Just for your information, Applied for a passport renewal, routine processing:
May 5 Mailed Priority Mail 2 Day with Electronic Signature Conformation
May 8 Mail received at the Philadelphia center and signed for
June 16. Application received and showing In Process

Basically, it took 5 1/2 weeks from the time they received it to open the mail and log the application.

Just posting so people are aware of the very lengthy wait time before the passport application will show up in the system, and the 10-12 week processing period starts after it.

It is a routine renewal for me and I am in no rush, I have held a valid passport since 1986 and my first planned trip under the new one is in November, so I can wait it out.
