All outgoing parcels must have the ZIP code plus the last 4 digits. Example: 90041-3314.
A 1-ounce letter is now $ .60 metered mail, and each additional ounce goes up by .84 up to a 3.5-ounce letter. After that, the mail piece falls into a flat category. Postal Operations can accept your outgoing mail bearing a postage stamp or we can meter the cost for you.
A letter cannot be larger than 6 1/8" x 11 1/2" or thicker than 1/4". If it is out of these parameters then it falls into either a flat or parcel category. Manila envelopes that are typically 9"x12" or 10"x13" are considered flats and pricing for flats starts out at $1.26 for a 1 ounce flat, 2 ounces is $1.50 to $3.66. Flats cannot be thicker than 3/4".
If your mailpiece is out of the realm of a flat, then it will go out as a parcel. If your parcel is over a pound, it will go out as Priority Mail. We are able to offer great savings for priority mail flat rate - inquire at the Customer Counter.
Please check with a Mail Clerk at the Customer Counter for correct pricing or log onto the USPS website.
IMPORTANT NOTICE:
USPS retail stamp is $ .63 for a 1 oz. letter, or send via Metered mail for $ .60 (save a few pennies!).
