Emirates ID Number Format: What 784 and Each Digit Mean
The Emirates ID number is the 15-digit number printed on your card, written in the format 784-XXXX-XXXXXXX-X. The 784 is the UAE’s international country code, the next four digits usually relate to your year of birth, the seven digits after that are a unique reference, and the final digit is a check digit. It stays with you for life, even when the card itself is replaced.
- Your ID number is the 784 number on the front of the card.
- It does not change when you renew or replace the card.
- It is not the same as your UID or your card number.
The Emirates ID number format explained
Every Emirates ID number has 15 digits, split into four parts by hyphens. Each part does a different job, and knowing which is which helps when a form asks for a specific section.
| Part | Digits | What it is |
|---|---|---|
| 784 | 3 | The UAE’s international country code |
| Second block | 4 | Usually relates to the holder’s year of birth |
| Third block | 7 | A unique reference number for the holder |
| Final digit | 1 | A check digit that validates the whole number |
One common assumption is worth correcting. People often treat the four-digit block as a guaranteed birth year. For UAE nationals it typically is, but you should not rely on it as a birth date, and you certainly should not treat it as identity verification. It is part of a reference number, not a date field.
The final digit matters more than it looks. It is a check digit, calculated from the digits before it, which lets systems spot a mistyped number immediately. That is why an online form can reject your ID number as invalid the moment you enter it, before it has looked anything up.
Why every Emirates ID starts with 784?
The 784 prefix is not random and it is not a serial. It is the UAE’s country code under the international standard used to identify countries numerically, so every Emirates ID number issued begins the same way.
This is a useful thing to recognise. If a number claims to be an Emirates ID number and does not start with 784, or does not have 15 digits in total, it is not a valid Emirates ID number. That simple check catches most typing errors and a fair few fake documents.
Numbers people confuse it with
Three different numbers get mixed up constantly, and forms rarely explain which one they want. This is the difference.
| Number | What it is | Does it change? |
|---|---|---|
| Emirates ID number | The 15-digit 784 number identifying you | No, it stays with you |
| Card number | A number identifying the physical card itself | Yes, a new card means a new card number |
| Unified number (UID) | An immigration file reference on your residence visa | No, but it is a separate number entirely |
The practical takeaway is that replacing a lost card does not give you a new Emirates ID number. Your identity number carries over, which is why our guide to replacing a lost Emirates ID notes that the replacement is issued for the same validity period as the original.
Where to find your Emirates ID number?
The number is printed on the front of the card, in the middle section, clearly formatted with hyphens. It is the number nearly every UAE service asks for, from banks and clinics to telecom providers and government portals, including the labour checks in our UAE work and labour guide.
If you are waiting for a first card and do not have the number yet, you cannot use it to track the application. A new application is tracked with the PRAN from your receipt instead, which our Emirates ID status check guide explains. Once you hold the card, keep the number handy but treat it as sensitive: it is the key to a great many services, so do not share it casually or enter it on sites you cannot verify. For everything else ID related, see our Emirates ID guide.
Frequently asked questions
What is the Emirates ID number format?
It is 15 digits written as 784-XXXX-XXXXXXX-X. The 784 is the UAE’s international country code, the four-digit block usually relates to the year of birth, the seven-digit block is a unique reference, and the last digit is a check digit used to validate the number.
Why does the Emirates ID start with 784?
784 is the UAE’s numeric country code under the international standard for identifying countries. Every Emirates ID number begins with it. A number that does not start with 784, or that is not 15 digits long, is not a valid Emirates ID number.
Does my Emirates ID number change when I renew?
No. Your Emirates ID number stays the same across renewals and replacements. What can change is the card number, which identifies the physical card rather than you. The unified number, or UID, on your residence visa is a separate number again.
Is the Emirates ID number the same as the UID?
No. The Emirates ID number is the 15-digit 784 number on your card. The unified number, or UID, is a separate immigration file reference linked to your residence visa. Forms sometimes ask for one and sometimes the other, so check which is being requested.
