The lede

Compare NPANXX rate decks, catch the margin a partner is quietly cherry-picking, and reprice down to the NPA in minutes, not a day in Excel. LERG-enriched, jurisdiction-aware, and local-first.

"Drop in two decks — see where you win and where they beat you, in seconds."

Section II — What this replaces

Right now, this lives
in a spreadsheet.

A full US NPANXX deck runs 200,000 rows. Here's what that costs you every time a new one lands.

01

The deck outgrows the spreadsheet

Pivot tables crawl and formulas break long before 200k rows — so you spot-check a few NPAs and trust the rest is fine.

02

Margin leaks out of sight

A partner re-routes traffic to the NPANXX where your margin is thinnest. The loss is real, and buried across thousands of rows until the invoice lands.

03

Jurisdiction is invisible in a CSV

Interstate, intrastate, indeterminate — every NPANXX prices differently, and none of that context lives in your sheet, so mispricing slips through.

You don't need a faster spreadsheet. You need to see the deck for what it is.

Section III — Two sides to every deckAnalyze · Adjust
Section III-A

Analyze

Compare two NPANXX decks side-by-side and see what is hiding between them.

Code Reports

Coverage gaps and LERG coverage — see exactly which NPANXX a deck is missing, and where the other one has you covered.

Pricing Reports

Rate differences by state, NPA, or individual NPANXX — split by interstate, intrastate, and indeterminate jurisdiction.

Section III-B

Adjust

Reprice or build a deck, down to the code — without the spreadsheet gymnastics.

Granular reprice

Adjust by %, fixed amount, a single NPANXX, every NPA in a state, or a metro area by population.

Effective dates & export

Build a new deck, set effective dates, and export switch-ready — plus downloadable comparison reports.

Section III-C — Five decks into oneCompose · blend & generate
Section III-C

Compose

Blend up to five carrier decks into one — least-cost and jurisdiction-aware, in seconds.

Least-cost routing

Pick the cheapest, the Nth-cheapest, or a blend of the top N — chosen independently for interstate, intrastate, and indeterminate.

Simulate, then generate

Compare strategy scenarios against a sample before you commit, then generate a switch-ready deck plus a route-distribution map and a build summary.

Section IV — How it works3 steps · no spreadsheet

Three steps. No spreadsheet.

01

Drop in your decks

CSV or Excel NPANXX decks. Parsing runs in your browser — no server, no upload.

02

See what is hidden

Every NPANXX is enriched with LERG and split by jurisdiction — interstate, intrastate, and indeterminate.

03

Adjust & export

Reprice by NPA, state, metro, or NXX, set an effective date, and export a switch-ready sheet plus a report.

Section V — Why it existsBuilt by an operator
Colophon

One operator. Two evenings. The question Excel couldn't answer in a day.


There wasn't anything else that did it — so now it's yours too, free. No tiers, no upsells, no telemetry.

A partner sends a new rate deck — or quietly cherry-picks the traffic to where your margin is thinnest. The answer is buried in +200k rows. We surface it in minutes, down to the NPA, so you respond surgically instead of rebuilding a deck.
