Addressing items correctly

Items whose format and addresses meet the requirements of modern sorting machines will be processed more quickly. This saves time right after mailing the items in Switzerland.

An envelope is broken down into 4 areas:

• Franking area
• Area for advertising and sender
• Code area
• Address field

1. Area for advertising and sender
2. Franking area 74 x 38 mm (must be left blank for franking, postal payment impression and postal information)
3. The address field must be placed in this area
4. Address field for address, address window or address label
5. No sender information to the right of and below the address
6. Code area (must be left blank)
   up to format B5: Code area 140 x 15 mm
   from format B5 to B4: Code area 100 x 35 mm
