Data Plate for a Mobile Home: How to Find It, Read It, and Replace It
Your data plate is a letter-size paper sheet inside the home — usually in a kitchen cabinet, a bedroom closet, or near the electrical panel. Here’s how to find it, what every section means, and how to replace it through IBTS if it’s gone.

What Is a Mobile Home Data Plate?
A data plate for a mobile home is a paper label — usually 8.5″ x 11″ — that the manufacturer permanently attaches inside every manufactured home built after June 15, 1976. The U.S. Department of Housing and Urban Development (HUD) requires every manufactured home to carry a data plate as part of the federal construction and safety standards.
Think of the data plate as your mobile home’s birth certificate. It records who built your home, when it was built, where it was designed to be placed, and the safety and performance standards it was built to meet.
The data plate affects everything from insurance to resale value. Without it, selling, financing, or insuring your manufactured home through traditional channels gets much harder. Lenders need data plate information for FHA and VA loans, insurance companies use it to verify the wind zone, and appraisers reference it for accurate valuations.
If your data plate is missing and you order a replacement, IBTS (HUD’s records contractor) sends a copy of the original if it has one on file. If it doesn’t, it issues a substitute Performance Verification Certificate with the same key information — and lenders generally accept it in place of the data plate.
What Information Does a Data Plate Include?
Under the federal standards (24 CFR 3280.5), every data plate must include:
- Manufacturing plant name and address — the factory that built your home
- Serial number and model designation — your home’s unique identifier. The serial number is what most people call the mobile home VIN number, and it’s also stamped into the steel frame.
- Date of manufacture — when your home rolled off the production line
- Wind zone map — Zone I, II, or III rating for storm resistance. Discover your mobile home wind zone and what it means for anchoring and insurance.
- Roof load zone map — the snow and live load your roof was designed for
- Compliance and accessory-load statements — a statement that the home meets the federal standards, and whether it was designed for loads from attached accessory structures like carports or porches
- HUD certification label numbers — the numbers from the red metal tag on each section
- List of factory-installed equipment — furnace, water heater, and appliance makes and models
- Coastal statement — whether the home can be placed within 1,500 feet of the coastline in Wind Zones II and III
- Storm shutter statement — whether the home came with protective coverings for windows and doors
The thermal (Uo value) zone map is technically part of a separate heat loss certificate (24 CFR 3280.510) that the manufacturer must post on an interior surface — it’s usually on or right next to the data plate, so most people treat it as part of the same sheet.
That’s a lot on a single sheet, which is exactly why the data plate is so valuable. For moving and resale, the data plate specs go hand in hand with the home’s real dimensions — learn how to measure a mobile home to see how those numbers translate.
Where to Find Your Data Plate
Finding the data plate for a mobile home is the first challenge most owners face. Unlike the HUD tag on the outside of your home, the data plate is installed inside during manufacturing and can be tucked away in spots you might never normally check.
HUD says the data plate will be in one of three areas: on or near the main electrical panel, in a kitchen cabinet, or in a bedroom closet. Manufacturers have interpreted that loosely over the years, so here’s where to look, starting with the most common spots:
Most Common Locations
- Inside kitchen cabinet doors
- Master bedroom closet wall
- On or near the main electrical panel
- Utility room or laundry area
- Near the back door entrance wall
Also Check These Areas
- Behind the water heater
- Interior walls near the furnace
- Bathroom cabinet doors
- Hallway closet walls
- Inside the original paperwork bundle
In my experience, the most common reason data plates disappear is renovations. Homeowners tear out kitchen cabinets, repaint closets, or replace wall panels without realizing that “piece of paper” is a federally required document. Other times it gets removed because people mistake it for junk paperwork.
If you recently bought your home and can’t find the data plate, ask the previous owners — they may have filed it with other paperwork or removed it during a remodel.
My Search Process
Here’s the search process I use on almost every home I look at:
Start with cabinets and closets. Open every kitchen cabinet door and check the inside surface of each door and the interior walls. Then move to the master bedroom closet — look at the walls, not just the floor. Manufacturers often stapled or glued the data plate at eye level inside a closet.
Check the electrical panel area next. Look on the wall beside, above, or behind the panel. Sometimes the data plate is partly hidden behind the panel door when it’s open.
Bring a flashlight. Data plates are white paper on light walls, and after many years they yellow and blend in. A flashlight at an angle helps reveal paper on wall surfaces. Also look for remnants — staple holes, tape residue, or a less-faded rectangle can tell you where the plate used to be.
Check original paperwork last. Some owners carefully removed the data plate and filed it with purchase documents, loan papers, or insurance records. If you got a folder of paperwork when you bought the home, go through every page.
How to Read Every Section of Your Data Plate
Finding your data plate is only half the battle — understanding the numbers, codes, and maps is just as important. Here’s a breakdown of every section you’ll find on a standard data plate for a mobile home:
| Data Plate Section | What It Tells You | Why It Matters |
|---|---|---|
| Manufacturing Plant Name & Address | The factory that built your home and its location | Needed for warranty questions, recall checks, and identifying replacement parts |
| Serial Number / VIN | Your home’s unique serial number — the format varies by manufacturer, and multi-section homes usually add a letter (A, B) for each section | Required for titling, registration, financing, insurance, and every legal transfer |
| Model Designation | The manufacturer’s model name or number for your home | Helps identify the exact floor plan and specifications for repairs or appraisals |
| Date of Manufacture | Month and year your home was built | Determines which HUD code standards apply and affects depreciation |
| Wind Zone Map (I, II, or III) | The wind zone your home was built for — Zone I for most of the country, Zones II and III for hurricane-prone coastal areas | Determines the required anchoring, insurance rates, and where the home can legally be placed |
| Roof Load Zone | The snow and live load your roof was designed to carry | Critical in northern states with heavy snowfall — the wrong zone means your roof isn’t rated for your climate |
| Thermal Zone (1, 2, or 3) | Insulation level by climate: Zone 1 = warmest, Zone 3 = coldest | Affects heating costs and whether the home meets local energy expectations |
| HUD Certification Label Numbers | The numbers from the red metal tag on the exterior of each section | Connects your data plate to the physical HUD tags — needed for label verification letters |
| Factory-Installed Equipment | Make and model of the furnace, water heater, range, and other appliances | Needed for repair parts, warranty questions, and recall checks |
| Coastal Statement | Whether the home can be placed within 1,500 feet of the coastline in Wind Zones II and III | Placing a home that isn’t rated for it near the coast violates its design limits and can cause insurance problems |
Understanding the Wind Zone Map
One of the most important parts of your data plate is the wind zone map. This small U.S. map shows three zones that set the structural requirements for your home’s anchoring, roof attachments, and overall storm resistance.
Zone I covers most of the United States, including the entire interior of the country. Zone II covers hurricane-prone coastal areas along the Gulf and Atlantic coasts. Zone III covers the most hurricane-exposed areas, such as the southern tip of Florida and parts of the Gulf coast. Tornado country in the Plains is still Zone I — the higher zones are about hurricanes.
Your home’s wind zone is set at the factory and can’t be changed. A home built for Zone I can’t legally be placed in a Zone II or III area. Discover your mobile home wind zone for a deeper look at what each zone means.
Understanding the Thermal Zone Map
The thermal zone map shows three insulation zones. Zone 1 covers southern states where heating needs are lowest. Zone 2 covers the middle of the country. Zone 3 covers northern states like Michigan, Ohio, and Minnesota, where the most insulation is required.
This matters more than most people realize. A Zone 1 home moved to Michigan will have much higher heating bills because it wasn’t built with enough insulation for northern winters. The U.S. Department of Energy has more on how insulation levels affect heating and cooling costs.
If you’re considering a used mobile home, check the data plate first. A home built for Zone 1 that’s been moved to a Zone 3 area will be under-insulated, and a home built for Zone I can’t legally sit in a Zone II or III area. It’s one of the most overlooked issues in mobile home buying.
Data Plate vs. HUD Tag vs. VIN Number
These three identifiers are the most commonly confused documents in manufactured housing. Each serves a different purpose, and knowing the difference matters whether you’re selling, buying, financing, or insuring a mobile home.
Data Plate
Location: Inside the home (cabinet, closet, or near the electrical panel)
Type: Paper label, 8.5″ x 11″
Contains: Manufacturing info, serial number, zone maps, HUD label numbers, equipment list
Purpose: Full home documentation and compliance record
HUD Tag (Certification Label)
Location: Outside, at the taillight end of each section — the end opposite the hitch — about a foot up from the floor
Type: Red metal plate, about 2″ x 4″, riveted on
Contains: A label number (three letters and six digits) proving HUD compliance
Purpose: Proves the home was built to federal safety standards
VIN / Serial Number
Location: Stamped into the front cross member of the steel frame, plus on the data plate and title
Type: Manufacturer’s serial number — not the 17-character format cars use
Contains: Codes identifying the manufacturer and the state where the home was built
Purpose: Legal identification for titling, registration, and ownership
Key Differences That Matter
The data plate is the most complete document — it includes your serial number, your HUD label numbers, and dozens of other specifications on one page. If you have your data plate, you effectively have all three identification records.
The HUD tag (red metal label) can’t be replaced if it’s lost or removed. Instead, IBTS can issue a Letter of Label Verification that confirms your home’s certification. The data plate, on the other hand, can be replaced through IBTS for a fee.
The serial number is the most durable identifier because it’s physically stamped into the steel frame under your home. Even if both the data plate and HUD tag are missing, the number stamped on the front cross member usually survives. For step-by-step help finding it, see our guide on mobile home VIN number locations.
If your data plate is missing, the serial number stamped on the frame — or printed on your title — can still identify your home for most purposes. With it, IBTS can look up your home’s records and issue a replacement data plate or a Performance Verification Certificate.

Pre-1976 Mobile Homes: No Data Plate Required
If your mobile home was built before June 15, 1976, it won’t have a data plate. HUD’s Manufactured Home Construction and Safety Standards didn’t exist until that date — homes built earlier are “mobile homes” rather than “manufactured homes” and were built to varied state or industry standards, or sometimes none at all.
That matters for several practical reasons:
Financing limitations. FHA, VA, and most conventional lenders won’t finance pre-1976 mobile homes because there’s no HUD compliance to verify.
Insurance challenges. Many insurance companies won’t write policies on pre-1976 homes, or they charge much higher premiums, because there’s no documented wind zone or construction standard.
No replacement available. IBTS only keeps records for homes built after June 15, 1976. If your home is older, there’s no government record of its construction details and no way to get a data plate.
Selling difficulties. No financing plus insurance problems makes pre-1976 homes very hard to sell through traditional channels. Most buyers can’t get a loan, and most agents won’t list them.
How to Replace a Missing Data Plate Through IBTS
The Institute for Building Technology and Safety (IBTS) is HUD’s contractor for manufactured home records. It handles data plate replacements and label verification letters for HUD-code homes built after June 15, 1976.
Step-by-Step IBTS Replacement Process
Gather Your Identification Numbers
You’ll need your HUD label number (from the red metal tag outside) or your serial number (from the steel frame or your title). IBTS needs at least one of these to find your home’s records. Need help finding your VIN? Read our guide on mobile home VIN number locations.
Contact IBTS Directly
Go to the IBTS manufactured housing page and choose the label verification / data plate option to order online, or contact the IBTS Label Department at (866) 482-8868 or labels@ibts.org.
Choose Your Processing Speed
IBTS offers regular and faster (rush) processing at different prices. Check its current fees when you order — and know that IBTS charges a research fee even if it can’t find your home in its records.
Receive Your Replacement
IBTS sends a copy of your original data plate if it has one on file. If it doesn’t, you can choose to receive a substitute Performance Verification Certificate with your home’s manufacturing information instead.
Records only exist for homes built after June 15, 1976. IBTS also doesn’t cover modular homes, park models, or RVs.
HUD tags can’t be replaced. If your exterior HUD tag is missing, HUD doesn’t reissue it. IBTS can issue a Letter of Label Verification instead — a separate request from the data plate replacement.
You need at least one ID number. Without a serial number or HUD label number, IBTS can’t look up your home. Check your title, registration, insurance documents, or the frame stamping under the home.
Why Your Data Plate Matters for Financing, Insurance, and Selling
A data plate for a mobile home isn’t just a piece of paper — it directly affects your ability to finance, insure, and sell your manufactured home.
Financing and Loans
FHA loans require the appraiser to verify the HUD data plate and certification labels. Without them — or IBTS replacements — the appraisal can’t be completed and the loan won’t be approved.
VA loans on manufactured homes typically have similar requirements — verifiable HUD compliance, and in most cases a permanent foundation.
Conventional loans through Fannie Mae define a manufactured home as one evidenced by a HUD data plate and HUD certification label(s). No data plate means the home may not qualify for standard manufactured home loan programs.
Insurance
Insurance companies use your data plate to set coverage and rates. The wind zone tells them your home’s storm resistance, and the manufacture date helps them judge its age and condition. Missing information can mean denied coverage or higher premiums. Discover your mobile home wind zone to understand how it affects your insurance.
Selling Your Home
When selling the traditional way, buyers and their lenders need the data plate information to finance the purchase. Without it, you’ll either pay for an IBTS replacement — adding weeks of delay — or limit yourself to cash buyers. If there are title problems on top of a missing data plate, the sale can stall completely.
If paperwork problems are keeping you from selling, our guide to obtaining title for abandoned mobile home covers solutions for common title situations.
Appraisals
Appraisers use the data plate for accurate valuations — the manufacture date, model, serial number, and specifications all go into the report. Without it, appraisers may not be able to complete parts of the manufactured home appraisal report, which can delay or stop financing. Learn how to measure a mobile home so the size on the appraisal matches the home.
What to Do If Your Data Plate Is Missing
I’ve seen a lot of data plate situations — painted over, torn out during renovations, ruined by water damage, or simply lost. Here’s what I recommend:
Option 1: Search Thoroughly First
Before paying for a replacement, search every cabinet, closet, and utility area in the home. Check your purchase paperwork, loan documents, and insurance files. Look for remnants on walls (tape marks, staple holes) that show where it used to be. Data plates turn up in unexpected spots more often than you’d think.
Option 2: Order a Replacement from IBTS
If your home was built after June 15, 1976 and you have your serial number or HUD label number, order a replacement from IBTS. It’s the right path when you need the data plate for something specific like financing or insurance. Check IBTS’s current fees and turnaround when you order.
Option 3: Use Your VIN as an Alternative
For many purposes, the serial number stamped on your steel frame works as an alternative. It’s on your title, and lenders and insurance companies can often work from it. Our guide on mobile home VIN number locations shows exactly where to find it.
Option 4: Sell As-Is to a Cash Buyer
If you’re trying to sell and the missing data plate is blocking a financed sale, a cash buyer who doesn’t need a lender is another route. Compare that against the cost and wait of an IBTS replacement before you decide.
I’m based in Michigan, and most of my deals are in Michigan, Ohio and Indiana — but I buy mobile homes in a lot of other states too. Call or text and ask.
Thinking About Selling Instead?
If a missing data plate or other paperwork problems are making a traditional sale hard, selling the home as-is is one option to compare. I buy mobile homes with paperwork issues, and you don’t have to replace the data plate first.
Data Plate for a Mobile Home: Common Questions
Where is the data plate on a mobile home?
Inside the home, in one of three areas HUD points to: on or near the main electrical panel, inside a kitchen cabinet, or in a bedroom closet (usually the master). The exact spot varies by manufacturer and year, so check all three — the paper can blend in with the walls after years of aging.
What if my mobile home was built before 1976 and has no data plate?
Homes built before June 15, 1976 weren’t required to have data plates, so there are no records to replace. That makes financing and insurance harder. Your options are usually a cash sale or a specialty lender that works with pre-HUD homes.
How much does a replacement data plate cost?
IBTS handles data plate replacements. Fees depend on how fast you need it, and IBTS charges a research fee even if it can’t find your home — check its current prices when you order. You’ll need your serial number or HUD label number. The IBTS Label Department is at (866) 482-8868 or labels@ibts.org.
Can I sell my mobile home without a data plate?
Selling through traditional channels is very difficult without a data plate, because lenders need it for loan approval. Cash buyers, including me, can make an offer without one, since there’s no lender involved. Learn more about how to sell a mobile home.
What’s the difference between a data plate and a HUD tag?
The data plate is a paper label inside your home with the full manufacturing details — serial number, zone maps, equipment list, and more. The HUD tag is a small red metal plate riveted to the outside of each section that certifies HUD code compliance. Your data plate lists your HUD tag numbers, but the HUD tag doesn’t carry the data plate details.
Can the HUD tag be replaced if it’s missing?
No — HUD doesn’t reissue certification labels. Instead, IBTS can issue a Letter of Label Verification confirming your home’s certification if it can find the records using your serial number or label number. Lenders and insurers often accept the letter in place of the physical tag.
Does a missing data plate affect my mobile home’s value?
A missing data plate doesn’t change the home’s physical value, but it limits who can buy it. Since most buyers need financing and lenders need the data plate, it shrinks your buyer pool to cash buyers — which usually means lower offers.
What information do I need to order a replacement from IBTS?
At least one of these: your HUD label number (from the red tag outside) or your serial number. If you can’t find either, check your title, registration, insurance policy, loan documents, or the front cross member of the steel frame under the home, where the serial is stamped. Our guide on mobile home VIN number locations walks you through it.
