Finland has two official languages: Finnish , spoken by 94% of the population; and Swedish , spoken by 6%. Some 22 900 of the Swedish speakers inhabit the Åland Islands, where they form 95% of the population. The Swedish speakers are concentrated in two areas, along the southern coast between Helsinki and Hangö, and along the western coast between Pori and Jakobstad.
There are 24 municipalities that are unilingually Swedish, 17 with a Swedish majority and 23 where the minority is Swedish (in all cases, the municipality must contain at least 3000 people or 8 per cent of the population as Swedish speakers to be declared bilingual). The names of the relevant municipalities are listed in the place names section of this chapter.
There are 10 000 speakers of Karelian in northern Finland close to the Russian border; 4-6 000 speakers of Romany and 7 000 speakers of three dialects of Saami (Sámi) in northern Finland, especially around the town of Utsjoki. There are also scattered speakers of Livvi .

People are legally obliged to have at least one given name and one surname, and may have no more than three given names. Names may generally be chosen freely but may not be used predominantly for naming the other sex, may not be foreign to Finnish naming traditions, may not be a surname (except for a patronymic as the last given name) or (if only one name is to be given) already be in use by a sibling. These rules may be waived in some exceptional cases.
Since 1986, married Finns may take either the family name of the husband or wife, or retain their pre-marriage family names. Children take the shared family name, or one of the names if each parent has retained their pre-marriage names. All siblings share the same family name. Some women also use double-barrelled (hyphenated) family names upon marriage, e.g. Aarikka-Stenroos, the first being the pre-marriage family name, the second being the husband’s family name.
Tables of names can be acquired: given names , surnames/family names , family name prefixes , forms of address , job titles

Finnish addresses are written in this format:
Recipient name Thoroughfare[ ]number [ ] postal code[ ]TOWN NAME {[ ]sorting code}
For example:
The Finnish Post Office prefer addresses to follow a fixed six-line pattern with blank lines where necessary so that each component of an address will always fall on the same line:
Name Company Name Street Address blank line postal code[ ]SETTLEMENT NAME Country name
There should be two spaces between the postal code and the settlement name.
More recently addresses are most often found without any empty lines and without any sorting codes used:
In multilingual areas street addresses can be given in either language.
Jais the Finnish word for ‘and’.
In Finnish, articles do not exist as separate words but are added as endings to the words to which they refer. There is no separate word for Saint in Finnish.
The Finnish postal authorities prefer that ’FI-’ is placed before the postal codes, but the rules of the country from which the mail is sent must define if you do this - please refer to Formatting an international address.
Please refer to the chapter on Sweden for information on Swedish.
A table containing information about the relevant position of elements within address blocks can be acquired

Postal codes (Postinumero) are composed of a block of 5 digits. These are written on the same line, and before, the town name. The first 2 digits of the postal code indicate the area of Finland covered (the sorting office). The next two digits indicate the area within this region (on the basis of municipality/village or suburb). The last digit is usually a 0 (ordinary postal code) or a 1 (post office box). Note that large-user postal codes may also end with a 0 or 1.
In larger towns a sorting code following the town name may be found. For example:
02361 ESPOO 36
The Finnish Post Office prefers that this sorting code, which is included in the postal code, not be used.
Some isolated areas do not have door-to-door postal deliveries, and these areas are served, especially for newspaper deliveries, by buses. These delivery lines have postal codes ending in 899.
The Finnish postal authorities prefer that ’FI-’ is placed before the postal codes, but the rules of the country from which the mail is sent must define if you do this - please refer to Formatting an international address.
In many towns in Finland, different streets, and different house numbers within those streets, belong to different postal code areas.
Metadata containing postal code formatting rules, exceptions and regular expressions can be acquired
