Which Viber Markets Are Worth Exploring? Greece, the Balkans and the Philippines

If you are considering putting a team behind Viber, Greece, Serbia, Bulgaria and the Philippines deserve an early discussion. This shortlist reflects established commercial activity and local context. It is not a ranking of measured Viber market shares in 2026.

The opportunity is a customer relationship that needs more than one message: clarifying a service, supplying information, arranging a time or resolving a post-purchase question. A familiar messaging channel may help a business carry that relationship forward. It is less likely to transform a product that gets one impression and no subsequent service.

Greece: think about service delivery, not only advertising

Viber’s January 2025 announcement about its small-business toolkit explicitly included self-service Business Accounts in Greece and the Philippines.[1] That establishes a local commercial-product footprint at the time. Check current official eligibility, features and fees before choosing a product.

For Greece, I would first examine businesses that require discussion before and after a transaction. Accommodation or itinerary services may need dates, party details and changes; suppliers serving local merchants may need to resolve specifications, stock and delivery. These are proposed applications, not verified customer success stories.

A modest starting point is whether customers want to continue a concrete arrangement on Viber after an initial inquiry elsewhere. A recognizable business and someone ready to answer may matter more than another promotion-heavy group. Advertising reach alone is not a service operation.

Serbia: an existing local relationship is a stronger starting point than global popularity

Viber has a long-running record of commercial activity in Serbia. Its recap of Digital 2022 describes local business and event uses.[2] Although the page carries a 2025 publication date, the event belongs to 2022. Historical audience figures from it should not be presented as this year’s penetration rate.

The practical implication is to ask existing distributors, partners or service customers whether Viber is a convenient business contact. The opportunity may involve supply, after-sales support, appointments or coordination rather than a mass consumer campaign.

Consider a hypothetical company developing relationships with local retailers. Knowing who handles purchasing, who can answer questions and which communication channel they prefer is more useful than buying a large list labelled Serbian Viber users. Viber may become an everyday entrance to a business relationship, but it does not create one that does not yet exist.

Bulgaria: connect an established presence to a problem you can solve

Viber’s retrospective on its 2023 market events gives Bulgaria particular attention and discusses brand-user messaging.[3] This supports researching the market. It does not make an old audience percentage a measure of your own customer coverage.

For businesses built around repeat purchases, appointments or after-sales service, a useful opening is an existing customer’s question: can they check replenishment, confirm an arrangement or get help with something they bought? Those conversations are closer to business value than the size of a potential broadcast list.

A local team or partner matters here. Product information can be translated; delivery commitments and useful support still require an operation that can fulfil them. Greece, Serbia and Bulgaria do not become interchangeable markets simply because they appear together on a regional map.

The Philippines: evaluate Viber inside the business you already have

The Philippines deserves more than a footnote after a European country list. On 22 October 2024, Rakuten announced Viber’s Manila office, describing local work in growth, B2B advertising and business messaging, and customer support.[4] Together with the small-business product footprint, that is a reason to assess the country independently rather than copy a European approach.

A more recent commercial signal arrived in April 2026: Infobip announced a deeper partnership with SM Supermalls, combining its SaaS solutions and Viber for Business across physical and digital customer touchpoints.[6] The retail application makes the opportunity more concrete: someone encounters a business in person, and the service relationship can continue on their phone. Teams with local retail partners, events or physical contact points have a reason to explore that connection rather than focus exclusively on online impressions.

For teams already receiving inquiries through websites, events or local partners, Viber can be a customer-selected follow-up option. A service provider can discuss a proposal, an order-led business can handle delivery questions, and a distributor can continue a partner conversation. In each case, the customer needs to want that channel. A Philippine phone number alone does not establish that preference.

Also distinguish what you need to buy or operate. Business discovery, advertising and enterprise messaging are different products. Viber’s Business Messages service has its own commercial context.[5] Its access and costs are not the same as ordinary account messaging or number screening.

Choose a market you can serve before counting the numbers you can check

If all four markets interest you, let existing business capability set the order. Local inquiries, partners and delivery capacity are usually a stronger place to start than an attractive penetration figure alone. In Greece, examine service arrangements; in Serbia, partner relationships; in Bulgaria, repeat purchase and support; in the Philippines, continuity between inquiry sources. These are starting angles, not a claim that each country fits only one kind of business.

If you hold a customer number list you are entitled to process, the AppShai Viber Number Checker can add list-level evidence through the supported registration or activity task. It describes your submitted records, not national market share, and registration is not buying intent. The comparison of Viber number screening and Business Messages explains that product distinction.

The opportunity may not be the next country with an explosive growth headline. For a business already serving these markets, it may be a simpler advantage: customers are willing to speak here, and you can turn that conversation into a useful service.
