About UPI

On November 20, 2025, the Mercer County Board of Commissioners approved and passed Ordinance No. 2026 -001, known as the Uniform Parcel Identifier Ordinance (UPI), which will take effect on January 5, 2026.

All documents listed below will be subject to this ordinance.

1. All Deeds, Quitclaim Deeds Declaration of Taking by Condemnation, Sale Contract or Agreement, Notice of Taking by Adverse Possession
2. Right-of-Way, Easement, Ground Lease, Oil and Gas Lease, Solar Lease, Lease Occupancy Agreement, Assignment of Leases and Rents, Highway Occupancy Permits, Memorandum of Lease or other Agreement
3. Mortgage, Assignment of Mortgage, Extension Postponement or Subordination of Mortgage, Release or Satisfaction of Mortgage, Power of Attorney to Satisfy Mortgage

5. Power of Attorney to sell specific real estate, Financing Statement, Clean and Green Application, Amendment or Termination thereof, Declaration of Condominium
6. Any and all other documents relating to and affecting title to real estate not listed in Numbers 1-5 above.

The Uniform Parcel Identifier Number (UPI) will be the Mercer County Tax Parcel Number already assigned to each parcel in Mercer County.

Certification of each UPI Number will be given by the Mercer County Tax Assessment Office (Assessment Office) prior to the recording of any of the above documents. None of the above listed documents will be recorded without prior approval. Any of the documents listed above that are mailed or e-recorded to the Mercer County Recorder of Deeds for recording, will be forwarded to the Mercer County Tax Assessment Office for certification prior to recording.

The UPI certification fee is $20.00 per UPI number certification and will be a separate fee payable to “Mercer County Tax Assessment”. The UPI fee will be collected by the Assessment Office at the time of document submission. There is no fee for the inclusion of the “parent parcel” number on the document. When a portion of an existing property is being conveyed, the property will require two UPI Numbers – one for the new property and one for the parent parcel.

All inquiries and submissions for approval prior to recording should be directed to the Mercer County Tax Assessment Office at upi@mercercountypa.gov.
