[0-9]{0,5} for up to 5 characters but can be less

[0-9][0-9][0-9][0-9][0-9]  simple 5 characters

/\d{5}/  for 5 digits   11111 will match but 1, 11, 111, 1111,  will not nor anything > 5

[0-9]{5] for five digits  save as the above


[0-9]{0,5}  <-- this can be nothing, 1, 11, 111, 1111, 11111, but not > than 5
