How to send a fax to South Korea

Why fax to South Korea?

Despite being one of the most digitally advanced countries in the world, South Korea still uses fax extensively in government, legal, banking, and healthcare settings. Courts, tax offices, hospitals, and insurance companies routinely require faxed documents for applications, claims, and official filings. Many Korean businesses — particularly in manufacturing and logistics — use fax alongside digital systems for order confirmations and contracts.

If a Korean organization asks you to fax a document, it is typically because their compliance or administrative processes require a faxed copy.

What you need

To send a fax to South Korea with unofax you need four things:

• Your document: PDF, Word, image, or any supported file. PDF gives the best results.
• The Korean fax number — South Korea's country code is +82. Drop the leading zero from the area code when dialing internationally. A typical number looks like +82 2 1234 5678 (Seoul) or +82 51 123 4567 (Busan).
• A payment method: credit card, debit card, Apple Pay, or Google Pay.
• Your email address: for delivery confirmation and proof of receipt.

No account, no subscription, no fax machine required.

Step by step

Sending a fax to South Korea with unofax takes about two minutes:

• Upload your document: drag and drop or tap to select your file.
• Select South Korea and enter the fax number: choose South Korea from the country list. Type the number without the leading zero. unofax adds the +82 country code automatically.
• Enter your email: provide your email address for delivery confirmation and proof of receipt.
• Preview: check each page in the preview. Add a free cover sheet if the recipient requires one.
• Pay: the per-page price is shown upfront. Pay with card, Apple Pay, or Google Pay.
• Done: your fax is sent immediately. You receive a delivery confirmation once the receiving machine acknowledges receipt.

Tips for faxing to South Korea

A few things to keep in mind when faxing to South Korea:

• Business hours: South Korea uses Korea Standard Time (UTC+9).
• Drop the leading zero: local area codes such as 02 or 051 lose the first 0 after +82.
• Department routing matters: include company, department, recipient name, and reference numbers when available.
• Use PDF for best quality: official forms, scans, and signed documents fax more clearly when converted to a clean PDF before upload.
• Korean text is fine: upload a PDF for best results when sending Korean-language documents.

Common South Korea fax situations

• Government and court paperwork: offices may ask for faxed applications, filings, certificates, or signed forms.
