Postal Codes and Zip Codes in Abu Dhabi (2026): Your Complete Onwani Guide

Have you ever tried to fill out an online form and paused at the “Zip Code Abu Dhabi” field? You’re not alone. Abu Dhabi’s Department of Municipalities and Transport (DMT) has rolled out Onwani, a modern addressing system that names streets, numbers buildings, and includes a postal code reference to make navigation and deliveries straightforward for residents, schools, and businesses across Abu Dhabi, Al Ain, and Al Dhafra.

What is a postcode?

A postal code (also called a ZIP code) is a short series of numbers or letters added to a mailing address to help postal and courier services sort and route deliveries efficiently. Many international websites ask for a postal code even when local delivery systems work differently.

What is the Onwani System?

The purpose of the Onwani system is to name streets and number buildings and facilities in Abu Dhabi to facilitate access to any site within the emirate. This evolving system is aligned with global best practices for addressing and local guidance. Street names reflect local heritage and culture to enhance national identity and connect this generation to the UAE’s history. This official address information is linked for use by public and private service providers across Abu Dhabi, supporting navigation, emergency response, and last‑mile delivery.

What are the Addressing Components?

Abu Dhabi’s standardized address includes the following elements as they appear on Onwani signage and within the system:

• Building number (unique identifier on the blue address plate)
• Street name
• Area or district
• City (Abu Dhabi, Al Ain, or Al Dhafra region city)
• Postal code (as referenced within the Onwani system where applicable)
• QR code on the building sign that opens the precise location and directions

Individuals can scan the QR code found on the building’s sign to find its location on a map and directions, with the ability to share the pin or full address easily.

What are Benefits of the Addressing System?

Onwani delivers everyday benefits to residents, parents, schools, and businesses:

• Reduces travel time and improves wayfinding for visitors, taxis, deliveries, and school transport.
• Speeds up emergency response by providing precise, consistent location data.
• Strengthens logistics and e-commerce delivery success rates across the emirate.
• Improves public services and urban planning through accurate address data.
• Supports better business operations, marketing, and customer contactability.

How to Find Your Address By Using Onwani System

Please click on any location on the map or search for a plot or building to find your address details. You can also search for any location and address by using the search field in the system. For more details, please click here.

Step-by-step: find your Onwani address and postal code

• Open the official Onwani map or the TAMM Abu Dhabi portal/app.
• Use the search bar to enter your building number and street name, a landmark, or your area/district.
• Click directly on your building on the map to display the full address card.
• Scan the blue plate’s QR code on-site to open the same address card on your phone.
• Copy the full address lines shown, including the postal code reference where available, and share them with couriers or on online orders.

Tip: Save the address card to your phone notes and share it with your child’s school, school transport, or frequent delivery apps for fewer missed deliveries.

How to write your Abu Dhabi address correctly

Use your Onwani details as the primary address for couriers and e-commerce. Include a PO Box only if you want Emirates Post mailbox delivery.

Standard courier/home delivery format (Onwani)

Recipient Name

Building [Number], [Street Name]

[Area/District], [City], Abu Dhabi

Postal Code: [Your Onwani postal code if shown]

United Arab Emirates

Mobile: +971 [your number]

Post office delivery (PO Box)

Recipient Name

PO Box [Your Number], Abu Dhabi

United Arab Emirates

Mobile: +971 [your number]

Note: Emirates Post delivers to PO Boxes unless you subscribe to a home delivery service. Many international retailers and express couriers deliver directly using your Onwani address without a PO Box.

What to enter in the “Zip/Postal Code” field on online forms

• Best practice: Enter the Onwani postal code shown with your address when available.
• If a website insists on a postal/ZIP code but you do not see one in Onwani, many platforms accept 00000 as a placeholder for Abu Dhabi.
• Always include your full street address, building number, area, city, and a reachable UAE mobile number to ensure successful delivery.
• For PO Box deliveries, add “PO Box [number]” in Address Line 2 and keep your city as “Abu Dhabi.”

Onwani vs. PO Box vs. Makani: what’s the difference?

• Onwani (Abu Dhabi): Street naming and building numbering system that supports navigation and deliveries; address plates include a QR code and system-backed postal code reference.
• PO Box (UAE-wide): A mailbox rented from Emirates Post; mail addressed to your PO Box is held for pickup or forwarded if you use additional services.
• Makani (Dubai): A separate system used in Dubai that assigns a 10‑digit Makani number to every building entrance for precise location; not used in Abu Dhabi.

For Abu Dhabi deliveries, prioritize your Onwani address. Use your PO Box for traditional mail or when a sender requires it.

Practical tips for families, schools, and small businesses

• Share your Onwani QR code with school transport providers to reduce pickup delays.
• Add your full Onwani address to your business website, Google Maps listing, invoices, and delivery instructions.
• For international shippers unfamiliar with Onwani, include a landmark in Address Line 2 (e.g., “Near [Landmark]”) plus your mobile.
• If a courier calls for directions, reference the building number and street exactly as shown in Onwani; avoid unofficial nicknames for areas.
• Moving home? Update your address everywhere: school records, banking, delivery apps, insurance, and utilities.
