Mailer ID
A six or nine-digit number assigned by the USPS that identifies the specific business sending the mailing. Higher volume mailers are eligible to receive six-digit Mailer IDs, which have a larger range of sequence numbers associated with them; lower volume mailers will receive nine-digit Mailer IDs. To make it possible to distinguish six-digit IDs from nine-digit IDs, all six-digit IDs begin with a digit between 0 and 8, inclusive, while all nine-digit IDs begin with the digit 9.

Famous quotes containing the word mailer:
“Decade after decade, artists came to paint the light of Provincetown, and comparisons were made to the lagoons of Venice and the marshes of Holland, but then the summer ended and most of the painters left, and the long dingy undergarment of the gray New England winter, gray as the spirit of my mood, came down to visit.”
—Norman Mailer (b. 1923)
