I am using as SSIS package to import CSV file to Sql server table, in csv file one of the column is phone numbers, which has both international numbers and local numbers, after importing data into table ,i see that international phone numbers have plus sign in front of the number, even though i dont see any plus sign in the csv file..but local numbers are importing correctly..
What are you using to look at the CSV file? If you are using Excel, it may be masking the + sign. Look at the CSV file using Notepad and see if there is a plus sign in the source file.
