Call centers operate in numerous countries worldwide, driven largely by globalization and outsourcing trends. In fact, global call center job creation rose by more than 32% in 2023, with marked growth in offshore regions such as the Philippines and India, according to a global call center location trends report. Emerging markets such as Latin America and Africa are experiencing growth as well.
With that, here are the top five call center countries worldwide, and why they made the cut.
What is an Accent?
Let’s begin here. Simply put, an accent is how a person pronounces a language. It can tell a lot about the speaker, including their geographical, ethnic, and socioeconomic background. Your accent can even reveal who you hang around.
You have an accent too, although you may not be aware of it. But if you’re from Alabama, for example, you’ll sound mighty different to someone in Massachusetts.
There are also dialects, which encompass a wider range of language features, including pronunciation, grammar, and vocabulary variations. In other words, an accent is only one part of a dialect.
The World’s Top Call Center Countries
The call center industry is growing and undergoing rapid change, transitioning over the last few decades from basic customer service centers to multifaceted, complex operations that provide a range of services such as inbound call support, customer relationship management, multichannel and technical support, lead calling, and sales.
However, all call centers are not created equally. Here are where the top call centers are located in early 2025, with factors including workforce education, technological infrastructure, English proficiency, labor costs, population density, and more.
The Philippines
Widely known as the call center capital of the world, the Philippines is the top location for call center outsourcing. Global companies are attracted to the centers’ operational efficiency and cost-effectiveness. Customers that outsource to the country can save up to 50% on operating costs.
The diverse country is used to working with global partners and has a high number of English speakers—nearly 70%. It also has an educated workforce, with a large portion of the country’s inhabitants possessing bachelor’s degrees.
India
Another leading country for call centers, India also boasts a large population of highly educated English speakers. With its low labor costs, the country has long been one of the top destinations for call centers, and even offers college programs for those who aim to become a call center agent.
The country’s workforce is known for its world class information technology, which spills over into an industry with growing technological advances. Thus, the call center labor force is more capable than most at solving technical problems and communicating effectively with customers.
Brazil
Brazil has a robust international call center presence in part due to the country’s proximity to the United States and Latin markets. The country is highly multilingual, with the top languages spoken being Portuguese, Spanish, English, and German, providing call centers with a competitive edge.
Additionally, Brazil is known for its IT and tech support services, and large organizations such as HP and IBM have outsourced their services to call centers there.
The Brazilian economy has seen steady growth, attracting global giants such as IBM. Brazil is also a cost-effective location, and its four time zones make it easy for companies in the Americas to communicate with each other, regardless of their location.
Poland
A rising hub, Poland has become a popular call center country for other English-speaking European markets. The country is known for its diverse culture and multilingualism, producing a talent pool that can easily cater to a myriad of European markets. Many of the country’s call centers are in Warsaw and Krakow.
Known for its high education standards, Poland also shines in the technology industry, particularly in programming and software. Further, the country has a business-friendly cost structure and has seen massive investments in infrastructure and training.
South Africa
South Africa is an emerging destination for call center outsourcing, with a large pool of bilingual, highly educated young people. It’s long been a destination for European countries seeking to outsource customer service needs. Politically stable, it has become a key market for countries including Australia, Canada, and the United States.
A regional leader economically, South Africa also has an increasingly well-developed infrastructure and continues to experience major investment. The benefits of South African call centers also include a skilled workforce and cost-effectiveness, with many centers located in Johannesburg, Cape Town, and Durban.
Accent Bias and Our Transformative Call Center Tool
Driven in part by the top call centers above, the global call center market was estimated at nearly $93 billion in 2023 and is expected to increase at a compound annual growth rate of 9.1% through 2030, according to Grand View Research.
With our accent-softening solution, we are contributing to this growth by helping to improve call center performance. It’s a fact: people are biased—often subconsciously—when it comes to how others speak. We tend to prefer our own accent over variations of our native language and assign to it more positive traits.
Take call center agents, for example, whose positions rely on their ability
to verbally communicate. English, for many of them, is their second or third language. The problem is that callers often react to agents’ accents with rudeness and frustration, sometimes questioning the representatives’ competence.
We have the solution.
Our accent neutralization solution is shaking up an industry that’s already swiftly changing, much of it due to artificial intelligence. Our AI-powered accent-reduction filter changes words—as they’re being spoken—into those that sound to the caller like a native speaker’s language. At length, the result is improved call center performance and growth.
