San Francisco defeated the Seattle Seahawks 21-13 on Thursday night at Lumen Field to claim its first division title since 2019 and 22nd overall.
The 49ers finished third in the West one season prior to winning the division title.
The 49ers will have an edge going into the playoffs this year since division winners are assured a top-four seed in their respective conference.
The 49ers (10-4) are currently the No. 3 seed in the NFC, one game behind the Vikings (10-3) who are in first place in the North.
To overtake the East-leading Philadelphia Eagles (12-1) for the top spot and a bye in the NFC first round, the 49ers would require a lot of assistance.
The 49ers would play host to the No. 6-seeded Washington Commanders (7-5-1) at Levi's Stadium if the playoffs started the following week.
The 49ers (10-4) continued to demonstrate they might be the class of the NFC alongside Philadelphia despite utilising their third starting quarterback this year.
San Francisco 49ers won its seventh game in a row by frustrating Seattle into making numerous errors with its oppressive defence.
