How long does the USPS first class shipping take from Phoenix to Los Angeles?

The delivery time for USPS First Class mail from Phoenix to Los Angeles typically ranges from 1 to 3 days. This is because both cities are relatively close, and First Class mail generally takes a short time to deliver within the same region12. However, recent changes in USPS delivery standards have extended the typical delivery time for First Class mail to up to 5 days for longer distances, although this may not significantly impact shorter distances like Phoenix to Los Angeles5.
