You can work out your own number in two minutes.
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.

What is the best Twilio Lookup alternative?
1Lookup. Carrier and line type cost 1 credit, $0.0020 a number on the Enterprise plan against Twilio's flat $0.008, with a risk level on the same call. The same key carries 44 data products: email and IP validation, live HLR status, DNC and TCPA litigator scrub, reverse phone lookup, skip trace, and people, company and social data. It also ships an MCP server for AI agents and live Zapier, Make and n8n apps, and every plan starts with a 7-day free trial.
How is 1Lookup different from Twilio Lookup?
Twilio Lookup sells phone data as separate packages, each billed per request on the same number. 1Lookup charges one credit for carrier, line type and a risk level together, and the same credit balance covers 43 more data products, from email and IP checks to Do Not Call scrubs and company data. Twilio Lookup is phone only.
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. At 1,000,000 numbers a month, line type intelligence alone comes to $8,000. Prices read from Twilio's Lookup pricing page on 5 October 2026.
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.
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. Run the same records you send to Twilio Lookup today and compare the answers side by side.
Is Twilio Lookup worth it in 2026?
For carrier and line type at volume, 1Lookup costs less: $1,999 a month covers 1,000,000 lookups, where Twilio's Line Type Intelligence comes to $8,000 at its flat $0.008. Twilio Lookup fits teams that only need its free format check, or that want lookups on an existing Twilio bill. Its charges stack per signal (line type, line status, caller name and identity match are separate fees on the same number), Caller Name is US only, SIM swap and call forwarding need a sales conversation, and it does not check emails or IP addresses.
Teams switch from Twilio Lookup to 1Lookup for five reasons.
- $1,999 a month covers 1,000,000 lookups, where the same count of Twilio Line Type Intelligence requests is $8,000.
- 44 data products on one key: phone, email and IP checks, people, company and social data.
- Live HLR status, DNC and TCPA litigator scrub, reverse phone lookup and skip trace, with no second vendor.
- An MCP server for AI agents, and live Zapier, Make and n8n apps.
- No contract, and unused monthly credits roll over for 3 months.

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.
| Term | 1Lookup | Twilio Lookup |
|---|---|---|
| Minimum commitment | None. Monthly plans with no contract and no minimum volume; cancel any time | None published for Lookup; usage is pay-per-request with no included quota or minimum stated on the pricing page. Twilio Editions (Administration, Security, Enterprise) are quote-only via 'Contact sales'. |
| Going over your quota | — | Not applicable in the plan sense: every request is billed individually with no bundled allowance. Two packages use descending volume tiers rather than overage. Reassigned Number Risk: 0-1,000 $0.02, 1,000-10,000 $0.014, 10,000-50,000 $0.0125, 50,000-200,000 $0.0085, 200,000-500,000 $0.0075, 500,000-2,000,000 $0.003, 2,000,000-6,000,000 $0.0025, 6,000,000+ $0.0015.

| API access | Included on every plan and during the free trial; there is no tier that unlocks it | API access is the product and is self-service on a free trial account ('no credit card required to start'). Individual data packages are gated: Line Type Intelligence, Caller Name, SMS Pumping Risk and Line Status are self-service; SIM Swap and Call Forwarding are Private Beta requiring carrier approvals and a sales conversation; Identity Match and Reassigned Number require an access-request form. |
| Rate limit | 1,000 requests per minute on standard accounts, with higher limits available on request | — |
| Uptime SLA | — | 99.95% Monthly API Availability Percentage Threshold for the Services APIs, with a 10% service credit when missed. 99.99% applies only to customers holding Twilio Enterprise Edition (or Administration Edition purchased before 24 October 2024). Enterprise Edition itself describes this as '99.99% SLA Increase your SLA coverage from 99.95% to 99.99%'. |
| Compliance | — | The Trust Center names ISO/IEC 27001 and states there are 'regular external audits'. HIPAA is not general: 'HIPAA Accounts Build HIPAA compliant workflows' is listed as an Enterprise Edition feature. GDPR and CCPA are described as product capabilities rather than certifications. SOC 2 is not named on the pages that loaded; security and privacy documents must be requested. |
| Support | Starter: Email Support; Growth: Priority Email & Chat Support; Professional: Chat + Live Meeting; Enterprise: Dedicated CSM | Support is a paid add-on. Developer is free, web support only, 'Not eligible for guaranteed response time'.

Business is 'Greater of $1,500 minimum or 6% of monthly spend' with a technical account manager and 1 hour 24/7 critical response. Personalized is 'Greater of $5,000 minimum or 8% of monthly spend'. |
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.

Who this is for
A quick, honest read on which tool fits your use case.
Choose 1Lookup if: you want carrier and line type for $0.0020 a lookup at volume, with email and IP validation, live HLR status and DNC and litigator scrubs among 44 data products on the same key and credit balance.
Consider Twilio Lookup instead if: your team is already building on Twilio and wants phone intelligence inside that existing platform and billing.
