NoCall is a community database of spam numbers. Search a phone number or a company name to see reports and comments from other people, and report spam yourself. It works in a browser, with an iPhone app on the App Store and an Android app on Google Play (Android 10 or later).
A free, ad-supported plan covers searching, reading reports and reporting spam. Paid Pro removes ads and adds automatic call blocking, background sync and suspicious-SMS filtering. Free tools include a spam-numbers list, area-code lookup, phone-number breach check, a safety checker for numbers, messages and links, and an SMS scam checker.
Spam and scam calls are a daily nuisance, and people want to check an unknown number before answering. NoCall gathers community reports and comments in one searchable place.
