rodchar,

I don't know about your area code problem, but I do know that phone numbers
should not be stored in numeric fields.

Things like phone numbers, social security numbers, etc are really character
strings, not numeric values.

Long term you will have nothing but problems storing these values in numeric
data types.

I agree 100% only store fields as numeric values if you plan on
performing mathematical functions on them.

That being said

Dim newPhone as string

newPhone = CType(oldPhone, String)
if newPhone.length = 7 then
newPhone = "123" & newPhone
end if
oldPhone = CType(newPhone, Integer)

Your main problem will be knowing what area code to prepend to the
phone number. You will have to lookup the exchange by city and state
to find the area code. Some exchanges can be part of different area
codes too.

Here's some additional inforamtion regarding Area Codes, but these
apply to North America.

You will need to have a area code database. On our dialer product, we
actually subscribe to a service that sends us area code updates... With
that, we are able to take the zipcode and look up the area code. This
way, numbers without area codes can still be dialed (most of the time
