055 Du or Etisalat – Which Network Does It Belong to in the UAE?

Have you ever come across a UAE mobile number starting with 055 and wondered whether it’s a Du or Etisalat number? You’re not alone. With multiple prefixes, number portability, and different providers operating across the UAE, it’s easy to get confused. This article clarifies which telecom company the 055 prefix belongs to, how mobile and landline numbers are structured in the UAE, and why knowing a number’s origin matters.

What Does the 055 Prefix Represent in the UAE?

In the UAE, mobile phone numbers start with three-digit prefixes that help identify the original telecom provider. The 055 prefix is officially assigned to Du, which is one of the two major telecom companies in the country alongside Etisalat.

When Du launched its mobile services in 2007, it was assigned prefixes such as 052, 055, and 058.

These prefixes are used to distinguish Du numbers from Etisalat numbers, which include 050, 054, and 056. So, if you see a number beginning with 055, it was originally issued by Du.

However, things can get complicated due to Mobile Number Portability (MNP). This system allows customers to switch from one provider to another without changing their number, including the prefix.

So while 055 usually belongs to Du, a number may currently be using Etisalat’s services if it has been ported.

How Are UAE Mobile and Landline Numbers Structured?

UAE telecommunications follow a structured numbering system that helps identify both the type of connection and the geographic origin.

Landline numbers are based on the Emirate in which they are registered. Each Emirate has a unique area code:

Mobile numbers, on the other hand, are structured differently and are based on the telecom provider. Here’s a breakdown of the major mobile prefixes:

This distinction is important for identifying the original provider and for understanding possible charges when calling between networks.

Is 055 a Du or Etisalat Number?

The 055 prefix is originally issued by Du. That means any new mobile number starting with 055 comes from Du’s number bank. This prefix has been part of Du’s services since its introduction to the UAE telecom market.

However, because of number portability, users can now switch from Du to Etisalat while keeping their original number. This means some 055 numbers may now be active on the Etisalat network. So while the number began with Du, it might not currently be serviced by them.

To determine the current provider, you will need to verify using official tools or through customer support. Relying on the prefix alone is not always reliable in today’s market.

How Can You Check if a Number Is Du or Etisalat?

Identifying the current network of a UAE mobile number is important, especially if you’re trying to take advantage of in-network call discounts or specific data plans. Here are effective ways to verify the active provider:

The most accurate way is through online verification tools offered by both Du and Etisalat. These tools allow you to input a mobile number and confirm which network currently services it.

If online tools aren’t accessible, calling the telecom provider’s customer support is a good option. Their representatives can help you confirm the network status of any UAE number.

You can also use the mobile apps provided by Du or Etisalat. If you use one of these apps for calling, texting, or checking balances, the system can automatically recognize whether a number is in-network or not.

Why Does It Matter Which Network a Number Belongs To?

While all telecom operators in the UAE provide similar services, the cost of using those services can vary depending on whether you’re communicating within the same network or between networks.

For example, some mobile plans offer free or discounted in-network calls. So knowing if the number you’re calling is also on Du or Etisalat can help you avoid unnecessary charges.

Moreover, certain promotions and packages are exclusive to each provider. If you’re sending data, messages, or making frequent calls, knowing your contact’s network can help you choose the best plan.

Another reason this matters is for customer support and service issues. When reporting issues or seeking help, you need to know which provider currently handles the number.

Can You Keep Your 055 Number If You Switch Providers?

Yes, you can. Thanks to Mobile Number Portability, users can switch from Du to Etisalat or vice versa without changing their mobile number. That includes keeping the original prefix, such as 055.

This service, regulated by the Telecommunications and Digital Government Regulatory Authority (TDRA), allows greater flexibility and promotes healthy competition among providers.

The process typically involves submitting a portability request, providing valid ID, and confirming the switch through SMS or in-store verification. Once approved, the transition usually takes one to three business days.

How Do You Call a UAE Number From Outside the Country?

If you’re trying to call a UAE mobile or landline number from abroad, it’s essential to understand the correct international dialing format.

To make an international call to a UAE number:

1. Start with the international dialing code (+971).
2. Drop the initial 0 from the UAE number.
3. Dial the rest of the number.

For example, if the local number is 055 123 4567, the international format would be +971 55 123 4567.

This rule applies to all UAE numbers, regardless of whether they are mobile or landline.

How Do Du and Etisalat Compare in 2025?

When choosing between the two main providers, users often consider coverage, pricing, customer support, and the range of packages offered. Here’s a side-by-side comparison:

While Du is generally seen as more budget-friendly and tech-forward, Etisalat is known for stability, wider rural coverage, and corporate services. The better option depends on your usage, location, and preferences.
