Struggling to find the right regex

Question

I'm struggling to find the right regex to validate an input.
I need a regex to match an alphanumeric string which ends with 9 digits, no more, no less.
All the spaces and special characters are stripped before the check, they don't matter here.

Examples of what I need :

SHOULD MATCH :

perpignan123456789
DEINOjeonfjuefz123456789
a123456789
123456789

SHOULD NOT MATCH :

perpignan1234
123456789fdazda
perpignan1234567890123456

I think I'm close to the solution with : [A-Za-z]{0,}[0-9]{9}$

The problem is that it returns "true" when tested with : perpignan1234567890123456

Some help would be appreciated,
Thanks in advance :)

Use `^[A-Za-z]{0,}[0-9]{9}$`, you just missed `^` anchor to make sure the string starts with your pattern. See https://regex101.com/r/aUlMNX/1/. — Wiktor Stribiżew, Jul 04 '19 at 07:42
I can't understand your rules. Can you briefly explain them? — dganenco, Jul 04 '19 at 07:42

Try this one:

[A-Za-z]{0,}[0-9]{9}\D

OP just needs to match the whole string. No need for fancy patterns when anchors do the job. – Wiktor Stribiżew Jul 04 '19 at 08:19
