How an address is written in Hong Kong SAR China

The postal format table for Hong Kong SAR China — the order the lines go in, the parts its operator requires, what it calls them, and the words it prints on a box — and, separately, what this server actually holds for Hong Kong SAR China, so the page never implies a check it cannot run.

The order the lines go in

The parts are named rather than filled in: Spaw does not know an address in Hong Kong SAR China and will not invent one. This block is produced by the same function that rewrites a real address, so the line order, the capitals Hong Kong SAR China asks for and any text its operator prints on every envelope are the checker's own behaviour rather than a second description of it.

Organisation
12 Street name
Flat or unit
District
AREA

No recipient line: nothing in the response is about a person, so the name the envelope carries is not part of what is checked.

field	called here	required	capitals
organization	Organisation	optional	—
addressLine1	Street name	required	—
addressLine2	Flat or unit	optional	—
locality	District	optional	—
administrativeArea	Area	required	yes

No house-number rule is carried for Hong Kong SAR China, so the international default is used: the house number comes before the street name.

The table also carries a local layout for Hong Kong SAR China, and it runs the other way round: the area first and the street last. The order above is the Latin one, which is what an address rewritten here is written into.

The postal code

The table carries no postal code pattern for Hong Kong SAR China, so an address here is never marked down for lacking one and a value that is supplied is passed through unchecked. That is the honest answer: this page will not invent a format for a country that does not publish one.

No Hong Kong SAR China postcode directory is installed here, so a well-formed postal code is never confirmed to exist — only its shape is checked, and postcode_not_found is never answered for Hong Kong SAR China.

What Hong Kong SAR China calls an address that is not a front door

The words below are Hong Kong SAR China's own, taken from its postal operator's addressing guide, and they are the words the checker reads. Because they are carried, an address here with none of them answers street.

address_type	written as
private_mailbox Private mailbox at a mail-receiving agency	PMB
po_box Post-office box	PO BOX, P O BOX, GPO BOX, G P O BOX
general_delivery Held at the counter for collection	POSTE RESTANTE, GENERAL DELIVERY

A post-office box is the ordinary way to receive mail in Hong Kong SAR China, so a box here carries no risk weight at all. Scoring it would penalise almost every address in the country for being addressed the way the country addresses things.

What can be checked for a Hong Kong SAR China address

Read from the datasets this server holds right now, not written into the page. For most countries the answer is the written form and the postcode shape and nothing beyond them — in particular not the row people assume is always there. An address can be perfectly formed and still not exist, and where no register is installed nothing here will pretend to know which.

check	for HK	what the answer means
Written form	yes	The address is split into Hong Kong SAR China's own parts and rewritten in the order above. A missing required part is named in one typed reason rather than a general failure.
postal code pattern	not used here	Hong Kong SAR China has no postal code in the table, so nothing is checked and nothing is held against an address for lacking one.
postal code exists	no	No Hong Kong SAR China directory is installed, so a well-formed postal code is never confirmed or denied — only its shape is checked.
Kind of delivery point	yes	Hong Kong SAR China's own box naming is carried, so an address with no marker answers street rather than unknown.
Street exists	no	No register is installed for Hong Kong SAR China, so a street is neither confirmed nor denied: match_level answers null.
Building exists	no	No address register is installed for Hong Kong SAR China, so exists answers null: not evaluated, never no. Absence is not evidence here.
Companies at the address	no	No open company register is installed for Hong Kong SAR China, so companies_registered answers null and no mail-drop conclusion is drawn from a count.
Known mailbox branch	no	No operator branch list covers Hong Kong SAR China, so is_mail_drop is never set from one here.
Post actually arrives	no	Not from this page, and not from open data in any country: whether post is delivered, and the vacant, residential and agency flags that go with it, are the postal service's own licensed product. Those fields answer deliverability_checked: false rather than a guess.

Null means not evaluated, never no. How to read an address-existence answer sets out what a premise, street or postcode match proves, and what absence proves.
