Regex issue

[tsoct]

I need the input to begin with 'IT' followed by 25 characters.

When I tested IT60X0542811101000000123456 for regex ^IT\[0-9A-Z]{25}$, no matches were detected.

What might be the reason?

@tsoct  Could you please try it as /^IT+.*/g 

Is this your expectation?

Yes, however the character following IT must be 25 characters in total.

[Sujatha V M]

@tsoct  /^IT+.{0,25}$/g

The 25 characters should include only uppercase or digits
