You can find either the alien number or I-94 number in Section 1 of the employee’s Form I-9. An alien number (referred to on Form I-9 as alien registration number/USCIS number) may contain between seven and nine digits while an I-94 number (referred to on Form I-9 as a Form I-94 admission number) is an 11-digit number.
Alien numbers, also called alien registration numbers, USCIS numbers, or A-numbers are identification numbers issued to noncitizens by U.S. Citizenship and Immigration Services (USCIS).
Enter the alien number as indicated on the employee’s Form I-9. Do not enter the alien number with a preceding A. While alien numbers may consist of between seven and nine digits, you must enter exactly nine numeric characters in E-Verify. For alien numbers with fewer than nine digits, add one zero (0) to the beginning of an eight-digit alien number and two zeroes (00) to the beginning of a seven-digit alien number. For example, if the employee’s alien number is A1234567, enter 001234567 in E-Verify. You may not enter any letters or special characters.
Following are examples of U.S. government-issued documents that contain alien numbers and where alien numbers can be located on these documents.

The USCIS number listed on the front of Permanent Resident Cards (Form I-551) issued after May 10, 2010, and circled below, is the same as the alien number except it does not contain the A prefix before the number. The alien number can also be found on the back of these Permanent Resident Cards and is also circled below.
I-94 numbers, also called admission numbers, are printed on Arrival/Departure Records (Form I-94 or Form I-94A) issued to nonimmigrants by U.S. Customs and Border Protection (CBP) and U.S. Citizenship and Immigration Services.
Enter the I-94 number as indicated on the employee’s Form I-9. You must enter exactly 11 numeric characters. You may not enter any letters or special characters.
Important: If Section 1 of the employee’s Form I-9 contains both an I-94 number and a foreign passport number, you must enter the foreign passport number in the field Foreign Passport Number from Section 1 of Form I-9.
