Alien Registration Number or A-number is an eight or nine-digit unique identification number provided to immigrants of the United States.
Immigrants like permanent residents and people who come to the U.S. through immigrant visas get an A-number. It is used by the U.S. government to track all the immigration forms and petitions that you may apply for the years to come.
This alien registration number is not provided to non-immigrants like b1 visa holders, b2 visa holders or tourist visa holders who are coming to the United States temporarily.
This alien registration number is required when filling out forms for Green Card Renewal (Form I-90), U.S. citizenship (Form N-400), employment authorization (Form I-765), and more. If you are looking to prepare any immigration forms then check out our immigration form preparation services.
When filling immigration forms, the Alien registration number is required in 9 digits. However, older green cards or older numbers could be just 7 or 8 digits.
If your Alien Registration Number is less than nine digits, for example, if it is an 8 digit number you can insert a zero before the first digit to create a nine-digit number. For example, “12345678” would become “012345678” then you can use it in the forms you may file.
This number is also referred to as an A-number or USCIS number or USCIS# without a case. It is not the same as your case number or permanent resident card number.
