Quick Guide to Error Thresholds

Error Thresholds were established for the Full-Service Electronic Verifications, Move Update, Seamless Acceptance, and eInduction programs by using error data from all mailers participating in those programs. These error thresholds were set at an achievable level as demonstrated by mailers within the mailing industry who were participating in the programs.

The Postal Service sets these error thresholds through a periodic statistical analysis of quality for all mailings in a defined time period. The Postal Service determines both the mean (average) and the standard deviation for each error type at the eDoc submitter CRID level. The error threshold for each error type was set to at least one standard deviation from the mean.

For each individual error type within a program (Full-Service, Move Update, eInduction, Seamless Acceptance), data is pulled from all participating mailers. Each mailer, as represented by an individual CRID, had an error percentage determined by each error type in each month if they were actively participating in the program. For example, CRID 123456, which submitted Full-Service mailings but not eInduction mailings would have an error percentage for each of the three months for barcode uniqueness piece error, an error percentage for STID Errors, but not an error percentage for eInduction Misshipped Errors. Error data is aggregated solely across an eDoc submitter CRID. There is no data aggregation by MID, Permit, or Mail Owner used in setting error thresholds.

Below are the current error type and corresponding error thresholds for each program.
