How to write an address correctly?

See here for practical information on formatting your addresses.

The reliability and speed of delivery very much depend on the care you take when writing your recipients’ addresses. You can help us very easily by following these few recommendations.



Use the right font:

  • Don’t use decorative, ornamental, script or condensed fonts 
  • Letters must not be too “thick” or too “thin”
  • Use a single font 
  • The ideal size of characters is between 10 and 12 points
  • Characters and lines must not touch 
  • Recommended fonts: Arial, Century, Courier, Mangal, Raavi, Tahoma, Tunga, Verdana.


Address field

Write the address carefully:

  • The address should be aligned to the left
  • It must have no more than 6 lines
  • The interspacing must be normal; don’t leave too much space between each line
  • Don’t underline anything
  • Write the postcode very clearly
  • If the recipient has a PO box or bulk user code, don’t repeat details of the geographic address.
  • For less common numbers such as 6/8 rue des Bains, we will only take the first digit into account, i.e. 6 rue des Bains.


You can use our postcode search application to avoid mistakes.


Sender field

Include the sender’s address:

In case the letter cannot be delivered, it is important to write the sender’s address 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.


A few examples of address writing

For Luxembourg :

  Geographic address:

  Mr Jean Schmit
  71, route du Vin

  Postal address:

  Société PWD
  BP 1234
  L-9874 REMICH

  Bulk user postal address:

  Post Courrier
  Customer Service



The country must be written out in full in capital letters on the last line, preferably in French; this is essential for countries that use alphanumeric postcodes (e.g. United Kingdom).

If the postcode is numerical only, the country name can be skipped, but in this case the code must be preceded by the international vehicle registration or ISO code.

  Madame Delphine Dubois
  24, rue Mirabeau
  75016 PARIS

  Herrn Werner SCHMITT
  Beethovenstrasse 32
  CH-8050 ZURICH

  Tate Modern Museum
