Tonight at midnight, USPS will transition to its new Address Validation API.

We have been assured that there will be no disruption to service. However, our team will be actively testing and monitoring the service throughout the changeover to ensure everything continues to operate properly.

If you experience any issues with address validation after the transition, please let us know immediately so we can investigate.
