Frequently asked questions

Who is calling from this number? How do I know if it's spam?

The displayed spam score is calculated from reports made by users of the Saracroche app. The higher the score, the more likely the number is an unwanted call or a scam. To understand how these reports improve the results, see what number reporting is for.

Is Saracroche's reverse lookup really free and ad-free?

Yes. Unlike other services, Saracroche is 100% free, with no ads whatsoever, and its source code is open source. No personal data is collected: see our privacy policy.

What information do you get to identify a number?

Several pieces of data are displayed to find out who owns this number: the spam score and reports, the line type (landline, mobile, VoIP, premium rate), the carrier, the international prefix, the different number formats (E164, national, international), the points of interest associated via OpenStreetMap (shops, businesses), and the corresponding Saracroche block lists. See which numbers are blocked.

Where do the displayed reports come from?

Reports come from Saracroche app users who submit them when they receive an unwanted call. A number must exceed a certain report threshold before appearing as spam, to avoid false positives. Learn more about how reporting works.

Does this service replace the Saracroche app?

No, the reverse lookup is complementary to the app. It lets you check a number on a one-off basis. To automatically block unwanted calls, download the Saracroche app on Android or iOS.
