It should change to Approved once the passport application gets approved. At this stage, they will print and mail you the passport. Then, I believe the status will also change to "Supporting Documents Mailed", though I haven't checked the status after my passport arrives in the mail.

My expedited passport renewal took five days from the date they received it (6DEC) until the date they notified me it was approved(11DEC). The passport and passport card were mailed on 11DEC in separate mailings and the old passport was mailed 12DEC.

Steps: In-Process -> Approved -> Shipped -> (Sometimes back to "Approved") -> Supporting Documents Mailed
Other possible status: Additional Information Needed

Daughter's renewal (first adult - so post office acceptance) took under two weeks, submitted just after new year. Would have been a day faster if not for MLK holiday.

Spouse adult renewal via standard service:
12/26/23 dropped application into regular mailbox mailed via USPS mail with applicable postage stamps
1/5/24 online status finally updated to show application was received and is in process. I was getting nervous that the envelope had gotten lost.
1/8/24 check cashed
1/16/24 status updated to approved
1/20/24 passport received via Priority Mail

Today when I check the status it shows supporting documentation mailed 1/19/24.

Overall from the time the application showed up in their system on 1/5 it took ~2 weeks until we received it including the MLK holiday in the midst of it which is great timing. I'm just not sure what happened from the time I put it in the mail 12/26 until they got it 1/5 which seems to have been an exceptionally long time and I will not make the same mistake again to mail without tracking.

January 9: Mailed application for passport book and card, USPS priority mail from California
January 11: Arrived at Post Office Philadelphia, PA
January 12: Picked up by an individual
January 15: MLK Day
January 23: Passport Received via Priority Mail

Two weeks 👍

You mentioned you live in California, yet you mailed it to Philadelphia. Did you request expedited service?

According to the State Depatment website, if you live in CA you should be sending it to Irving, TX. Philadelphia is for expedited requests only and/or you live somewhere other than California, Florida, Illinois, Minnesota, New York, or Texas.

Assuming he submitted at a typical passport acceptance location: my experience when submitting domestically at a post office - is that it is the agent processing the application who determines what office it is sent and not the applicant. I suspect it is the same in the poster's case....?

Maybe, but the OP said “mailed”…

Yeah, I see what you mean. I assumed it was using a DS-11 but seeing the OP's handle better to assume it was a renewal. I expect they will not reject it simply because of the state residence - that would be a major inconvenience for all involved.

overseas passport renewal
 

I live overseas. So passport times may be longer than what others stated in this thread.

Sent documents to my embassy on 1/5
Received notification that passport was being printed 1/23
Received notification that my passport was being sent to my embassy on - 1/25
Received new passport today!!! 2/5

A month if you are overseas.

Or drop off and pick up from your local mission and potentially get it back in half that time (as always).

Will update periodically as this moves through the system. Regular renewal by mail, for a passport book and card, with a name change due to marriage.

Other than USPS mishaps, impressive speed by the Department of State - had the application been properly delivered on Jan 30th as it was supposed to be and other timelines held, that'd have been less than two weeks door to door.
