Python valid values?

I am trying to fix older code someone wrote years ago using python. I believe the "\d\d\d\d" refers to the number of text characters, and 0-9A-Z limits the type of input but I can't find any documentation on this. 

idTypes = {"PFI":"\d\d\d\d",
       "VA HOSPITAL ID":"V\d\d\d",
       "CERTIFICATION NUMBER":"\d\d\d-[A-Z]-\d\d\d",
       "MORTUARY FIRM ID":"[0-9]",
       "HEALTH DEPARTMENT ID":"[0-9]",
       "NYSDOH OFFICE ID":"[0-9]",
       "ACF ID":"AF\d\d\d\d",
   "GENERIC NUMBER ID":"[0-9]",
       "GENERIC ID":"[A-Za-z0-9]",
       "OASAS FAC":"[0-9]",
       "OMH PSYCH CTR":"[0-9A-Z]"}

Like the PFI values seem to be limited to 4 numeric digits in a string field, so 12345 doesn't work later in the code but 1234 does. Adding another \d doesn't appear to be the answer.

These are, apparently, regular expressions used to validate inputs. See https://docs.python.org/2/library/re.html

Without seeing the code that uses these values it is impossible to say more.
