Abstract:

   Map-based discovery systems can help a person identify nearby
   businesses, properties, service providers, hotels, clinics,
   restaurants, and other commercial actors, but discovery frequently
   transitions into communication through a persistent telephone number,
   reusable virtual number, open message thread, callback route, or
   other contact path.  A person may intend only a short first
   conversation with several candidates, while the communication
   mechanism unintentionally creates continuing reachability after that
   inquiry has ended.

   This document describes an architecture in which first contact and
   future reachability are separate authorization events.  After a user
   creates a map search, property inquiry, service request, booking
   inquiry, quote request, or similar context, a platform can create a
   query-scoped non-bearer communication reference and bounded preview
   authority.  A user or eligible business can participate in a real but
   limited first interaction.  Continued communication is separately
   authorized and remains bound to attributes such as the original
   query, business identity, purpose, channel, effect, validity window,
   nonce, quota, revocation state, and enforcement point.  Possession of
   a number, handle, previous conversation, lead assignment, API
   credential, or payment event is not by itself sufficient future-
   contact authority.

   The architecture separates marketplace policy from communication
   effectuation.  A Communication Authority Service creates a protected
   authorization binding, while an enforcement point reconstructs the
   actual attempted communication, checks current protected state,
   atomically reserves or consumes relevant authority, and releases the
   communication-bearing resource only after successful verification.
   This permits privacy-preserving first contact, controlled future
   reachability, preview-qualified lead monetization, and AI-assisted
   business discovery without requiring a new public telecom protocol
   for initial deployment.  Google Maps, Apple Maps, mobile operating-
   system discovery surfaces such as iOS and Android, and social and
   commerce platforms with map-adjacent or messaging-based business
   discovery features such as Meta Business (including Facebook and
   Instagram business discovery and messaging) are used as recognizable
   illustrative examples; no affiliation, endorsement, implementation,
   adoption, or technical alignment by Google, Apple, Meta, or any other
   named provider is implied.

   The architecture's binding of recipient identifiers to pseudonymous,
   query-scoped, time-limited, purpose-bound, and revocable
   authorizations rather than persistent contact data is consistent with
   the data protection principles of the EU General Data Protection
   Regulation (GDPR) -- including data minimization and purpose
   limitation (Article 5), storage limitation through bounded validity
   and quota, and privacy by design and by default (Article 25).  This
   document describes a technical architecture only; it does not
   constitute a legal compliance determination, and conformance with
   GDPR or any other data protection law depends on the specific
   deployment, controller and processor roles, and operational practices
   of an implementing platform.
