9-7 Critical Errors

9-7.1 Critical errors are signs of potentially serious problems in the system. These errors require immediate corrective action by the mailer even though they may not require postage adjustments for individual mailings.

9-7.2 The following are considered critical errors:

1. Pieces not listed on the manifest.
2. Weights understated or overstated by more than one rate increment.
3. Incorrect zone, country, or rate group claimed or used to calculate postage.
4. Errors from incorrect use of postage tables.
5. Surcharges not calculated correctly.
6. ID numbers duplicated on the manifest.
7. Any error relating to pieces for which extra services are requested.
8. Standard Mail pieces weighing 16 ounces or more.
9. Misclassified pieces.

9-7.3 The following are some general guidelines on managing situations involving critical errors:

1. Determine if the critical errors are isolated instances or are repetitive.

For example, samplings reveal a single instance of missing pieces over the course of several samplings versus missing pieces occurring over the course of several consecutive samplings.

2. Isolated errors can be managed on a case-by-case basis, but if over time isolated errors cause the Quarterly Accuracy rating to fall below minimum requirements, then the system needs to be managed according to 10-3.3.
3. Repetitive errors may require more immediate action by the business mail entry manager according 10-3.4.
1. The mailer may not be able to correct some critical errors immediately — the solution may require reprogramming or vendor service. The mailer may be required to apply a short-term solution until the critical error is corrected. Any short-term solution must ensure that correct postage and fees are paid.
2. If no short-term solution is available, it may be necessary to suspend system authorization as described in 10-3.4.
