ACE In-Bond Sequence Search Page

A guide to automating, managing, and tracking CBP In-Bond entry numbers in BorderConnect.

Type: Software Tool Feature: Automation

Overview

The ACE In-Bond Sequence Search Page is a centralized tool used to create, manage, and track ranges of In-Bond entry numbers assigned by U.S. Customs and Border Protection (CBP).

This feature automates the complex requirement of calculating check digits and prevents duplicate number usage. It is available in both the ACE Manifest and U.S. In-Bond Manager products.

How the Workflow Works:
1. CBP assigns a block of numbers (the range) to the carrier.
2. The carrier enters the start and end of that range into BorderConnect.
3. BorderConnect automatically calculates check digits and assigns the next available number to new shipments.
4. Usage is tracked and audit-ready reports are generated automatically.

Why Use ACE In-Bond Sequences?

Using sequences reduces manual data entry errors and ensures compliance with CBP numbering standards.

Benefit	What It Does
Check Digit Generation	Automatically calculates the correct final digit required by CBP, preventing "Invalid Entry Number" rejections.
Automatic Assignment	Automatically grabs the next available number in the sequence when you create a shipment, so you never have to look up "which number is next."
Usage Tracking	Links specific entry numbers to specific shipment control numbers (SCNs) for full traceability.
Audit Reporting	Allows you to export usage history to a spreadsheet for CBP audits or internal record keeping.

Accessing In-Bond Sequences

Accessing In-Bond Sequences via the Menu

You can access the sequence management tool from three different locations in the menu, depending on your workflow:

• ACE eManifests > In-Bond Sequences
• U.S. In-Bonds > In-Bond Sequences
• Manage Data > In-Bond Sequences

Creating a New Sequence

When CBP issues a new block of numbers, you must enter them here before they can be used.

Required Fields

Field	Description
Sequence Start	The first number in the range provided by CBP (enter without the check digit).
Sequence End	The last number in the range provided by CBP (enter without the check digit).

Note: Once saved, the system will immediately begin assigning numbers from this range for any new In-Bond shipments.

Entering a New CBP-Assigned Range

Managing and Searching Sequences

The search page displays all sequences chronologically, with the most recent ranges at the top. You can filter by Entry Number, Shipment Control Number (SCN), or Date Created.

Searching Existing In-Bond Sequences

Viewing Usage Details

Clicking View on any sequence allows you to see the specific shipment history for that range.

• Correction: Fix start/end values if a typo was made during creation.
• History: See the exact Entry Number (with check digit), the date it was used, and the Shipment Control Number it was assigned to.
• Audit: Verify that no numbers were skipped or duplicated.

Viewing Sequence Usage History

Best Practices

Tip	Why It Helps
Enter Exactly as Issued	Input the range exactly as provided by CBP to prevent numbering overlaps.
Monitor Usage	Check your remaining numbers periodically so you can request a new block from CBP before you run out.
Use Auto-Assign	Rely on the system to pick the next number rather than typing them manually to avoid duplicates.
Export Reports	Regularly export your usage history to Excel for simplified auditing.
