Phone Number Validator Lookup

Verify Phone Numbers And Check Line Type & Carrier

Use the IPQS free phone validation tool to verify phone numbers with 99.9% accuracy. Lookup any phone number with international phone validation that enables worldwide coverage. Retrieve important phone number reputation data points such as risk scoring, carrier name, line type (VOIP, landline, cellular), or status as a disposable phone number. Our algorithms are also intelligent enough to automatically parse the country code associated with the phone number.

Upon performing a phone validation check, the phone reputation is also searched against abuse reports, spam, and reputation history across the IPQS threat network. Numbers associated with recent account sign up fraud are automatically blacklisted.

Integrate Phone Validation by API or Upload a Bulk CSV List

Validating phone numbers for registrations, payments, marketing lists, and overall user verification (such as AML/KYC) is an industry best practice to ensure your user data is accurate and up to date. Phone number verification also has an added benefit of limiting abusive behavior such as fake duplicate accounts and abuse from credit card chargebacks.

Verifying phone numbers can be performed with the IPQS phone number validation API which includes example code to make integration a breeze. Bulk marketing lists can also be uploaded through the user dashboard in CSV format. Affordable pricing and enhanced lookup details provide better data and reputation insight than similar services.

Detect disconnected phone numbers and check if a phone number is currently active, all with one simple API lookup. Improve user data and lead quality with accurate phone number lookups that check carrier and prepaid status. Identify if the phone number line type is a landline, mobile/cellular, or VOIP.

Learn about IPQS Phone Validation

How Does Phone Number Validation Work?

Upon searching with the phone number validator tool above, IPQS will automatically lookup the number against the country's number routing rules. A quick syntax check is performed to ensure the phone number is properly formatted and then matched against active line types. Once a match is found, the carrier details are retrieved and further analysis can be performed. Using data directly from the carrier, subscriber information and line status can be identified. At this point, it's possible to determine if the phone number is actively connected or has been recently disconnected. Additional phone number reputation checks are performed to analyze abusive history or activity as a temporary and disposable phone number.

Using these services in real time to verify phone numbers is a great way to analyze user quality or perform lead scoring. This can be taken a step further for additional reputation checks with email address validation and proxy and VPN detection, for complete user verification.

What Phone Validation Lookup Data Is Available?

Using either the phone verification API or bulk list processing will return the number's associated country, associated country dialing code, carrier name, line type, prepaid status, risk scoring, and overall validity as true or false. This makes it easy to identify invalid or disconnected phone numbers that likely represent a fraudulent user. This data is available across all regions, so all countries are fully supported with great coverage rates. Geographic data can also be supplied such as city, state, region, and country.

Lookup Any Phone Number, Check Active Landline, Wireless, or VOIP Line Type

Line type detection and carrier lookup details with phone number verification can provide insight into the true quality of the user. Some carriers, especially among ported numbers or prepaid plans, can represent higher risk. VOIP numbers are inherently riskier than wireless/cellular and landline numbers. Millions of individual phone numbers are also blacklisted by IPQS due to excessive abuse, spam calls, and suspicious behavior patterns.

HLR, LRN, & Carrier Lookups

For most advanced telecom and voice users that want to verify phone numbers, we recommend our HLR & LRN data that can provide direct carrier details for number routing. Carrier and line type details even for ported numbers are fully available for most countries. More advanced data is available on request, so please contact our support team to learn more.

Check If Phone Number Is Still Active?

To check if a phone number is real or still in service, use the phone number lookup tool above. If the valid phone number field displays "true", then the number is reachable and currently active. These statuses can frequently change due to number porting. VOIP phone numbers carry a greater risk for disconnections or being directed to a voicemail greeting.
