Straßenkatalog Deutschland, available at strassenkatalog.de, is an online directory of geographic and address information for locations across Germany. Its catalog brings together streets, places, districts, municipalities, counties, federal states, postal code areas, telephone area codes, and vehicle registration identifiers, helping users explore regional structures and find relevant location details. Visitors can search by place, street, postal code, or area code; street results can also be narrowed by postal code.

The site is rebuilding its detail pages to add location and property-related context, including maps and profiles covering residential quality, schools, broadband, charging infrastructure, transport, safety, demographics, and the housing market. Its data platform runs on PostgreSQL, and the site prioritizes official or otherwise reliable public sources. Source references, data status, and import dates are presented centrally.

For deeper real-estate-oriented street and neighborhood analysis, the related site strassenindex.de provides location profiles for properties, land, and micro-locations, as well as property listings accompanied by location profiles.
