.pa.us domains list

What is .pa.us TLD

.pa.us is the state-geographic second-level within the .us country-code top-level domain, oriented to Pennsylvania-focused registrations. In practice, .pa.us domains identify public bodies, educational institutions, and regional services, while .pa.us websites signal authoritative, locally anchored information to users and search engines. As a global index, we observe the namespace’s footprint and reach at scale. Our current crawl records 240 active domains and 27 live websites in this space, distributed across 2 countries where the TLD appears through hosting or usage. These counts indicate a compact, purpose-specific zone with limited but measurable activity relative to broader .us usage. For rigorous benchmarking and longitudinal tracking, we recommend working from source-level observations. Download webatla’s .pa.us domain datasets for structured analysis.

History and key features of .pa.us TLD

The .pa.us namespace sits inside the longstanding locality structure of .us, where state and municipal labeling conveys a clear geographic signal. While specific administrative eras vary, the intent has remained consistent: .pa.us domains communicate Pennsylvania affiliation, and .pa.us websites often host civic, educational, or community-facing content. Operationally, DNS presence is a useful indicator of active configuration; we currently observe 27 domains with DNS records. Recent registration cadence is muted: 0 new registrations last week and 0 in November 2025. Together, these indicators suggest a stable, low-churn namespace where additions occur episodically rather than continuously. Teams can validate policy effects and infrastructure shifts by comparing time slices in our corpus. Get webatla’s .pa.us domain datasets to compare trends.

Why and who choose the .pa.us domain

Organizations adopt the .pa.us domain when Pennsylvania scope, public-service alignment, or local trust signals are central. Typical registrants include municipalities, public agencies, school systems, and initiatives serving residents; private entities participate more selectively. For discovery, .pa.us domains clarify jurisdiction, and .pa.us websites can align with compliance or branding needs that emphasize government or community stewardship. Internationally, presence extends beyond borders via hosting and service providers, reflected across 2 countries of observed use. Combined with 240 registered assets and 27 currently live, the namespace remains compact, enabling precise monitoring of change and risk. We surface ownership, DNS posture, and content signals to support due diligence. Download .pa.us domain datasets from webatla for your research.
