Option 1: Mail the letter online
- Finish the letter and printable attachments as one PDF.
- Upload the PDF using the file selector on this page.
- Continue to PostalForm with the United States preselected for the recipient address. Your sender-address suggestion remains separate, so enter the real return address in Canada.
- Review the rendered pages, address, eligible mailing services, estimated delivery window, and exact price.
- Pay only after everything is correct. PostalForm then prints, envelopes, and posts the letter.
Option 2: Send it through Canada Post
Prepare a sealed paper envelope that meets Canada Post's Letter-post dimensions, put the destination country on the final address line, and use the current U.S. or international postage category for the letter's weight and format. Deposit an eligible stamped letter through a Canada Post mailing channel, or take it to a postal outlet when you need the postage checked or want an additional service.
How to address a letter to the United States
Use a complete USPS-format address with the recipient name, street address, city, two-letter state code, and ZIP Code. Upload one final PDF with all pages in the correct order. The checkout validator will flag unsupported page sizes, excessive page counts, or address problems before payment.
Documents, goods, and customs
This route crosses customs territories. A document-only letter is treated differently from goods: follow Canada Post's current rules for any non-paper contents and check the destination country's import restrictions.
Canada Post Letter-post accepts paper correspondence and similar paper enclosures, but not goods or small packets. If the envelope contains merchandise or a non-paper item, choose an eligible packet or parcel service and complete any required customs information.
Delivery, proof, and pricing
For a self-mailed letter, Basic Letter-post is the economical correspondence service. Proof and tracking choices depend on the destination and the Canada Post product currently offered, so confirm them in the destination listing or at a postal outlet before mailing.
PostalForm currently offers standard, expedited, and Certified Mail options for eligible letters to the United States. Checkout is authoritative for the actual PDF and addresses and shows the eligible service, estimated delivery window, and exact price before payment.
Before you send
- Use a final PDF or a sealed paper letter with every page in the correct order.
- Confirm the recipient name, postcode or PIN code, locality, and country.
- Keep goods, cash, hazardous materials, and anything needing a customs declaration out of a document-only letter.
- Use the carrier's current calculator for a self-mailed letter, or PostalForm's checkout for an online order; rates and eligibility can change.
- Choose a proof service only when its delivery record matches what you actually need.
