US/CA Post Parameters
At our US post centre, we print on US Letter size paper (8.5in x 11in). You will still need to upload your letter in A4 size, we will automatically resize it for you. You can refer to our letter template guide here.
We use double-window envelopes which are 9.5in x 4.125in in size.
The single address line formatting is the USPS formatting choice, see their example here. We will re-format any 2 line address for you automatically.
The 'to' address has up to 6 lines, each with a 50 character limit:
- Name (First Name and Last Name): 25 characters each
- Address Line 1: 50 Characters
- Address Line 2: 50 Characters
- City/Town: 50 Characters
- Post Code: 50 Characters but usually this will be around 8 characters.
- Country: 50 Characters
