How to send a fax to Hong Kong

Why fax to Hong Kong?

Fax remains widely used in Hong Kong's legal, financial, and government sectors. Law firms, banks, insurance companies, and government departments routinely accept and send faxes for contracts, applications, and official correspondence. Many Hong Kong businesses still list a fax number alongside email on their letterheads and websites.

If a Hong Kong organisation asks you to fax a document, it is typically because their internal workflow requires a physical copy or a verifiable transmission record.

What you need

To send a fax to Hong Kong with unofax you need four things:

• Your document: PDF, Word, image, or any supported file. PDF gives the best results.
• The Hong Kong fax number: Hong Kong's country code is +852. Local numbers are 8 digits with no area code. A typical number looks like +852 2123 4567.
• 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 Hong Kong with unofax takes about two minutes:

• Upload your document: drag and drop or tap to select your file.
• Select Hong Kong and enter the fax number: choose Hong Kong from the country list. Type the 8-digit number (e.g. 2123 4567). unofax adds the +852 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 Hong Kong

A few things to keep in mind when faxing to Hong Kong:

• Business hours: Hong Kong operates on HKT (UTC+8) year-round with no daylight saving time. Standard business hours are 09:00 – 18:00 Monday to Friday. Faxes sent outside business hours will queue at the receiving machine.
• No area codes: Hong Kong does not use area codes. All local numbers are 8 digits. Landline fax numbers typically start with 2 or 3.
• Bilingual documents: Hong Kong is officially bilingual (Chinese and English). If faxing to a government department or large corporation, documents in either language are generally accepted. Including both can help with routing.
• Use PDF for best quality: many Hong Kong offices print and file incoming faxes. A clean, high-contrast PDF ensures your document is legible after printing.
• Include a cover sheet: Hong Kong businesses, especially legal and financial firms, expect a cover sheet identifying the sender, recipient, and page count.
