We haven't been able to purchase our shipping labels for about a week now. We go through the process to purchase but when we get to the "Ready to Print" window, we see this message:
This is the error message we've received back from USPS:
LABEL FAILED! Invalid SOAP message due to XML Schema validation failure. The 'http://stamps.com/xml/namespace/2018/10/swsim/swsimv76:ZIPCode' element is invalid - The value '10011-2471' is invalid according to its datatype 'http://stamps.com/xml/namespace/2018/10/swsim/swsimv76:string-0-5' - The actual length is greater than the MaxLength value.
All was fine when we were hooked up with USPS and Endicia.
