4.1.4. Address attribution

The general rules for assigning house number are described in Section Number. Number

Enter the house number as the “Official” name.

Follow these rules when entering numbers:
Abbreviations that you should use in the address:
  • holding → “vl”

  • home ownership → “dv”

  • building → “Bld”
  • Building → “Bld”

  • Structure → “Stru”

  • part → “Part”

  • wing → “fl”

  • position → “pos”, section → “sect”, used in addresses for buildings under construction

  • facility → “soor”

  • pavilion → “pav”
  • section → “sect”
  • room → "pom"
  • litera → “lit”, is used in rarest cases when it's impossible to identify the addresses otherwise. Example (taken from St. Petersburg):

    • If the litera is numerical instead of alphabetical, the address is written as 1lit2 instead of 12

    • If the building doesn't have a number and only has a litera: the address “litera B” is written as litB instead of B

    • If an address contains characters that can be confused with each other (the letters O and I and the numbers0 and 1), it is written as 21litO (with the letter O) and 21litI (with the letter I) and synonyms are added to in the format 21I, 21O (type “synonym, historical”)

    • If there are two real addresses on the same street that belong to different houses and differ only in the word “litera”: one of the addresses is written as “27AA” and the other as “27AlitA” (or “27B” and “27litB”) to avoid duplicate address points
    • If there are two real addresses on the same street that are only different in that one of them uses a space (for example, "3Bld361A" and "3Bld361 A"). In this case, write the litera instead of the space ("3Bld361A" and "3Bld361litA").

    Other cases (not listed above) allow using addresses with the “char” parameter in “Also known as, historical” names, while the official address just lists numbers with no “char” or “ character” labels attached)

  • plot → “pl”, no spaces: pl3.

    If a house located in a locality, a cottage settlement, or a farming co-op lacks an address but its plot has a unique number that acts as a stand-in, you don't need to write pl before the plot number

  • post office → “p/o”.

  • block → “blk” (separated by spaces), is only used for blocks in cemetery addresses:


If the address starts with an additional detail, it is omitted except in the following cases:

  • Omitting it creates a duplicate address.
  • There's a letter designation after it.
  • It refers to a cemetery plot.
All abbreviated terms in addresses (Bld, Apt, etc.) should be uppercase.
  • the abbreviations listed above should be lower-case, see section (excluding characters).

  • use uppercase is used when writing characters, such as: 27litA, where A is a character.

If corner buildings have an address written with a forward slash or have two different addresses (one for each street), then create address points for each of the corresponding streets. Enter Official and Also known as names for each address.

If a fraction is used in the form of the address used locally (including on signage), then the official name should include the forward slash (and the name without the sign should be entered under "also known as").

If a number with no slash is used locally, then enter the official name without one (and use the slash for the "also known as" option).

Also see point


If the "also known as" name is exactly the same as the other address on the same street, don't enter it.
