USPS Regulations

If you are designing a postcard or an envelope to be mailed through the United States Post Office then there are a few regulations you will need to follow to ensure that your postcard meets the guidelines required for mailing.

Do Not Round Corners

Post Office will not accept or mail any postcards with rounded corners.
Only round the corners if your design will be used as a flyer or promotional handout.

Standard 4" x 6" Postcard

Standard 4.25" x 5.5" Postcard

Standard 5" x 7" Postcard

Standard 5.5" x 8.5" Postcard

Standard 6" x 11" Jumbo Mailer

Standard 4.15" x 9.5" Envelope

Zone & Color Key

Yellow Area - Do not put any addresses here with a zip code and state, otherwise there may be a chance of your postcards being returned to you.

Red Area - No text or graphics are allowed that are greater than 7% grayscale. This is especially important for the Post Office Barcode Area. Unless you print your own mailing barcodes, this area must be kept clear or your postcards will not be mailed or returned to you.

Choose your own delivery time

How it works

In our checkout page, click the calendar icon with the date that best suits your price and delivery needs. Your package will arrive on or before that date. The different shipping options; Rush Delivery, Fast Delivery, Standard, and Economy, represent different shipping speeds and price ranges. Upon choosing your delivery date, the cost of your shipping package will be automatically added to your total checkout price.

Cut off times

The cut off time for Rush Delivery orders is 5:00pm Pacific Time. You will not receive next day delivery of your product if you put your order in past this cut off period. (OvernightPrints.com cutoff time of 5:00 pm PT is based on the time we receive notification of a payment clearing from the billing agent. Typical credit card payments clear within 5 seconds; electronic checks, however, may take up to 5 business days to clear.)

Envelopes & Mailing Services

Envelopes are excluded from both Rush Delivery, and Fast Delivery options. Including envelopes in a combined product order will automatically delay the delivery of ALL products in that order. Envelopes require a 5-day standard delivery.

We recommend that you place a separate envelope order if you wish to receive quick delivery on other print items.

These delivery options are also unavailable for Mailing Service orders - Mailing Services are also subject to 5-day standard delivery times.
