ZipCityDistance error for certain ZIP codes

[thesasuser]

Hello
I am trying to run a code which givers error particular values of zipcode.

data _null_;
dist=zipcitydistance(36310,36061);
run;

The error in the log is

NOTE: ZIP code value 36310 could not be found in SASHELP.ZIPCODE.
NOTE: Invalid argument to function ZIPCITYDISTANCE('36310','36061') at line 27 column 6.
dist=. _ERROR_=1 _N_=1
NOTE: Mathematical operations could not be performed at the following places. The results of the operations have been set to 
      missing values.
      Each place is given by: (Number of times) at (Line):(Column).
      1 at 27:6   

If I change the order of zipcode in the function taking 36061 first, then the error would be

24         
25         GOPTIONS ACCESSIBLE;
26         data _null_;
27         dist=zipcitydistance(36061,36310);
28         run;

The server has been updated for the latest values of zipcodes.
Looks like I missing something. Can anybody help?

Suggest looking at the records in sashelp.zipcode to make sure the zip codes are there:

proc print data=sashelp.zipcode;
  var zip ;
  where zip in (36061 36310) ;
run ;

I have them in my data, and your code runs fine:

16   data _null_;
17   dist=zipcitydistance(36310,36061);
18   put dist= ;
19   run;

dist=41.5
