Pieces not claimed at an automation price must not be marked “AUTO” unless single-piece postage is affixed or a corrective single-piece price marking is applied under 188.8.131.52.
When preparing full trays, mailers must fill all possible 2-foot trays first; if there is mail remaining for the presort destination, mailers must use a combination of 1-foot and 2-foot trays that result in the fewest total number of trays for that presort level.
Barcoded tray labels required (235.4.0).
Trays sleeved and strapped (235.3.0). See 235.3.0 for exceptions to strapping for mixed AADC trays and mailings that originate and destinate in delivery area of same SCF.
Enter and Deposit (236)
Mailing entered at an acceptance point designated by USPS.
Traying Sequence (235.6.0)
Trays: Optional, but required for 5-digit price. 150-piece minimum to same 5-digit/scheme destination; bundling not permitted except for card-sized pieces; only one overflow tray permitted per destination.2
Barcoded Labels: Line 1: For 5–digit scheme trays, use destination in L012. For 5-digit trays, use city, state, and 5-digit ZIP Code on mail.
Trays: Optional, but required for AADC price; 150 pieces to same AADC; bundling not permitted; group pieces by 3-digit/scheme destination; only one overflow tray permitted per destination.2
Exception: After all full trays are prepared, one less-than-full tray must be prepared for any remaining pieces for the AADC of SCF serving post office where mail is verified.
Barcoded Labels: For Line 1, use L801, Column B for destination facility.
Trays: Required for all remaining pieces placed in mixed AADC trays; overflow pieces from AADC trays grouped by AADC; only one less-than-full mixed AADC tray permitted per mailing.
Barcoded Labels: For Line 1, use L201. For mail originating in 3-digit ZIP Codes in Column A, use “MXD” followed by city/state/3-digit ZIP Code in Column C.
Price: Mixed AADC
Bundling required for mailings consisting entirely of card-size pieces and for pieces in overflow and less-than-full trays. The maximum thickness for a bundle is 6 inches.
1. For the 5-digit price, prepare all possible 5-digit scheme trays, then prepare all possible 5-digit trays.
2. Instead of preparing overflow trays with fewer than 150 pieces, mailers may include these pieces in an existing qualified tray of at least 150 or more pieces at the next tray level. The price is based on the overflow tray that would have been made (i.e., pieces placed in a AADC tray in lieu of 5-digit overflow trays are eligible for the 5-digit price). Pieces placed in the next tray level must be grouped by destination and placed in the front or back of the tray. This option may be used selectively for 3-digit/scheme and AADC ZIP Codes. The overflow option does not apply to 3-digit origin trays.
3. AADC price for any AADC tray for the origin SCF area containing fewer than 150 pieces.
4. Use “5D BC” on 5-digit trays; on 5-digit scheme trays, use “BC 5D SCHEME.”
