adresselinje

Adresselinje, meaning “address line” in Norwegian, is a field used in address data collection to capture part of a postal address. In many forms, addresses are entered on multiple lines; the first line (adresselinje 1) typically contains the street name and house number, while the second line (adresselinje 2) accommodates additional details such as apartment or suite numbers, building name, or care-of information. Depending on country and system, more lines may be supported, or a single multiline field may be used.

Usage and variation: In international addressing, the layout of address lines varies by postal authority. Address lines provide a flexible way to accommodate diverse formats, especially when strict componentization (street, city, postal code, country) would be impractical. In data models, adresselinje fields are often stored as separate strings or as part of a single multiline field; they may be mapped to standardized components for validation and mail routing.

Technical considerations: Address lines should support Unicode, accommodate varying lengths, and handle international characters. Validation should be country-aware for postal codes and locale-specific ordering. Optionality is common: line 2 is frequently optional. User interfaces should label lines clearly, provide hints, and preserve user input for printing or shipping labels.
