Keeping your trucking business compliant is essential, and one of the most important requirements is completing the DOT number renewal process on time.

Many business owners think DOT numbers expire—but that’s not true. Instead, you must update your information regularly through the MCS-150 form, as required by the Federal Motor Carrier Safety Administration (FMCSA).

What Is DOT Number Renewal?

The DOT number renewal process refers to updating your company’s information with FMCSA through the MCS-150 Biennial Update.

This ensures:

• Your business details are accurate
• Your compliance status remains active
• You avoid penalties and deactivation

Do DOT Numbers Expire?

No, DOT numbers do not expire.

However:

• You must update your information every 2 years
• Even if no changes are required, filing is mandatory

Failure to do so can result in your DOT number being marked inactive.

When Do You Need to Renew Your DOT Number?

Your renewal schedule is based on:

• The last digit of your DOT number
• Whether your business operates in an odd or even year

Example:

• DOT ending in 1 → January (odd years)
• DOT ending in 2 → February (even years)

 This system continues for all months.

Requirements for DOT Number Renewal

Before starting the renewal process, keep the following ready:

• Legal business name and address
• Number of vehicles
• Driver details
• Type of operation (interstate/intrastate)
• Cargo classification

Accurate details are critical to avoid compliance issues.
