The recent inclusion of air in-bonds into ACE Multi-Modal Manifest (Ocean, Rail and Truck) has caused an issue with providing high volume air in-bond users the range of in-bond numbers required. To resolve this the air trade entities and CBP propose changing the way a valid 9 digit number’s check digit is calculated to add a plus 1, 2 or 3 on to the MOD 7 check digit. If not identified as one of these Air high volume in-bond please continue to use the current nine digit in-bonds with a MOD 7 check digit. Due to this change a note in the Instructional Guidelines (IGs) for the Air CAMIR, the In-bond CATAIR, the ACS Cargo Release and the ACS Entry Summary to include this format have been made and posted to the website. If your programing validates the in-bond number you may need to make change to include this as a valid in-bond number. No ACE documentation for ACE Entry Release or ACE Entry Summary was require because they do not note how a valid in-bond number is formulated. Here is the valid air in-bond formats with the changes in red:



There are three valid formats for an in bond number. They are:



CBP assigned IT Number: The standard IT number as it is shown on the CBPF-7512E (Transportation Entry and Manifest of Goods Subject to CBP Inspection and Permit) consists of nine numeric positions; the last position is the check digit which must be calculated.



The method of calculating the check digit is MOD 7. To determine the check digit for a nine digit IT number, the first eight digits of the in bond number are divided by seven and the whole number remainder is the check digit. Note: The check digit is not the decimal but the whole number remainder from long division.



For example, the check digit for CBP assigned IT number 82345678 is calculated as follows: 82345678/7 = 11763668 plus a remainder of 2. The complete IT number is reported as 823456782.



There have been trade entities identified as high volume in-bond number users and in order to provide the range of in-bond numbers required for them the nine digit number check digit has been changed to add a plus one, two or three to the MOD-7 check digit. If not identified as one of these large volume in-bond number users utilize the check digit as MOD 7.



AMS Paperless Master In Bond Number: The AMS carrier assigns this number to freight moving under the paperless master in bond program. The first position of the number is constant. Positions 2 through 10 are alphanumeric. The last position is the check digit and is calculated using the same formula as the entry number. Refer to Appendix E of this publication for information on the computation of the entry number check digit.



Air Waybill Number: The air carrier assigns the air waybill number.



This number consists of an 11 position numeric code. The first three positions identify the air carrier, the next seven positions are a sequential number, and the last position is a check digit.
