Reading time: ~2 minutes

The alien registration number, often referred to as the "A-number" or simply "alien number," is a unique identifier assigned to non-citizens by the United States Citizenship and Immigration Services (USCIS). This crucial number plays a significant role in the immigration process and is essential for various immigration-related procedures.

What is an Alien Registration Number?

An alien registration number is a seven to nine-digit code preceded by the letter "A." It serves as a personal identifier for non-citizens in the U.S. immigration system. This number is assigned to individuals when they apply for certain immigration benefits or come into contact with immigration authorities.

Importance of Your A-Number

Understanding what your A-number is and where to find it is crucial for several reasons:

  1. Identification: It's your unique identifier in the immigration system.
  2. Documentation: Required for filling out various immigration forms.
  3. Status Tracking: Helps in checking the status of your immigration applications.
  4. Record Keeping: Allows easy access to your immigration history.
