The two digits are the fiscal year (starts on Oct 1, ends on Sep 30) in which USCIS received the petition. 

Example: “18″ means that the petition was received between Oct 1, 2017 to Sep 30, 2018.   Note that the government fiscal year runs from October 1st until September 30th.

Working Day Number

The three digits represent the working day during the current fiscal year on which the receipt was processed and the fee was taken. 

Example: Above application was received on 249th working day of the fiscal year starting counting from October 1st. Check yourself on time and date calculator.

USCIS Case Number

The last five digits are unique sequential number (kind of counter). if you file two applications like H1B and H4 together, you might see these 5 numbers in sequence.

USCIS also uses a different receipt number generation number system that does not match with the above logic for some types of EAD and I130 applications. We do not the logic behind those receipt numbers. There is no need to worry and receipt numbers are perfectly legal.

    The logic doesn’t seem to be working anymore. For example SRC1917050248. The case is approved but if you consider the number 170 ,the date is June 6th which is yet to come . Seems like there is some other logic behind this.

      It is possible that USCIS has changed the receipt number generation logic.

      Infact, for many types of applications, they do not use this date and working day system anymore.

    There are a lot of cases where working day number is greater than 248. Like 901, 902 and so on. What would these numbers mean?

      If the number is greater than 248, then USCIS is using a different system for those receipt number. We do not know the details of that system yet and it is used for only some type of applications.
