# Best Phone Verification Software - Page 2

*By [Neeraja Prakash](https://research.g2.com/insights/author/neeraja-prakash)*


Phone verification software helps businesses authenticate the phone numbers of customers or potential clients. Phone validation allows businesses to check phone numbers against a database to ensure that the phone number is in use, non-fraudulent, and can be used for business purposes.

Companies often need this software in an industry where phone numbers are commonly used, such as e-commerce, finance, marketing, telecommunications, and online services. These products offer a range of features, including number validation, carrier lookup, number formatting checks, country code validation, blacklist screening, and identification of phone types. Phone verification tools are typically used by sales, IT, customer service, and HR teams.

By employing various checks, organizations can effectively evaluate customer profiles, confirm identities, and thwart fraudulent activities. Phone verification software usually sources information from a CRM or internal database where personal data is stored. It uses automated SMS messages and voice calls to send one-time passwords (OTP) or verification codes to ensure ownership of the phone number.

This often happens when an employee wants to verify their customer has an actual phone number or if they need to collect a phone number for a [CRM platform](https://www.g2.com/categories/crm). This enhances security by ensuring that only legitimate users with access to the associated phone number can answer the phone and be considered customers, thus mitigating risks associated with fraudulent activities like fake accounts or unauthorized access.

Maintaining accurate customer data and facilitating secure communication channels between businesses and clients are imperative functions of this software, contributing to a safer and more trustworthy digital environment.

Phone verification tools are often implemented by the IT department to validate all phone numbers incoming to a company. Other products that help verify customer data include [email verification software](https://www.g2.com/categories/email-verification), which helps check for email usage, and [age verification software](https://www.g2.com/categories/age-verification), which ensures external clients are of an appropriate age for business. If an organization has data privacy authentication concerns, [identity verification software](https://www.g2.com/categories/identity-verification) helps verify in-person or online identities.

To qualify for inclusion in the Phone Verification category, a product must:

- Enable users to accurately verify phone numbers and user identities
- Send one-time passwords or codes via SMS or conduct a voice-based verifying process
- Notify users of fraudulent activity concerning customer phone number information
- Use or integrate with a CRM or internal database for sourcing phone data

### 9. [OptimalDial Answer Intent](https://www.g2.com/products/optimaldial-answer-intent/reviews)
OptimalDial Answer Intent is a phone intelligence solution that helps outbound sales teams identify which contacts on their call lists are likely to answer calls from unknown numbers before reps dial. It is designed for SDR teams, sales managers, and revenue operations professionals who rely on cold calling as a primary outreach channel and want to improve connect rates without changing their dialer or CRM. Sales teams typically see cold call connect rates between 3–5%. Answer Intent addresses this by analyzing the answering behavior of each phone number on a contact list, returning a prioritized list where each contact is labeled with a status based on real behavioral data. Contacts flagged as Likely Answer have demonstrated consistent patterns of picking up calls from unknown numbers and typically connect at 25–30%. Key features and capabilities: Answering behavior analysis: Each phone number is tested and analyzed to determine whether the contact is likely to answer, likely to go to voicemail, or has call screening enabled. Results are based on observed behavior, not predictive modeling or database lookups. Call screening detection: Identifies contacts with iOS Call Screening or Google Call Screen enabled, which affects an estimated 15–20% of mobile numbers. This allows teams to adjust their outreach strategy per contact. Mobile number verification: Carrier lookups filter out landlines, VOIP, and invalid numbers so reps only call verified mobile lines. CSV-based workflow: Users upload a contact list as a CSV from any data provider (Apollo, ZoomInfo, Cognism, Lusha, or others) and receive a labeled CSV back. Results can be imported into any dialer or CRM, including HubSpot, Salesforce, Outreach, and Salesloft. Contact prioritization statuses: Each contact is returned with one of four labels – Likely Answer, Likely Voicemail, Call Screening, or Not Mobile – giving reps a clear dialing order. Answer Intent currently supports US and Canada (+1) phone numbers. The product is dialer-agnostic and requires no integrations or workflow changes to implement. Teams can also use the status labels to route non-answering contacts to email or LinkedIn sequences for multi-channel coverage.

### 20. [VirtualSMS](https://www.g2.com/products/virtualsms/reviews)
VirtualSMS is an SMS verification API that provides phone numbers from 145+ countries for receiving OTP codes. The service uses real SIM-backed phone numbers rather than VoIP, enabling verification on services that reject VoIP numbers including WhatsApp Business, Telegram, banking applications, and dating platforms. The platform offers a REST API with OpenAPI 3.1 specification, webhooks for asynchronous event notifications, WebSocket for real-time SMS delivery, and a Model Context Protocol (MCP) server for integration with AI agents such as Claude, Cursor, and ChatGPT. A legacy compatibility endpoint at /stubs/handler\_api.php replicates the sms-activate API format, enabling migration from older providers without code changes beyond the base URL. Pricing is pay-per-use starting at $0.05 per OTP code, with no contracts, no minimum deposits, and automatic refunds on failed delivery. Payment options include credit cards, cryptocurrency (BEP20), and x402 stablecoin protocol on Base, Polygon, Arbitrum, and Optimism networks. Coverage includes 2,500+ services including WhatsApp, Telegram, Discord, Gmail, Snapchat, Tinder, banking applications, and e-commerce platforms. SDKs are available for PHP via Composer and a Node.js npm package for the MCP server. A free public price endpoint allows pricing queries without authentication.

### 21. [Voice CLI Verification](https://www.g2.com/products/voice-cli-verification/reviews)
SignalVerify Voice CLI Verification is a developer-friendly telecom testing tool that lets businesses verify exactly how their outbound voice calls appear to real customers across carriers and regions. Rather than relying on guesswork or synthetic testing environments, it uses a network of live SIMs and real devices to simulate actual call conditions — revealing whether your numbers are being labeled as "Spam Likely," mislabeled, or blocked before they ever reach your audience. Accessible directly from the command line or via API, it fits seamlessly into existing workflows and CI/CD pipelines, enabling engineering and operations teams to automate number identity checks, monitor call reputation across global markets, and fix trust issues proactively — all without needing to log into a dashboard.
