Thanks for asking!
Before you can get started, the United States Postal Service requires a completed 'NCOA Link Processing Acknowledgement Form (PAF)' prior to accessing the NCOA Link service. Please complete, sign and be prepared to send this form to us when you are prompted by our team.
We encourage you to sign up for a DOTS NCOA Live trial key and once we have the completed PAF, we will issue you an API trial key for the service.
No credit card is required to sign up for a key.
