Hi C,

Unfortunately, there's no IsAlfa() function in BP, like there is a IsNumeric() function. In this case, I'd suggest using regex, an object to work with regex should already be available in you BP installation. 

It would be easiest if you split the string in the first 3 and the last 7 chars. The first 3 chars you can check using Regex. If you google 'regex check alphanumeric' or similar, you'll get many pages describing what you want to know. 

If you want to know more about regex, I'd suggest this page, or perhaps this one.

Happy coding!

Further to what @PvD_SE had said about using Regex, you can use the "Test Regex Match" action in BP's "Utility - Strings" VBO. You can use a regex pattern of:

"^[a-zA-Z]{3}[0-9]{7}$"

This will take care of both your length testing and character matching. The breakdown of the pattern is:

^ - start of the line
[a-zA-Z] - match any letter
{3} - match three of the previous specified characters
[0-9] - match any numbers (before anybody says anything, no, "\d" does not always mean the same as "[0-9]" in .Net)
{7} - match seven of the previous specified characters
$ - end of line
