Regular Expression for a max of 3 letters (both cases) followed by any # of digits

Question

I need some help with regular expression as I'm learning it more. Basically I want to be able to find cases where there is a max of 3 letters (both cases) followed by any # of digits.

Here are some scenarios:

AB1234 (OK)
ABC123 (OK)
AB12D3 (Error)
123AB (Error)

Thank you!

@Nick you're right - I linked the incorrect one by accident. — VLAZ, Apr 06 '20 at 23:07

This should work:

[A-Za-z]{1,3}[0-9]+
