How to write an address clearly
Everything you need to know about addressing your mail correctly
Delivery speed and reliability depend to a large extent on how carefully you write your recipient's address. That's why quality of service also depends on you. It's simple to play your part: just follow these few recommendations.
Font:
- Avoid using decorative, ornamental, script or condensed fonts.
- The weight, i.e. the "thickness" of the letters should not be too light or too heavy.
- Use a single font for the whole address.
- The minimum font size should be 8 point or above; 10 to 12 point is ideal.
- Characters and lines should not touch each other.
- Recommended fonts: Arial, Century, Courier, Mangal, Raavi, Tahoma, Tunga, Verdana.
Only write in the address area

Write the address carefully
- Align the address to the left.
- It should consist of a maximum of 6 lines.
- Spacing between lines must be normal: do not leave too much space between two lines.
- Do not underline anything.
- Write the post code clearly.
- Use the correct layout
- Do not add unnecessary information to the address: if the recipient has a PO box or a bulk user code, do not repeat the details of their actual geographical address.
- For less common numbering such as 6/8 rue des Bains, we recommend just using the first number, i.e. 6 rue des Bains.

Examples of addresses abroad
The name of the country must be included and written in capital letters and preferably in French; this is essential for countries with alphanumeric post codes (such as the United Kingdom).
If the post code is in numeric form only, it is not necessary to write the name of the country, but the post code must be preceded by the international country code used for vehicle registrations or the ISO code.

Include the sender's address
In case the letter cannot be delivered, it is important to write the address of the sender so it can be returned to the correct address. Write the complete address of the sender on the back of the envelope (on the flap) or on the front in the top left-hand corner. This is compulsory for registered mail.
