I have a column of zip codes which are strings. Most of them are the usual 5 digit zip codes, but some are only 3 digits or missing a digit. (keep in mind, I need this column as strings for other reasons)



I basically want to select everything that has less than 5 characters for further investigation. I'm sure there's an easy way to do this, but I'm having a difficult time figuring it out.

    Awesome, glad it worked! Will post it as an answer for the convenience of others :) – Joseph Dec 21 '15 at 15:03

Using the Select by Attributes tool, you could enter the following SQL query to select all features with less than 5 characters in the ZIP field:


you could also use

Left("ZIP", 5)

to select features with 5 digits.

    This will return the first 5 characters of any attribute but has little relation to the length of the attribute. – raphael Feb 7 '16 at 7:15
