Unwanted Comma

[ARazorbacks]

I am trying to search out street address's on a county website and the iPhone automatically puts a comma in the street number if it has more than
3 digits. I have tried turning off the auto correction but that did not help. I have had 3 Blackberry phones before the iPhone and have never had this happen before. It seems to only happen with the phone. Any ideas? If anyone wants to try the website is ARCountyData.com Choose Benton county and then click for "Free Public Search for Public Assessments" Try putting in a 4 or 5 digit street.
Thanks
