Hong Kong is one of the easiest countries in the world to fax, and one of the few where nothing has to be removed from the number. There are no area codes, no trunk prefix and no leading zero to worry about. Every Hong Kong number is exactly eight digits, and you dial all eight.

It is also a place where fax genuinely persists. As an international finance and trade hub, Hong Kong keeps fax alive across banking, shipping and logistics, law firms, and government departments, where a transmission record with a timestamp still carries weight.

The Cheapest Way to Fax to Hong Kong

OverseasFax charges a flat $2.99 per fax for up to 3 pages to Hong Kong, with no account, no subscription and no monthly fee. Extra pages are $0.99 each. If the fax fails to deliver you are refunded automatically.

Compare that with a monthly service like eFax at roughly $16.95 to $18.99 a month whether you fax or not, or an in store international fax at FedEx Office at around $5.99 for the first page and $3.99 for each page after.

Hong Kong Fax Number Format, Country Code +852

Country code: +852

Format: +852 followed by all 8 digits, exactly as written

Landline example: 2174 0019 → enter as 21740019

Landline example: 3456 7890 → enter as 34567890

Landlines start with: 2 or 3

Mobiles start with: 5, 6, 7 or 9

Important: OverseasFax adds +852 automatically. Never type it yourself.

The good news about Hong Kong: there is nothing to remove. Hong Kong has no area codes and no trunk prefix, so unlike Germany, the UK or Japan there is no leading zero to drop, and unlike Italy there is no zero to keep. You enter the 8 digits exactly as they appear.

The +852, +853 and +86 Trap

This is the mistake that actually costs people money. Hong Kong is +852. Macau is +853, one digit away. Mainland China is +86. These are three completely separate telephone networks. A Hong Kong number cannot be reached on +86, and a mainland number cannot be reached on +852.

Because Hong Kong is a Special Administrative Region of China, people reasonably assume it shares China's country code. It does not, and it never has. If you select China on the dropdown for a Hong Kong number, the fax will not arrive and you will also have paid the Tier 3 price of $4.99 instead of Hong Kong's $2.99.

Select Hong Kong for any number starting 2, 3, 5, 6, 7 or 9 with eight digits. Select China only for mainland numbers.

Hong Kong Has No City Codes

This surprises people used to Germany or Japan. Hong Kong abolished area codes at the end of 1989. Central, Kowloon, Tsim Sha Tsui, Wan Chai, Sha Tin and the New Territories all use the same flat 8 digit numbering plan. There is no Hong Kong Island code and no Kowloon code to look up.

What you might expectReality in Hong Kong
An area code for KowloonNone. All numbers are 8 digits.

Step by Step, How to Send a Fax to Hong Kong

1
Upload your document

Go to OverseasFax.com and upload your PDF, Word document or image. You can add up to 10 files in one fax.

2
Select Hong Kong (+852)

Choose Hong Kong from the country dropdown, not China. The +852 code is added automatically and the $2.99 price appears instantly.

3
Enter all 8 digits

Type the number exactly as written, for example 21740019. Nothing to add, nothing to remove.

4
Pay and send

Enter your email for delivery confirmation and pay securely via Stripe. Your fax is sent immediately and usually delivered within 5 to 15 minutes.

Why Hong Kong Still Uses Fax

Hong Kong is an international finance, trade and shipping hub, and those are precisely the industries where a documented, timestamped transmission still matters. Banks accept signed instructions by fax. Shipping and logistics companies exchange bills of lading, customs paperwork and delivery orders by fax. Law firms use it for formal correspondence. Government departments publish fax numbers for submissions.

Hong Kong business culture also runs late, with many offices open until 7pm or later, which matters if you are sending from the US and worrying about the machine being switched on.

Who Needs to Fax Hong Kong?

Tips for a Successful Fax to Hong Kong

Select Hong Kong, not China. This is the number one cause of failure and it also overcharges you by $2.00.

Count the digits. Every Hong Kong number is exactly 8 digits. More or fewer means the number is wrong.

Mind the 13 hour gap. Hong Kong is UTC+8 with no daylight saving, which is 13 hours ahead of US Eastern. Sending at 8pm to 10pm US Eastern lands in Hong Kong's 9am to 11am.

Use PDF so Chinese characters stay sharp, since fax transmits in black and white at low resolution.

Frequently Asked Questions, Faxing to Hong Kong

What is the cheapest way to fax to Hong Kong?
OverseasFax at $2.99 for up to 3 pages, with no account and no subscription. Extra pages are $0.99 each. Monthly services like eFax charge roughly $16.95 to $18.99 whether you fax or not, and FedEx Office charges about $5.99 for the first international page.
What is the cheapest way to fax to Hong Kong from the US?
From the US, OverseasFax is the cheapest at $2.99 for up to 3 pages with no subscription. The +852 code is added automatically and you send from any browser, so there is no fax machine and no Hong Kong phone line involved.
Can I fax to Hong Kong for free?
Free international fax services are rare, usually cap you at a page or two, add branding to your cover sheet and often fail on overseas routes. For a reliable fax to Hong Kong, OverseasFax is a low flat $2.99 with an automatic refund if it fails.
Is there a cheap way to fax Hong Kong without a subscription?
Yes. OverseasFax lets you fax Hong Kong for $2.99 per fax with no subscription, no account and no monthly fee. You pay only when you actually send.
What is the country code for Hong Kong?
+852. On OverseasFax you select Hong Kong from the dropdown and +852 is added automatically, so you never type it. Note that Hong Kong does not use China's +86.
Is Hong Kong's country code the same as China's?
No, and this is the single most common mistake. Hong Kong is +852, mainland China is +86, and Macau is +853. They are three completely separate telephone networks. A Hong Kong number cannot be reached using +86.
What is the difference between +852 and +853?
+852 is Hong Kong and +853 is Macau. They are one digit apart and are entirely separate networks. If you are faxing Macau, do not select Hong Kong, and vice versa.
Do I drop the leading zero when faxing Hong Kong?
No, because there is no leading zero to drop. Hong Kong has no trunk prefix and no area codes. Enter all 8 digits exactly as written. This makes Hong Kong one of the simplest countries to fax.
Does Hong Kong have area codes?
No. Hong Kong abolished area codes at the end of 1989. Central, Kowloon, Tsim Sha Tsui, Wan Chai, Sha Tin and the New Territories all use the same flat 8 digit numbering plan.
How many digits is a Hong Kong fax number?
Exactly 8, always. If you have more or fewer than 8 digits after +852, the number is wrong. Landlines start with 2 or 3, mobiles with 5, 6, 7 or 9.
What does a Hong Kong fax number look like?
Eight digits starting with 2 or 3 for a landline, for example 2174 0019, which you enter as 21740019. In international format it appears as +852 2174 0019.
How do I know if a Hong Kong number is a landline or a mobile?
By the first digit. Landlines start with 2 or 3. Mobiles start with 5, 6, 7 or 9. Numbers starting with 8 can be personal numbering or special services. Fax machines are almost always on landlines.
Can I fax to a Hong Kong mobile number?
Technically the number is reachable, but a mobile is very unlikely to be a fax machine. Fax numbers in Hong Kong are nearly always landlines starting with 2 or 3. Check you have the fax number rather than the phone number.
Why did my fax to Hong Kong fail?
The most common cause is selecting China instead of Hong Kong, which routes to +86 and cannot reach a Hong Kong number. Other causes are a busy line, a machine that is switched off, or a wrong digit count. OverseasFax refunds automatically and emails you the reason.
What is the fax number format for Hong Kong?
+852 followed by all 8 digits with nothing removed. There is no area code and no trunk prefix. OverseasFax adds the +852 for you, so you simply enter the 8 digits.
Can I fax a Hong Kong bank?
Yes. Hong Kong banks and brokerages accept signed instructions and account forms by fax. Confirm the fax number from the bank's official site and use PDF so signatures stay crisp.
Can I fax a Hong Kong shipping or logistics company?
Yes, and it is one of the most common uses. Freight forwarders and shipping agents in Hong Kong exchange bills of lading, customs paperwork and delivery orders by fax daily.
Can I fax a Hong Kong law firm?
Yes. Hong Kong solicitors and notaries keep active fax lines for formal correspondence, where a timestamped transmission record matters.
Can I fax a Hong Kong government department?
Yes. Hong Kong government departments publish fax numbers for submissions. Always use the number from the department's official website rather than a directory.
Can I fax a Hong Kong hotel?
Yes. Hong Kong hotels accept credit card authorization forms and booking documents by fax. Confirm the number with the hotel and send during Hong Kong business hours.
Can I fax a Hong Kong company or supplier?
Yes. Trading companies and suppliers in Hong Kong use fax for purchase orders, invoices and proforma documents. Include a cover sheet with the recipient's name and department.
Can I fax to Hong Kong from my iPhone?
Yes. Open overseasfax.com in Safari, upload your document, select Hong Kong, enter the 8 digit number and pay $2.99. No app needed.
Can I fax to Hong Kong from a Mac?
Yes. Open overseasfax.com in any browser on your Mac, upload, select Hong Kong, enter the number and pay. Nothing to install.
How long does a fax to Hong Kong take?
Most faxes to Hong Kong are delivered within 5 to 15 minutes. You receive an email confirmation with a delivery reference ID once it is transmitted.
What is the best time to fax Hong Kong from the USA?
Hong Kong is UTC+8 with no daylight saving, which is 13 hours ahead of US Eastern. Sending between 8pm and 10pm US Eastern arrives during Hong Kong's 9am to 11am. Hong Kong offices often run until 7pm or later, which widens the window.
Does Hong Kong observe daylight saving time?
No. Hong Kong stays on UTC+8 all year, so the time difference from the US shifts only when the US changes its own clocks, not Hong Kong's.
Do I need an account to fax Hong Kong?
No. OverseasFax needs no account, no registration and no login. Upload, select Hong Kong, enter the number, pay $2.99 and send.
What file types can I fax to Hong Kong?
PDF, Word (.doc and .docx), and images (JPG, PNG, GIF, BMP). PDF gives the clearest result, which matters if your document contains Chinese characters.
Can I fax documents in Chinese to Hong Kong?
Yes. OverseasFax transmits documents in any language, including Traditional Chinese. Use PDF so the characters stay sharp, since fax is black and white at low resolution.
Should I write to Hong Kong in Traditional or Simplified Chinese?
Hong Kong uses Traditional Chinese, along with English as an official language. Mainland China uses Simplified. For business, English is widely accepted in Hong Kong.
Is it safe to fax sensitive documents to Hong Kong?
Yes. Documents are transmitted over an encrypted connection and deleted from the servers after sending. Fax is a point to point transmission, which is part of why Hong Kong banking and legal work still uses it.
What happens if my fax to Hong Kong fails?
You get a full automatic refund and an email explaining the reason, such as a busy line or a machine that was off. You can try again whenever you are ready.
Can I get a refund if my fax to Hong Kong doesn't deliver?
Yes. Every fax that fails to deliver is refunded automatically to your original payment method. You do not need to request it.
How many pages can I fax to Hong Kong?
The $2.99 price covers up to 3 pages, with extra pages at $0.99 each. You can send up to 10 files in a single fax, up to 100MB total.
Can I fax multiple documents to Hong Kong at once?
Yes. Upload up to 10 files and OverseasFax combines them into one fax in the order you add them. Pricing is based on the total page count.
How much does it cost to fax 10 pages to Hong Kong?
$2.99 covers the first 3 pages and each additional page is $0.99, so 10 pages costs $2.99 plus 7 extra pages at $0.99, which is $9.92. The price is shown before you pay.
Is faxing to Hong Kong cheaper than eFax?
For occasional faxes, considerably. OverseasFax is $2.99 per fax with no subscription. eFax charges around $16.95 to $18.99 every month whether you send a fax or not, plus a setup fee.
Can I fax to Macau instead of Hong Kong?
Macau is a separate country code, +853, and a separate selection. Do not select Hong Kong for a Macau number. Check the OverseasFax dropdown for Macau availability and pricing.
Can I fax from Hong Kong to the US?
Yes. You can send from anywhere with a browser. For a US or Canada destination, our sister service FaxForADollar.com is cheaper at $1.00 for up to 10 pages.
Is fax still used in Hong Kong in 2026?
Yes, particularly in banking, shipping and logistics, law and government, where a timestamped transmission record still carries weight. Hong Kong's role as a trade and finance hub keeps fax in daily use across those sectors.
Do Hong Kong businesses prefer fax or email?
Both are used, but fax persists for anything needing a signed original with a verifiable transmission record, especially in banking, shipping documentation and legal correspondence.
Can I fax to the New Territories or Kowloon?
Yes, the same way as anywhere in Hong Kong. There are no regional codes, so a number in Kowloon, Central, Sha Tin or the New Territories is the same 8 digit format.
