Postal Information

All outgoing parcels must have the ZIP code plus the last 4 digits. Example: 90041-3314.

A 1 ounce letter is now $ .50 metered mail, and each additional ounce goes up by .65 up to a 3.5 ounce letter. After that the mailpiece falls into a flat category. Postal Opeartions 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 than it falls into either a flat or parcel category.  Manila envelopes that are typcially 9" x 12" or 10" x 13" are considered flats and pricing for flats starts out at $ 1.00 for a 1 ounce flat.  2 ounces is $1.15 to $2.80. Flats cannot be thicker than 3/4".  

If your mail piece is out of the realm of a flat than 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 - inquire at cusomer counter.

Please check with a Mail Clerk at the Customer Counter for correct pricing or log onto the USPS website.


**All mail and parcels will be held at Oxy Postal Operations during the winter break. 
No forwarding will take place unless you are studying abroad,  taking a leave of absence, or withdrawing permanently.  Our system will automatically give us a mailing address from your MyOxy account if any of the above takes place.

Please do not call the USPS and request your mail held as it is not a service they provide for you.
