> Unified Carrier Registration (UCR) is a federal program under 49 CFR Part 367 that every interstate motor carrier, broker, and forwarder must renew annually. Here’s what it is and who owes it.

## TL;DR

> UCR is a federal annual fee program under 49 USC §14504a / 49 CFR Part 367. Every interstate motor carrier, broker, freight forwarder, and leasing company must register every calendar year, with fees tiered by fleet size.

## Key takeaways

- UCR is mandatory for any entity holding interstate FMCSA authority — including brokers and forwarders with zero trucks.
- It is a separate filing from USDOT, MC authority, BOC-3, IRP, and IFTA — none of those satisfy UCR.
- Fees follow a 6-tier schedule keyed to the prior 12 months of CMV operation.
- Enforcement begins January 1 with no statutory grace period.
- Filing posts in real time to the National UCR Registration System for nationwide roadside verification.

## FAQ

### What is UCR registration?

UCR (Unified Carrier Registration) is a federal program under 49 CFR Part 367 and 49 USC §14504a that requires every interstate motor carrier, freight broker, freight forwarder, and leasing company to register annually and pay a fee based on fleet size. The fees fund state enforcement of federal motor-carrier safety and insurance rules. UCR replaced the older Single State Registration System (SSRS) in 2007.

### Is UCR the same as USDOT or MC authority?

No. USDOT is the carrier’s registration number with FMCSA. MC (or MC-FF, MC-B) is the operating-authority number for for-hire carriers and brokers. UCR is a separate annual registration and fee tied to those authorities — you must already have your USDOT and (where applicable) MC number before UCR applies to you. UCR does not replace either; it sits on top of them.

### Who is required to file UCR?

Any entity operating in interstate commerce under FMCSA authority: motor carriers (for-hire and private), freight brokers, freight forwarders, and leasing companies. Intrastate-only carriers are exempt. If you cross a state line or your loads do, you owe UCR.

### How often does UCR need to be filed?

Once per calendar year. The UCR registration year aligns with the calendar year, and enforcement of the next year’s registration begins January 1. There is no multi-year option — every entity required to file renews annually.
