The UAE is home to two major telecom providers, Etisalat and DU, which dominate the market for mobile and internet services. With multiple number prefixes in circulation, many residents often wonder which operator a specific number belongs to. One of the most common queries is regarding the 054 prefix—does it belong to DU or Etisalat? This guide will clarify the issue and provide insights into mobile number allocations in the UAE.
Understanding Mobile Number Prefixes in the UAE
Each mobile number in the UAE starts with a three-digit prefix that indicates the telecom provider. These prefixes are assigned by the Telecommunications and Digital Government Regulatory Authority (TDRA) to maintain an organized numbering system.
Historically, Etisalat was the only telecom provider in the UAE until DU entered the market in 2006. Since then, new number ranges have been introduced for both operators to accommodate the growing demand for mobile services.

Who Owns the 054 Prefix?
The 054 prefix is assigned to DU, meaning any mobile number beginning with 054 is originally registered under DU’s network. However, due to the UAE’s number portability service, users can switch their numbers between Etisalat and DU while retaining their original prefix. This means that although 054 numbers belong to DU, some users may have ported them to Etisalat.
Complete List of Mobile Prefixes in the UAE
To differentiate between DU and Etisalat numbers, here is a breakdown of the mobile prefixes allocated to each operator:
Etisalat Mobile Number Prefixes:
- 050
- 056
- 058
DU Mobile Number Prefixes:
- 052
- 054
- 058 (shared with Etisalat)

How to Check If a Number is DU or Etisalat?
If you’re unsure whether a specific number belongs to DU or Etisalat, you can:
- Call Customer Support: Contact DU (155) or Etisalat (101) and inquire about the number.
- Use Network Services: Some services may display the operator when dialing a number.
- Check Online Portability Services: TDRA provides an online tool where users can check number portability.
Can You Switch Your 054 Number to Etisalat?
Yes, number portability allows users to switch between DU and Etisalat without changing their mobile number. If you have a 054 number but prefer Etisalat’s services, you can request a porting process by visiting an Etisalat store or using their mobile number portability service.
Choosing Between DU and Etisalat
Both telecom providers offer competitive services, and the choice between DU and Etisalat depends on factors such as:
- Coverage and Network Strength: Etisalat is known for broader coverage, while DU is more popular in urban areas.
- Pricing and Plans: DU often provides more budget-friendly plans, whereas Etisalat is known for premium services.
- Data Packages and Benefits: Each provider has unique data packages, international calling rates, and loyalty programs.
Conclusion
If you come across a 054 number in the UAE, it originally belongs to DU. However, due to number portability, it could be in use under Etisalat. Understanding the UAE’s mobile number prefixes can help identify the telecom provider and make informed choices regarding mobile services. Whether you choose DU or Etisalat, both operators offer extensive mobile and data plans to suit different needs.
