Updated October 2026. Valuation rules checked against the Ohio Revised Code and Administrative Code this month.
As of October 2026, your Ohio parcel number is printed on your property tax bill and your deed. You can also look it up for free by address or owner name on your county auditor’s website. Cuyahoga and Summit call that office the fiscal officer. There’s no single statewide search. The number matters because Ohio taxes 35% of the value the auditor ties to it.

Key takeaways
- The parcel number, parcel ID and permanent parcel number all mean the same thing: one tax parcel in one county.
- Ohio taxes 35% of the auditor’s “true value.” A $300,000 home has a $105,000 taxable value.
- Auditors reappraise every parcel at least once every six years, with an update in the third year.
- To dispute a value, file with your county Board of Revision by March 31 in most cases.
What is a parcel number in Ohio?
A parcel number is the ID your county auditor gives each piece of real property. It links the land to its owner, value, tax bill and sales history. The number stays with the land when the house sells.
You’ll see it under different names:
- Parcel number or parcel ID.
- Permanent parcel number, or PPN.
- Tax ID or tax parcel number.
- Auditor’s parcel number.
Each county designs its own format. Some use dashes, some use long strings of digits. A Franklin County number won’t look like a Cuyahoga one. Copy it exactly as your county prints it, or the search may come back empty.
Is the parcel number the same as the property tax ID?
Yes, for real estate. When a form asks for the “property tax ID” of an Ohio home, it means the parcel number. It’s not your Social Security number or an IRS tax ID.
How do I find my parcel number in Ohio?
Here are four free ways, quickest first.
- Your tax bill. Ohio counties bill in two halves. The parcel number is on both.
- Your county auditor’s site. Search by address, owner or parcel. Delaware County, for example, offers owner, address and parcel number searches plus a GIS map.
- Your deed or closing papers. The recorded deed and the settlement statement list it.
- The county GIS parcel map. Click your lot to see the number and the lines.
Searching a home you don’t own yet? The same search works for any address. Records are public, so buyers often check the value, the tax and the sales history before making an offer.
How do I find a parcel number from an address?
Go to the auditor’s site for the county the home is in. Type only the house number and street name. Leave out “Street” or “Avenue” if the first try fails. If the home is new, try the GIS map, since new lots can take time to show up in the search.
How does Ohio turn value into a tax bill?
The county auditor estimates each parcel’s “true value in money,” meaning its market value. State rules then set the taxable value at 35% of that true value. Your tax rate, in mills, applies to the taxable value.
Here’s an example. A home’s true value is $300,000. Its taxable value is $105,000. At an example rate of 60 mills, the tax would be $105,000 times 60, divided by 1,000. That’s $6,300 a year, before any credits on your bill.
| True value | Taxable value (35%) | Tax at 60 mills | Tax at 80 mills |
|---|---|---|---|
| $200,000 | $70,000 | $4,200 | $5,600 |
| $300,000 | $105,000 | $6,300 | $8,400 |
| $450,000 | $157,500 | $9,450 | $12,600 |
The mill rates are examples. Your real rate depends on your school district, city and levies. Your bill also shows state rollbacks and other reductions, which lower the final amount.
How often does Ohio reappraise?
At least once every six years, the auditor must view and appraise each parcel. In the third year after that, the auditor runs an update based on sales of similar homes. That’s why values can jump in a reappraisal or update year.
Is there a homestead exemption in Ohio?
Yes. It reduces taxes on the home you own and live in if you’re 65 or older, permanently and totally disabled, or a qualifying surviving spouse. Income limits and amounts change, so ask your county auditor for this year’s figures and form.
How do I appeal my Ohio property value?
File a complaint with your county’s Board of Revision through the county auditor. Under Ohio law, the deadline is March 31 of the next tax year, or the close of first-half tax collection if that’s later. Summit County, for one, puts the Board of Revision complaint form right on its fiscal office site.

Ohio parcel number FAQ
Is there a statewide parcel number lookup in Ohio?
No. Each county auditor runs its own free search. The state’s directory links to all of them.
What is a parcel ID number?
It’s the county’s ID for one piece of land. It ties the land to its owner, value and tax bill.
What is my parcel number if I just bought the house?
It’s the same one the seller had. Check your closing statement or deed, or search your address on the auditor’s site.
What does PPN mean in Ohio?
Permanent parcel number. It’s another name for the parcel number, used by some counties.
Can a parcel number change?
Yes, if the lot is split, combined or remapped. A sale alone doesn’t change it.
Why is my Ohio tax bill based on only 35% of my home’s value?
State rules set taxable value at 35% of true value. The mill rates are set with that in mind, so the bill isn’t small.
