Email and phone intelligence services provide context about contact points that can support identity, fraud, onboarding, and account protection decisions.
How the risk develops
Email and phone fraud uses weak or compromised contact points to create trust, intercept authentication, or connect an attacker to a valuable account.
Fraudsters may use disposable email, virtual numbers, recycled phone numbers, newly registered domains, stolen mailboxes, or a number obtained through a SIM swap.
The same phone, mailbox, device, or recovery address may appear across applications and accounts even when each profile uses a different name.
The attacker intercepts one-time codes, persuades support staff, resets a password, verifies a new account, or uses the contact point to make a synthetic identity seem established.
Once the contact channel is trusted, the fraudster can take over an account, redirect notifications, approve transactions, or build credibility for later abuse.

Email & Phone Intelligence
Email Risk Intelligence for Fraud Prevention
Emailage (acquired by LexisNexis) is the global leader in email-based fraud risk intelligence. By analyzing an email address against 50+ signals — domain age, syntax patterns, breach history, social media presence, and transaction history across a network of 4,000+ companies — Emailage returns a real-time risk score for each email without requiring any additional customer data.
Email & Phone Intelligence
Phone Intelligence & Communication-based Identity
Telesign provides communication-based identity intelligence using phone numbers as a trust anchor. Their Phone ID product analyzes phone numbers in real-time to assess account risk, detect SIM swaps, identify VoIP numbers, and verify phone number-to-identity binding. Telesign also provides OTP SMS/voice delivery with fraud-resistant channel selection.
Email & Phone Intelligence
Phone Number Intelligence & Verification
Twilio Lookup provides real-time phone number intelligence for fraud prevention and identity verification. Their API returns carrier data, line type (mobile, landline, VoIP), number validity, caller name, SIM swap history, and risk scores — enabling developers to assess phone number risk in real-time during registration, login, and payment flows.
Email & Phone Intelligence
Multi-Channel Fraud Intelligence for Email, Phone, IP, and Device
IPQualityScore (IPQS) is a multi-channel fraud intelligence platform that enables businesses to assess risk signals across email addresses, phone numbers, IP addresses, and device fingerprints in a single API call. Unlike vendors focused on a single signal type, IPQS aggregates real-time fraud data across channels to provide a composite risk score — making it particularly powerful for identifying synthetic identities, bot traffic, and account fraud at the point of onboarding or transaction. IPQS maintains a live database of fraudulent email addresses, disposable domains, proxy/VPN IPs, high-risk phone numbers, and compromised accounts — updated continuously from its global network of data partnerships. With competitive pricing and a developer-first integration experience, IPQS has become a popular fraud enrichment layer for growth-stage fintechs and e-commerce companies.
Email & Phone Intelligence
Phone Intelligence and Identity Resolution at Scale
Neustar, now part of TransUnion following a $3.1 billion acquisition in 2021, is a leader in phone intelligence, identity resolution, and real-time risk data. Neustar's OneID platform links phone numbers to identity records, enabling organisations to validate caller identity, detect spoofed calls, and assess the risk of a phone number at the point of interaction. In the fraud context, Neustar's phone intelligence data is used to detect synthetic identities, identify stolen credentials, and flag suspicious account creation attempts. Its Trusted Call Solutions help financial institutions validate inbound callers before routing to agents — reducing call centre fraud and social engineering attacks. Backed by TransUnion's vast credit and identity data assets, Neustar now offers a more comprehensive identity intelligence layer than most pure-play phone intelligence vendors.
Evaluation guide
Use the public directory as a starting point, then verify current facts, fit, and obligations with each provider and your internal stakeholders.
Specify the contact attributes, countries, carrier or mailbox coverage, and decision points that matter to your program.
Ask how stale, recycled, shared, virtual, or newly created contact points are represented and explained.
Review how these signals combine with identity, device, transaction, and customer-provided data.
Validate privacy, lawful-use requirements, latency, data provenance, retention, and operational fallback paths.
Open Vendor Scan when you are ready to work through your institution context, control needs, payment rails, and existing stack. This public page does not expose personalized outputs.
