Fake Number Checker & Virtual Number Detector

To tell if a phone number is fake, look for these key indicators: VoIP carrier registration (Google Voice, TextNow), lack of digital footprint, multiple account usage patterns, and presence in fraud databases. Our fake number checker automatically analyzes all these signals.

Additionally, fake numbers often have short lifespans, unusual geographic mismatches, and appear on public SMS gateways. Our virtual number detector identifies these patterns instantly with over 99% accuracy.

Start with a live blacklist: we continuously monitor public SMS gateways and rental services to maintain an up‑to‑date list of virtual/disposable numbers commonly used to bypass verification.

On top of that, our virtual number checker/detector layers carrier type and allocation (NPA‑NXX) to confirm whether a number belongs to a VoIP operator and if the line type matches what it claims. Combined, these signals give you reliable, real‑time detection at onboarding.

Screen numbers before you send codes. Pre‑OTP checks block premium‑rate, disposable, and virtual numbers that drive SMS pumping.

Pair that with rate limits and simple anomaly alerts (spikes by IP/ASN or country prefix). NumCheckr’s phone intelligence helps you stop wasteful OTP sends while keeping good users moving.

A bot phone number check targets patterns automated signups rely on: public SMS inboxes, bulk VoIP allocations, and numbers reused across many accounts.

We combine number intelligence with velocity and repetition signals so you can challenge or block suspicious signups without adding friction for legitimate users.

Our fake phone number verification starts with a live disposable/virtual blacklist and layers carrier intelligence, HLR/line‑type checks, and allocation validation. It’s the same engine behind our fake number detector, designed for sub‑80ms decisions.

Beyond pass/fail, you get risk scoring, carrier and geography, and clear recommendations so you can auto‑block, step‑up, or allow based on policy.

Yes. Upload a CSV/Excel list to run a bulk fake number lookup. Results include whether each number is disposable/virtual, carrier type, and line status so you can quickly clean user databases or leads.

For continuous screening, you can also automate list checks via API on a schedule.

You can make 100 free fake number lookup requests monthly, 40,000 with the essential plan, and 500,000 with the premium plan. Each check includes virtual number detection and carrier analysis.

A fake number checker lets you instantly verify whether a phone number is real, disposable, or virtual during signup or support. Use it pre‑OTP to avoid sending codes to throwaway numbers and to keep onboarding clean.

A burner phone checker flags temporary or prepaid numbers commonly used for spam, trial abuse, and bot signups. Blocking them upfront reduces SMS costs and prevents low‑quality accounts from entering your system.

Yes. You can audit your database with a bulk fake number lookup (CSV/Excel or API) to find disposable/virtual numbers, update risk flags, and remove unreachable contacts from campaigns.
