Twilio Lookup Pricing,Package by Package.
Twilio does not sell “a lookup”. Formatting and validation are free, and every useful signal after that is a separate per-request package that stacks on the same number: line type at $0.008, line status from $0.007, caller name at $0.01, identity match at $0.10. Full rate card below, read off Twilio’s own pricing page on 18 August 2026.
1Lookup prices one credit per lookup, $0.00495 on the entry plan down to about $0.002 at the top, and returns line type, carrier, reachability and a fraud score on that one call. Which is cheaper depends entirely on how many packages you would have stacked, so the rate card comes before the pitch.
Feature Comparison
Detailed comparison of phone validation capabilities
| Feature | 1Lookup | Twilio Lookup | Winner |
|---|---|---|---|
Format and validity check Confirming a number is well formed and dialable | 1 credit, $0.002 to $0.005 by plan | Free, no published cap | Twilio |
Carrier and line type Mobile, landline or VoIP, and which network owns the number | Returned on the same lookup, no extra charge | $0.008 per request (Line Type Intelligence) | 1Lookup |
Live reachability Whether the line is currently active rather than merely valid | Real-time HLR data on the same lookup | $0.007 per query, falling to $0.00385 above 10M (Line Status) | 1Lookup |
Fraud signals Both ship fraud signals. Twilio prices them as separate packages | Fraud score returned with every lookup | SMS Pumping Risk Score free in North America, $0.025 elsewhere; SIM swap is contact sales | Draw |
Email and IP validation Whether one vendor covers all three or you buy three | Same API key, same credit balance | Not part of Lookup, which is phone only | 1Lookup |
What Twilio Lookup costs
Pay as you go against your Twilio account balance, with no subscription and no minimum. The catch is not the unit price, it is that the packages are independent: asking one number for its line type, its live status and its caller name bills three times.

Working out your own number
The honest way to compare is to count the packages you would actually call. Run a number through the free carrier lookup and the free HLR lookup to see which fields you care about, then put your monthly volume through the phone validation cost calculator and check it against 1Lookup’s per-credit rates. If you are also pricing a broader contact-data suite rather than a phone API, we published the same kind of rate card for Melissa, whose credit model charges 10 credits for a live phone check.

Twilio Lookup vs 1Lookup FAQ
Common questions about Twilio Lookup and switching to 1Lookup
What is Twilio Lookup?
Twilio Lookup is a phone number validation and intelligence API from Twilio. It confirms that a number is correctly formatted and returns it in standardized E.164 and national formats, and it can enrich that number with premium data packages such as line type intelligence, caller name, SIM swap, call forwarding, and SMS pumping risk. Developers typically use it to clean phone lists, route messages correctly, and reduce fraud before sending SMS or placing calls.
How much does Twilio Lookup cost?
Twilio Lookup is pay as you go against your Twilio balance, with no subscription and no minimum. Formatting and validation are free. After that you pay per data package: line type intelligence $0.008 per request, line status from $0.007 per query down to $0.00385 above 10 million, inbound caller identification $0.01 per request (US only), identity match $0.10 per request with prices varying by country, and reassigned number risk from $0.02 down to $0.0015 across eight volume tiers. SMS Pumping Risk Score is free for North American numbers and $0.025 per request elsewhere, and SIM swap and call forwarding are contact sales with no published price. The packages are independent, so asking one number for its line type, its live status and its caller name bills three times. Prices read from twilio.com/en-us/lookup/pricing on 18 August 2026.
What is the best Twilio Lookup alternative?
The best alternative depends on what you actually need to verify. If you only validate phone numbers, several APIs compete on price and country coverage; if you also verify emails and IP addresses, 1Lookup is a strong option because it handles phone, email, and IP validation through a single API and one universal credit system. It also offers carrier and HLR lookup, reverse lookup, and fraud and IP intelligence, plus a free trial so you can test it against your own data before switching.
How is 1Lookup different from Twilio Lookup?
Twilio Lookup is centered on phone number data, while 1Lookup unifies phone, email, and IP verification in one API that draws on a single, shared credit pool. 1Lookup draws its underlying data from FCC and carrier sources, and it adds carrier/HLR lookup, reverse lookup, and fraud and IP intelligence within the same platform. For teams that would rather use one vendor and one credit balance across multiple verification types, that consolidation is the main practical difference.
Can I try 1Lookup for free?
Yes. 1Lookup offers a 7-day free trial so you can validate your own phone numbers, emails, and IP addresses before committing to a plan. This lets you compare coverage and data quality against Twilio Lookup on real records rather than sample inputs.
Is Twilio Lookup worth it in 2026?
Twilio Lookup is worth it for teams already building on Twilio: basic formatting and validation lookups are free, SMS Pumping Risk Score is free for North American numbers, and you pay only for the intelligence packages you request, like Line Type Intelligence at $0.008 per request. The catch is how charges accumulate: each signal (line type, line status, caller name, identity match) is a separate per-request fee on the same number, and key packages are geographically restricted, with Caller Name US-only and Call Forwarding UK-only. SIM swap and call forwarding pricing is not self-serve and requires contacting sales. It is also phone-only, so teams that verify emails and IPs too often prefer a multi-channel per-lookup API like 1Lookup with one balance across all three.
One credit instead of three packages
If all you need is a format check, Twilio does it for nothing and you should use Twilio. If you need line type, reachability and a fraud signal on the same number, those are three separately billed Twilio packages and one 1Lookup credit.

The same month, priced both ways
Pick one of Twilio Lookup’s own published volumes. Their figure is their published price at that tier; ours is the cheapest plan on our rate card that covers it. Nothing here is interpolated.
1Lookup
$99/mo
The Starter plan, 20,000 credits a month at $4.95 per 1,000. Using 10,000 of them is 50% of the plan, so $9.90 per 1,000 effective.
Twilio Lookup
$80
Their published price for “10,000 Line Type Intelligence lookups”, at $8 per 1,000.
At 10,000 a month, Twilio Lookup is $19 cheaper. Our smallest plan that covers this volume includes 20,000 credits, so the gap closes as you use more of it.

Before you sign: Twilio Lookup and 1Lookup on the operational terms
The terms that decide what a year actually costs, rather than what the first month does. A blank means we could not verify it on either product’s published pages, not that the answer is nothing.

Twilio Lookup fine print worth reading twice
Published terms that change what Twilio Lookup costs or what you can do with it. Each one links to the Twilio Lookup page it was read on, because a claim about somebody else’s contract should be checkable in one click.
Any guaranteed support response time is a paid add-on priced at the greater of a $250 monthly minimum or 4% of monthly spend for the Production plan, rising to $1,500 or 6% for Business and $5,000 or 8% for Personalized.

What you actually work in
Twilio Lookup is a a screenshot of the Lookup web app: country-flag phone number input, checkboxes for the data packages (Validation and Formatting [free], Line Type Intelligence, Caller Name, SMS Pumping Risk, SIM Swap, Call Forwarding, Line Status), a Lookup button, and the JSON response body rendered below product you log into. 1Lookup is an API and a dashboard you mostly do not log into: you call it from the system that already has the record. Which of those you want is usually the whole decision, so here is theirs.

- Part of the Twilio ecosystem (Verify, SMS, Voice) at large scale - Twilio cites 5.1B+ user validations per year - so lookups integrate directly into existing messaging/2FA flows
Where 1Lookup wins
- Phone, email, and IP validation in one API with one universal credit balance
- Phone data refreshed daily from FCC and carrier sources
- Carrier/HLR lookup, line type, spam score, and reverse lookup included alongside validation

Who this is for
A quick, honest read on which tool fits your use case.
Choose 1Lookup if: you want phone, email, and IP validation together under one universal credit system, rather than phone data alone billed per add-on package.
Consider Twilio Lookup instead if: your team is already building on Twilio and wants phone intelligence inside that existing platform and billing.
