Being in a possession of an Alien Registration Number is certainly not the equivalent of citizenship, but it is an important first step for immigrants that want to legalize their stay and work in the U.S. Most people received their Alien Registration Numbers when they applied for a Green Card, which is, in turn, physical confirmation of their permanent resident status.
It is important not to confuse an A-number with the United States citizenship number (‘Certificate number’), which appears on The Certificate of Citizenship – a confirmation of the finalization of the naturalization process and is generally a red 6- to 8-digit alphanumeric number (reminder: A-number is a 9-digit number).
The process of obtaining an Alien Registration Number for immigrants consists of filing a number of forms.
For example, if you want to get a permanent resident card (Green Card) you need to fill in an online immigration form. There are two online immigrant visa forms:
DS-260, Immigrant Visa and Alien Registration Application
DS-261, Online Choice of Address and agent

We are well aware that any sort of immigrant registration in the U.S., be it permanent residence or work authorization is a process that requires a designated amount of time and effort, contacting immigration services (USCIS) can be stressful, especially if you have trouble speaking English or are simply intimidated by the complexity of the official forms.
