Numverify Validates Numbers.1Lookup Delivers Intelligence.
Numverify provides basic phone validation, but it stops at carrier lookup. 1Lookup is a phone intelligence platform that validates, analyzes fraud risk, provides HLR data, and delivers actionable insights. Built for businesses that need accuracy, speed, and depth.
Real-Time HLR Data
While Numverify only provides basic carrier information, 1Lookup includes real-time HLR (Home Location Register) data with every lookup. Get subscriber status, roaming information, and network intelligence that Numverify simply can't provide.
AI-Powered Fraud Detection
Numverify tells you if a number is valid. 1Lookup tells you if it's trustworthy. Our AI-powered fraud detection analyzes 150+ risk indicators to identify suspicious numbers, spam patterns, and potential fraud attempts.

Every lookup returns a risk signal, not just valid or invalid
A number can be perfectly well-formed and still be a burner, a VOIP line opened this morning, or a number other businesses have already reported. 1Lookup returns a risk score, a spam indicator and line type on the same call as the validation, so the decision to block, challenge or allow can be made in one request.

Instant fraud probability assessment for every number
Pattern Recognition

Example response
One credit balance
Every product below draws from the same credits, at $0.00200–$0.00495 per credit depending on plan.
- Phone validation1 credit
- Email verification1 credit
- IP intelligence1 credit
- Spam and risk score1 credit
Buy credits once, spend them on whatever you need to check
Most validation tools sell one channel, so a team checking phones, emails and IPs ends up with three vendors, three invoices and three unused balances. 1Lookup bills all of them from a single credit pool on a monthly plan, with no contract, and leftover credits carry into the next quarter instead of expiring at midnight.
Phone, email and IP on one API
One key, one balance, one integration
Phone data refreshed daily
From FCC and carrier sources
No contract
Monthly plans, with three-month credit rollover
A full line profile, not a status code
The same call returns HLR data, subscriber status, porting history, network type and roaming state. That is the difference between knowing a number is formatted correctly and knowing whether a message sent to it will arrive.

What migrating from Numverify actually involves
Both are REST APIs returning JSON, so the move is a URL, a key and a field mapping rather than a rewrite. The call above is the real shape of each request. Where the work usually goes is the response: our field names differ, and anything you were deriving from a status code may already be a field you can read directly.

numverify vs 1Lookup FAQ
Common questions about numverify and switching to 1Lookup
What is numverify?
numverify is a phone number validation and lookup API from apilayer. Given a phone number, it checks whether the number is valid and returns details such as country, carrier, line type (mobile or landline), and location. Developers typically use it to clean phone lists and confirm formatting before sending SMS or placing calls. It is delivered as a REST API with a free tier for low-volume testing.
How much does numverify cost?
numverify uses a tiered subscription model priced by how many validation requests you make each month, and it includes a free tier of 100 requests per month. As of publication, paid plans start around $14.99/month, with higher tiers unlocking larger monthly request allowances. Because pricing scales with volume, your actual cost depends on how many numbers you validate and which plan tier you choose, so confirm current rates on numverify’s pricing page before committing.
What is the best numverify 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 numverify?
numverify focuses specifically on phone number validation and carrier lookup, while 1Lookup unifies phone, email, and IP verification in one API backed by a single, shared credit pool. 1Lookup refreshes its underlying data daily from FCC and carrier sources and 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 several 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 numverify on real records rather than sample inputs.
Is numverify worth it in 2026?
numverify is worth it for high-volume format and carrier checks on a tight budget: the effective rate drops to about $0.52 per 1,000 validations on the $129.99/mo Professional Plus plan, coverage spans 232 countries, and the free tier of 100 requests per month has no time limit. Know what you are buying, though: validation is based on international numbering-plan and format databases, and the pricing page does not advertise live carrier or HLR checks of whether a number is currently active. Overage is also expensive relative to upgrading, at roughly $12 per 1,000 on the Standard plan versus about $3 per 1,000 in-quota, and the Platinum Support add-on comes pre-checked at checkout. If you need reachability signals or email and IP verification alongside phone, a multi-channel per-lookup API like 1Lookup covers those in one place.

Before you sign: Numverify (APILayer) 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 | Numverify (APILayer) |
|---|---|---|
| Minimum commitment | None. Monthly plans with no contract and no minimum volume; cancel any time | None published. Monthly or yearly billing, paid by credit card. 'You can initiate a cancellation or downgrade by selecting a new plan and providing at least one reason for your decision. The customer service team will cancel or downgrade your plan. Downgrades are not effective immediately; your platinum subscription will remain active until the end of the current billing period.' |
| Going over your quota | — | Billed per request past the monthly allowance rather than stopped: 'After reaching 100% of the allowance, overages fees will apply.' Rates are $0.0119920000 each on Basic, $0.0047992000 on Professional and $0.0020798400 on Enterprise. Users are notified by email and dashboard at 75%, 90% and 100% of allowance. The stated monthly volume excludes a '20% tolerance'. |
| API access | Included on every plan and during the free trial; there is no tier that unlocks it | API access on all tiers including Free, which allows 100 API requests per month. |
| Rate limit | 1,000 requests per minute on standard accounts, with higher limits available on request | No numeric rate limit published. The terms reserve a right to throttle: 'apilayer reserves the right to limit or throttle the number of network calls available to Your application(s) if apilayer (in its sole discretion) believes that such calls are being made for malicious reasons, or as the result of a technical error.' |
| Uptime SLA | — | No contractual SLA. The FAQ states 'our API's uptime is at around 99.9%' and 'At the current stage we are not offering any public statistics, but we will be happy to provide you with recent uptime reports'. |
| Support | Starter: Email Support; Growth: Priority Email & Chat Support; Professional: Chat + Live Meeting; Enterprise: Dedicated CSM | Free plan shows 'No Support'.
