MVD-LF631 Form: License Plate Requirements for Manufacturer & Converter

MVD-LF631 Form – In the world of vehicle manufacturing and conversion in Texas, compliance with state regulations is essential for smooth operations. One key document that outlines the rules for using license plates on new vehicles is the MVD-LF631 Form, also known as the License Plate Requirements for Manufacturer and Converter Plates. This guide, provided by the Texas Department of Motor Vehicles (TxDMV), helps manufacturers, distributors, and converters navigate the requirements for standard license plates. Whether you’re applying for new plates or ensuring your business meets ongoing standards, understanding this form is crucial for avoiding penalties and maintaining legal operations.

Released in its latest revision in June 2024, the MVD-LF631 serves as an informational resource rather than a traditional fillable application. It details the provisions under Texas Administrative Code §215.120, ensuring that businesses involved in vehicle assembly or modification use plates appropriately on unregistered vehicles. In this SEO-optimized article, we’ll break down the form’s purpose, eligibility, application process, and more, drawing from official TxDMV sources to provide accurate, up-to-date information as of 2026.

What Is the MVD-LF631 Form?

The MVD-LF631 Form is an official TxDMV document that specifies the requirements for manufacturer and converter standard license plates. These plates are designed for use on new, unregistered vehicles that have been assembled or modified according to Texas Transportation Code §§503.064 or 503.0618. Unlike general vehicle registration plates, these are specialized for industry professionals and cannot be used for personal or compensated transport purposes.

Key highlights from the form include:

• Plate Usage Restrictions: Plates must only be attached to vehicles of the same type being assembled or modified. They cannot be used on commercial prototypes for carrying loads for hire.
• Attachment Guidelines: Plates should be affixed to the rear of the vehicle in line with TxDMV’s Vehicle Registration Insignia rules (§217.27).
• Record-Keeping Mandates: Businesses must maintain detailed logs for each plate, including the plate number, vehicle year and make, VIN (if assigned), and the name of the person controlling the vehicle.

This form is available for free download from the TxDMV website and is essential reading for anyone holding a manufacturer or converter license in Texas.

Who Needs Manufacturer or Converter License Plates?

Manufacturer and converter plates are tailored for specific entities in the automotive industry:

• Manufacturers: Those who assemble new motor vehicles, including prototypes for testing on public roads. This includes commercial motor vehicle prototypes, but with strict limits—no compensated load-carrying is allowed.
• Distributors: Entities that sell or distribute new motor vehicles to franchised dealers, but not directly to consumers.
• Converters: Businesses that modify new motor vehicles by adding, subtracting, or altering components, such as installing special equipment on a chassis. Note that converters handling ambulances, fire-fighting vehicles, or motorhomes require a manufacturer license instead.

These licenses and plates are mandatory for operations in Texas, even if the business is located out-of-state, as long as vehicles are sold or modified for the Texas market. Independent dealers may use similar plates for transporting vehicles to auctions, but converters focus on demonstration, testing, or transport between business locations.

Key Requirements Outlined in the MVD-LF631

The form emphasizes compliance to promote safety and accountability. Here’s a breakdown of the main requirements:

Application and Eligibility

• Apply during new or renewal license submissions, or via TxDMV’s electronic system for additional plates.
• For extra plates, submit a business justification, including vehicle inventory levels, sales history, and plate usage patterns.
• No specific fees are listed for these plates, but general converter licenses cost $750 for a two-year term.

Usage and Restrictions

• Permitted Uses: Testing prototypes on public highways, demonstrating to franchised dealers, or transporting between business sites or repair facilities.
• Prohibited Uses: No signage on vehicles, no load-carrying for compensation, and plates must expire with the license.
• Vehicles with these plates must have current inspections.

Reporting and Maintenance

• Report lost, stolen, or damaged plates electronically within three days. Mark them as “void” in records and destroy or return them within 10 days.
• Return all plates to TxDMV if the license is revoked, canceled, or the business closes.
• Records must be accessible for inspection, with poor record-keeping potentially impacting future plate requests.

How to Apply for Manufacturer or Converter Plates?

The process is integrated into TxDMV’s eLICENSING system:

1. Log in to eLICENSING and select your organization.
2. Choose the appropriate license type (manufacturer or converter).

5. For renewals, ensure all records are up-to-date.

Plates are metal and must meet TxDMV specifications, including reflectivity for nighttime visibility and standard dimensions (12″ x 6″ for most vehicles).

Recent Updates to Texas License Plate Requirements in 2026

As of July 1, 2025, Texas eliminated most paper temporary tags, transitioning to metal plates for new vehicle buyers to combat fraud. This change primarily affects dealers but indirectly impacts manufacturers and converters by standardizing plate issuance. Additionally, a February 2026 bulletin introduced new ID requirements for vehicle registrations, requiring enhanced verification during transactions. No major revisions to the MVD-LF631 itself have been announced, but businesses should check TxDMV for ongoing compliance.
