Is 936 a scam or spam risk?
936 is a legitimate geographic area code, not a premium or toll line, so a call from it costs you nothing extra. That said, scammers frequently spoof real local area codes to look familiar on caller ID. A genuine 936 number on your screen is no guarantee the caller is in Conroe, TX or trustworthy.
