You might feel tempted to call back, wondering if it is important. That single moment of curiosity is exactly what scammers are counting on.<\/span><\/p>\n<p><span data-contrast=\"none\">Known as the\u202f<\/span><b><span data-contrast=\"none\">One Ring Scam<\/span><\/b><span data-contrast=\"none\">\u202for &#8220;Wangiri&#8221; (Japanese for &#8220;one ring and cut&#8221;), this scam has been around for years and continues to trap thousands of people worldwide.

The simplicity of the tactic makes it difficult for phone carriers and regulators to shut it down completely.<\/span><\/p>\n<p><span data-contrast=\"none\">Here is what you need to know to protect yourself and your loved ones.<\/span><\/p>\n<h3><b><span data-contrast=\"none\">Premium-Rate and International Fee Scams<\/span><\/b><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/h3>\n<p><span data-contrast=\"none\">This is the most common version of the One Ring Scam. It works like this:<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<ul>\n<li><b><span data-contrast=\"none\">The Call:<\/span><\/b><span data-contrast=\"none\">\u202fScammers use automated dialers to make thousands of quick calls, each ringing just once before disconnecting.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><b><span data-contrast=\"none\">The Trap:<\/span><\/b><span data-contrast=\"none\">\u202fIf you call back, you are unknowingly connected to a <\/span><b><span data-contrast=\"none\">premium-rate international number<\/span><\/b><span data-contrast=\"none\">.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><b><span data-contrast=\"none\">The Cost:<\/span><\/b><span data-contrast=\"none\">\u202fYou immediately start incurring hefty per-minute charges and connection fees. Scammers profit because they get a share of the call revenue.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<\/ul>\n<p><span data-contrast=\"none\">Many of these calls come from Caribbean or West African area codes that can look like U.S. numbers. Known high-risk area codes include\u202f<\/span><b><span data-contrast=\"none\">268 (Antigua)<\/span><\/b><span data-contrast=\"none\">,\u202f<\/span><b><span data-contrast=\"none\">284 (British Virgin Islands)<\/span><\/b><span data-contrast=\"none\">,\u202f<\/span><b><span data-contrast=\"none\">809 (Dominican Republic)<\/span><\/b><span data-contrast=\"none\">,\u202f<\/span><b><span data-contrast=\"none\">232 (Sierra Leone)<\/span><\/b><span data-contrast=\"none\">, and\u202f<\/span><b><span data-contrast=\"none\">222 (Mauritania)<\/span><\/b><span data-contrast=\"none\">.<\/span><\/p>\n<p><span data-contrast=\"none\">This scam thrives on human nature. Our curiosity or the feeling that we might miss an important call often leads us to return the call. With caller ID spoofing, scammers can make these numbers look local, making it even harder to spot.<\/span><\/p>\n<h3><b><span data-contrast=\"none\">Plea for Information and Money Scams<\/span><\/b><\/h3>\n<p><span data-contrast=\"none\">While many One Ring scams stop at premium-rate charges, some evolve into more manipulative schemes:<\/span><\/p>\n<p><b><span data-contrast=\"none\">Plea for Information Scams<\/span><\/b><\/p>\n<p><span data-contrast=\"none\">After you return the call, the scammer might strike up a conversation pretending to need help. They may sound friendly or urgent, asking you to &#8220;verify&#8221; personal information such as your full name, date of birth, or even banking details. These pieces of information can be sold or used for identity theft.<\/span><\/p>\n<p><b><span data-contrast=\"none\">Plea for Money Scams<\/span><\/b><\/p>\n<p><span data-contrast=\"none\">In more aggressive attempts, scammers impersonate authority figures like lawyers, bank representatives, or even relatives in trouble. They create urgency by claiming you need to wire money or send a payment immediately to help someone or to avoid a legal issue. Victims have reported losing thousands of dollars this way.<\/span><\/p>\n<h3><b><span data-contrast=\"none\">Warning Signs You Are Being Targeted<\/span><\/b><\/h3>\n<ul>\n<li><span data-contrast=\"none\">Missed calls from unfamiliar or suspicious-looking area codes<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li data-leveltext=\"\uf0b7\" data-font=\"Symbol\" data-listid=\"2\" data-list-defn-props=\"{&quot;335552541&quot;:1,&quot;335559685&quot;:720,&quot;335559991&quot;:360,&quot;469769226&quot;:&quot;Symbol&quot;,&quot;469769242&quot;:[8226],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;\uf0b7&quot;,&quot;469777815&quot;:&quot;multilevel&quot;}\" data-aria-posinset=\"1\" data-aria-level=\"1\"><span data-contrast=\"none\">Calls that ring once or hang up immediately<\/span><\/li>\n<li data-leveltext=\"\uf0b7\" data-font=\"Symbol\" data-listid=\"2\" data-list-defn-props=\"{&quot;335552541&quot;:1,&quot;335559685&quot;:720,&quot;335559991&quot;:360,&quot;469769226&quot;:&quot;Symbol&quot;,&quot;469769242&quot;:[8226],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;\uf0b7&quot;,&quot;469777815&quot;:&quot;multilevel&quot;}\" data-aria-posinset=\"1\" data-aria-level=\"1\"><span data-contrast=\"none\">Multiple one-ring calls in a short period<\/span><\/li>\n<li data-leveltext=\"\uf0b7\" data-font=\"Symbol\" data-listid=\"2\" data-list-defn-props=\"{&quot;335552541&quot;:1,&quot;335559685&quot;:720,&quot;335559991&quot;:360,&quot;469769226&quot;:&quot;Symbol&quot;,&quot;469769242&quot;:[8226],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;\uf0b7&quot;,&quot;469777815&quot;:&quot;multilevel&quot;}\" data-aria-posinset=\"1\" data-aria-level=\"1\"><span data-contrast=\"none\">No voicemail or clear message left<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<\/ul>\n<p><b><span data-contrast=\"none\">How to Protect Yourself<\/span><\/b><\/p>\n<ul>\n<li><span data-contrast=\"none\">Do not call back numbers you do not recognize, especially if they only rang once.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><span data-contrast=\"none\">Check area codes online before dialing unfamiliar numbers.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><span data-contrast=\"none\">Learn <\/span><a href=\"https:\/\/www.usa.gov\/imposter-scams\"><span data-contrast=\"none\">how to spot different types of imposter scams<\/span><\/a><span data-contrast=\"none\">.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><span data-contrast=\"none\">Ask your phone provider about blocking outgoing international or premium-rate calls.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><span data-contrast=\"none\">Use scam-blocking services or apps that automatically filter suspected fraud calls.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><span data-contrast=\"none\">Review your phone bill regularly for unknown charges<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><span data-contrast=\"none\">Report the incident to your bank and local police, especially if you&#8217;ve suffered a loss.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:0,&quot;335559740&quot;:240}\">\u00a0<\/span><\/li>\n<li><span data-contrast=\"none\">Report suspicious calls to the\u202f<\/span><a href=\"https:\/\/consumercomplaints.fcc.gov\/hc\/en-us\"><span data-contrast=\"none\">FCC<\/span><\/a><span data-contrast=\"none\"> or the\u202f<\/span><a href=\"https:\/\/www.donotcall.gov\/\"><span data-contrast=\"none\">FTC<\/span><\/a><span data-contrast=\"none\">.<\/span><\/li>\n<\/ul>\n<p><b><span data-contrast=\"none\">Stay Alert, Stay Safe<\/span><\/b><\/p>\n<p><span data-contrast=\"none\">The One Ring scam thrives on curiosity and quick reactions.
