First-Class Postage International postcards, letters, and big envelopes (flats) must be labelled "AIRMAIL/PAR AVION" or have PS Label 19-A, Par Avion Airmail, or PS Label 19-B, Par Avion Airmail, applied to the address side. Smaller envelopes do not require a special code.
Any letter sent by First-Class Air Mail service must comply with all the requirements of that service. Such letters may be sent from, to, or within Canada or between Canadians and people in other countries. They must be written on airmail paper (110 lb stock), measured 1-1/4 x 5-7/8 inches, and come with a postage stamp attached. There is a limit of 10 grams of moisture per square meter, so if the letter contains food items or other products that are prone to spoilage, they should be sent in an insulated package or mailed dry.
People send millions of letters every day. To help ensure that they reach their destinations, the Canadian government imposes certain requirements on those who send letters by post. The most important requirement is that you must provide evidence that your letter has been sent by certified mail. This can be done by including a prepaid return receipt with your letter or emailing a copy of the confirmation number to the address that you provided.
The use of electronic messaging such as email is very popular today. It's easy, fast, and reliable.
International Standard products (excluding those sent from Northern Ireland to the Republic of Ireland) require an AIR MAIL sticker or the words "BY AIR MAIL—PARIS" in the upper left corner. Products from Northern Ireland can be sent to any other part of the United Kingdom and requires a STANDARD POST sticker.
You can also write "PARCEL POST" or "BY EXPRESS POST" if you want to send documents by courier instead. The cost is higher but it's guaranteed to arrive within 5-7 business days.
Writing boxes are available at most post offices, or you can use Yahoo! Mail, Gmail, or another email service. Just make sure that you write your address correctly!
In case of loss, Yahoo! Mail, Google Mail, or another email service can help identify the sender. They'll need information about you called a "dossier", which includes name, address, phone number, and email address.
For security reasons, do not use a box number or postal code as your address! Also, do not use a mailbox located at a rental property - they will not be responsible for lost packages.
The usual design is a plain blue oblong with the phrases "AIR MAIL" and/or "PAR AVION" in white letters. In some countries, such as the United Kingdom, one may simply write "PAR AVION—BY AIR MAIL" on the envelope, even though etiquettes are available free from post offices.
In fact, "PAR AVION" was originally used by French mail carriers who delivered letters by balloon flight. The first aeroplane post office opened in France in 1910, so "PAR AVION" became associated with aerial post delivery.
Since 1967, when regular airmail prices were introduced, "AIR MAIL" has been used for all classes of service. However, "PAR AVION"—which indicates that certain restrictions apply to this letter depending on its class (for example, letters sent by ordinary post cost more than those sent by airmail)—is still permitted on airmail envelopes.
There are also regional variations of the standard form. For example, in Germany "AIR MAIL" is usually written in large, eye-catching type while "REGISTERED POST" is printed in small, inconspicuous type. Many German-language posts use a single form for both types of letter.
In Italy, Spain, Greece, Indonesia and Vietnam, various forms are used for different classes of service.
