How to Call Hong Kong From the US [A 2024 Guide]

Each country has a unique calling code, which varies among nations. The country code or International Subscriber Dialing (ISD) code is used when making international calls. It is a telephone prefix used in International Direct Dialing (IDD).

Hong Kong’s country code is 852, and it is crucial to connect calls from other countries. If you wish to call from the US, the caller must dial the US exit code (011), Hong Kong’s ISD code, and Hong Kong’s phone number.
 

The distance between Hong Kong and the US is approximately 12,720 KM. These regions are too far from each other and have different time zones. The US, being a large country, has nine different time zones, while Hong Kong, a small region, follows only one time zone (UTC/GMT +8).

For example, if you place a call from US Pacific Standard Time (PST) California at noon on January 1, then it’d be 3 am in Hong Kong on January 2. So, it’s important to note time zones to avoid untimely calls. To simplify this, you can download a time zone app or browse current times in Hong Kong.

Here is a comparison.
 

Using your preferred device, you can call a landline or mobile phone directly in Hong Kong.

Follow the steps mentioned below.

Hong Kong is a small region with a country code (852). Every landline number in Hong Kong has eight digits; hence, calling these numbers is easy.

Follow these steps.

Step 1: Enter the US exit code (011)
Step 2: Enter the Hong Kong Code (852)
Step 3: Enter the eight-digit receiver’s telephone number (XXXX-XXXX)

For example, if the receiver’s landline number in Hong Kong is “12345678”, you need to dial “001-852-12345678”.

The steps for making calls to mobile phones are similar to those for landlines. The only difference is it needs mobile codes. As many mobile carrier service providers in Hong Kong, mobile codes start with 4,5, 6, 7, or 9, followed by the seven-digit phone number.

Step 1: Enter the exit code of the US (011)
Step 2: Dial the country code of Hong Kong (852)
Step 3: Press the mobile code
Step 4: Enter the recipient’s mobile phone number

For instance, if the receiver’s mobile number in Hong Kong is “2345678” with mobile code 5, you must dial “011-852-5-2345678”.

Dialing a Hong Kong toll-free number works exactly like calling any other phone number. The Hong Kong toll-free number starts with 800, and you can follow the steps below to make a call.

Step 1: Dial the US exit code (011)
Step 2: Enter the Hong Kong’s country code (852)
Step 3: Enter the toll-free number

For example: To dial the “800-123-456” toll-free number, use this format: “011-852-800-123-456”.

Note: A Hong Kong toll-free number may not be internationally accessible. Even if the call is successful, the caller must pay the international roaming charges.

Voice over Internet Protocol (VoIP) is a popular way to connect with you in Hong Kong from the US. These are internet-based platforms where people must use the same app to call someone. For example, one person on WhatsApp cannot place a call to Viber.

Here are some of the most popular apps that support VoIP calls.
 

• Facebook Messenger
• Skype
• WhatsApp
• FaceTime
• Viber
• Telegram

The benefit of using these platforms is that they are cost-effective. These platforms only require you and the person you’re calling to be on the same app and have a good Ethernet connection.

With an advantage, there’s a disadvantage, too, as you may not always have an Internet connection or a phone that doesn’t support the Internet.

Depending upon the carrier provider, the cost of dialing from the US to Hong Kong can vary. For instance, AT&T and T-Mobile in the US charge $15 monthly for unlimited international calling for 70+ countries.

While some other carriers can have international plans for a few minutes to hours, once you use all the minutes, you will be charged more. Because of this, international calls can cost you a lot. Thus, you must choose an alternative to make a call cost-effective.

Here are some tips for reducing call costs.
 

1. Leverage Wi-Fi calling: To use Wi-Fi calling, first enable it on your device. Then, go to settings and turn on this feature if available on your mobile. Now, you can use Wi-Fi to make calls over a traditional mobile network.
   
   Note: In most cases, it works on Android 6 and above.
    
2. Choose internet-based calling methods: Use apps like Facebook Messenger, WhatsApp, or other platforms to get the most cost-effective call. These methods use the internet to connect people.
    
3. Use international calling cards: You can use calling cards for both mobile and telephones. These credit card-sized cards can be purchased via local stores or online. An international calling card can cost you between $10 to $50.
