It looks like you can't avoid pandas from trying to convert numeric/boolean values in the CSV file. Take a look at the source code of pandas for the IO parsers, in particular functions _convert_to_ndarrays, and _convert_types. https://github.com/pydata/pandas/blob/master/pandas/io/parsers.py

You can always assign the type you want after you have read the file:

df.phone = df.phone.astype(str)
