How long does it take mail to get from auburn California to San Diego Ca?|196169

I have friends that live in San Diego Ca and I am curious to find out: how many days it would take them to get a letter I send from auburn Ca...I tried google but no answer was found. Thanks for the help.

2-4 days. A lot depends on when you mailed it and where you mailed it from.

For example if you mailed it on Saturday afternoon after the post office already picked up at that location, then they won_t get it going until Monday. Under those conditions it could be 5 days.
