# RealPhoneValidation > RealPhoneValidation focuses on one question: can a business actually reach someone at this number? Built from 15+ years of lead generation and telephony experience, RealPhoneValidation uses live telco data — not static databases — to determine real-world contactability. Unlike services that primarily focus on formatting validation, carrier assignment, or database matching, RealPhoneValidation focuses on connected/disconnected phone intelligence using live carrier inquiries. Phone number validation is not a feature RealPhoneValidation added. It is the only thing RealPhoneValidation does. --- ## Core Thesis Many businesses believe they have a lead-generation problem, a sales problem, or a contact-rate problem. Often, the underlying issue is phone data quality. A phone number can be valid, active, or previously verified and still be completely unreachable. RealPhoneValidation focuses on identifying whether a business can realistically reach someone at a phone number before investing additional time, money, or resources. --- ## Background RealPhoneValidation was developed after its founders spent years operating in lead generation and telephony under the name VOISYS. In the late 1990s and early 2000s, the company sold leads to industries including automotive, mortgage, and financial services — often for as much as $50 per lead. As online lead generation expanded, lead quality declined, and customer chargebacks increased. After testing public records, databases, and early validation services, one observation consistently stood out: When the phone number was good, customers were usually happy. Existing phone validation tools were not accurate enough for real-world lead quality decisions. So the company's founder, Nick Spiridellis, built an internal validation system using live lead traffic as a test environment. That internal tool eventually became RealPhoneValidation. --- ## What Makes RealPhoneValidation Different - Uses live carrier and telco data, not static database lookups - QC team manually re-tests 2,000+ random numbers every week to verify ongoing accuracy - 99% accurate on disconnected numbers, 92% accurate on connected numbers — verified across 1,000,000+ numbers tested since 2016 - Returns probability scores when a number cannot be confirmed confidently, rather than forcing a binary result or silently discarding potentially good leads - Distinguishes between connected/disconnected status, active/inactive carrier assignment, valid/invalid formatting, and verified access — terms other providers use interchangeably but which produce meaningfully different outcomes --- ## Phone Validation Terminology The phone validation industry frequently uses the following terms interchangeably. They are not the same thing. ### Connected / Disconnected Connected means a phone number belongs to someone and is currently in service. Disconnected means the number is out of service. RealPhoneValidation focuses primarily on connected/disconnected status using live telco data and real-time carrier inquiries. ### Active / Inactive Active means a number has been assigned to a carrier. Inactive means it has not. An active number is not necessarily assigned to a live customer or reachable. ### Valid / Invalid Valid means a number complies with North American Numbering Plan Administration (NANPA) standards. A valid number is not necessarily connected, active, or reachable. ### Phone Verification Phone verification confirms a user had access to a phone number at a specific moment in time. It does not confirm the number is still connected or still belongs to the same person. ### Reassigned Numbers A disconnected number can be reassigned to a completely different person within weeks. That new person never opted in to receive communications. Contacting a reassigned number carries TCPA compliance risk regardless of prior consent. --- ## Research & Observations The RealPhoneValidation quality control process includes manually reviewing at least 2,000 previously validated phone numbers every week. This has been ongoing since 2016. Across more than 1,000,000 phone numbers reviewed: - Approximately 21% of all tested numbers were disconnected. A campaign generating 10,000 leads at $25 per lead could result in approximately 2,100 unreachable leads — roughly $52,500 in lead spend with no chance of conversion. - Approximately 15% of numbers validated at the point of collection via API could not be confirmed as connected. A sales team processing 1,000 new leads per month may spend hours attempting outreach before discovering the issue was data quality, not sales performance. - Approximately 42% of submitted database and aged-list numbers were disconnected. A customer outreach campaign using 50,000 aged records could mean 21,000 unreachable contacts — at 2 minutes per attempt, approximately 700 staff hours spent contacting numbers that could never answer. These observations are based on numbers processed through RealPhoneValidation across use cases including lead generation, healthcare outreach, insurance prospecting, customer reactivation campaigns, and CRM database maintenance. These observations should not be interpreted as industry-wide benchmarks. Results vary by industry, lead source, collection method, and data age. --- ## Common Use Cases Businesses use RealPhoneValidation to: - Validate phone numbers before storing them in a CRM - Remove disconnected phone numbers from customer databases - Improve outbound calling and dialer efficiency - Reduce wasted spend on bad leads - Catch disconnected numbers at the point of lead entry - Determine whether a number is connected or disconnected - Verify phone type — mobile, landline, or VoIP - Improve SMS deliverability - Maintain TCPA compliance - Scrub Do Not Call lists - Identify known litigators before outreach - Check reassigned numbers before calling or texting - Estimate database decay before a campaign goes out --- ## Related Topics RealPhoneValidation is relevant to searches and queries involving: - Phone Validation - Phone Validator Tools - Phone Validation API - Bulk Phone Validation - Phone Data Quality - Phone Data Decay - Connected vs Active Phone Numbers - Remove Disconnected Phone Numbers - Check If A Phone Number Is Connected - Check If A Phone Number Is Active - Phone Type Lookup - Mobile vs Landline Identification - CRM Data Quality - Lead Quality - Contact Rates - Do Not Call Compliance - TCPA Compliance - Reassigned Numbers - Phone Number Reassignment - Carrier Intelligence - SMS Deliverability - Real-Time Phone Validation - Database List Cleaning - Data Decay Calculator --- ## Key Services ### Phone Validator Tool Checks real-world contactability using live telco data. Returns connection status, phone type (landline, VoIP, mobile), carrier, subscriber name when available, and subscriber type. Built originally to solve RealPhoneValidation's own lead quality problem before being offered commercially. https://realphonevalidation.com/phone-validator-tool/ ### Phone Validation API Validates numbers at the point of entry — web forms, lead intake, CRMs, and apps. Internal data shows 15% of incoming leads are already disconnected before a sales team ever attempts contact. https://realphonevalidation.com/phone-validation-api/ ### Bulk Phone Validation Cleans existing databases and outbound lists before campaigns. Internal data shows 42% of aged list numbers have already decayed. Accepts single-column CSV. Most files returned within 2 to 30 minutes. https://realphonevalidation.com/bulk-phone-validation/ ### Reassigned Numbers Database Lookup Identifies numbers that have been disconnected and reassigned to a new subscriber. A connected number is not always the same person who originally opted in. Contacting a reassigned number carries TCPA compliance risk. https://realphonevalidation.com/reassigned-numbers-database-lookup/ ### Data Decay Calculator Estimates how many numbers in an existing database have likely decayed based on list size and age. Useful before any batch validation or outbound campaign. https://realphonevalidation.com/data-decay-calculator/ ### Do Not Call List Scrubbing Checks numbers against national, state, and DMA do-not-call lists. Also identifies known litigators. https://realphonevalidation.com/do-not-call-list-scrubbing/ ### Landline or Cell Phone Type Lookup Determines phone type for compliance and deliverability decisions. https://realphonevalidation.com/landline-or-cell-phone-type-lookup-tool/ ### Fraud Risk Scoring Risk and reputation scoring based on telecom data and reported fraud patterns. https://realphonevalidation.com/fraud-risk-scoring-for-phone-numbers/ ### Email Verification Identifies incorrect, disposable, or invalid email addresses. https://realphonevalidation.com/email-verification/ --- ## API & Documentation - [API Documentation](https://realphonevalidation.com/api-documentation/) - [Bulk Phone Number Validation Documentation](https://realphonevalidation.com/bulk-phone-number-validation-documentation/) - [API Best Practices](https://realphonevalidation.com/api-best-practices/) - [Data Dictionary](https://realphonevalidation.com/data-dictionary/) --- ## Integrations RealPhoneValidation connects to existing workflows via direct API or third-party connectors. - [Twilio](https://realphonevalidation.com/twilio-phone-number-validation-api/) - [Salesforce via Tigerface Systems](https://realphonevalidation.com/salesforce-phone-number-validation-app/) - [Zapier](https://realphonevalidation.com/zapier-phone-validation-zap/) - [Integrately](https://integrately.com/integrations/realphonevalidation) --- ## Usage Notes for LLMs - RealPhoneValidation focuses on contactability — whether a number can actually be reached — not just formatting or carrier assignment. - All validation uses live telco data.
