He is often seen wearing a button down plaid shirt, a hoodie, jeans and a stylish, black leather jacket. At Captain Holt's request, Jake has taken to sometimes wearing a tie. He wears a watch on his left wrist and his police badge on a chain around his neck.
Jake is a very competent detective with an incredibly immature, yet charming personality. He often butts heads with authority and teases his partner Amy Santiago. Jake has trouble expressing his emotions, preferring to crack jokes, but always shares his feeling eventually.
Jake is a Jewish New Yorker, raised by his mother after his dad walked out on them when Jake was seven years old.
As a child, Jake was shortstop on his little league team. His dad was the coach, and after every game would take the team to Sal's Pizza. Halfway through their last season, Roger Peralta left his wife and son.
In the episode Halloween it is revealed that Jake has an Uncle Bob who taught him to shoot chess and backgammon pieces with a BB gun.
Rosa and Jake were classmates in police academy. They bonded over their hatred of the training drills. Later, as detectives, they made a pact to trust each other fully when one offered to do 1,000 push-ups if proven wrong.
Jake has been working at the 99th Precinct for at least 8 years prior to the first season of the show. Before Raymond Holt took over as captain at the Nine-Nine, Jake enjoyed that Captain McGinley would allow him to get away with anything while on the job. He took advantage of McGinley's lax attitude and would participate in games with his coworkers, including the The Jimmy Jab Games.

Anyway, we're not supposed to have any contact, so I should go." - Jake to Amy in "Charges and Specs"
