Q: How should I validate house numbers using the 'maju_nr' column?

Unlike datasets that provide ranges (e.g., "1 to 100"), the Latvian dataset explicitly lists every single house number covered by the postal code, separated by commas (e.g., "1, 2, 2A, 3, 4B").
Technical Note: You cannot use simple range logic (Start > End). Your system must parse the comma-separated string and check if the user's specific house number (including suffixes like 'A', 'B', 'k-1') exists exactly within that list.

Q: Why does the same street ('iela') appear multiple times?

Long streets in major cities (e.g., "18. novembra iela" in Daugavpils) are segmented into multiple records, each with a unique postal code. You must use the maju_nr column to determine which segment/postal code applies to a specific house number.

Q: What is the difference between Urban and Rural address structures?

The dataset covers both structures, but the fields used will differ:
· Urban (State Cities): Address validation relies on iela (Street) and maju_nr (House Number). Fields like pagasts may be empty.
· Rural (Parishes/Villages): Address validation relies on novads (Municipality), pagasts (Parish), and ciems (Village). In these areas, street names may be absent, and the code covers the wider settlement.

Q: In what language is the data provided?

The dataset is provided in Latvian. It uses official administrative headers:
· iela: Street
· maju_nr: House Number
· novads: Municipality
· pilseta: City/Town

Q: What is the format of the postal code?

Latvia uses a code format consisting of the prefix "LV-" followed by 4 digits (e.g., LV-5401). The prefix is an integral part of the code and is included in the indekss column.

Q: What file formats are included in the delivery?

The package includes CSV, Excel (.xlsx), and TXT formats. All files are encoded in UTF-8 (or UTF-8-SIG) to strictly preserve Latvian characters (e.g., ā, č, ē, ģ, ī, ķ, ļ, ņ, š, ū, ž).
