The manufactured home data plate is a sheet of paper, roughly the size of a letter page, glued somewhere inside your home. It carries almost everything a buyer, a lender, an insurer or a contractor will ever need to know about the house — and most owners have no idea it exists.
It is not the same thing as the HUD tag. That is a metal plate on the outside, described on HUD’s page on manufactured home labels. This is paper, on the inside, and it holds the detail.
Where the manufactured home data plate is hiding
Three locations account for nearly all of them. Check in this order:
- Inside a kitchen cabinet door. Usually the cabinet nearest the sink, on the inside face of the door.
- The main bedroom closet. On a side wall or the back wall, often high up.
- Inside the electrical panel cover. Open the breaker box door and look at the inside of the door itself.
If none of those turn it up, try:
- Inside the utility or water heater closet.
- Inside a bedroom closet other than the main one.
- Under wallpaper or a coat of paint, if the home has been redecorated. It is paper, and people paint over it.
Photograph it as soon as you find it. Then photograph it again, close enough that every field is legible. It is a sheet of paper glued to a cabinet in a house that gets hot and humid — it will not last forever.
What’s on it
The data plate is the home’s specification sheet. Expect to find:
| Field | Why you’ll want it |
|---|---|
| Manufacturer and plant | Identifies who built it and where |
| Model and model number | Needed to order almost any replacement part |
| Serial number | The home’s identity; needed for title, financing, insurance and label verification |
| Date of manufacture | Establishes whether it’s a HUD Code home |
| Wind zone | Determines the anchoring requirements where you are |
| Roof load / snow load zone | Determines what the roof was built to carry |
| Thermal zone | The insulation standard the home was built to |
| List of major appliances | What shipped with the home originally |
| Compliance certifications | Confirms what the home was certified to |
Three of these do real work.
The serial number is the one you will need most. It appears here and is also stamped into the steel chassis. It is what identifies the home for titling, for financing, for insurance, and for requesting a label verification letter from HUD if the exterior tag has gone missing.
The wind zone tells you what the home was built to withstand and what anchoring it requires. A home built for Wind Zone I and sited in a Wind Zone II or III area is a problem — for safety, for insurance and potentially for the park’s compliance.
The roof load zone matters if you are anywhere it snows, and it matters enormously if anyone ever suggests putting a roof-over on the home. Adding weight to a roof built for a light load is not a decision to make from a photograph.
Data plate vs. HUD tag: the difference in one table
This is the most common confusion in manufactured housing, so here it is plainly:
| HUD certification label (tag) | Data plate | |
|---|---|---|
| What it is | Small metal plate | Sheet of paper, about 8½” × 11″ |
| Where | Outside, usually lower right rear | Inside: kitchen cabinet, bedroom closet or electrical panel |
| How many | One per section | One per home |
| What it says | Agency code + six-digit number | Model, serial, date, zones, appliances |
| What it proves | The section was built to the HUD Code | The home’s actual specifications |
| If it’s missing | HUD can issue a Letter of Label Verification | Contact the manufacturer with the serial number |
You want both. A lender or insurer asking for “the HUD documentation” generally means both.
What to do if the data plate is gone
Unlike the exterior tag, this one is often recoverable.
- Find the serial number elsewhere. It is stamped into the steel frame, usually on the front cross-member. It may also be on your title, your insurance paperwork or the original sale documents.
- Contact the manufacturer. If the company still exists, many will supply a copy of the original data plate or the home’s specifications from the serial number. This is the easiest route and people rarely try it.
- If the manufacturer is gone, some records transferred to successor companies, and the state manufactured housing agency may hold some. It varies by state, and it is worth a phone call.
- An IBTS label verification letter, obtained for a missing exterior tag, will also confirm some of the same information.
If you cannot recover it, be honest about the consequence: without a documented wind zone and roof load, some insurers will underwrite conservatively or decline, and some parks will not accept the home.
Before you buy: three minutes that matter
When you are viewing a used home:
- Find the data plate and photograph it. If the seller doesn’t know where it is, look yourself — check the three locations above.
- Check the wind zone against where the home sits now. If the home was moved from a low-wind state to a coastal one, this is a real issue and it is your issue after closing.
- Check the date of manufacture against what you were told. Sellers misremember; the plate does not.
- Check the roof load zone if you are in snow country or if the home has, or needs, a roof-over.
Common questions
Is the data plate the same as the HUD tag?
No. The tag is a metal plate outside that certifies HUD compliance. The data plate is paper, inside, with the home’s specifications. Different documents, different purposes.
How many data plates should there be?
One per home, not one per section — unlike the exterior tags.
My manufactured home data plate is painted over. Can I recover it?
Sometimes. Very careful work with a plastic scraper on a small corner will tell you whether the print survived. If the paint has soaked into the paper, treat it as lost and go the serial number route.
Does a pre-1976 mobile home have one?
Not a HUD data plate, no. Some manufacturers fitted their own specification labels, but there is no federal standard behind them.
