PAF stands for Processing Acknowledgement Form and it is required by United States Postal Service to use the NCOA Link service, which is built into our change-of-address service, NCOA Live.
The PAF form is pretty straightforward to complete but we find people can get tripped on two things, including their full ZIP+4 and NAICS code. We can help - email us at support@serviceobjects.com if you need assistance.
