Identify or block unwanted callers
Use the iOS Call Directory extension to identify reported spam calls or block unwanted callers through the app's protection mode.
Phone lookup and report community
Lookup and report unknown phone numbers
Roblock helps people identify spam, fraud, telemarketing, robocalls, and other unwanted callers through community reports.

Web lookup plus app protection
iPhone app protection
Roblock is more than a lookup page
The web lookup helps you check a visible number before calling back. The iPhone app works with supported iOS call, message-filtering, and reporting extensions. Read the Roblock iPhone guide for the setup choices and limits.
Apply configured message rules
Enable the Roblock Message Filter extension to let its configured local phrase rules help sort some unwanted messages.
Report from Phone and Messages
After selecting Roblock for SMS/Call Reporting, you can report unwanted calls from Recents and messages from the Messages app when iOS offers the report action.
Choose identification or blocking
Some people want a visible warning before answering. Others prefer direct blocking. Roblock is designed around that choice.
Finish the local list update
After enabling the call extension, open Roblock and allow its locally stored Call Directory list to finish updating.
Use an optional nearby-number range
Roblock can build a local protected range with a nearby-looking prefix. A range match does not prove that an individual caller ID was spoofed.
Protection signals
What Roblock protection is built from
Roblock combines a locally stored Call Directory list, community reports, FCC complaint signals, and supported iOS extensions. These are directional trust signals, not a promise that every unwanted call or text can be stopped.
The enabled extension loads Roblock's locally stored list into the supported iOS call flow.
Choose whether Roblock identifies listed calls or blocks them; only the selected mode is loaded.
Roblock may show community reports and FCC complaint signals as context, not verified findings about a caller.
Roblock supports unwanted call and message reporting paths from iOS.
Careful reporting
Keep sensitive details out of reports
Roblock works with supported iOS extensions and user-submitted reports. Keep descriptions short and focused on the unwanted behavior; do not submit private account, payment, health, address, authentication, or message details.
Read Privacy PolicyUse the report category
Choose the closest available category instead of adding unnecessary personal context.
iOS handles call blocking
The Call Directory extension works from a local block list on the device. Incoming call handling is controlled by iOS.
Reports should avoid private content
When adding context to a report, do not include passwords, account details, private message text, addresses, or other sensitive information.
Scam intelligence
Track the patterns behind unwanted calls and texts
Roblock's recent-report pages show numbers added by date. The scam trends page explains common robocall, spoofing, telemarketing, and robotext patterns so people can understand the risk before they respond.
