Regex find specific format of numbers in a string in email body

Hi all,

I’m trying to iterate through some emails in outlook. I want to trigger an email to send if one of the emails contains a specific format of numbers in the body. The format of numbers will look like this:


It will always start with 2020 and the # signs will always be unique digits. The underscore and single quotation marks are also always included.

I need some help determining the regular expression to use in my is Match activity to find that. I’m a beginner and do not much have any experience with regular expressions.


give a try on (2020\d{4}_\d{4})
here you can do some experiments with RegEx


Perfect, thank you!
