Whether you're reaching a business contact in Helsinki or calling a person traveling through Lapland, this guide covers everything you need to dial Finland correctly, format Finnish phone numbers, and avoid common mistakes that cause calls to fail.
The country code for Finland is +358. It is required before every international call to a Finland phone number, whether you're calling a landline or a mobile phone. The code +358 is used for routing phone calls to Finnish numbers internationally.
Finland's dialing code is part of the international E.164 numbering system, which standardizes telephone number formats worldwide. The ITU allocated Finland the country code +358 in the 1960s, and Finland shares the +35 zone with other Nordic countries.

When people search for "country code Finland" or "code for Finland" in a calling context, they specifically mean +358 placed before the national phone number. Finland uses the same country code for both landlines and mobile phone numbers, so there's no separate code to remember.
Calling Finland from any country follows a standard sequence: your exit code, then the Finland country code 358, then the area code or mobile prefix without the leading 0, then the local number. The exit code (also called an international access code or international prefix) is the sequence your country requires to initiate an international call. Common examples include 011 for the US and Canada, 00 for most of Europe and the UK, and variants like 001 or 002 in parts of Asia.
The generic dialing format looks like this:
exit code + 358 + area/mobile code (no 0) + subscriber numberOn any mobile phone worldwide, the plus sign (+) can substitute for the exit code, so dialing +358 works from anywhere. Use the format +358 followed by the local number. The same logic applies whether you're calling a Finnish landline or mobile-only the national portion changes. Keep in mind that calling rates depend on your carrier, plan type, and whether the destination is a landline, mobile, or special service number.
The US and Canada share the same international dialing procedure using 011 as the exit code. The exact sequence is:
011 + 358 + area/mobile code (no 0) + local numberHelsinki landline example: 011 358 9 123 4567
Finnish mobile example: 011 358 40 123 4567
On a mobile phone, you can skip 011 and simply start with +358, for example +358 9 123 4567. International calling rates from North America vary widely between operators, so if you're calling abroad frequently, check whether your carrier offers an international add-on pack that includes Finland.
Most European countries use 00 as their default exit code. The format from Europe is:
00 358 + area/mobile code (no 0) + local numberFor example, calling Helsinki from Germany: 00 358 9 123 4567.
On a mobile phone, you can skip 00 and dial +358 directly, which is more reliable when traveling.
Travelers using local SIMs or eSIMs in the EU follow the same +358 format for any Finland number. Travelers in the EU can also use mobile phones in Finland under "Roam Like at Home" rules, meaning your home plan's rates often apply.
Some countries have alternative carrier selection codes, but the Finland country code and Finnish phone number format always stay the same.
Finnish phone numbers consist of the country code +358 plus a national number that is either geographic (landline) or non-geographic (mobile, corporate, or service). Finnish geographic area codes vary in length-some are one digit after the trunk prefix 0, others are two or three digits.
The leading 0 in a Finnish area code is a trunk prefix used only for domestic calls. Remove the leading 0 when dialing Finland from abroad. For example, domestic "09" becomes "9" after +358. Finnish phone numbers have 8–10 digits after +358, depending on the area code and line type.
Some short codes like the emergency number 112 are only dialable inside Finland. Travelers dial the emergency number 112 in Finland without a country code prefix. Emergency contacts should be saved with the +358 prefix for travelers so they work from any phone, anywhere.
Area codes are assigned by Traficom, Finland's communications regulator, and correspond to specific cities or regions. The autonomous region of Åland also shares the +358 country code (area code 018).
| City/Region | Domestic code | International format |
|---|---|---|
| Helsinki | 09 | +358 9 |
| Turku & Pori | 02 | +358 2 |
| Tampere | 03 | +358 3 |
| Oulu | 08 | +358 8 |
| Lapland | 016 | +358 16 |
| Åland | 018 | +358 18 |
Finnish landline numbers use area code 9 for Helsinki, making it the shortest and easiest to remember. Smaller regions have longer area codes and slightly shorter subscriber numbers to keep total length consistent. If you're unsure of the correct area code, confirm it via the contact or a reliable directory before placing the call.
Finnish mobile numbers and some services use non-geographic prefixes not tied to a specific region. Finnish mobile numbers start with 4 or 5 after the trunk prefix-common prefixes include 040, 041, 044, 0457, and 050.
Due to mobile number portability, a specific prefix no longer guarantees which operator handles the number. Numbers can move between carriers without changing digits.
International format examples:
040 123 4567 ? +358 40 123 4567
050 123 4567 ? +358 50 123 4567
Special non-geographic prefixes (like 0800 for toll-free or 0700 for premium) may carry different calling rates, and many are not reachable from abroad.
Practical examples help ensure you format every Finland phone number correctly when calling or saving contacts. Here's a side-by-side comparison:
| Type | Domestic format | International format |
|---|---|---|
| Helsinki landline | 09 123 4567 | +358 9 123 4567 |
| Tampere landline | 03 123 4567 | +358 3 123 4567 |
| Mobile (040) | 040 123 4567 | +358 40 123 4567 |
| Mobile (050) | 050 123 4567 | +358 50 123 4567 |
The pattern is easy: drop the leading 0 from the domestic number and add +358. The international format works from any mobile phone in the world as long as international calls are enabled on the line. +358 helps identify Finnish phone numbers for travelers who encounter unfamiliar contact details.
Messaging and VoIP apps require the full international format to work across borders. For WhatsApp, enter a Finnish mobile as +358 followed directly by the national number without the trunk prefix 0-for example, +358401234567.
While phones often display spaces for readability (+358 40 123 4567), apps accept numbers with or without spaces as long as the country code is present. When adding a contact, select Finland (FI) in the app's country list to automatically apply +358. Using correct international format also prevents contact sync issues when switching SIM cards or traveling.
An exit code is the sequence you dial to leave your own country's phone network and connect internationally. While exit codes differ by country, the code for Finland-358-never changes.
| Country/Region | Exit code |
|---|---|
| USA / Canada | 011 |
| Most EU / UK | 00 |
| Selected Asian countries | 001 or 002 |
In Finland itself, the international access code for calling abroad is 00, though mobile users often just use the + sign. Dialing +358 from anywhere on a mobile phone automatically tells the network to use the correct international prefix, removing the need to memorize country-specific exit codes.
Most failed calls to Finland stem from minor formatting errors. Common mistakes include:
Forgetting the exit code entirely
Keeping the domestic trunk 0 after +358 (e.g., dialing +358 09 instead of +358 9)
Typing the wrong country code (356 instead of 358)
Leaving out digits in the subscriber number
Some corporate or premium service Finnish phone numbers may not be reachable from foreign carriers. To troubleshoot: verify your exit code, confirm +358 is present, remove any leading 0, and check total digit length. If calls still fail, contact your operator-international calling may need separate activation on certain plans.
Calling rates to Finland depend on your country, operator, and whether you're reaching a landline, mobile, or premium number. Traditional carriers often charge per-minute fees, with different tariffs for landlines versus Finnish mobile numbers.
Many VoIP apps can lower the cost by routing calls over data, though rates vary. If you call Finland frequently, search for international bundles that specifically include Finland numbers.
Finland is in the Eastern European Time zone: UTC+2 in winter (EET) and UTC+3 during daylight saving time (EEST). Optimal business calling times are 9:00–17:00 local Finnish time-adjust for time zones if you're dialing from North America or Asia. Calling Finland is rarely free from regular phone lines unless your plan explicitly covers it; data-based calls between app users may be free but still consume internet data.
Remember: dial +358, drop the leading 0, confirm your digits, and you're connected to Finland every time.
