South Korea is one of the most digitally connected countries in the world, yet fax communication remains deeply embedded in Korean business culture. From legal firms and government agencies to real estate offices and healthcare providers, fax is still a required communication channel for official document transmission in Korea. Unlike many Western countries where fax usage has declined sharply, South Korea’s regulatory and legal framework continues to mandate fax for many business processes.
This is precisely why internet fax services (also called online fax, web fax, or mobile fax) have become essential tools for Korean professionals. Instead of maintaining bulky fax machines, businesses now send and receive faxes directly from their smartphones, tablets, and computers — anytime, anywhere.
This guide compares the top internet fax services available in South Korea, covering pricing, features, reliability, and mobile app quality to help you make the best choice for your business.
The Korean internet fax market is distinct from the global market in several important ways. First, Korean fax services provide local Korean phone numbers (Seoul 02, regional area codes, and 070 internet phone numbers), which is critical for businesses that need a recognizable, professional fax number. Second, Korean services are optimized for the Korean telecom infrastructure, ensuring high delivery success rates to domestic fax machines. Third, compliance with Korean data protection laws (such as the Personal Information Protection Act, PIPA) is built into domestic services.
While international services like eFax, Fax.Plus, and RingCentral Fax are well-known globally, they have significant limitations for Korean users: they typically cannot provide Korean local numbers, may have slower delivery to Korean fax machines due to international routing, and their customer support is not available in Korean. For these reasons, Korean-based internet fax services dominate the domestic market.

LG U+ WebFax is offered by LG Uplus, one of South Korea’s three major telecommunications carriers. As a telecom-backed service, it benefits from LG U+’s extensive network infrastructure. It supports both PC and mobile fax transmission and may offer bundled discounts for existing LG U+ subscribers.
However, as a subsidiary product within a large telecom portfolio, its fax-specific features and app experience may not be as specialized or frequently updated as dedicated fax service providers like HanaFax.
SK Broadband, part of the SK Telecom group, one of South Korea’s three major telecommunications carriers. As a telecom-backed service, it benefits from SK Broadband’s extensive network infrastructure, this is a telecom-carrier-based service that may appeal to existing SK subscribers seeking bundled services. Feature depth and mobile app quality vary compared to specialized providers.
EnFax is a Korean internet fax sending service that has been operating for many years. It focuses primarily on outbound fax transmission rather than providing a full send-and-receive fax number solution. EnFax can be useful for businesses that mainly need to send faxes rather than receive them.

If your business operates in South Korea or frequently communicates with Korean counterparts, choosing a domestic internet fax service offers decisive advantages over international alternatives.
Korean Local Number Availability
Korean internet fax services provide genuine Korean phone numbers with recognizable area codes (02 for Seoul, 031 for Gyeonggi, etc.). International services like eFax or Fax.Plus typically cannot provide Korean local numbers, which means your business fax number would appear as a foreign number — a significant credibility issue in Korean business culture.
Delivery Reliability to Korean Fax Machines
Domestic services route faxes through Korean telecom networks, resulting in faster transmission and higher delivery success rates to Korean fax machines. International services must route through overseas gateways, which can introduce delays and occasional delivery failures.
Korean-Language Support and Interface
Full Korean-language apps, web interfaces, and customer support (phone, chat, and email in Korean) ensure that all team members can use the service without language barriers. Global services typically offer only English-language support.
Compliance with Korean Regulations
Korean fax services comply with the Personal Information Protection Act (PIPA) and other Korean data regulations. Data is stored on servers within South Korea, which is increasingly important for businesses in regulated industries such as finance, healthcare, and legal services.
Cost Advantage
At KRW 5,000/month (approximately USD $3.50), Korean services like HanaFax and MyFax are significantly more affordable than international competitors. eFax’s basic plan starts at $16.95/month, and even Fax.Plus charges $6.99/month for its entry-level paid plan. For Korean businesses, the domestic option provides better features at a fraction of the cost.
When selecting an internet fax service for your Korean business, consider these key factors:
1. Do you need to receive faxes? If yes, choose a service that provides a dedicated Korean fax number (HanaFax, MyFax, SK Broadband). If you only send, EnFax or pay-per-use options may suffice.
2. How important is mobile access? If you frequently need to fax documents while away from your desk, prioritize services with top-rated mobile apps. HanaFax’s app is consistently rated highest in Korean app stores.
3. Volume and frequency? High-volume users should look for flat-rate or discounted per-page pricing. For occasional use, pay-per-use models may be more economical.
4. Enterprise needs? If your organization requires API integration, multi-user management, or compliance documentation, contact HanaFax for enterprise solutions.
5. International fax needs? If you also need to send faxes to international numbers, verify that the service supports international transmission. HanaFax supports international fax sending.

Can I use eFax or Fax.Plus in Korea?
While you can technically use international services like eFax or Fax.Plus from Korea, they have significant limitations for Korean users. They cannot provide Korean local fax numbers, customer support is in English only, fax delivery to Korean numbers may be slower or less reliable due to international routing, and pricing is substantially higher. For businesses operating in Korea, domestic services are strongly recommended.
How much does internet fax cost in Korea?
Korean internet fax services are very affordable. HanaFax and MyFax both charge KRW 5,000/month (approximately USD $3.50) for a dedicated fax number with incoming fax service. Outbound faxes cost KRW 42 per page on HanaFax. This is significantly cheaper than international alternatives like eFax ($16.95/month) or Fax.Plus ($6.99/month).
Do Korean internet fax services work internationally?
Yes. Major Korean internet fax services like HanaFax support both domestic and international fax sending. You can send faxes to international numbers from your Korean fax account.
Is fax still commonly used in South Korea?
Yes. Despite South Korea’s advanced digital infrastructure, fax remains a standard business communication tool, especially in legal, government, real estate, healthcare, and logistics sectors. Many official processes in Korea still require fax transmission of signed documents. This is why the online fax market in Korea continues to remain strong and relevant.
Can I get a Seoul fax number with an internet fax service?
Yes. Korean internet fax providers like HanaFax offer Seoul (02) area code numbers, as well as numbers from all other Korean regional area codes and 070 internet phone numbers. This allows your business to have a professional local fax presence regardless of your physical location.
For businesses operating in South Korea, choosing the right internet fax service can make a meaningful difference in daily operational efficiency. While global services like eFax and Fax.Plus serve international markets well, the Korean market is best served by domestic providers that understand local business needs, provide Korean phone numbers, offer Korean-language support, and comply with Korean data regulations.
