Spam calls have become an ever-increasing nuisance across the globe, disrupting daily life and often posing risks such as scams and identity theft. One important way to understand and combat their spread is by identifying which country codes are most frequently used in these unwanted calls. Country codes represent the initial digits dialed to reach a specific country, and spammers often mask their true location by using various international codes.
Recognizing the top country codes involved in spam calls not only helps telecom providers, regulators, and consumers be more vigilant but also aids in developing more effective blocking technologies. This article explores the top 10 country codes most commonly utilized in spam calls worldwide, highlighting why these numbers are abused, the nature of the scam activities associated with them, and the challenges in tackling these cross-border spam operations that exploit international telephony systems.
+1 United States and Canada
The North American Numbering Plan (NANP) covers the United States, Canada, and several Caribbean nations, all accessible starting with the country code +1. The +1 code is the most frequently spoofed in spam calls, primarily because of the sheer volume of legitimate traffic that makes calls from this region appear trustworthy. Many spammers use this code to impersonate banks, government agencies, and well-known businesses to trick recipients into answering.
The extensive telecom infrastructure and widespread internet telephony have further facilitated the abuse of the +1 code. Additionally, the international perception of +1 as a domestic code often lowers the alertness of recipients, increasing the success rate of scams and fraudulent activities. Regulatory bodies and telecom companies face significant challenges blocking such spam calls without interfering with genuine communications originating from this heavily trafficked country code.
+44 United Kingdom
The United Kingdom, represented by the country code +44, is another hotspot frequently exploited for spam calls. The prevalence of +44 spam stems from the country’s robust global business environment and the popularity of mobile and VoIP services. Cybercriminals often spoof +44 numbers in phishing, tech support scams, and fraudulent lottery calls. Some of these calls originate from call centers operating overseas but deliberately use +44 to create legitimacy and reduce suspicion. Efforts within the UK to regulate malicious calls, including permitting customers to block nuisance calls and initiatives like the Telephone Preference Service, have had some impact, but spammers continue to evolve their techniques. The continuing popularity of +44 numbers for business and personal use further complicates detection, making this country code an enticing option for scammers trying to penetrate international target lists.
+91 India
India’s country code +91 has seen a rise in spam call activity, coinciding with the country’s rapid digital transformation and widespread mobile phone adoption. The vast population and growing telecom market provide an extensive pool from which scammers exploit both domestic and international targets. Many fraud calls originating with +91 numbers include offers of loans, fraudulent investment schemes, and fake job offers aimed at defrauding recipients. The proliferation of mobile numbers through cheaper devices and QR code-based SIM purchases has added to the challenges, as it becomes harder to track the source of each call. The Indian government and telecom regulators have introduced measures such as the TRAI’s anti-spam registry and the Distributed Ledger Technology-based Do Not Disturb platform to curb spam but face hurdles due to the sophisticated tactics of fraudsters and the sheer volume of calls generated daily.
+86 China
China’s country code +86 is heavily featured in spam call statistics, partly due to the country’s immense population and widespread usage of mobile telephony. Many spam operators exploit +86 numbers in scams that include fake lotteries, fraud attempts related to international remittances, and malware distribution via automated voice messages. The extensive manufacturing and telecom network in China have made it easier for scammers to deploy bulk robocalls and phone number spoofing techniques. Although the Chinese government has taken measures to regulate telecom providers and enforce strict penalties for illegal spam calls, the sheer scale of mobile usage and complexity of the telecommunications infrastructure create ongoing challenges. Additionally, international scammers sometimes disguise their phone numbers with +86 codes to confuse recipients and hide their real origins, leading to a persistent association of this country code with spam.
+234 Nigeria
Nigeria, identified by the country code +234, is infamously linked with scam calls, particularly those classified under “419 scams” or advance-fee frauds. The widespread use of +234 in spam calls is exacerbated by internet-based calling apps and SIM card sales that enable spammers to initiate fraudulent calls cheaply. Nigerian scammers often impersonate officials, banks, or foreign business representatives to coerce victims into sending money, disclosing personal information, or investing in fictitious ventures. The global reach of these scams leads to Nigerians’ country code frequently being flagged in international fraud alerts. Efforts by law enforcement agencies in Nigeria and other countries to crack down on these fraud operations have met with some success, but persistent economic incentives and evolving tactics mean that +234 remains a common country code used in spam and scam calls worldwide.
+7 Russia and Kazakhstan
The combined country code +7 for Russia and Kazakhstan is often linked with spam and scam calls internationally. Russia’s advanced cybercrime landscape and the presence of well-organized call centers contribute to the frequency of spam originating from these regions. Scammers using +7 numbers frequently run phishing campaigns, financial fraud schemes, and tech support fraud calls targeting Western countries. The ability to cloak the actual origin of calls behind the seemingly legitimate +7 code adds to the challenge of filtering and blocking these communications. Kazakhstan, sharing the same country code, sometimes sees spill-over effects from Russia’s telecom infrastructure, complicating enforcement and identification of bad actors. Governments and telecom providers in the affected regions have implemented policies to combat illegal spam calls, but criminals continuously update their methods to exploit the +7 code for fraudulent purposes globally.
+66 Thailand
Thailand, with the country code +66, has emerged as a notable location frequently used in spam call operations, largely due to its increasing internet penetration and growing telecom infrastructure. Many scammers target tourists, expatriates, and local residents using +66 numbers to deliver scams involving fake government benefits, travel offers, and financial fraud. The country’s affordable mobile SIM cards and VoIP technologies are exploited to hide criminal operations behind legitimate-looking numbers. Thailand’s telecom authorities are aware of the misuse of +66 in spam communications and have initiated steps to block illegal spam and enforce stringent telecommunications laws. Despite these measures, the prevalence of cheap technologies and the ability of cybercriminals to operate transnationally make +66 a recurring code in spam call reports worldwide, impacting not only local but also international consumers.
+20 Egypt
Egypt’s country code +20 frequently appears in spam call analyses, driven by similar telecom trends seen in other emerging markets. The widespread availability of mobile services combined with relatively low regulatory oversight in some regions facilitates the exploitation of +20 for scam activities. Egyptian scammers often engage in calls that involve fake lotteries, fraudulently promising job offers abroad, or impersonating financial institutions. The international diaspora of Egyptian communities also makes +20 calls an effective tool for scams that leverage familiarity and trust. Government interventions have targeted spoofing and fraudulent telecom practices to diminish spam calls, but challenges persist due to the ease with which criminals can obtain SIM cards and the growing sophistication of their tactics. The pattern of spam calls from +20 continues, contributing to the global burden of telecom fraud.
+852 Hong Kong
Hong Kong’s country code +852 is often leveraged in spam and scam calls, notably because of its status as an international financial hub. The high economic activity attracts scammers who exploit +852 numbers to pose as banks, investment advisors, or international lottery officials in phishing schemes. The city’s advanced telecommunication infrastructure paradoxically allows for a proliferation of robocalls and number spoofing. Although regulatory frameworks and telecom providers in Hong Kong have introduced measures to combat unsolicited calls, the dynamic and high-stakes environment makes it a popular choice for fraudsters. International fraud rings use +852 to gain legitimacy and target both local residents and global investors, resulting in calls designed to harvest financial or personal information. Continued vigilance and innovative controls are necessary to stem the volume of spam leveraging this prestigious country code.
+357 Cyprus
Cyprus, a smaller but strategically located country with the code +357, has recently seen its numbers misused by scammers for spam calls. The island’s role as a financial and corporate hub in the Mediterranean makes its country code attractive for fraudsters involved in investment scams, fake business opportunities, and technical support fraud. Many scams exploiting +357 involve impersonation of legitimate firms or government agencies to extract money or sensitive data from victims. Cyprus’s telecom regulators have been ramping up efforts to identify and stamp out spam and scam calls from this code, but the global connectivity and VoIP technologies allow the continued appearance of +357 numbers in unsolicited communications worldwide. The abuse of Cyprus’ country code highlights how even smaller markets are drawn into the complex web of international telecom spam operations.
