When you file an application, petition, or a benefit request with US Citizenship and Immigration Services (USCIS), they issue a receipt notice indicating that your application was received by them on a particular date and they are processing it. As part of the receipt notice, there is a ‘Receipt Number’ that can be used to check the USCIS Case Status online. There are various components that make up the USCIS ‘Receipt Number’. In this article, we will look at what are those components in the USCIS receipt number, what they mean, and how you can use them for tracking your case, including common FAQs.
Before we get into the details on the format of a USCIS receipt number, let’s briefly look at what is USCIS Receipt notice is, how it looks, and where to find the receipt number.
What is USCIS Receipt Notice? How does it look?
USCIS Receipt Notice is a document that is generated by USCIS after they receive an application, petition, or benefit request with them. USCIS only generates receipt notice for applications that meet basic criteria. If some of the basic requirements are not met, they usually reject the application and return the application package back to the applicant.
The USCIS Receipt notice generated is sent to applicants as ‘Form I-797C, Notice of Action‘. The top of the receipt notice indicates this form number and details. The I-797C form generated has an indication on it that says ‘Notice Type‘ as ‘Receipt Notice‘, which confirms that it is a USCIS Receipt Notice.
The Receipt notice also has details about the application or case type, the received date, receipt number, applicant name, and other important information. The applicant or attorney, who files the application with USCIS gets the physical copy of the receipt notice mailed to them. Below is a sample of how a Receipt Notice Looks. It is a sample receipt notice for an H1B Visa petition that was filed with USCIS.

These three letters are nothing but short forms for the USCIS Service Center that the filed application or petition is processed at. Below are the short forms and their corresponding service center names.

USCIS Fiscal Year
The next two digits (from left, XXX—XX—XXX—XXXXX ) after the first 3 letters indicate the ‘Fiscal Year’ when the petition or application was filed with USCIS. The fiscal year for USCIS starts from Oct 1st and ends on Sep 30th of next year. For instance, USCIS Fiscal Year 2022 would start on October 1st, 2021, and end on September 30th, 2022.
- For example, If you have the receipt number that says EAC2112850345, it means your petition was application was filed in USCIS Fiscal Year 2021, which started on Oct 1st, 2020 and ends on Sep 30, 2021.
Computer Working Day from USCIS fiscal year start date.
In most of the cases, the next three digits (from left, XXX—XX—XXX—XXXXX ) after the first 5 letters indicate the computer working day when the application or petition receipt number was generated. The computer working day is counted from the start date of the USCIS Fiscal Year, which is October 1st. The computer working day is counted excluding the weekends and holidays.
Below are some of the examples of the Computer Working day
- If your application was filed with USCIS on October 1st, it would be 001. It would look like EAC2100150345
- If it is like October 20th, it would be about 14th working day and say 014. It would look like EAC2101450345
- If we are looking at April 8th, it would be 128. It would look like EAC2112850345 Total there are 135 week days and 7 are Federal Holiday between Oct 1st and April 8th. So, you subtract 7 from 135 (135 -7 = 128), that’s how we get 128. You can use wolframalpha website to know weekdays count kind of queries
In some cases, you may not see the computer working day and see something different. For example, see the case number WAC2190000001. If you see 900 in here does not correspond to a computer working day. This is a real case number shared by users. So, some exceptions do happen for some case types.
Actual Case Number of USCIS Application or Petition
The last five digits (XXX—XX—XXX—XXXXX ) indicate the actual Case Number assigned to the application or petition that you filed with USCIS. This number is generated based on a host of factors like Case Type, Location, and then a sequence number on that particular date.
There is no publicly available information on what each of the case types would start with or how they get generated by the service center. Usually, for H1B Visa petitions, that are filed using form I-129 you would start with a number 5. For example, in case number EAC2112850345, the 50345 is the case number and 5 indicates it could likely be an H1B Receipt number. Read more at H1B Receipt Number Format, What it means
Most of the applications or petitions do get a receipt number, if they are accepted by USCIS. But, some of the submissions like H1B Registrations do not get a receipt number. Also, you do not get USCIS Receipt Number for service requests or submissions like Address Changes AR-11 Form
No, they are not the same. USCIS Online Account Number (OAN) is a unique number assigned only for certain online forms. It is also called as USCIS ELIS Number. You cannot use USCIS Online Account Number to track application case status.
