Poland - Languages


The official language, Polish External, is spoken by 98% of the population. Ukrainian External is spoken by about 1 500 000 people; German External by 1 400 000 people; Belorussian External by 230 000; Kashubian External by 200 000 and Romani External (in four forms) by about 30 000 people.

Poland - Personal names


It is required by law for a given name to clearly indicate the person's gender.

Children usually take the surnames of their fathers. It is becoming popular to take two surnames (one from each parent). For example, Plichta-Bakowski, Plichta from the father and Bakowski from the mother. Female spouses often have double surnames (hyphenated), the first part her maiden name, the second the surname of her husband. Rarely, women do not take their husband’s surname, or children take the mother’s surname.

Polish names are usually written given name first, surname last. Females who take their husband’s surname may take a feminized form of the name. The wife of Mr Kowalski may be Mrs Kowalska. Polish surnames also take different endings according to a complex set of declensions. Mr Kowalski and Mrs Kowalski together become Mr and Mrs Kowalscy. These alter according to case and singular/plural, and the stem of the name, giving potentially up to 50 different written forms of the same surname.

Poland - Addresses


Addresses are written in this format:

   Form of address
   Recipient name 
   thoroughfare type[ ]Thoroughfare name[ ]number
   postal code[ ]SETTLEMENT

For example:


The form of address may also be written on the same line as the personal name, especially when a company name occupies the top line of the address block.

Sorting codes (a number after the settlement name) are sometimes found in addresses but they are not required.

Thoroughfare types are written beginning with a lower-case letter.

The house number may be followed by an ‘m’ or ‘/’ to indicate a flat number. In the following examples of layout, the house number is 12, the flat number 3:

   ul. Mala nr 12 m. 3
   ul. Mala 12/3
   ul. Mala 12 m. 3
   ul. Mala nr 12/3

Additional numbers or characters may indicate different entrances to the building. For example:

   ul. Mala 12/4/223
   ul. Mala 12A/3

In all cases the house number layout is familiar to Poles and the Polish Post Office and should not be altered.

Some villages have no street names - each house has its own number, which follows the village name like this:

   Mscijewo 11

Osiedle (Os.) may appear in an address to indicate a housing estate
