Mail collection times are different at each post office and each blue-mail-collection box. Collection times are shown on a small sign attached to the mailboxes and mail slots.
Zip codes are the 5 digit or 9 digit numbers that indicates the postal area in the U.S. The numbers are written after the two-letter state abbreviation. A Zip Code Directory can be found in every post office or obtained by going on the internet at www.usps.com.

Mail is delivered daily to residences and post office boxes, except on Sundays and legal holidays. Post office boxes can be rented at most post offices.
Apartment mailboxes should be clearly marked with the number of your apartment, and possibly your name. If you live in a house, make sure the house number is shown on the mailbox or the mailbox post.
If you are going away, the post office will hold (keep at the post office) your mail for up to 30 days. To use this service, fill out a form at the post office that delivers your mail.
If you receive mail for a previous resident you should mark it “Moved.” If you know the new address for the previous resident, write that on the envelope and place the mail in the mailbox for the mail carrier.
