<p dir="ltr">When submitting a US immigration application, you will come across a term called "A number". It is a vital piece of information but are you wondering where to find an A-number? Who gets an Alien registration number and why is it important? In this blog, we will cover everything you need to know about the A-number. Such as its use, how to find it, and why it is important for immigrants in the US. Let's first understand what an Alien Registration Number is.</p>
<h2>What Is an Alien Registration Number (A-Number)?</h2>
<p dir="ltr">An Alien Registration is a seven to nine-digit number. It is also known as "A-number, Alien Number, or USCIS number. The US Citizenship and Immigration Services (USCIS) gives an A-number to those immigrants who apply to live in the United States. The USCIS uses your A-number to track your immigration files which are also called alien files or a- files. They also need you to submit your Alien number on most immigration documents you provide to them.</p>
<p dir="ltr">It is an important key to accessing various immigration services and benefits when you are in the US. Many non-immigrant visitors and US citizens don't have an Alien registration number. This is because USCIS doesn't give an A-number to those who will be in the US temporarily. F-1 student visas with employment authorization who enter the US are an exception for this. </p>
<h3>Different Types of Alien Registration Numbers</h3>
<p>Most of the Alien Registration numbers (A-numbers) have nine-digit numbers. There are some situations where they may have fewer digits. If your A-number has less than nine digits then you can add a zero (0) between the "A" and the first digit.</p>
<p>This way you can make sure that it is a complete nine-digit number. For example, if the number is "33445566", you need to add "A033445566' to make it a nine-digit number.</p>
<h2>Why Is an A-Number Important?</h2>
<p dir="ltr">The A-number is used throughout the immigration process. It helps the govt. to track a person's immigration history and status throughout their life in the US. An Alien Registration Number serves as an important identifier for a lot of reasons such as:</p>

<ul>
<li><strong>Legal Identification - </strong>The A-number acts as an official government-issued identifier for non-citizens. It is more like a Social Security Number (SSN) for US citizens. It helps in streamlining the communication between various immigration agencies.</li>
<li><strong>Immigration Case Management -</strong> This number helps the USCIS, Immigration and Customs Enforcement. Also, the Executive Officer in Immigration Review (EOIR). It is required to manage case records and legal proceedings effectively.</li>
<li><strong>Tracking the Application -</strong> The US govt uses the A-number to monitor everyone's immigration applications, petitions, and case studies. You can find this number on various important documents. Such as green cards, employment authorization cards, and visa paperwork. </li>
<li><strong>Verifying the Eligibility -</strong> Some government agencies and employers may also use the A-number. They use it to verify one's eligibility to work and social security benefits. Also, to check any and other federal services. </li>
