Local branches of Santander Bank, JPMorgan Chase and First Republic Bank closed down in September, according to OCC’s latest data.

Santander’s branch at 486 Lincoln St. in Worcester, Chase’s 800 Boylston St. branch in Boston and a First Republic branch at 1 Post Office Square in Boston.

There were two branch openings approved by the OCC, both from JPMorgan Chase as it pursues its Massachusetts expansion plan. Two branches of Citizens Bank and NBT Bank also relocated during the month.

Chase, which acquired the failed First Republic Bank in May, earlier disclosed that it will close down a total of 21 branches nationwide after it absorbed 84 branches from First Republic following the latter’s failure this summer.

First Republic’s website shows four of its branches are still open in Massachusetts in addition to its Post Office Square location: 160 Federal St. in Boston’s Financial District, 772 Boylston St. in Boston’s Back Bay, 47 Brattle St. in Cambridge and 284 Washington St. in Wellesley.

Briana Curran, Chase’s vice president for US regional communications said the employees of the closed branches will still be retained for six months, and then they can apply for any positions within the bank.

“Employees in these offices were offered a six-month transition assignment, after which they’re eligible to apply for open positions within JPMorgan Chase. We currently have 13,000 open roles at the firm and are continuing to open new branches across our 48-state footprint,” Curran said.

While Chase is in the middle of an expansion in Massachusetts, Santander is trimming its branch network as it undergoes a major reorganization.
