API Format: REST and GraphQL vs REST-Only
Twilio Lookup is a REST-only API. Each data type — LRN, CNAM, carrier — is a separate endpoint call. Fetching LRN and carrier data for the same number means two round trips, two billing events, and two failure modes to handle. At high query rates, that overhead compounds: double the latency budgets, double the retry logic, double the response parsing.
VeriRoute offers both a REST endpoint and a GraphQL endpoint. The GraphQL interface allows you to specify exactly which fields to return in a single query. More practically: VRI's combined LRN + Carrier endpoint returns both data types in a single API call at $0.0014 total — less than the cost of a single LRN lookup from Twilio.
Both VRI endpoints use standard Bearer token authentication. Existing Twilio Lookup integrations can migrate to VRI by updating the endpoint URL, swapping the API key, and remapping the response fields — a change typically completed in hours, not days.
VRI-Exclusive Features
Messaging Provider Identification
Messaging provider identification returns the actual messaging platform routing traffic on a given number — not the underlying LEC carrier, but the application-layer messaging provider handling the traffic. For A2P SMS compliance, this is the operative data point. TCPA consent obligations, 10DLC registration requirements, and sender verification workflows all attach to the messaging provider, not the carrier.
Twilio does not offer this data type at any price. Teams that benefit most:
- SMS aggregators validating sender compliance before onboarding new customers
- CPaaS providers building A2P compliance tooling for enterprise customers
- Contact centers confirming numbers target the correct messaging path
- Enterprise A2P senders auditing number lists for 10DLC routing accuracy
At $0.0009 per lookup, a full compliance scrub of 1 million numbers costs $900.
LRN activated_at Timestamp
Every LRN response from VRI includes an activated_at field: the date the LRN was last activated on
its current routing path. This timestamp is a direct port recency indicator.
In fraud prevention workflows, recent port activity on a number is a well-established risk signal. Twilio Lookup
does not return this field. No other major lookup provider exposes it as a standard response field. For fraud
teams building behavioral risk models or SIM-swap detection layers, activated_at is a direct feature
that requires no downstream enrichment and comes back in the standard LRN response.
List Cleaning Before Billing
VRI validates every number in a batch before executing the lookup and billing for it. Malformed, non-dialable, or otherwise invalid numbers are filtered before the query runs. You are only billed for lookups that return meaningful data.
On a list of 10 million numbers with 10% invalid entries, VRI's list cleaning eliminates 1 million billed lookups before the first response payload is processed. That is $500 in direct savings on LRN lookups alone — on a single batch.
Who Should Use VRI vs Twilio?
VRI is the better choice when:
- You are running high-volume LRN lookups and per-lookup unit economics are a real budget consideration. At $0.0005 vs $0.005, the breakeven on any switching effort is reached in the first month at moderate volume.
- You need messaging provider identification for A2P compliance, 10DLC audit workflows, or sender verification. This is a hard capability gap — Twilio cannot provide this data.
- Your fraud stack requires port recency data as a behavioral risk signal.
activated_atis available on every VRI LRN response; there is no equivalent in Twilio Lookup. - You are cleaning large number lists and want to avoid paying for invalid numbers.
- You prefer a no-commitment, pay-as-you-go billing model with no minimum commit.
- You are building on GraphQL infrastructure and want field-level query control.
Twilio Lookup may be the stronger choice when:
- Your team is operating deeply within the Twilio platform and consolidated billing across all Twilio products is the primary decision driver.
- You are running low-volume, one-off lookups where the total monthly spend is small enough that per-unit differences are noise.
- Your primary use case is CNAM enrichment at low volume — Twilio's CNAM pricing is slightly more competitive for that specific data type at low volumes.
Frequently Asked Questions
Is VRI's phone number lookup API compatible with existing Twilio integrations?
VRI uses standard REST endpoints with Bearer token authentication — the same pattern as Twilio Lookup. Migrating is a matter of updating the endpoint URL, swapping the API key, and remapping the response fields in your existing code. No architectural changes are required. VRI's documentation includes a migration reference for teams moving from Twilio Lookup specifically.
How much cheaper is VRI LRN lookup vs Twilio Lookup?
VRI Enhanced LRN is priced at $0.0005 per lookup; Twilio Lookup is approximately $0.005. That is a 10× difference on the same data type. At 10 million monthly LRN lookups, VRI costs $5,000 versus Twilio's $50,000 — a $45,000 monthly delta before any volume discounts on either platform.
Does VRI offer messaging provider identification like Twilio?
Twilio does not offer messaging provider identification. VRI does, at $0.0009 per lookup. It returns the messaging platform routing traffic on a given number, which is the relevant compliance data point for A2P sender verification, 10DLC audits, and SMS aggregator onboarding workflows.
Can I migrate from Twilio Lookup to VRI without a long-term contract?
Yes. VRI has no minimum commitment and no contract requirement. The free tier includes 10 free lookups with no credit card required, which is enough to run a proof of concept against a real number sample before committing any spend.
What is the difference between LRN and Carrier lookup across VRI vs Twilio?
LRN (Local Routing Number) lookup identifies where a number currently routes, including after porting — it reflects the number's live routing state, not its original provisioning. Carrier lookup identifies the network carrier associated with the number's original assignment. VRI's combined LRN + Carrier endpoint returns both in a single API call for $0.0014. Twilio offers both but as separate lookups billed individually, so combined retrieval requires two API calls.
