Everything in Extended Lookup

Operating carrier (OCN, class, DBA), corporate holding company, line-type utilization codes, portability, block geography, and the wholesale-hosted flag.

nxxCarrierMix

Every carrier operating blocks in the number exchange (NPA-NXX), with per-carrier block counts, OCN class, and wholesale flags — who else lives in this exchange besides your number.

nxxSummary

The single-number risk overview: totalBlocks, wholesaleBlocks, wholesaleShare (0–1), and carrierCount — no client-side math needed.

Wholesale share as a list signal

An exchange with a high wholesaleShare concentrates reseller, VoIP-app, and second-number inventory. That is where churn and suppression pressure actually lives.

Host vs reseller in one view

See the split between host-MNO blocks (AT&T, T-Mobile, Verizon families) and enabling carriers (Onvoy, Bandwidth.com, Peerless, Inteliquent) without a second query.

Investigation-grade context

Switch CLLI, wire center, rate center, county, CBSA/MSA, coordinates, and timezone — enough to audit any routing or suppression decision afterwards.

The exchange lens: what Full Data adds

A real response from a Teaneck, NJ exchange — one-third of the exchange sits on wholesale infrastructure, exactly where second-number apps and MVNO eSIMs concentrate:

{
  "nxxCarrierMix": [
    { "carrier": "Bandwidth.com", "ocn": "118F", "ocnType": "CLEC", "blocks": 4, "isWholesaleHosted": true },
    { "carrier": "CSC Voice",     "ocn": "612K", "ocnType": "IPES", "blocks": 4, "isWholesaleHosted": false },
    { "carrier": "Onvoy",         "ocn": "637C", "ocnType": "CLEC", "blocks": 3, "isWholesaleHosted": true }
  ],
  "nxxSummary": {
    "totalBlocks": 11,
    "wholesaleBlocks": 7,
    "wholesaleShare": 0.64,
    "carrierCount": 3
  }
}

Field	What it tells you	Example
nxxSummary.totalBlocks	Blocks in the exchange (NPA-NXX)	11
nxxSummary.wholesaleBlocks	Blocks operated by wholesale or reseller carriers	3
nxxSummary.wholesaleShare	wholesaleBlocks / totalBlocks — share of the exchange on reseller infrastructure (0..1)	0.27
nxxSummary.carrierCount	Distinct carriers operating blocks in the exchange	3

Built for list-risk analysis

• Score lists by exchange wholesale share before spend
• Spot exchanges saturated with reseller inventory and route them to review
• Compare host-MNO vs enabling-carrier exposure across a campaign
• Audit suppression decisions with the full exchange context

When Extended is enough

• Per-number screening and routing → Extended Lookup (3 credits)
• High-volume validity checks → Standard (1 credit)
• Full Data earns its step when the question is about the exchange, not the number
• Block data still cannot name an MVNO brand per line — see the guide for the honest limits
