Tools

• analyze_phone_number

  Analyze a number using versioned numbering metadata. National numbers need numberCountryCode; exit prefixes need originCountryCode. Reports uncertainty and rule evidence, never live subscriber status.

  shallow
• compare_phone_numbers

  Compare two numbers after analysis. Missing context produces indeterminate. Extensions must match unless extensionPolicy is explicitly ignore; equality does not establish ownership.

  shallow
• diagnose_dialing_problem

  Explain formatting issues and propose reviewed prefix repairs for confirmation. Uses the same analyzer. Cannot determine why a network rejected a call.

  shallow
• find_calling_windows

  Find overlapping working hours using explicit IANA time zones and dates. Handles overnight shifts and DST; never infers location from phone numbers or contacts participants.

  shallow
• format_international_phone_number

  Normalize a phone number into a plausible international format using reviewed country-specific rules. Processing is ephemeral. This tool does not query carriers, HLR/HSS, MNP databases, or live subscribers.

  shallow
• get_dialing_instructions

  Prepare origin-specific dialing guidance for reviewed countries. Provide origin and destination separately; no phone number returns safe placeholder patterns. Network-dependent results remain conditional.

  shallow
• get_phone_capabilities

  Discover supported countries, per-operation review coverage, evidence, dataset versions and request limits before choosing a phone workflow.

  shallow
• get_phone_input_rules

  Get reviewed display placeholders and trunk-prefix guidance. Examples are not validation masks. English fallback and unsupported editorial coverage are explicit.

  shallow
• lookup_country_calling_code

  Look up international country calling codes by free text, ISO code, dial code, or region. Optionally return reviewed, source-linked dialing examples. This tool does not verify live subscriber numbers.

  shallow
• normalize_phone_numbers

  Normalize up to 100 records with unique IDs. Invalid records produce individual errors. Optionally identify canonical duplicate candidates; no contacts are changed or stored.

  shallow
• resolve_phone_region

  Resolve a phone number to metadata-backed country candidates or non-geographic numbering. Results are numbering assignments, not current location or carrier.
