Call-forwarding codes by carrier
iOS may treat an in-app tap that dials a forwarding code as potential malware. Copy the code, open the Phone app yourself, paste it, and dial. Auto-dial from our app is optional and often blocked.
These are your carrier’s unconditional forward-all codes so inbound calls reach your Block The Calls number. Confirm against your carrier’s own support page if anything looks off. {number} is the 10-digit number we show in the app unless noted.
We are not a phone company. 911 and ordinary outbound calls stay on your native Phone app. After you dial, use Test forwarding in the app. we call your number from our network. The app does not dial our number to “test.”
