REGEX to search for specific User ID


What is the syntax to find, for example, a specific User ID using regex? All of the documentation provided gives examples of finding a range of User ID’s but not a specific one. When I tried to input, for exmaple, /^1645$/ which is one way of doing it, there are zero results returned but that User ID does exist. Also tried \b1645\b but that doesn’t work, either.

Thank you.


To find, for example ONLY the subscirber id 1526 use:


in the Subscriber ID REGEX expression tool.
