1) Request a block of inbond numbers from CBP

• Prepare a request on company letterhead including your Filer Code and the quantity of numbers (commonly in increments of 100).
• Contact the Inbond Desk at your local port for port-specific instructions.
• Allow a couple of days or more for CBP to assign your block.

2) Load the assigned block into FasTrax

1. Navigate to Main Menu → Administration → Department Setup.
2. Enter your department Code an at the command line enter: C for Customs Brokerage → I for Info go to Field 4 Starting IT Number:
   • Starting IT Number: first number in the block
   • Ending IT Number: last number in the block
   • Next Inbond No: same as the first number (initially)
3. No need to calculate check digits—the system does this automatically.

3) Daily use & monitoring

• When you create an inbond entry, the system assigns the next available number.
• You’ll receive an alert when you are within 20 numbers of the end of your block—time to request the next block.

4) Adding your next block

• Do not enter the new block until the current block is fully used.
• When the old block is finished, update Starting / Next / Ending to the new block’s range.

5) Multiple departments

If your account runs multiple departments, you can maintain separate blocks of inbond numbers for each.
