Call center vs contact center explained: how the two differ in channels, staffing and technology, what each term means, and which one your business needs.
What is the difference between a call center and a contact center?
A call center handles customer conversations by telephone, inbound, outbound or both. A contact center handles the same conversations across several channels, such as phone, email, live chat, text, social media and self-service, through one platform so a customer's history follows them between channels. Every contact center includes a call center; not every call center is one.
The two terms are often used as if they meant the same thing, and in casual speech they nearly do. In a buying conversation the difference matters, because it changes what you are paying for: the channels covered, the skills agents need, the software that runs the operation and how performance is measured. This guide sets out each term, compares them side by side and explains how to tell which one your business actually needs. For the underlying definition of outsourced work in general, see what is BPO.
What is a call center?
A call center is a team of agents, with the systems that support them, whose job is to handle telephone calls for a business. Inbound call centers answer calls that customers place: orders, questions, complaints, appointments, technical problems. Outbound call centers place calls to customers or prospects: sales, follow-ups, surveys, collections, appointment reminders. Blended call centers do both, moving agents between queues as volume shifts during the day.
The defining feature is the single channel. Work arrives as a phone call, is handled as a phone call and is measured in telephone terms: calls offered, calls answered, average speed of answer, handle time, abandonment and first-call resolution. The agent's main tools are a telephone system, a script or knowledge base and the business's own customer records. A fuller treatment, including how inbound and outbound teams are organized, sits at what is a call center.
Call centers predate the internet, and the term carries that history. When a business says it wants to "outsource its call center," it may mean only its phone line, or it may be using the older word for a multi-channel operation. The first question a provider should ask is which channels the business actually receives contact on.
What is a contact center?
A contact center is an operation that handles customer conversations on every channel the business offers, from one platform, with one view of the customer. The telephone is still part of it, often the largest part, but email, live chat, text and messaging apps, social media comments and direct messages, web forms and video are handled by the same organization under the same rules and measurements.
The defining feature is the shared record. When a customer emails on Monday, chats on Tuesday and calls on Wednesday, the agent on Wednesday can see the first two conversations and does not ask the customer to repeat them. That is what distinguishes a true contact center from a business that simply has a phone team, an email team and a chat team sitting in different rooms with different tools. The industry term for the shared-record version is omnichannel, which is explained in the omnichannel customer service guide.
Contact centers are measured on the telephone metrics above plus channel-specific ones: email response time, chat concurrency, first response time on social, resolution rate per channel and, increasingly, how many contacts are resolved by self-service before an agent is involved. The outsourced version of the whole operation is described at contact center outsourcing.
How do call centers and contact centers compare?
The clearest way to compare the two is point by point, because the differences are in degree as much as in kind.
- Channels. A call center handles voice. A contact center handles voice plus email, chat, text, social media, messaging apps and self-service, through one routing engine.
- Customer record. A call center keeps a call history. A contact center keeps a single history across every channel, so context carries from one conversation to the next.
- Agent skills. Call center agents need a clear speaking voice, listening skills and the product knowledge to resolve a call. Contact center agents need those plus written communication, the ability to handle several chats at once and the judgment to move a conversation to a better channel.
- Technology. A call center runs on a telephone system with call routing, an IVR and a recording tool. A contact center adds a unified queue, digital channel connectors, a knowledge base shared across channels and reporting that treats every channel alike.
- Measurement. Call centers report telephone metrics. Contact centers report per-channel metrics and cross-channel outcomes such as resolution within a single conversation thread.
- Hours and routing. Both can run around the clock. A contact center can also shift demand between channels, for example by offering chat when the phone queue is long.
A related distinction, between a contact center and a help desk, turns on the kind of problem being solved rather than the channel. That comparison is at help desk vs call center.
How do staffing and training differ?
Staffing a call center means scheduling agents against a forecast of call volume by half-hour, with one agent handling one call at a time. Staffing a contact center means forecasting each channel separately and then deciding which agents handle which channels, because the channels behave differently. Email can wait hours; chat and phone cannot. A chat agent may handle two or three conversations at once; a phone agent handles one.
Training follows the same split. Every agent in either model learns the product, the systems and the rules. Contact center agents also learn to write in the brand's voice, to recognize when a chat should become a call, and to work from a shared knowledge base so the same question gets the same answer on every channel. Many contact centers organize agents into channel groups with a smaller cross-trained group that floats to wherever volume is highest.
Supervision differs as well. In a call center, a supervisor listens to recorded calls. In a contact center, a supervisor reviews transcripts, chat logs and social replies too, and quality scoring needs a rubric that works across written and spoken channels.
What technology runs each one?
A call center runs on a telephony platform that receives calls, plays an interactive voice response menu, queues the caller and routes the call to an available agent with the right skill. It records calls, reports on queues and connects to the business's customer records so the agent can see the account. Workforce management software forecasts volume and builds schedules.
A contact center runs on a platform that does all of that for voice and also connects email, chat, text, social and messaging channels into the same queue. Contacts are routed by skill regardless of channel, every interaction is logged against the same customer record, and reports treat a chat and a call as the same kind of work item. Most of these platforms are now delivered from the cloud, which is why the term cloud contact center has largely replaced older on-premises terminology. Cloud delivery also lets an outsourced team and the client's own staff work in one system from different locations.
Any platform that takes payments by phone or chat falls within the scope of PCI DSS, and any that handles health information for a covered entity in the United States falls under HIPAA. Businesses serving customers in the European Union or Canada also need the platform and the provider to meet GDPR or PIPEDA requirements for personal data. These rules apply equally to call centers and contact centers; the contact center simply has more channels to secure.
Which one does your business need?
A business needs a call center when its customers reach it almost entirely by telephone and it has no plan to add other channels. That is still common in trades, local services, appointment-based businesses and some older customer bases. A business needs a contact center when customers already reach it on more than one channel, or when it wants to add channels and keep one record of each customer.
A practical test is to look at where contacts actually arrive today. If email, web chat and social messages are already a meaningful share and are being handled by whoever happens to see them, the business is running an informal contact center without the tools or measurements. Formalizing that is usually the right next step. If the phone is the only channel and customers are satisfied with it, a well-run call center is the correct and simpler answer.
Outsourcing is possible for either. Call center outsourcing covers the voice-only version; contact center outsourcing covers the multi-channel version. Many businesses start with voice and add channels to the same provider as they grow, which is easier when the provider already runs a contact center platform.
How do you choose a provider for either model?
Choose a provider by asking about the channels it runs today, the platform it runs them on and how it reports across them. A provider that calls itself a contact center but reports only phone metrics is a call center with extra queues. A provider that can show one customer record across channels, one quality rubric and one forecast per channel is running a contact center. For broader outsourcing beyond customer contact, see BPO services.
If you are weighing the two models for your own business, request a proposal with the channels you receive contact on now, the ones you want to add and your hours of coverage, and we will outline how a team would be set up.
Call Center vs Contact Center: Frequently Asked Questions
Is a contact center the same as a call center?
No. A call center handles telephone calls only. A contact center handles calls plus email, chat, text, social media and other channels from one platform with one customer record. Every contact center contains a call center, but a call center on its own is not a contact center.
Why did the term contact center replace call center?
Because customers stopped reaching businesses only by phone. Once email, web chat and social media became normal ways to ask for help, the word call no longer described the work. Contact center covers every way a customer makes contact, which is why vendors and larger operations adopted it.
Can a small business have a contact center?
Yes. The term describes how channels are handled, not the size of the team. A small team that answers phone, email and chat from one cloud platform with a shared customer record is running a contact center. Many small businesses reach that point by outsourcing to a provider that already has the platform.
Do call center agents and contact center agents need different skills?
Partly. Both need product knowledge, listening skills and the ability to resolve a problem. Contact center agents also need strong written communication for email, chat and social replies, the ability to manage more than one chat at a time, and the judgment to move a conversation to a better channel.
Which compliance rules apply to call centers and contact centers?
The same rules apply to both. Card payments taken by phone or chat fall under PCI DSS. Health information handled for a United States covered entity falls under HIPAA. Personal data of EU or Canadian residents falls under GDPR or PIPEDA. Outbound calling and texting to consumers in the United States must follow the TCPA and Do Not Call rules.
