Look up a single NANP NPA-NXX exchange/prefix. Use when the user has an area code plus exchange such as 425-555, or when deriving the prefix from a phone number is unnecessary. Set include_blocks=true when the user needs portability/pooling detail, the responsible carrier may vary by thousands digit, or the answer should show all block-level assignments. TelcoData fields commonly include npa, exchange/NXX, thousands, state, country, ratecenter, company, ocn, lata, switch CLLI, and tandem CLLI. A thousands value of -1 represents the whole prefix/default aggregate; 0-9 are individual thousand-number pooling blocks.

Search TelcoData's tracked source-record changes in reverse chronological order. Use this for questions about when an NPA-NXX or thousands block changed carrier, OCN, CLLI/switch, assignment status, rate center, or another tracked field. Filters are combined, and omitting all filters returns the most recent changes. Initial baseline-load events are excluded. Multi-field record changes are returned together as structured old/new JSON values rather than one unrelated result per changed field. The clli filter matches switch-related changes and accepts a 6- to 11-character CLLI or prefix. Use field for a lowercase source field name, source for the tracked source name, and limit to cap results.

Look up one thousands block within an NPA-NXX. Use when the user gives the seventh digit of a NANP number, such as 425-555-4XXX, or asks who owns/routes a specific block. If no block row exists, the tool reports whether it used the -1 aggregate/default row. TelcoData fields commonly include npa, exchange/NXX, thousands, state, country, ratecenter, company, ocn, lata, switch CLLI, and tandem CLLI. A thousands value of -1 represents the whole prefix/default aggregate; 0-9 are individual thousand-number pooling blocks.

Normalize a dialable telephone number to E.164 and identify country metadata. Prefer this whenever the user gives a full phone number. For NANP numbers, it returns the most specific TelcoData exchange or thousands-block record and shows whether the lookup used block detail or fallback. TelcoData fields commonly include npa, exchange/NXX, thousands, state, country, ratecenter, company, ocn, lata, switch CLLI, and tandem CLLI. A thousands value of -1 represents the whole prefix/default aggregate; 0-9 are individual thousand-number pooling blocks.

List all exchanges/prefixes in a NANP area code. Use for area-code inventory, coverage, or 'what prefixes exist in 425' questions. Set include_blocks=true only when the user asks for every thousand block or pooling-level detail, because that can return many more rows. TelcoData fields commonly include npa, exchange/NXX, thousands, state, country, ratecenter, company, ocn, lata, switch CLLI, and tandem CLLI. A thousands value of -1 represents the whole prefix/default aggregate; 0-9 are individual thousand-number pooling blocks.

Search exchanges/prefixes for a rate center within a state, province, or NANP country code. Use for local-service geography questions such as 'prefixes in the Seattle rate center' or 'which exchanges are in Hamilton, BM'. Rate-center names are telecom rate-center labels, not always postal city names. Set include_blocks=true for pooling detail. TelcoData fields commonly include npa, exchange/NXX, thousands, state, country, ratecenter, company, ocn, lata, switch CLLI, and tandem CLLI. A thousands value of -1 represents the whole prefix/default aggregate; 0-9 are individual thousand-number pooling blocks.

List newly assigned TelcoData exchanges for a date range. Use for recent numbering activity, new prefix reports, and state-filtered change monitoring. Defaults to the last 30 days when dates are omitted; pass explicit YYYY-MM-DD dates when the user gives a period. Results are exchange-level additions, not live telephone-number assignment events.

List NPA-NXX prefixes assigned to an Operating Company Number (OCN). Use when the user asks where a carrier operates, what prefixes belong to a carrier, or wants to pivot from an OCN profile into numbering footprint. Combine with get_ocn_profile for carrier identity fields. TelcoData fields commonly include npa, exchange/NXX, thousands, state, country, ratecenter, company, ocn, lata, switch CLLI, and tandem CLLI.
