Despite having ended almost a decade ago, The Office remains one of the funniest and most-watched sitcoms. As it follows a group of characters working together at a paper company, the cast ranges from people in their 20s, such as Jim and Pam, to those around 70 years old, like Creed. The age diversity in the cast enables The Office to explore the work environment as perceived by different generations over time.
Most characters in The Office are still figuring things out, especially the main characters, as they’re in their 20s and 30s. Interestingly, there is a wealth of information available about the exact birthdays of most characters. The audience can know how old their favorite The Office characters are and even their zodiac signs.
Updated on June 9, 2025, by Arthur Goyaz: The Office introduces a vast and diverse set of main characters who make up Dunder Mifflin’s Scranton branch. This was updated to include more characters and their respective ages and to reflect CBR’s current style guide.
Oscar Martinez Is a Sensible Accountant
41 Years Old in Season 9
Born on November 15, 1972, Oscar Martinez was 33 years old at the beginning of The Office. He’s a particularly reasonable and charismatic accountant at the firm. Oscar is one of the few characters on the show who doesn’t seem to have a few screws loose.
Oscar suffered a lot at the hands of Michael Scott because of his sexuality, although the matter was more about Michael’s ignorance than actual intolerance. He is 41 years old at the end of The Office and ready for a significant career leap. While other characters are retiring or fulfilling old dreams, Oscar decides to run for state senator.
Creed Bratton's Age Is Only One of the Many Mysteries Surrounding the Character
Presumably 88 Years Old in Season 9
Creed Bratton is a living mystery in The Office. Working under the title of Quality Assurance Director at Dunder Mifflin, Creed spends most of his time in the office playing solitaire or making creepy suggestions about his past. In Season 4, Episode 1, «Fun Run,» Creed claims to have been born on November 1, 1925, making him 80 years old at the start of the show.
However, Creed’s penchant for lying is no mystery to fans and his co-workers. Creed was famously a drug abuser and dealer in the past, as well as a hippie and a homeless man, let alone a potential murderer. It’s hard to know for sure anything about his life, but at least according to him, Creed was 88 years old in Season 9 of The Office.
Holly Is Michael Scott's Soulmate in The Office
38 Years Old in Season 7
Holly Partridge becomes a regular in Season 5 of The Office and quickly wins over the hearts of the fans. She resembles Michael in her quirkiness and outgoing personality, though she demonstrates a much clearer moral compass. Their similar traits bring the two closer together, and they become romantically involved.
Holly was born on March 3, 1972, making her 35 years old when she first appeared in Season 4. Michael and Holly get married and move to Colorado, where they raise four children. Her final on-screen appearance is in Season 7, Episode 21, «Goodbye Michael.» She’s 38 years old at this point.
Erin Hannon Was Very Young
27 Years Old in Season 9
Erin Hannon was born on May 1, 1986, which means Erin was 22 in the fifth season when she was introduced, and 27 in the last season of The Office. When Pam quits her job as a Dunder Mifflin receptionist, they replace her with Erin Hannon (played by Ellie Kemper). Erin is young, charming, and naive. Suffice it to say, she’s not the brightest bulb on the Christmas tree, but this might be because she was only 22 years old when she started working at the paper company.
Ellie develops quite a romance with Andy Bernard, who is 13 years older than her and already 35 years old by the time Erin arrives at the office. However, their relationship ends after he goes on his boat trip in Season 9 and starts dating the new kind and sweet employee, Pete. At the end of The Office, Erin is 27 years old.
Robert California Replaces Michael Scott for a While
51 Years Old in Season 8
Portrayed by James Spader, Robert California is one of the main characters in the eighth season of The Office. He obtains the CEO position at Dunder Mifflin and becomes the new eccentric boss of the company. Robert has an intense personality and an air of wisdom, but in the end, he lacks just as much common sense as Michael Scott. Robert California was born on February 7, 1960, which means he was 50 years old in the seventh season when the character was introduced, and 51 years old when he left The Office in its eighth season.
Being the boss, it makes sense that Robert is a middle-aged man. He has been married at least three times and has a young son, Bert, who is around 10 years old. However, it’s clear that Robert hasn’t matured at all, but he knows exactly how to get what he wants. In the end, when David Wallace buys Dunder Mifflin, Robert convinces him to donate a million dollars to a charity for college girls in developing countries; the whole thing sounds incredibly shady.
Stanley Hudson Is One of the Funniest Characters in The Office
61 Years Old in Season 9
Stanley Hudson was born on July 14, 1951, which means Stanley was 54 at the beginning of The Office and 61 in the last season. Stanley spent a lot of time working at Dunder Mifflin, and it is clear that by the time the series begins, he is already done with everything and everyone, especially when it comes to Michael Scott. Stanley is a good, reliable salesman, and he isn’t one to be involved in the office’s shenanigans.
Stanley was married, but after an affair, it is unclear if he was still with his wife. He has a young daughter and keeps her picture on his desk — until Michael makes a highly inappropriate comment. In the end, Stanley retires to Florida, where he pursues a wood carving hobby, so all ends well for good ol’ Stanley.
Phyllis Vance Is a Sweet Character
47 Years Old in Season 9
Phyllis Vance was born on July 10, 1965, which means Phyllis was 40 at the beginning of The Office and 47 in the last season. She is later known as Phyllis Vance once she gets married to Bob Vance, Vance Rerigeration. She is not as old as people think. Phyllis has a serious and quiet personality with a conservative fashion, but as she remarks all the time, she is the same age as Michael.
Despite Phyllis’s introverted nature, she has a gossipy side and likes talking with the other members of the office. However, she endures many humiliations thanks to Michael, who sees her as an old grandma. Phyllis leaves Dunder Mifflin after the ninth season of The Office and opens a knitting store after reuniting with her long-lost daughter.
Toby Flenderson Never Had a Happy Life
49 Years Old in Season 9
Toby Flenderson was born on February 22, 1963, which means Toby was 42 at the beginning of The Office and 49 in the last season. Likely no one who has watched The Office would believe Toby is only two years older than Michael. Toby is a solemn, quiet man who tries to keep order in the office, but most of the time, Michael sabotages him. He also has a tense relationship with Michael, who resents him because Toby, as an HR representative, has to keep Michael in check.
Toby had the worst luck throughout The Office. He got divorced, he had a terrible time at Dunder Mifflin, and he didn’t seem to have any friends. Furthermore, Toby is fired in the last season after the documentary airs, so he quite literally ends up having nothing. Some people believe Toby was Scranton’s Strangler.
Kelly Kapoor Is One of the Youngest Workers at Dunder Mifflin
34 Years Old in Season 9
Kelly Kapoor was born on February 5, 1980, which means Kelly was 25 at the beginning of The Office and 34 in the last season. One of The Office‘s writers, Mindy Kaling, portrayed Kelly Kapoor as Dunder Mifflin’s Customer Service Representative. Kelly was the youngest character in the main cast, and she was often caught up in a toxic on-and-off relationship with Ryan Howard. The character left in the ninth season when Kaling started her own show, The Mindy Project.
Kelly leaves The Office when she moves to Ohio with her boyfriend, Ravi. However, she still appears in the ninth season as a guest character. Nine years later, Kelly is still figuring things out, and the show makes it pretty clear that Kelly cheats on Ravi with Ryan, so that relationship also doesn’t get any better.
Kevin Malone Is Older Than People Think
52 Years Old in Season 9
Kevin Malon was born on June 1, 1961, which means Kevin was 43 at the beginning of The Office and 52 in the last season. Despite his youthful personality, Kevin is already in his forties at the beginning of The Office. Kevin is Dunder Mifflin’s accountant, but he is not very good at his job. In fact, Angela and Oscar are always covering for him. Still, Kevin is an affable and charming character that earned the hearts of the viewers.
At the end of The Office, Dwight fires Kevin because he has made too many mistakes in his books, having invented a number called «keleven.» However, it is later revealed that Kevin opened his own bar, and he forgives Dwight for firing him, so it seems that all is going well for Kevin after all.
