Abu Dhabi Postal Code: What to Enter and How Addressing Works
Abu Dhabi uses location-based postal or sector codes in some address listings, along with P.O. Box numbers and Onwani for mail handling. Common codes include 20000 for Abu Dhabi City, 20008 for Al Reem Island, 20009 for Khalifa City A, 20014 for Yas Island, and 20048 for Abu Dhabi International Airport. For form fields, 00000 is the standard placeholder code, while real delivery details usually come from a P.O. Box or an Onwani building address.

What Abu Dhabi uses instead
- Onwani is the emirate’s smart addressing system. It gives each building a unique address and includes the building number, street name, city name, area and postal code.
- P.O. Box numbers are still the main way to receive mail. They belong to a person, company or organisation rather than a street address.
- QR codes on building signs can point people to map details and directions, which makes it easier to find a specific location.
- AE-02-123 is an example of the address format used with Abu Dhabi’s system, combining country code, emirate code and a local number format.
For residents and businesses, the practical choice is often not a ZIP code at all, but the right P.O. Box or the correct Onwani address. That matters most when registering deliveries, writing shipping labels or completing forms that expect a conventional postcode.
How to get postal code
Abu Dhabi does not issue a traditional citywide postal code, so there is no official ZIP to request from a local post office. If you are filling in a form for a property, check whether the website wants an area code, a P.O. Box or a generic placeholder. For actual mail handling, the usual answer is your P.O. Box number or the Onwani address assigned to the building.
When in doubt, check the sender’s requirements before using an area code like 20000 or a fallback such as 00000. Businesses, landlords and property managers may also provide the correct Onwani details for deliveries, especially in newer districts or multi-tenant buildings where street-style addressing is more useful than a postal code alone.
What to enter on forms
Many international websites still require a postal code field even when the destination is Abu Dhabi. In those cases, enter the site’s accepted placeholder, such as 00000 or N/A, because Abu Dhabi does not use a traditional postal code system.
- Enter 00000 if the form requires only numbers.
- Use N/A if the field allows text.
- Use 12345 or 99999 only if the system rejects 00000.
- Use your P.O. Box number when the form is built for mail delivery.
Some online systems also accept the unofficial placeholder 51133, but it is deprecated and should not be treated as a standard postal code.
How P.O. Boxes work
P.O. Box mail in Abu Dhabi is addressed to the recipient’s name, P.O. Box number, Abu Dhabi, United Arab Emirates. That format directs mail to a mailbox instead of a street address and remains the standard option for personal, business and government mail collected through postal services.
People usually rent a P.O. Box from the postal system on a yearly basis. It is useful when you need a stable mailing address, especially if a building has many tenants or if the form or courier service is designed around mailbox delivery rather than street delivery.
Why Onwani matters
- It gives each building a unique address instead of leaving people to describe locations informally.
- It links buildings, streets and areas into one system for navigation.
- It supports mail delivery and logistics by making destinations easier to identify.
- It improves everyday wayfinding because QR codes on building signs can lead to map details and directions.
Onwani was introduced in 2021 and gives each building a unique address across the emirate. It is now part of Abu Dhabi’s address system for navigation, delivery and logistics.
