📮FI Finland Regional Postal Code FAQ & Postal Regulations
📮 What is the format of Finnish postal codes?
Finnish postal codes consist of 5 digits only (e.g., 00100). The first two digits indicate the region, while the last three specify streets or neighborhoods.
🔍 How to find a Finnish postal code?
Use the postal code search tool on Posti.fi official website by entering an address or city name. Map apps like Google Maps also provide real-time postal code lookup.
⚠️ Will an incorrect postal code cause lost mail?
Mail with correct addresses usually arrives but may be delayed (up to 5 days). Use Posti's parcel tracking service for real-time updates.
🌍 Are special markings needed for international mail?
Always write "FINLAND" in bold. For parcels exceeding €22 value, include a customs declaration form detailing contents and value to avoid delays.
📬 Do PO Box codes differ from street codes?
Yes! PO Box codes start with "PL" (e.g., PL 100). Never mix street and PO Box codes – this may cause delivery failures.
