About

Missed a call from a number you don't know? SpamCheck calls it for you and records what happens from the first ring, so you can find out who it is without calling back. HOW IT WORKS Enter or paste a number, or share it from Messages, Mail or Safari. We call it from one of our numbers and record 45 seconds from the first ring. You hear exactly what any caller would: the ringing, a voicemail greeting, a business answering, a carrier message or a person picking up. Results usually arrive in about a minute. THEY NEVER SEE YOUR NUMBER The call comes from one of our numbers, a different one each time. Your number is never shown to the person you check. FLAG SPAM AND BLOCK IT After a check, mark a number as spam with a category like scam, robocall, telemarketing or debt collector. Turn on call blocking and your iPhone labels calls from flagged numbers and silences calls from numbers you block. PRIVATE BY DESIGN No sign up, no email and no name. No ads, analytics or tracking. Your results, labels, spam flags and blocked numbers stay on your iPhone, and we delete our copy of each result as soon as your phone has it. SIMPLE CREDITS Each check costs one credit. Buy credits as you need them with no subscription. Checks that fail because of us are refunded automatically. Works with numbers in the United States and Canada.
