Nothing has been finalized, and the list of possible closures is only preliminary.
With more people using e-mail and online banking, officials say they're not seeing the volume that they used too. It's estimated that 38 billion fewer pieces of mail will be sent in 2009 compared to 2007.
Of the 670 on the list nationwide, experts say about 200 branches will be shut down after a government review. Many of them are in urban areas.
The news doesn't bode well for the three post offices in Inglewood that made the list.
"I think that the post office is real convenient for a lot of businesses around here," said local resident Mark Brule.
The volume the facilities do will probably play a big role in which ones end up being closed.
The Postal Service may also have to look into layoffs in the future.
The postal service says it needs to tighten its belt, but residents don't want anything to change.
"I do a lot of stuff online, online billing, but there's certain things I still do need it for," said local resident Luz Cortes.
