  description

  AddressWiki Browser Extension adds structured USPS-related signals directly into the provider pages you already use.
  
  While browsing locations on Location website of providers, the extension displays AddressWiki reference data and selected USPS address signals in a side panel so users can review mailbox locations without switching tabs.
  
  Supported provider sites:
  
  iPostal1
  Anytime Mailbox
  PostScan Mail
  
  What the extension shows on supported pages:
  
  • Selected USPS and address signals such as CMRA (Mail Receiving Agency), USPS Deliverability Status, Building Type, Vacant Address, Carrier Route, and ZIP+4 Code
  • A direct link to the corresponding AddressWiki.com detail page for deeper analysis
  
  AddressWiki.com website capabilities:
  
  Aggregates 6,800+ virtual mailbox records across 7 main provider networks.
  Search smarter, compare faster, and analyze deeper with AddressWiki.com. The full comparison workflow takes place on the AddressWiki website.
  Users can open the related AddressWiki page from the extension to access more advanced analysis tools.
  
  On the AddressWiki website users can:
  
  • Find 30+ structured USPS and address signals such as CMRA (Mail Receiving Agency), RDI (Residential Delivery Indicator), DPV notes, USPS deliverability status, and related indicators
  • Filter mailbox locations using structured USPS and address-quality fields
  • Sort results by price or rating
  • Review deeper field explanations and structured address signals
  • Explore map views and location context
  • Compare mailbox providers across multiple locations
  
  Furthermore, Our AI Scoring evaluates each address across multiple signals such as authenticity, deliverability, stability, and usage profile, then scores it under three key scenarios: Financial / Digital Nomad, E-Commerce / Corporate Use, and Online Business Operator, so users can quickly understand which address is best suited for their needs.
  
  Who it is for:
  
  Cross-border sellers and e-commerce operators
  Digital nomads and remote teams
  Small business owners evaluating virtual mailbox providers
  Online business operators comparing mailbox addresses across providers
  
  Important notice:
  
  AddressWiki provides analytical signals and reference information only.
  Mailbox services themselves are provided by the original mailbox providers. Pricing, availability, and provider policies may change over time. Users should confirm final details directly with the provider before making a purchase decision.
  
  Privacy and permissions:
  
  The extension only runs on supported mailbox provider pages and only accesses the page data necessary to display AddressWiki information in the side panel.
  The extension does not sell user data and does not use browsing data for advertising.
