Mussafah Postal Code: How to Find the Correct Onwani Code

Mussafah uses location-specific postal codes under Abu Dhabi’s Onwani addressing system. The correct five-digit code depends on the building or plot rather than the district name alone.

If an external form accepts 00000, it may work as a technical placeholder, but it is not the universal official Mussafah postcode. Mussafah and the official spelling Musaffah refer to the same Abu Dhabi area. For an actual address, use the postal code attached to that property’s Onwani information.

Does Mussafah Have a Postal or ZIP Code?

Yes. Mussafah addresses can include five-digit postal codes through Abu Dhabi’s Onwani system.

Searches for a Mussafah postal code, ZIP code, postcode, or PIN code usually refer to the same task: finding the postal value assigned to a particular address.

Some older online guides still state that Abu Dhabi or Mussafah has no postal codes at all. That does not accurately describe the current Onwani model, where postal codes form part of geographically structured address information.

The key is to identify the code attached to the specific location being addressed.

How Does Onwani Work for a Mussafah Address?

Onwani combines several address attributes to identify a property precisely.

Address Element	What It Identifies
Musaffah	Area or district context
Sector or community	Sub-area
Street	Road and location context
Building or plot	Specific property
Onwani postal code	Geographic postal zone
P.O. Box	Postal subscriber or arrangement

An Onwani address can include a building number, street name, city, area, and postal code. Each element performs a different function.

The postal code identifies the geographic postal zone. A sector narrows the location within Mussafah, while a building or plot identifies the individual property. A P.O. Box belongs to a postal recipient or arrangement rather than defining the property’s geographic location.

For Abu Dhabi addresses, the relevant official system is Onwani. Makani belongs to a different emirate addressing context and should not be substituted when identifying a Mussafah property.

How Can You Find the Correct Postal Code for Your Mussafah Address?

Start with the property information rather than a postcode copied from another Mussafah address.

A practical process is:

Confirm the property’s official area or sector.
Identify its street and building or plot information.
Locate the Onwani address assigned to the property.
Use the five-digit postal code shown for that location.
Confirm the result through DMT’s official address tools if necessary.

Onwani building signs can also help. Where available, the QR code on the sign provides mapped address information and directions linked to the property.

Do not infer the postal code from an M-sector number, a nearby business, a P.O. Box, or a generic 203xx postcode list. Those values may belong to another property or postal zone.

For the exact property, check the address in DMT’s official Onwani/MyLand lookup rather than copying a postal code from a nearby address.

Do Mussafah M-Sectors Have Their Own Postal Codes?

Mussafah labels such as M14, M17, M18, and M40 identify sectors or sub-areas. They help locate a property but are not themselves postal codes.

Identifier	Example	Function
Area	Musaffah	Broad locality
Sector	M14 / M18	Sub-area
Building or plot	Property-specific value	Exact property
Postal code	Five-digit Onwani value	Geographic postal zone
P.O. Box	Recipient-specific number	Postal arrangement

A postal code seen at one address in M14 does not automatically apply across all of M14. The same applies to other M-sectors.

So a query such as “Mussafah M18 postal code” still needs to be resolved through the individual property’s Onwani address rather than the sector label alone.

What Do 20319, 20348 and Other 203xx Codes Mean?

Several 203xx values appear in real Mussafah address data.

Code	Evidence Context	Safe Interpretation
20319	Onwani-formatted Musaffah address	Verified Mussafah postal-code example
20348	Musaffah / Al Bees-area address data	Location-specific postal-code evidence
20305	Mussafah address data	Location-specific example
Other 203xx values	Musaffah and nearby industrial contexts	Confirm against the exact Onwani address

A strong example is:

354, Al Mantaqah As Sina’iyah 1 St, Musaffah, Abu Dhabi 20319

Its components are:

354: building number
Al Mantaqah As Sina’iyah 1 St: street
Musaffah: area
Abu Dhabi: city and emirate context
20319: postal code used in that address

This proves that genuine five-digit postal codes are used in Mussafah, but only establishes 20319 for that address context.

The wider 203xx range also appears in Abu Dhabi Industrial City and other industrial locations. A common numeric prefix therefore does not prove that two properties belong to the same locality or postal zone.

How Do ICAD and Shabiya Relate to Mussafah Postal Codes?

Some places commonly associated with Mussafah need additional geographic clarification because everyday names do not always match official address entities.

Does ICAD Use the Same Postal Code as Mussafah?

KEZAD identifies ICAD 1 through ICAD 5 within the KEZAD Musaffah economic-zone structure.

That relationship does not create one postal code shared by all ICAD and ordinary M-sector properties. Each ICAD facility has its own property location and Onwani address.

Use the postal code assigned to the specific ICAD property rather than inheriting a code from another Mussafah location.

Is Mussafah Shabiya in the Same Postal Area?

“Mussafah Shabiya” is common in everyday speech and search queries, but the official address may use a different area name.

Abu Dhabi government information can place ME-sector locations under Mohamed Bin Zayed City rather than industrial Musaffah. A property described informally as being in Mussafah Shabiya may therefore have an Onwani address tied to another official area or community.

For Shabiya and ME-sector properties, use the official Onwani area shown for the address rather than assuming that an industrial Mussafah postcode applies.

Is 00000 the Mussafah Postal Code?

No. 00000 is not the universal official postal code for Mussafah.

Some external websites and forms may accept it as a technical placeholder when their address fields require a numeric postal value. That reflects the form’s validation rules, not the property’s geographic assignment.

When the correct Onwani postal code is available and appropriate for the form, use that value.

If a website requires a postal value but does not handle your UAE address correctly, see how to deal with a UAE form that requires a postal-code value.

What About 51133, 4422 and Other Mussafah Codes Online?

Some numbers associated with Mussafah come from business-address datasets or secondary postcode pages rather than authoritative DMT geographic assignments.

Number	Evidence	Correct Treatment
51133	Appears in genuine Mussafah-related address data	Real-world usage, but not proven as a universal Mussafah postcode
4422	Appears in secondary postcode claims	No authoritative DMT locality assignment found
Other copied values	Postcode lists or databases	Verify against the property’s Onwani address

51133 shows why evidence type matters. A value can appear in real or government-hosted address data without that dataset establishing it as the geographic postcode for the wider district.

The evidence for 4422 is weaker because no authoritative DMT assignment tying it to Mussafah was identified.

Official Onwani information should take priority over copied postcode lists.

What Is the Difference Between an Onwani Postal Code and a P.O. Box?

The distinction is location versus recipient.

An Onwani postal code identifies the geographic postal zone associated with a property. A P.O. Box belongs to the person, company, or organization receiving postal mail.

Two businesses in the same Mussafah area can therefore use different P.O. Boxes while their physical properties are described through Onwani.

A P.O. Box found in a company address should not be generalized to nearby properties or used as the geographic postcode.

If your goal is to arrange postal receipt rather than identify a physical address, you can compare postal box options for receiving mail.

How Should You Write a Mussafah Address?

Build the address around the property’s Onwani information.

A practical structure is:

Recipient / Company Name
Building Number
Street Name
Sector / Official Area where applicable
Musaffah
Abu Dhabi
Exact Five-Digit Onwani Postal Code
P.O. Box where applicable
Contact Number where required

For example:

354, Al Mantaqah As Sina’iyah 1 St, Musaffah, Abu Dhabi 20319

Here, the building number, street, area, and postal code describe one specific location. 20319 belongs to this address example and should not be copied into another Mussafah address simply because the locality name is the same.

Common Questions About Mussafah Postal Codes

What Is the Postal Code for Mussafah Abu Dhabi?

Use the five-digit postal code assigned to the property’s Onwani location rather than one district-wide value.

Is 20319 the Postal Code for All of Mussafah?

No. 20319 is a verified example for a specific Musaffah address.

Is an M-Sector Number a ZIP Code?

No. M14, M18, and similar labels identify sectors, while the postal code is a separate address attribute.

Which Postal Code Should You Use for a Mussafah Address?

Use the five-digit postal code shown in the property’s Onwani address. Do not substitute an M-sector number, P.O. Box, technical placeholder, or code copied from another Mussafah property.

If the address is uncertain, confirm it through official DMT address information before using the postal value.
