From USPS Headquarters:

Dear Customer,

I would like to inform you of issues in Brazil which have resulted in delays over the last several weeks for mailings to that country.  Following reports of delays from several customers, our office contacted Brazil Post to request details on the situation  and an estimate on when it can be expected to be resolved. 

In the response received yesterday, Brazil Post informed us the delays are the result of significant increases in inbound volumes which were 56% higher in December 2019 over the same period in 2018.  They explained “This unexpected high volumes associated with some technical transmission issues have generated an impact on the treatment and information exchange of some items. However, due to some contingency actions implemented by our operational area, the forecast for the complete regularization of these issues is the second half of February.”

We will continue to monitor the situation and provide updates as additional information is received.
