Each unique phone number you search counts as one lookup. Searching the same number multiple times within 24 hours only counts once, so you can re-check numbers without using additional lookups.

We use real-time carrier data and multiple spam databases to provide the most accurate information possible. Carrier and location data is typically 99%+ accurate. Caller ID names depend on the number being registered with a name in carrier databases.

WSTTM supports all US phone numbers including landlines, mobile phones, and VoIP numbers. International numbers are not currently supported but may be added in the future.

Lookups reset at the beginning of each billing cycle and do not roll over. Make sure to use them before your renewal date! If you consistently need more lookups, consider upgrading to a higher plan.

Yes! You can change your plan at any time from your billing settings. When upgrading, you'll be prorated for the remainder of your billing cycle. Downgrades take effect at the next billing date.

The watchlist lets you save phone numbers you want to monitor. You can add notes to each number and quickly reference them later. It's perfect for tracking suspicious callers or keeping a list of numbers you've researched.

After looking up a number, you'll see a "Report Spam" button on the results page. Click it, select the type of spam (robocall, scam, telemarketer, etc.), and submit. Your report helps our community by improving spam detection for everyone.

Yes! We take privacy seriously. Your lookup history is private and only visible to you. We use industry-standard encryption (SSL/TLS) for all data transmission. We never sell your personal information or lookup data to third parties.

You can cancel anytime from your billing settings page. Your subscription will remain active until the end of your current billing period. After cancellation, your account will revert to the free plan with 3 lookups per month.
