A Bill of Lading (B/L or BOL) is one of the most important documents in international shipping. Beyond being a legal contract and receipt, your Bill of Lading number can also be used to track your shipment's progress. In this guide, we'll explain how to effectively track shipments using your BL number.

What is a Bill of Lading?

A Bill of Lading serves three critical functions in international trade:

  • Receipt of Goods: Confirms the carrier received the cargo in good condition
  • Contract of Carriage: Establishes terms between shipper and carrier
  • Document of Title: Represents ownership of the goods

Understanding Your BL Number

Bill of Lading numbers vary by shipping line but typically follow certain patterns:

  • Usually 9-20 characters long
  • May contain a mix of letters and numbers
  • Often includes the carrier's SCAC code or prefix
  • Unique to each shipment booking

Examples of BL number formats:

  • Maersk: 123456789 or MAEU123456789
  • MSC: MEDU1234567
  • COSCO: 6012345678
  • Hapag-Lloyd: HLCU1234567890

How to Track Using Your BL Number

Method 1: Carrier Website

Each major shipping line provides BL tracking on their website:

  1. Visit the carrier's official website
  2. Navigate to their tracking or cargo tracking section
  3. Select 'Bill of Lading' as the reference type
  4. Enter your BL number
  5. View your shipment details
