Hong Kong Postal Code

If you’ve tried to fill out an online form, input an address into a human resources database, or run payroll for an employee in Hong Kong, you probably asked yourself the following question: “What is the Hong Kong postal code?”

Most countries use postal or ZIP codes in sorting and delivering mail but Hong Kong does not. It does not use postal codes, and this is generally where the issue starts for business executives, HR personnel, and expatriates.

In this article, we will outline all you need to know about Hong Kong postal codes. We will also cover how to manage instances where one is needed. This small detail will be relevant to your business activities and compliance, especially in HR and payroll tasks.

    Does Hong Kong have a postal code?

    No, Hong Kong does not have, nor does it use, postal codes.

    Hongkong Post states that you do not need to use a postal or ZIP code when sending mail to a Hong Kong address, whether local or international. The city’s mail system relies on detailed addresses that feature building names, floors, flat numbers, and districts.

    Bottom line: Hong Kong mail will still arrive without a postal code, as long as the address is formatted correctly.

    Why are some systems still requesting a postal code?

    While Hong Kong does not need postal codes, some online applications use worldwide templates that ask for a ZIP or postal code in order to fill out a form.

    They include:

    • Web HR and payroll solutions (like Deel, ADP)
    • Bank account applications
    • Government registration forms
    • e-commerce shipping platforms
    • Tax filing portals
    • Employee onboarding documents

    If you’re using payroll or recruiting in other countries, you’ve probably seen the required “postal code” field. If not filled in, it can cause delays or system problems.

    What postal code would you use for Hong Kong?

    If you need to fill in a postal code for a Hong Kong address, here are the standard placeholders:

    • 00000 – Generic numeric placeholder
    • The ISO and IATA code of Hong Kong is HKG.
    • NA or Not Applicable – If text is fine
    • 999077 is also supported on certain platforms (though not officially)

    Do not use international postal codes such as Chinese or US ones. This will lead to address issues, failed checks, or rule problems.

    How to Write a Hong Kong Address Correctly

    Hong Kong possesses a clear address system, despite lacking postal code. This is the way to properly record addresses in HR systems, employees’ contracts, or payroll systems.

    Example Address:

    Formatting Tips:

    • Always mention the flat number, floor, building name, and street name.
    • Fill in with the appropriate region: Hong Kong Island, Kowloon, or New Territories
    • Include a postal code only if the system explicitly asks for it.

    This formatting guarantees successful document delivery, address verification, and legal adherence in agreements.

    Why It Matters to HR and Payroll

    HR and finance departments often need to send correct addresses for:

    • Employee records
    • Tax returns and MPF contributions
    • Employment contracts
    • Work visa or dependent visa applications
    • Payroll setup and payments

    Inaccurate or incomplete addresses — even without a solution for a postal code — can lead to:

    • Hold-ups in handling documents
    • System errors or form rejection
    • Delays in salary or benefit payments
    • Cross-border hiring compliance risks
