I would like to set up a validation rule to check that there is at least two digits in the string. in Python I would go with this

NOT(REGEX(Field_Name__c, "(?=^(?:\D*\d\D*){2,}$)"))

But Salesforce seem to refuse this input for regex.

Does someone know how I would verify this.

Correct version: AAAA22AAAAA (at least 2 digits) Wrong version: AAAAAAAAAA (no digits

  • Your expression would not work. You need the {2,} after \d.

  • Do you mean like this? (?=^(?:\D*\d{2,}\D*)$) ?

The REGEX function in Salesforce formulas needs to have \ characters escaped (documentation).

I believe a straightforward formula like this should work:


This will check that there are at least two digits in sequence within the string. Your original regex may have some problems. I could not get it to match your expected input on regexr.com. I'm also making the assumption that the other characters do not matter, because your original pattern contains \D* which is 0 or more non-digit characters.

  • Sorry I forgot to mention it doesn't have to match characters consecutively, but a better exemple might be AAAAA1AAA1 or AAAAA2BBB3

I eventually went with NOT(REGEX(Custom_Field__c, "^(?=(?:\\D*\\d){2})[a-zA-Z0-9]*$"))

Thank you
